woop nice figs where are the dam laptops based on it?
Thanks for the links onethreehill....
Anyone that got the time to make a power measurement comparison?
Gotta get to class! :D
Really crushes the Atom, about damn time... would make a netbook / ultra-mobile much more attractive to me now, esp. if priced right

Almost equal performance to a SU2300 + ION with much lower energy requirement nice...
about time :D
cant wait for a tablet with this chip
I hope Intel intros that single core + HT sandy bridge CULV that i had heard about some months ago. That would be a very good match up against the Bobcat. A single core + HT SNB would certainly be energy effective enough and the original plan that i heard was that the GPU would be the same as the other CPU's.
The new GPU and CPU with dynamic clock would totally work out. But i have not heard anything about it since then the last i heard was about dual core SB based CULV's with lower clocks, which is sad given the added silicon and lower clocks.
You are welcome :D

Can someone explain what the Anandtech article is trying to do? He's saying that there is disappointment when compared to the dual core Pentium. Isn't that a completely different class of system as far as form factor and power consumption?
Maybe I'm ignorant of such things. :confused:
god dammit! why isnt there an option with fast cpu and slow/cut down gpu???
Seems like someone was wrong about power consumption. :D
So late in my country (2:57am). Worth my time.
Now who could that be? It's a bit of a shame to not be able to see what his respond would be.
Looks to be a good platform, I'm actually really interested in buying one of those as my girlfriend isn't moving any time soon which means 6h of sitting idle on a train every two weeks.
Anandtech has a very strange review and conclusion, they mention that the system is much faster and healthier then any Atom yet the cpu benchmarks show a different idea because those are favorit HT benchmarks, I own a n455 with 2gb ram and ssd and it is ok for general usage, but its slow when loading things, even my ssd wasn't able to make it shine i.s.o the 7,2K sata2 hd. so it is clearly cpu limited. would like to see real world compare loading apps, and battery time. Atom has a very low TDP yet when you look at power consumption you see higher consumption then brazos.
In most of our benchmarks the performance advantage over Atom isn't huge, yet using Brazos is much better than using an Atom based machine. It all boils down to one thing: single threaded performance. Atom can make up for its deficiencies by executing a lot of threads in parallel, but when you're bound by the performance of a single thread the E-350 shines. The E-350 is 65% faster than the Atom D510 in the single threaded Cinebench R10 test. It's this performance advantage that makes the E-350 feel so much quicker than Atom.
AMD give us the 25W rated brazos in notebooks and netbooks.
yeah i stopped reading the anand review, it was bs. none of the cpus or tests made any sense. all the other reviews were great though! i thought the cpu would be a bit more powerful, but given its power draw...well you just cant beat it.
Anandtech tests the platform as a full desktop platform.
Without actual power consumption, the platform is of course not great in pure performance view against desktop systems.
Hmm... is it? ASUS Eee PC 1015N (N550+ION2) has very close performance to the highest boobcat and consumes 8.5-15W depends on the load. Btw, the notebook available on newegg just for $419 and has 9.5h of battery life. Also I really doubt we will see $500 netbooks with 128GB SSD soon.
Looks like the early BOINC scores weren't even close to being representative.
its look promising
http://www.netbooknews.com/6742/dual...n-benchmarked/
In techreports review most of the scores between bobcat & N550 were pretty close. But keep in mind that bobcat was tested with SSD, so I would want to see how it performs with 5400 RPM HD and 1GB of memory (like in 1015PN)
lol wut.. so anad reviews didn't make since for the last 3-4 years. :rofl:
Hes using this benchmark setup for pretty much 3-4 years now, i like how he gets bashed more and more for doing the same thing bractically changing nothing with his benchmark setup. Plus most of the other sides pretty much use the same benchmarks and they show nearly the same results...
If you want to critizise a review then that of legit reviews, it has no consistency, they add and remove systems or do no compression at all.
You can if you concentrate on certain sub systems like the CPU, most scores of the CinebenchR10 benchmark are very consisten accros the review sites, same goes for the x264 benchmark. But if you start to compare the whole system I agree with you.
@ reviews
Amd really did some magic with the idle power consumptionn, its really really good. Compared to the Atom platform its needs ~70% less power. :clap:
Idel runtime swill be crazy for this platform, I hope the OEM don't use this fact and save on the capacity of the batteries.
The cpu part on the other hand is not that impressive, it needs 2-2,5x (~10W compared to ~4W on atom) more power then atom and delivering more performance in the range from 10-80%, avarage performance advantage is hard to tell but i guess its somewhere ~40%. But at least this really doen't matter that much because of the awesome idel power consumption the barazos platform has and overall load power consumption is in the same range as atom.
The IGP is very good for its intended market, thought the limited memory bandwidth eats more performance then I thought.
Overall the plattform is a real winner for the ultra mobile market. :cool:
Low cost entrie desktop and lowcost main stream books (15") i am not so sure if the performance is enough, since in this segement power consumption is still not the main selling point and there are already dirty cheap Pentiums and Celerons batteling (and even some i3s) the sub 500€ market.
Now what i really want to see is how the C-50 performs, cause that is the CPU that will go against the N550.
N550 is lower speed then D510 right? 1,5 vs 1,66ghz at least according to official intel specs:
http://ark.intel.com/Compare.aspx?id...54,49669,49491,
but yet if you look at PCperspective review the D510 is kicked very badly on any part against brazos, with same amount of ram and same ssd disk. So how can a N550 then be even close to the one reviewed????
http://www.pcper.com/article.php?aid=1039&type=expert
so your source has 0 added value to this compare.
Seems a bit slower than expected, but also way less power usage than expected. Even the "high end" zacate seems more of a netbook than notebook part. Seems to blow away everything in perf/watt.
Do want.
Can you please stick to the reviews that actually compare power consumption and performance between the two?
In techreports review the difference is very big between the two.
Zacates performance compared to Atom 550 according to the Techreport:
Javascript: 175%
7Zip: 111/108%
Tryecrypt: 132%
x264: 133/118%
Call of Duty: 293/235%
Far Cry 2: 144%/230%
Never slower, and up to 3 times at fast at graphics intensive tasks, and that is when Atom has Ion. In CPU intensive tasks Zacate is 8-75% faster. In singlethreaded benches we see bigger differences than these multithreaded shown above.
When it comes to power consumption Zacate is overall lower than dual core Atoms.
And yes, the comparision isn't entirely fair, but it's safe to say that the performance difference is huge, and general usage with singlethreaded apps probably would increase the lead. Lower power consumption, especially in idle is also a big advantage.
You simply can't say that the performance is similar, or hint that Atom would have much lower power consumption. You don't have any solid base for these claims.
looks like a real winner, and much better than i expected in power consumption (idle power draw is impressive)
it completely destroys ATOM in performance but i didn't expect it to do the same in power consumption!
PS: close up of that 10+hours MSI netbook:
MSI Netbook in Techreport review
i'm 100% sure that i'm going to get a netbook based on this platform next year as i don't need the power and screen of my E6410 all the time, maybe dell is going to release a latitude or vostro system based on this :D
This will be great upgrade for my wife's Aspire One with Atom N270 and G965.
Really impressive perf/power/die area considering usual AMD offering in these markets.
Looking forward to proper nettops and laptops test soon!
Was about time :D. Performance was expected but power draw numbers are amazing! With the L2 working at the half the CPU clock,having "lowly" 2 issue decoder/front end ,sharing the memory controller and many other power optimizing features,it's actually amazing to see this level of performance. I hope AMD manages their goal of close to 10 hours of resting battery life,there is still time to tweak the platform a bit.
These will get SERIOUSLY interesting at 32nm.
Im waiting for an Alienware M11 based on Llano, 400+ shaders should wipe the floor with that wimpy nvidia 335M. Will do lots of shopping next year =D.
sometime i think that anandtech reviews are written by complete idiots who don't have slightest idea what they are talking about lol
Like testing netbook chip in heavily multithreaded applications?The ones that won't be used on this platform in real usage scenario? :D
In any case,Bobcat runs circles around Atom with lower power draw.He can use 3DS Max and Cinebench all they if we likes,it won't change this fact,even in those cases ;).
AMD will use 28nm node for "Brazos II" ,codenamed Wichita and Krishna .These will use the "Enhanced Bobcat cores" and up the core count to 4. I suppose the GPU will be beefed up,to say 160SPs ? :) So,all in all,more cores,faster cores(both x86/GPU),less power.Quote:

From the tests, it looks like the nano dual core beats it in every way, except graphics...
ye so I just learned I thought they would use the same process as bulldozer but 28nm should alow for some serious improvement indeed. Damn 2011 will bring somewhat of a revolution on netbooks, soon well be talking about gaming performance on these platforms and thats awesome.
nano is a power hog, idle power usage of nano is very high, nano is good for nettops but i just don't see this thing in a a netbook because it draws way too much power in its current state, additionally it is a 3 chip design with a huge formfactor on both the NB and SB (real estate of the VN10000 northbridge alone is bigger than Zacate + hudson M1)
The current Nano *is* a 65nm design - you can't blame them for process size. TSMC/GloFo have their hands full as it is without VIA trying to get on the 45/40nm boat...
Indeed - I initially thought performance woud be higher but considering the level of neutering that has been applied to keep power low it's still amazing performance.
Now I'm just waiting for Sony to put one inside one of these:
http://laptoping.com/wp-content/092009/sony_vaio_x.jpg
:D
Brilliant, seriously. Also, the huge single threaded advantage over Atom counts a lot. When a program is multithreaded, it doesnt feel that sluggish on an Atom, but single threaded programs feel SLOW. Thats where the performance difference will be most felt.
Great job AMD
So why do all the reviews, besides hothardware, compare this to the atom D510? I was hoping to see a D525 w/o ion (at least hothardware compared the ion2 D525 against this) comparison.
I only skimmed the articles, but I didn't see if AMD will release mini-itx type baords to compete w/ ATOM/NANO. I guess that'll happen later?
The Nano isn't that amazing when you look at the total system power or silicon to get there. The APU by AMD is 74mm˛ in 40nm which include NB and GPU. The VIA platform has 136mm˛ CPU and a 100mm˛ GPU/NB. If it were on 40nm process with perfect scaling these combined would be 89mm˛ (236 x (40/65)˛ or 51 + 38mm˛). And that is assuming both the CPU and GPU/NB gets to shrink. It is however somewhat competitive and will offer an alternative which is good IMO.
When I said close to N550, I meant that the perf of bobcat still in the Atom category. It is barely faster then lowest end C2D 1.2GHz celeron, so I don't really understand what AMD meant when said "90% of today's mainstream performance" 1.4GHz DC celeron or 1.6 GHz Athlon is not a "mainstream performance" at least for 4 last years already.
Any way my point was that in all reviews pwr consumption was compared to desktop systems (Atom D-series doesn't support SpeedStep for example). So it worth wait and see an actual netbooks on bobcat before draw a conclusion. 9W-11W at idle seems to me a bit too high for tablets. My Asus T101 (N450) consumes ~4.5W from the wall socket at idle.
First you need to define idle to talk about idle consumption. idle IE8 window open, idle by closing laptop, idle by typing in word or somewhere else. (also the screen/screensizes should match, as the connected hw. if for example the powersavings didn't shutdown the fan on the testbed this would already make a difference, same with brightness of screen, same with an usb mouse etc etc. Considering all this, the preview pre release platform is already impressive for the zacate. (curious when the gpu throttling software will be optimized and how the lower end parts will perform).
It doesn't need to be alot faster than celeron if it can outdo it in gpu (which is the case) and have a better power profile which is also the case then it is a job done for a starting platform. (and is probably a lot cheaper to make also).
Performance is not in Atom category... performance is near celeron DC performance. Atom is only close in heaviliy multithreaded tasks, but the moment something has to be done single threaded it is not even competition. which is one of the headbreakers of Atom.
Idle means on, but not doing anything. Closed laptop lid means standby. It's defined well enough. Either way, it looks great. Out of order design is also welcome. Plus the idle consumption is very low, almost half the Atom platform. Makes me want to have one such netbook :D
You forgot that brazos also targets lowcost notebooks (sub 500$/€), especial the chips in question (E-Series). For that the comperison with Pentiums/Celerons and also multithreaded apps is valid.
The real netbook chips are the C-series.
Its just like with the Atoms-> D for desktops Z/N for Mobile
While noone stops a OEM to put a D or in case of amd a E into a netbook, its not the main target of that cpu.
On a side note:
Kinda funny observation, suddenly you hear form the same guys, that usually proclaim single thread performance has no relevance in todays usage scenarios, are all over the superior single threaded performance of brazos compared to atom... :D
World is not as black and white you seem to think. Multi/singel performance importance is dependent in usage situation. With netbook/low power laptop, I would not see anyone really using anything that really is multithreaded. Situation is entirely different when we speak of desktop/high performance laptops. There is nothing contradicting in it.
All sort off... you get C2 based Pentiums/Celerons or Westmere based Celerons/Pentiums in that price segemnt.
Celeron U and Pentium U comes to mind for el cheapo subnotebooks or if you move to normal sized notebooks you have the Celeron P or Pentium P
The U even have the same TDP as the brazos platform.
So its kind of a tough market where Brazos enters, netbook market we have a winner but the other targeted markets are not a sure victory.
that should be filled by llano i think.
as you go into bigger things, the low tdp of a cpu becomes less important. and you might get away with throwing in a cheap cpu to keep costs down (at a major perf cost) the cheapest llano, duel core and slow gpu, should be for those sub 600$ laptops around 13-15"
yes i know its still a little ways off too
No, AMD didn't do any magic with the idle power consumption
Atom D510 and all other D series lack speedstep technology . Thats why Zocate had much lower idle power consumption
However, Atom N series (like Atom N550) does support speedstep. So far I didn't see any chart that compares the power consumption of Zocate with N550
Here you go,the N series single core Atom based system(with turned off panel for all systems tested) has higher idle power than (un)optimized dual core Zacate ES @ 1.6Ghz :
http://hothardware.com/Reviews/AMD-Z...review/?page=8
why no reviews of the 9W system?
do we have to blame AMD for the fact that Intel doesn't introduce speedstep in there lower end systems... hey it would only create longer battery life, no thx we don't want that intel :D
TDP means nothing, actual power consumption is what matters check the PC perspective review how much the SU2300 and atom D510 actually consume against there rated TDP
D510 is a 13W rated cpu remember, yet it consumes more then a 18W rated tdp and i will skip the idle compare because of the lack of technology implementation :D
SU2300 + ion is 10+12
http://ark.intel.com/Product.aspx?id=43098
OK! You buy Atom based netbook and I will buy Zacate based one.
You will have very efficient toy which can't play 1080p youtube without dropping frames and I will trade few minutes of my battery to at least get decent experience ;)!
In the end more choice is better for everyone.
Intel might just have to make the atom good for once, even if it does gobble of more of their notebook chip sales.
There's no way to win this. If their design is a power saving demon, people would rather it be more powerful. If their design is a performance demon, people would rather it be more frugal with energy. If they strike a balance, people would complain that the platform doesn't shine in a way that is worth any attention.
I also don't know how many of you bothered to read it, but I haven't seen much mention here of AMD's projected idle power in the final platform of about 6W, down from what today's write-up shows.

I don't know how he got that values cause those are really bad, atom books are idel usually in the 6-8W range (with screen on). And even the Desktop Atoms (D) idel in the 12-14W range.
Some values:
N550:
Idle: 6W (max 8W)
Load: 12W (max 14W)
http://www.notebookcheck.com/Test-Ac...0.39633.0.html
D525:
Idel: 12W (max 13,5W)
Load: 26W (max load 31W)
http://www.notebookcheck.com/Test-As...k.37498.0.html
And for duploxxx:
Again D-series isn't for netbooks. Thats why it hasn't any energy saving features. I don't know why intel does this, but you usually don't find D series in netbooks.
@consuming more then the rated TDP.. yeah if the whole system would be meant, but its only the chip itself.
http://www.notebookcheck.com/Test-So...k.33629.0.html
Idel:10W (absolute max 13W)
Load:27W (absolute max:32W)
or
http://translate.google.com/translat...53-u341cc.html
Idel:7,5W
Load:21W
Those include Wlan On, screen at full brightness, so yeah im with you actuall consumption counts much more, but I doubt you can cram in all other components in the remaining 3-9W.
1.6Ghz Bobcat is competing rather well perf. wise with 1.2Ghz CULV Core 2(45nm) based part as can be seen here:
http://www.pcper.com/article.php?aid...e=expert&pid=1
That's not bad at all taking into account how tiny the Bobcat cores are compared to Penryn and also the 2way Vs 4way OoO designs of these two products. Power draw is no contest since Zacate is in its own league.
Is it possible to add some 256MB DDR3 1600 as sideport memory? That should help the igp performance. Or at least as an option to OEM's.
will only be able to compare once they also have material to review....
looking at the specs of the N550 atom laptop with 1GB ram, 10.1inch and 5400 rpm i hardly doubt it will consume more...
and while the N550 will probbaly consume less then the E-350 it is slower or equal in cpu always slower in gpu... and once working with it how long do you tink the battery will last if it requires much more cpu power to do something with it...
http://www.pcper.com/article.php?aid...e=expert&pid=7
lets hope we get some good platform compares soon, all I see now is that there is more competition which can only improve the consumer choice and price.
I agree, but it kinda hard to do good plattform reveiws espeical on mobile platforms.
I hope wee see from some big OEMs books wiht bowth platforms and simmilar specs, this would provide the best comparison.
the ratio of perf/watt + future proof (dx11 + open gl) is what's going to make bobdog (cat I mean cat) a much better option
Adding another memory channel (either Sideport or main memory channel) will not give it anymore advantage. In IGP / GPU-intensive tasks, Zacate already blows out it competitors. In other tasks, the added logic will consume power.
I am looking forward to more info as I am planning to buy a new nettop with Zacate inside.:D
I have to agree with you there. I'm looking at a tablet PC
HP has one with a CULV and 6.5 battery life on website. So if AMD new Bobcat can get over 8 hours and be that close it is a win and I hope HP or some other manufacturer will make a tablet PC with it. Just what I'm looking for.
This seems like a winner, make it cheap & widely available AMD, i'll buy one for my wife next year if there's a solution for less than US$ 300 budget netbook, sold in my country. :D
Yes, it is Ironic, but a key point would be that it's at this performance level that single threaded perf is actually noticable and effects user experience.
In current mainstream desktop situations (~3ghz slow cores, vs fast cores) it's almost impossible to tell the difference.. except, say, a heavy PDF doc that might be chunkier to scroll through on anything but a fast core
there is a slight difference between K10 @ 3ghz vs. i7 @ 3ghz and ATOM vs. bobcat...
i feel no difference at all between my 1055t @ 2.8ghz/2.0NB and the 1055t @ 3.9ghz/2.7NB in desktop user experience, in fact it hardly comes out of Cool n Quiet state when browsing the web, watching HD movies etc. (due to my OC my CPU has a CnQ clock rate of 1.1ghz)
only things were i can feel a difference: Cinema 4D (rendering only), gaming (scaling stops @ 3.2 ghz with my overclocked 6850 @ 1050/1200 in most games), 3dsMAX rendering only
on the other hand ATOM is barely able to cope with windows 7 due to its anemic single thread performance, it's even worse than a 8 year old athlon XP in this regard (Windows XP on my friends 2.4ghz P4 runs smoother than on his 1.8ghz Atom HTPC (with ION)), bobcat on the other hand seems to be slightly below Dual Core K8 performance...
you only have to take a look at single thread performance (tests) to notice that ATOM completely sucks in every way you can look at it, sure bobcat isn't a good performer but at least it gives you the possibility to do something else besides texting and browsing low res flash content on the web....
Do aprove:up: Single threaded performance is great. Where it's really going to shine is in gaming and it does show. I think APU's is the future. in 10 years average Joe gamer might not need a discrete graphics card.
so what happens when we overclock it and give it more ram and/or play with ram timings? :)
Looks promising. Staying tuned for the pricing. It must be much better than Atom + ION! :D
some of the specs of systems coming from both camps...

By hectorjacob
1,6/1,8 husky 32 core :) nice laptop in a 35W package...
Ontario is 40nm...
TDP is not rated power draw, it is relating to heat created by the chip and the rated cooling required for it.
in that chart that I posted , the are some typos but gives you an idea of what segment AMD is going for...
LLano is a 2-4 cores, that 32 core is a typo, and Ontario is 40nm, not 32nm that is correct.
Exactly my point. Single threaded performance becomes less important when it gets to a certain level. At the level of Atom, day to day single threaded tasks seem slow. Thats where Bobcat shines, not to mention greater multithreaded performance too while consuming less/equal power. Whats the complaint?
in terms of cpu performance sandy bridge would totally ride the husky :D but the interesting thing is that retailers putting Ontario on the same plane as CULV Sandy bridge. The CULV sandy bridge is no slouch in either GPU or CPU terms "Less CPU than GPU" i dont know how die wise Intel will win expect use the original plan and launch a single core Sandy bridge already :(
I dont know why they dont put out a single core sandy bridge against the likes on Ontario, i saw really good single core performance from a few core disabled cpu i dont think single core with HT running at a high speed would run into much problems?
