AMD Phenom II X6 1055T & 1090T Reviews

[Dresdenboy]

Actually, if you're talking about BD "cores", not modules of 2 cores, the ipc and power will likely go down a little, as the core count goes up.

Think of it like:

Take K10 core. Now *share* the L1 and L2 and decode with a second core. (lower performance, but you get lower power). The FP is about the same (vs K10), double the width, but shared between the 2 cores. FMA will help some apps, clearly. But in general, I expect each core will have decreased IPC, power and area vs a K10 core, but they'll try to put more of them on a chip than with K10.

Bookmarked.

L1 D$ won't be shared, but L1 I$ will. Decoders will be less restricted than K10's, and wider. FPU will be very different, we have to see how it performs, but very likely with better performance per core than in K10, (with a probability more than 50%) even without FMA. Each core might have decreased IPC (not so likely), but overall design aims at better scalability. And more cores seems to be the way to go. Intel already demonstrated designs with tons of cores.

That was only made to show some Clock for Clock comparison and no body said anything about value for money , you dont have to turn it into some fan-boy arguing point

Although his quote might seem little odd/kinda off topic from what hes saying. Try re-reading his post with out the quote.

I think the point is saying a $200 overclocked cpu is better than overclocked $1000 cpu in some cases isn't "always" a fair statement.

Why do reviewers always skip on north bridge speed (L3 cache)...?

+1

I'm hoping hardwarecanucks can also show difference at say max stable core with default NB and max stable OC NB.
I can also hope for some teasers screen shots, and a cookie.

He was saying it is unfair to compare the 1090 to the 920 when the 1035 can get the same clock and sold to a much cheaper price and at the same time you can compare it to the 975 which can also do 4GHZ and much more expensive


I say take that clock for clock comparison and get whatever Setup for your budget/needs then add or take 10% from the performance because you probably wont run the same exact overclock , for me it is always about clock per clock coz i will be overclocking it anyway

[Lightman]

Thank you very much!

I'm very curious about the explanation of the very poor single-threaded performance compared to Deneb.

Yes, indeed!
I have some numbers from my C2 Deneb so I will compare them to 1090T at the same clocks. Only difference will be RAM because I've moved to DDR3.

Actually he said it was equally fair, in that both were useless comparisons when factoring in performance per dollar. So if you are looking for setups on your budget, wouldn't the cost for performance be the number one factor?

I would take the cost of performance for sure as number one factor but others might pick more expensive choice with higher Multi for easier overclocking if it fits the budget anyway and the BE might turn to be the best seller for X6 here in XS for that reason

That would be just as (dis)honest as overclocking a 2.66 GHz Core I7 920
and a 3.2 GHz Phenom II X6 1090T to the same 4.0 GHz...

That is what i understand from this , it is unfair to compare the 920 to 1090 at 4GHZ ,, if i misunderstood it then sorry for my bad English

My initial thoughts would immature bioses not tweaked fully yet for Thuban to shine fully.

Can you check the memory and cache latency/bandwidth figures of Thuban and Deneb?

[savantu]

id say intel's cache thrashing is a bigger problem than amd's six cores competing for a "smaller" L3-cache.

Can you detail a bit about this "cache trashing" ? The whole purpose of Intel's cache structure is to minimize trashing.

[richierich]

I know...

You stated .rar wasn't used much, well it is. But normal zips are even more used then rars. 7zips are not very common, altough they have superior compression.

I said WinRAR wasn't used much, heck probably the built in Windows Zip program is used the most, worldwide.

u can get a 1055T for 150$ from tiger direct, what you do u think of that price/perf?

its great when you get a sale, but your trying to blab about how perfect things are just cause you got something for a deal, the rest of the world may have to pay actual retail prices and should be looking at reviews based on that fact

Tiger direct has the least reliable rebates out there by far. Look it up on the internet and almost no one gets there rebates. To make matters worse, isn't the price of the 1055 in trays of 1000? If this price is 199, I don't think tigerdirect, which typically get lambasted by pretty much every person out there would be doing such a good will move and take a 50 dollar loss.

Yeah, Tigerdirect rebates are somewhat notorious. In other words, good luck getting it.

The x6 looks interesting, but I don't want to change mobo. I have the Asrock 780GMH/128 (running a PII 945). The latest bios is from Dec 2009, so I'm not sure if it'll work.

Tigerdirect is infamous for deceptive advertising and ripping off customers, especially in Canada. I would not trust this rebate for a second.

[richierich]

People have already stated that the rebate company is valid. All of the old TD rebate nonsense is still out there on the internet, unfortunately.

[vitchilo]

Finally cancelled my order for the 1055t and went for a 1090T...I'll only have it monday morning... NOOOOOOOOO

the form used for the rebate is the same exact one i see on newegg, so i believe it is ok.

i7 920 vs X6 1090T:

http://www.anandtech.com/bench/Product/146?vs=47

The 920 still wins in most benchmarks but not by a huge margin

The direct compare is sorta irrelvant or is gaining irrelevancy in my opinion because the architectures and core counts are starting to differentiate on work loads for DT.

What I mean by this is that it is slowly evolving not into who wins, but who wins what and at what cost to the end user. The 1090T is just a great release by AMD in this round.

[JumpingJack]

if AMD invested some of Tech for converting 6 core to 3 core with Hexa thread , we would see better situation in Most of games.

I really doubt that.... it does not work the way you are thinking.

Actually looking back and sobering up after looking at reviews. Intel really doesn't need to do a thing. Sure multithreaded performance is good on this chip and better than intel offerings at times, but for most people these instances don't pop up enough and Intel more often than not is the better choice because these highly specialized multithreaded scenarios just don't pop up enough.

Thuban really reminds me of Fermi in alot of ways, late compared to the competition, faster at times, but generally not worth the wait or hype.

Intel needs to add 2 more cores to their quads and slap on 50% more on what their currently charging, just like AMD. At least I can dream, right? They have 8 cores on 45nm at 130W, so 6 cores with a clock bump should keep them under that power envelope. Yes, I know it won't happen, and it sucks. Oh well, someone has to pay for R&D at 32nm and so forth.

With triple channel already in place, they have all the mem bandwidth there already.

[charged3800z24]

Oh My!! people, get over yourselves....

I see AMD guys posting test from sites where AMD shines, and Intel people posting test from sites that favor Intel....so who is really right here??
The reviews are mixed and show different results. something is obvioulsy different in the testing methods. I have better winrar scores with my 965 4core When you OC via bus speed the NB / UnCore increase which I know improves performace on my 956. When they do OC test and only up the multi on the Phenom and not the NB they are loosing performance gains. Not that it makes some huge increase, but still noted. I will wait for Chew* and others to post results and see what these chips can do. I only look at review sites for a hint of the picture. Most do not have great comparison due to the given hardware they have to test with. some boards have better power saving, some don't. So things will be different from different sites

I think it's pretty simple..

really heavy multi threaded apps = X6 1090T > i7 930
others apps = i7 930 > X6 1090T

IMO those thubans are for the encoding/rendering guys who can't afford an i7 980X

i like those charts, shows how good as a platform AMD has really come.

-- Intel launched i7-980X a month or so ago, but they slapped on way more the 50%

I am wondering if Intel may not accelerate their plans to produce the i7-970 at a ~300 buck price point sooner rather than later, rumor mill has it pegged at Q3 -- that is a long time to let AMD woooooo people over to their platform.

Not worth what hype? The extra cores do what they are supposed to in multi-threaded scenarios and the turbo works great. This is a nice jump over Phenom II and a great upgrade path for AM2+ and AM3 owners. Can you point me toward something Thuban didn't deliver on?
