AMD Phenom II X6 1055T & 1090T Reviews

[RaV[666]]

For the price range of 179-285$ ,this chips have more oomph than anyone really expected.
Who expected that they will clock BETTER than C3`s in the same power envelope ?
I was considering jumping to i5 750 a month ago, than two things came to life:
1.1156 has no future.
2.AMD gives me 50% more cores, with better overclockability and no platform change for less than i5 750 cpu alone.

In heavy threaded benchmarks they stood their ground against QC nehalems.In single threaded benchmarks it rarely matters in real life, games are gpu bound .All in all intel probably will respond with some price cuts, thats good folks!

[flippin_waffles]

Rant?

Noted. Unless AMD improves the IPC per core performance, then it will continue to linger behind having to use more cores to match Intel's offerings. This is part of AMD's 'outcore' the competition, though it can only get them this far only. Just look at how far the AMD's competitor six core is at..

This diatribe about the only reason AMD 'having to use more cores' is childish and adolescant. Are you one or both? who decides one philosophy is better than the other, you? I recommend you fire off a few emails to the makers of SPARC Niagra Power etc and teach them a thing or two about how to design and architect CPUs properly. They obviously haven't got your memo!

Nothing strange amigo, that is a summary of how the processors fared in the suite of tests.

this vindicates my choice of the i7 930 (which I bought at the Microcenter for $200 only )

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

[behrouz]

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.

[villa1n]

The 960T and 940T will be Zosma chips, which are nothing more than Thubans with two failed (locked/disabled) cores. Word is that Zosma is unlockable in the same manner that some X2 and X3 chips were unlockable (hell even the Sempron 140 is unlockable). YMMV of course.

"Native" E0-stepping quads with turbo and other Thuban-like enhancements (such as they are) haven't yet been mentioned by anyone of which I am aware.

Thanks for the info. I guess i ll wait for 960 vs 965 comparison.

That's a very good deal, but how much is the 1090T because the i7 930 is actually edging it out in majority of the tests?

250$ on sale

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

[OhNoes!]

250$ on sale

Thanks. A little surprising it's already on sale. So if the 1055T is $150 already, how much are C3 quads going for, the 965 C3 specifically?

[initialised]

Overclocking-wise, pretty well sumarized :





1.5 years later old, good i7-920 (which also can do 4.0 GHz) is still an upper-mainstram king.

It gets worse when you look at crossfire data. I was losing ~10% performance on a single 5970. Got data for dual 5970's on 1090T @ 4GHz to compare with 980X @ 4GHz later.

its actually alot lower than that
on tiger direct they have 2 rebates for the 1055 and 1090, 50$ off, but if you use bing to purchase you get 10% off, so 20$ and 30 on top of that

in theory its 130$ for the 1055T
and 220$ for 1090T
but you have to front the full 200/300$ at first

[vitchilo]

Just a little question... if I have to update the bios so the motherboard supports the X6, will I be able to do it if I don't have another phenom to start it?

[ridney]

x6 is just another phenom ii, so if the bios supports a phenom ii then your x6 would be okay, just so you can update to the latest bios. the x6 only runs at 4x200 multi if it's unsupported, but still it runs which is important

[radaja]

thread ruined again.this is getting so tiresome people

[SKYMTL]

Guys, be aware that while the TD prices are VERY good, they are tied to a mail in rebate that many people have had issues with.

Wasting your time, he has an agenda and is going to stick to it.

[thatdude90210]

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.

[Socratus]

Guyz, need an advice. Still considering about those hexa core badass guyz. Is it worth to buy 1090T or 1055T for $100 less? (I will overclock CPU anyway, mobo will be ASUS Crosshair IV Formula, I don't need much OC, just about 4.2-4.4Ghz max. Afaik, max. HTT is 350Mhz on that board, and 1055T can take the same freq. as 1090T, am i right?)

You'll be limited with the x14 multi on the 1055T, so the 1090T seems to be your best bet. 4.4GHZ seems a bit optimistic for 24/7 though. I've seen 4.2GHZ, prime-stable on water in the AMD section.

There is no free lunch.While intel invested in R&D and upped the transistor count per core(SMT and other improvements) ,AMD used the tweaked 10h core and upped the core count.2 different strategies,each has pros and cons. Either you invest in core logic and have larger and faster (IPC) cores,or you invest in smaller cores but cram more of them inside a chip. AMD will do similar thing intel did,next year with BD modules,upping the IPC and core count at the same time though.

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.

I was talking about BD cores at the end of my post.And nope,the front end will be completely redesigned (call it super front end). The actual purpose of core sharing is to ,as Chuck Moore stated,catch peeks and values and maximize the efficiency of the optimized dual core-as AMD calls BD module. Each int. core is a 4-way OoO machine.There are some conflicting reports as if this is 2ALU/2AGU setup or 4/4 ALU/AGU combination. Only L1 instruction cache is shared,there is a trace cache too. Many other things were optimized,little things,to beef up IPC.There will be a new Turbo Core too,via very advanced power gating. I say IPC and core count will go up with the Zambezi,the power band limit will be addressed via power gating and a whole new process node(hkmg 32nm SOI-just look how Thuban draws the same power at full load as 955BE although they both are being produced on the same process node the difference being low k "tweak" in Thuban's case)

[Lightman]

I'm a bit surprised by the reviews not doing heavy multitasking scenarios like on previous occasions
For instance Game+compress or encode. This sort of everyday scenarios...
Was this a smart thing to do for X2, X3, X4 processors but not for X6??


Anyway I'm getting my new kit tomorrow so I will fill in the blanks


@matose
Very good review! Finally someone has increased NB freq. above default. Kudos to you!

Hey,

You can also overclock both a 2.6 GHz Phenom II 1035T (which also can
do 4.0 GHz) and a 3.33GHz Core I7-975 to 4.0 GHz, select some nice
benchmarks and then claim:


"The cheapest AMD hexcore beats the hell out Intel's $1000,= top of line 45nm flag-ship"........

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...

Thank you very much!

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