AMD 1090T BE Processor and 1055T (Thuban) tested

[Dark4ng3l]

What kind of voltages are acceptable for Deneb CPUs? Is 1.55v really too high and we should expect less of of these things?

I have seen few guys operate these at 1.5 v with good air coolers, may be little higher with custom liquid cooling. Cannot comment on stability and temps though.

Core i7 860 is $230 at Microcenter or around $300 elsewhere. Comparing avg overclock for the 860 at 3.9ghz to stock 3.2ghz X6 Thuban reveals that X6 would need to be overclocked to have any chance competing with a Core i7:

Fritz Chess Benchmark
1055T = 9037 kilo nodes per second
860 OC = 13,897 kilo nodes per second (+54% faster)
*Couldn't find this bench for the 1090T

SuperPi 1.5 XS 1 million
1090T = 21.435 s
860 OC = 10.265 s
860 OC 2 million decimals = 22.901 s (almost 100% faster)

That SuperPi bench is HIGHLY suspect....and why are we comparing a stock amd cpu (that's obviously set up wrong somehow, or that superpi number would be much better lol) with an OC'd i7?

Now, I'm sure the i5/i7 will still be faster for almost everything, even counting apps that can make use of 6 cores i bet the quad intel will be faster. However it's not going to be by 100% or 54% imho.

The great thing about these is that AMD maintained socket compat. (yay!) so existing users can switch...these will be pretty appealing if priced right.... How well will they overclock, as well...And you hafta take platform cost into account. Pretty sure most of us will stick with our i5/i7 but these chips do have potential. :L God let's hope bulldozer doesn't suck, eh?

 

[StinkyPinky]

If the 1055T can push 4Ghz then that's a really good deal for the price. Great deal in fact. The two-core I5's look lame in comparison.

I think these are really exciting chips. I'm not sure why so many people seem to think that if it doesn't outright take the performance crown from Intel, it's not worthwhile or interesting. These seem like they will have amazing bang for buck for certain kinds of users.

People should be very happy AMD is paying so much attention to these Phenom's considering they're not the platform of the future. The 4ghz wall " appears " to have been broken, which is at the most all we can hope for out of the Phenom II with AMDs new platform coming.

An incredible value.

That being said; AMD's idea of Turbo is garbage. I'd hardly blame anything but the process itself for this somewhat awkward 3-Core ramp up implementation though, I'm sure they'd have done more if they could.

 

[Hyperlite]

here's a question: AMD literature always refers to TDP in reference to turbo. Well, how is turbo effected by OCing? If the TDP envelope is already blown, how does the processor control turbo? Is turbo disabled when host clock control is enabled? hmmm....

 

[thilanliyan]

^No apparently it still works. One guy on XS said you can turn Turbo off in BIOS, and also said Turbo crashed him comp when he OCed regularly with HTT since the Turbo speed was too high...so it looks like if you're OCing you should disable Turbo.

I'm definitely gonna get one of these X6s...my Phenom I is too boring now...looks like AM2+ is gonna last me a while yet.

 

[RussianSensation]

why are we comparing a stock amd cpu (that's obviously set up wrong somehow, or that superpi number would be much better lol) with an OC'd i7?

If programs scale well, a 6-core 3.2ghz processor should be faster than a Core i7 3.9ghz (4 cores with virtual threads). Alternatively, we can gauge how much of a performance improvement a 3.9ghz Core i7 holds. If it's >30%, chances are, a 3.9ghz 6-core AMD still won't catch it.

The werd is AMD is introducing a revised lower-capacitance gating technology with Thuban. I would venture a guess 1.55v would be ""Danger, Will Robinson".

1.4v to 1.45v on Thuban may be the 'new' ceiling.

2 flips of a coin here pal..

If they didnt want to compare oc potential... they wouldnt of made it a BE.. :\

I dont know about you, but when i see the words "Black Edition"... it means Overclocking to the MAX!

They brought the black edition simply to cater to a nitche market. They don't care what oces their cpu's get in general. Just look at the Phenom1 BE. They had some of the worst possible oces yet AMD still included a Black Edition model... They didn't care that people were only able to get 10% (About 200mhz-300mhz) oces in general....

I believe they did. Didnt Black Edition come out to combat Intel's Extreme Editions with unlocked multipliers? Phenom I was a fluke considering the previous BE's (Athlon 64's) were pretty good in terms of overclock-ability and Phenom II's went back up in the overclocking scale.

 

[aigomorla]

no the black editions came to help out AMD on there entire PH line when C2D was kicking there butt.

The original A64 BE processors were called FX. I should know i had 2. The FX's were awesome at the time.
They were faster then intel's by a hugh margin..

Those were AMD's original unlocked cpus. However, they costed almost on the same leagues as the intel EE cpus.

AMD wanted to gain a portion of the overclocking crowd back, they came out with a budget BE processor, but by then it was too late.

Intel C2D Arch, really really really slaughtered AMD.
After that its been AMD trying to catch up and not have one step ahead.

The purpose of the locked multipliers was really to counter the widescale fraud that OEMs were doing by taking a lower clocked chip and selling it as a higher clocked chip. For that reason, having a locked multiplier on your highest binned chip won't help, so they are more likely to unlock that model.

One reason I could see them keeping it locked, is to keep people from making their own chip unstable by raising the multiplier too high inadvertantly, and getting too many warranty returns. This doesn't seem like it would be much of a problem, so it is unsuprising that the top binned part does not have a locked multiplier.

 

[Hyperlite]

nvm

I found a another site with them for pre order, not sure how trustworthy they are.

http://www.howardcomputers.com/accessories/detail.cfm?source=googlebase&id=S7817849 242.17. Anyone have any experience with this company?

 

[VirtualLarry]

I agree. CoreTemp has never shown my voltage correctly, and CPU-z has always been accurate. I'd be more inclined to think he really is putting 1.55v into it.

I dunno. On a Foxconn 780G board I have for my HTPC, it says my CPU vcore is 1.89v, when it obviously isn't.

Found some more info regarding oc'ing

http://www.bit-tech.net/news/hardware/2010/04/14/6-core-amd-cpus-overclock-to-4ghz-on-air/1

From what we've seen in the secret testing labs here in Taipei, that might well be the case. We got the chance to see one of AMD’s upcoming 6-core desktop CPUs being overclocked, and the chip hit a whopping 4 to 4.2GHz with a very good air cooler.

That said, this type of overclocking will be limited to Black Edition models, due to HyperTransport limits. As with the original 65nm Phenoms, these new 6-core CPUs will hit around 230MHz on the HT clock before refusing to go any further - so you'll need to use multiplier overclocking, which requires the unlocked multiplier you get with a Black Edition CPU.

 

[Dark4ng3l]

I swear one of the chinese guys who overclocked a 1055 had his bus all the way up to 275...

 

[thilanliyan]

^I think I saw 290 HTT for one of the guys on XS.

Actually this guy got over 300 on a Gigabyte 790FX board using the 1055.

daaaaaaaaaaaayyyyyyyyyyyuuuuuuuuummmmmmmmmmmmmm

these are going to be exciting parts...

wait, what? why are they referencing 65nm phenoms? How/why do they extrapolate that into on OC limit on a mature processes and modified architecture? Or was that just a really poor analogy?

 

[EnzoLT]

Wow, I totally didnt know those things about BE's. Thanks guys.

that is encouraging, if those babies can hit 4.2ghz i believe they'll be trading blows with i7's

OK this is where i need to pull the line on this fuel.

No.. an i7 will smash it... no trading blows.. its called straight up RAPE:

3d06:

Vantage:

CB10:

CB11:

980X is still a long shot to the moon for the 1090. Don't compare it period.

Im trying to be really impartial.. but when you guys feed wrong info, i will step in.

Leave ALL the i7's out of this... the i7 was never meant to be a competition to AMD.
And the i7's are all going to have a nice cache upgrade to 12MEGS later in the future on a 32nm platform.
So... its not wise to compare AMD with an i7 @ performance unless u want to see spanking.

 

[Dekasa]

How about this:

It'll go toe-to-toe with Intel's $200-$300 offerings.
