AMD hexa-core Thuban CPU clock speed leaked

[veri745]

Check the HT clock speed (240MHz), it is overclocked by 20%. That means its stock is ~2.8GHz.

Aha. Hopefully they all overclock as well or better. I wonder what kind of juice it's pulling at current PhII 955/965 speeds.

 

[cbn]

Hmmm.....Six cores @ 2.8 vs four cores @ 3.6 and both having 6MB L3 cache.

I wonder how much better Phenom II x6 will scale? Do encoding programs and Photoshop need less L3 cache per core?

 

[Soleron]

The clockspeeds are actually good news. Not included in the leak was the 1075T, which we can now assume to be 3.0GHz. There's also going to be a model above that the following quarter, presumably 3.2GHz.

Add that to the possibility of a Turbo-like feature (unconfirmed) or that it includes Magny-Cours' IPC boost (which JF did confirm, but we don't know whether that was put in Thuban too) and in Q3 we could have a six-core with single-thread performance greater than the 965 today.

Also in the link below, the quad-core 960T is listed above the 965. If I'm not reading too much into it, the 960T is 3.3GHz; it would need an IPC boost to be better than the 965. So maybe the IPC boost is plausible?

I might be mistaken, but I remember reading some where that the stock northbridge speed on Thuban and that new X4, will be 2.4Ghz instead of 2.0Ghz. If that's true, it would mean slightly higher IPC.

The original source for this listed the system bus as 4000MHz, i.e. 2.0GHz HT.

More important than HT speed is NB speed (because that determines L3 speed), and Istanbul decoupled the two so we still don't know that.

But when JF said there would be a per-clock boost on MC I think he meant over and above the increased HT speed. So if it was to be on Thuban it would be more than just increased HT/NB speed.

The 95W TDP Thubans would be awesome cos some on budget/cheap AM2+/AM3 mobos could just drop em in for cheap hexacore computing if they needed that much CPU power

Yes, we had a thread about 20 days ago about that. I'll see if I can dig it up.

EDIT: Here it is.

 

[konakona]

That's kinda odd. In practice, it has been shown repeatedly raising HT had no performance gains as opposed to CPU-NB. Is it really supposed to give higher IPC? I thought the take away lesson was Ph II had plenty bandwidth to spare in HT running at 2ghz. Maybe not quite the same with 6 cores?

 

[Soleron]

Wikipedia's not a source. I could make up some HT speeds and post them as well.

The stepping listed as 'C4' gives it away. The base design would probably be Istanbul (D0) or Lisbon (D1) since they would already have a die with 6 cores and starting from 4 cores again would be a waste. So Dx or Ex would be more likely.

Come on man you need some kind of source you can't just post things like that with absolutely no credibility.

AMD Phenom II X6 1090T Black Edition
AM3 3,2/3,6GHz Turbo Core 9MB cache,125W

Pretty sure there is not going to be a 9MB cache part (else the server cpu's would have it by now). So I have to consider this inaccurate/speculation.

 

[jacques_derrida]

Also listed here.

Again 9MB cache (if Ön Bellek, means cache). Anyway, seems like the retail price will be around $300+.

 

[aigomorla]

oh nice.. i wonder how much the six core black edition will cost.

if AMD could keep that price below 500, it might even give gulftown a good chase.

Price it over 500, and it will be in the same territory as the i7 970 gulftown, and that would not be too smart.

Keep in mind that PhenomII X4 has 8MB total cache; so a 6 core part with the same (6MB) L3 would in fact have 9MB inscribed on the box.

9MB is referring to total L2 and L3 (6MB + 6x512kB).

Looks pretty interesting. I was expecting the Phenom II X6 to be pretty underwhelming, but if they're priced right I think they'll appeal to a lot of enthusiasts. DDR2 compatibility is nice as well for people who want to drop one into an older AM2 or AM2+ board. I thought I read at one point in time that these were going to be DDR3 only.

 

[Gillbot]

imho, if they come out with DDR2 support still on the hex's that will give AMD a fighting chance at those later adopters who want a more budget minded upgrade.

 

[lopri]

I think at least one model (1055?) should be below $300 to have a chance to fight i7. It would be awesome if it's backward compatible with AM2+ platform as well. At least for those who actually use all the cores.

 

[jacques_derrida]

Seems to be official:

1090T Black Edition: 125(W), AM3 Socket, 9MB Cache, 3.2 GHz Freq @ 295 USD
1055T: 125(W), AM3 Socket, 9MB Cache, 2.8 GHz Freq @ 199 USD

[VirtualLarry]

That 1090T BE looks SWEET! I think I'll get one. 3.2GHz stock, with 3.6Ghz Turbo (that's pretty impressive for AMD), and SIX cores. SICK!!!

Interesting. Especially 9Mb L3 part.

P.S. Derrida @AnandTech? That's something very différant.

Edit: It looks like 3Mb L2 and 6Mb L3.

 

[Markfw]

If I can get a 2.8 ghz hex core that fits AM3 for less than $200 , I will trash my failed 550 BE OC, and get it, just to play with !

I'm thinking AMD is going after the "I want more cores/more cores = more better" crowd. Plus, if they keep socket and "older parts" compatibility, this will give Intel a serious run. People will buy them just because, whether they perform better or not. I mean, if it has more cores, it HAS to be better right?

 

[grimpr]

Would you prefer the Intel i5 670 at $279.99 with some 32nm moist cream instead? Real cores for me please.
