_Gtech, every post or thread I read by you, makes my belief stronger: You have no credibility at all.
It's not any of my business what people think of me, truly...

I'm going off-topic here, but I find it interesting what happens in the background to skew performance results. For example, an i7 920 clocked at 4.4 GHz and a 1095T clocked at 4.4 GHz has the 1095T outperform the i7 920 by 20 GFLOPS in integer performance. The only time you see this gain sigificant is in games such as Farcry 2 that actually make use of the extra cores or focuses solely on integer performance. But this does not reflect all cases, even cases that are fixated on integer performance.

I find it is mainly marketing that allows one CPU to outperform the other. If a said company does not focus on a universal code between AMD and Intel CPUs then we will always see a slower performing processor outperform what should be a faster CPU. Because of this I find it hard to truthfully compare processors on the market. Especially with the crap Intel indirectly? likes to pull.

I'm probably going get flamed, especially for going off-topic. But I dunno...

I don't think it's fair to compare CPU's across manufacturers either, especially when HT and different architectures come into play. I'd rather have people compare things like the P II 970/1090T together, and Nehalem/Sandy Bridge together. ESPECIALLY when all it starts is a flame war.

I hope you are referring to Cache rather than RAM in that 50% figure..

Yeah, that's what I meant by having more headroom. If Turbo can go that high on the 16 core part, there's a reasonable chance that the desktop variant has quite a bit of headroom for OC'ing outside of spec.

Nah, I meant memory bandwith. http://blogs.amd.com/work/2010/11/09/server-highlights-from-financial-analyst-day/

"Memory Throughput increase – We have talked about greater memory throughput for the newly redesigned memory controller, but today we put some numbers behind that statement. We are anticipating about a 50% increase in memory throughput with our new “Bulldozer” integrated memory controller. About 30% of that increase is from enhancements to the circuits and designs. The other 20% is from support of higher speed memory. I’ll leave memory speeds for launch, we need some secrets, right?"

Has new Architect which will be faster than the current market offerings BY AMD.. (They will not say anything about AMD vs Intel, they can't, legally.)

That's pretty much what most of us Techs know...

Everything else is purely rumors or speculation, more or less, unless you heard it from JT-AMD himself, go to the blog if you want real facts...

Personally I think I could be over hyping AMD's Zambezi, hoping it's much better than anyone can hope for, I just want something that beats Sandy Bridge, and BAD... I hope AMD wins here, regardless of how many shares the Enthusiast market presents in $ to AMD... Obviously AMD is sticking with what IS working for them, Servers...

It doesn't take rocket science to figure out that 8 real cores is going to be good, I don't care HOW you slice it or dice it...
(It may even be better than all the quad cores on the market, COULD BE, but we won't know YET..)

8 True Cores vs 4 Cores with Hyper Threading, you take an educated guess...
What I think, in multithreading will be 4 modules Zambezi better than i7 2600k (example x264, mostly in videoencoding, Cinebenchs, POV-RAy, 3DsMax -so rendering, science simulations etc). In single operations will be SB better (some photos editing, superpi :-D,Microsoft office aplications...) .
My tip for turbo? Hm, 500 MHz for all cores, for single modul up to +700 MHz. Clocks up to 3.5 GHz (without turbo).
OC stability think will be about 4.4-4.6 GHz.
Remember, its only my speculations and tips

i hope 16c parts will be similarly priced like today 12c.
this year i want upgrade to the highest possible in <900€ range "6268(6272)"

So... 6x4Ghz = 24Ghz. 32Ghz - 24Ghz = 8 Ghz. 8 Ghz / 24 Ghz = 1/3 which is 33.333%. So Zambezi will offer a 33.333% gain over the i7 950. As for the Gflops, i7 950 @ 4 Ghz gets about 65GFlops if I'm not mistaking so we'll see Zambezi hit 90Gflops obviously. I'm not sure about Passmark CPU cores, but something tells me it'll be 33.333% better. Unless... the 2cores in 1 design is seen as a single core, it'll be a totally different story. 4x4Ghz = 16Ghz Which is a Huge drop obviously.
Yes. This is totally BS.

8c*3,5GHz*4flops/cycle = 112GLOPS (IIRC, without AVX)

Just dropping in to note like many others have either directly or in more vague ways through lulzy trolling, this thread is pointless. Clock speeds mean nothing, they are a mere reference to compare between CPUs of the same architecture. There is a reason different CPUs scale better clock for clock. . THEY ARE DIFFERENT. Pentium 4s came out at very high clock speeds but that means nothing.

Go start a thread to add up Pentium 4 Ghz to find a estimate of how many it takes to go faster than an i7, this is the equivalent of that thread. Wait for benchmarks.
