AMD Zambezi news, info, fans !

[FlawleZ]

You have seen "it". The vrzone and now coolaler posted same results. "This" means slower than Thuban or barely matching Thuban. And I use 8150 for comparison,not 8120. Granted there are some cases where 8150 with this level of performance will still probably spank 1100T,but nothing like the projections from December last year showed. Where is the double-sized SMT capable FlexFP performance? Where is the HPC improvement that is quoted for server parts gone? Remember we are left to think that even in legacy code server parts will be ~50% faster with same clocks as previous MC cores. This equates to around 10% better per core performance in SIMD workloads. All Zambezi leaks thus far show no such thing . On the contrary they show very poor performance of this "powerful double-sized FPU".

I don't understand why you're still trying to draw a rational conclusion from yet again "just another leaked benchmark." The results are all over the place in terms of performance within the last 6 months. I thought we had decided that it makes the most sense to take these things with a giant bowl of salt until we have official results once the NDA is lifted?

Well you probably read it,but this level of performance is in reviewers guide(I hope you know what that is). 9 months ago, in some docs 8C Zambezi at 3.5-4Ghz was shown as 70% faster than 1100T. There is your discrepancy. Now 1100T is actually looking better from price/perf. POV.

Can you explain why CB would report 8120 and CPU-Z would report 8130? I don't think these benchmarks are legitimate.

CB is reading the "Specification" string wich is the same in CPU-z, not the "Name". I think "Name" in CPU-z is gathered from a Database, and "Specification" is read from the CPU itself.

What's 'reviewers guide'? If you're telling us that coolaler is something special, why they even have no NDA in hand.(NDA is not lifted)

Have you seen Radeon 6870/69xx launch slides? The performance comparisons(versus competing products from competitors and their own previous gen products),uarchitecture details,pricing strategy ,all made by manufacturer and sent to press as briefing material and guide for their own review .

And no,coolaler is nothing "special". Nor is vrzone for that matter. I'm just telling you that the level 8120 is showing in the leaks is close to what it will be showing when it launches. And this level is pretty dismal ,at least compared to all marketing talk we had and previous projections(by AMD themselves) that showed MUCH higher performance.
Bulldozer is supposed to be "multithreaded beast" . In benchmarks that utilize all the threads(or cores if you like),like cinebench for example,there is no sign of the beast. It's tamed. The "double-sized"(compared to K10) and "very-powerful" 256bit FPU ,even in single thread workload such as Cinebench10's single core test mode,is failing against Thuban's one core. It has even higher Turbo on its disposal in that case...

I've forgot them.

BTW it seems, that you have something in common with those guys who satirized AMD running a platform with slides instead of a CPU.

Well you need to refresh your memory. Zambezi is launching soon.
And no,I don't have anything in common with those guys. I'm just being a realist now,not an optimist who based his expectations on power point bullets.

I found a few posts by JF which you might find interesting, I think he was commenting the sandra benchmarks:








These are from [H] and were posted in august, but there are quite a few hints there.

I think everyone should relax, there are so many fake benchmarks flying around no one can tell which one (if any) is true.

We do however know that IPC increases and clock is increased shouldn't that result in better performance?

Actually those sisoft numbers are quite good in SIMD department and not THAT bad in integer part,IF Turbo was off. If Turbo was on,then integer is abysmal (compared to Family 10h) and SIMD is still good. All this on "unoptimized" platform.And all this if the test is even real.

No I needn't. Empiricism means nothing to me, history was history.

There's a word that better than realist and optimist - neutral, and you could post less. And I will post less, everybody should post less.

These days I'd love to silent myself but often couldn't bear some weird comments flying around my ears and eyes. I'm tired.

I dont buy AMD giving any material to reviewers until its ~week to launch. That is based on what Sampsa said about it.

Then my guess would be that they got material 12th and launch indeed is 19th.
