I've been following the bulldozer thread for weeks hoping to learn whether my next system will be sandy bridge based or bulldozer based. I finally found this benchmark this morning and thought I would share.

http://wccftech.com/2011/05/10/gigabyte-leaks-amd-bulldozer-details/

In summary it says:
The CPU “AMD FX 8110″ has a core clock of 2.8Ghz as seen from the windows experience index however CPU-z shows its running at 3.8Ghz which is because of the AMD’s Turbo boost technology, The socket supported by the chip is Socket AMD3b 942 and has a maximum TDP of 95W. The CPU consists of 8 cores and 8 threads, 8MB of L3 Cache and an Unlocked Core. Instructions supported are seen in the CPU-z tab.
The two benchmarks running in the background are Wprime v2.04 which records a score of 5.516 sec (32M) 166.895 sec (1024M) and Super PI score of 7.8 sec (1M calculations) 7 min 22 sec (32M calculations). The motherboard being used is from Gigabyte with model name GA-990FX-UD5.

The benchmark is apparently fake, and in the meantime this thread has greatly outlived its usefulness.

That has to be fake.

Those SuperPi scores would make it a lot faster than SB in single threaded performance, and I don't believe that will be the case.

I saw this at another forum and I am quite suspicious. Check out that IM window, looks like a joke. However, if this is real, it's very, very interesting, AMD might be giving intel a run for their money with this one. The wait is making me insane.

Quite strange that SB is believed good at single thread apps..
Ho, it s about INTEGER based single threaded perfs, isn t it...

Super pi rely mainly in FPUs, and in that matter , BD single
thread will undoubtly be devastating for SB as well as for
the "single thread is the most important" afficionados..

I guess that once BD show its capabilities in that domain,
the single thread perf as a cornerstone will suddenly vanish..:)

If this is fake it seems like somebody put a lot of work into it. Maybe it is, I don't know. Since Intel's Z68 is to be "officially" released tomorrow I wonder if these leaks might be intentional by AMD to steal some of Intel's thunder. I know I have been frustrated with the lack of BD information and was leaning towards buying a Z68 board because I was sick of waiting. If these BD benchmarks are real I may try to hold out to see what the pricing is going to be.

I dont think you can go wrong waiting no matter what. Its only a few weeks. If BD doesnt deliver, then there's always SB with proven performance. I myself am getting itchy to upgrade my i5-750 but Im holding out to see if Bulldozer might actually bring the goods.

Gigabyte contacted the rumor site to say that all the details in that shot are fake.

I can't wait for the benchmarks, but I expect BD performance to land somewhere around the i7 920 in terms of gaming. As to heavy, multi-threaded apps, I think it will be surprisingly close to the i7 2600k.

Sorry if it is a fake. I can't fathom why somebody would bother putting that much time into creating fake benchmarks. Must be bored I guess.

I think I'm probably just going to go Z68. I don't play any games on my pc, I just need it for editing and rendering video. My E8400 getting pretty tired at this point and I have a feeling if AMD really did have something to rival Sandy Bridge they would have at least put SOMETHING out there. If the official release is tomorrow (Z68) I wonder when motherboards will be available at NewEgg. That will ultimately be my deadline to waiting on Bulldozer. If I could order a Z68 board today I would just do it and be done with it. Sorry AMD, I really wanted to to come back...

There was a tremendous amount of fake graphs/pictures surrounding Cayman gpu launch. Sadly its not hard for many amateur photo-shop users.

I'll be interested when I see a real application being tested, in either a controlled comparison, or with repeatable methods (FI, making a WAV from a FLAC on archive.org, and encoding it in a few different formats, would be a nice easy test, that could give a hint towards performance in real apps).

Even if it were real, synthetic benchmarks are only good for making sure nothing is wrong with your hardware and software, not for comparing performance in any useful way.

By looking at the picture it looks almost legit till I see that the image had a few mistakes.
1. This was taken on the 29th April with a FX-8110 branding at CPU-Z but another leaked image showing Cinebench on the 7th May was showing it was still an ES.
2. CPU-Z showing that the FX-8110 has 95W TDP which I don't think that is very likely.
3. I don't see any running applications that would make it run at it's Turbo frequency.

Somehow I have a feeling that this isn't even going to be close to reality.

According to AMD , the FPUs will see a dramatic improvement,
since they claim 50% better perf/core .

This should be even better on an FPU intensive single threaded app.

It would have to be.

On a per clock basis, those SuperPi scores are more than 100% faster than Phenom II.

Can't remember a jump that big ever happening, but I suppose it's possible.

What is your definition of FPU intensive?

Please name an application that meets that definition.


Renderings , most simulators and conception tools , photos editing
and generaly whenever continous functions are used for modelisations..

AMD said that BD FPUs have four times better perfs than in K10
and that s why they only put 4 of them with 8 INTEGER units..

That s consistent for up to 100% better perf compared with K10
on a single treaded FPUs sensitive application , which is surely
the case of Super Pi since it s a quite simple soft...

Okay, then we will see how those perform. Even though the apps you just listed are mostly integer.

No, 4 times compared to K8.

K8 - 64-bit FPU
K10/Greyhound - 128-bit FPU
Bulldozer - 2x128-bit FPU

That says nothing about IPC, obviously FPU performance is determined by more than width, but each integer core in BD has a 128-bit FPU attached. It's just it can also use the other core's FPU as well if that's idle and it's needed.

FPU performance should at worst be the same as Greyhound.
