[TH] Windows 8: Does AMD's Bulldozer Architecture Benefit? - Page 3

Lol, no one blamed windows 7 unless they are retarded. If anyone, including yourself thought this was the case then they should severely re-evaluate their knowledge base before posting.

FMA, AVX and XOP instruction greatly increase the throughput of the module design, without them you're left with shoehorning batch decode. Right now theres a big holdback with thread staging and execution resource utilization. If anyone thought a refresh of an operating system and a scheduler update were going to alter Intel x86, then they are severely mistaken.

Where were you when Bulldozer came out? So many FX owners (on OCN and other forums) were blaming Win7 on hindering the performance of BD CPUs.

This article addresses that assumption and puts it to rest. Nothing more, nothing less.

Thank god I didnt upgrade my 8120 BD to a PD. Picked up a i3570k and asus sabertooth Z77 mobo on last Saturday. I thank god and Micro Center for $169.95 i5 and $50.00 off on any z77 mobo so purchased a sabertooth for 189.95.

Just because FX fails in Cinebench single thread benchmark doesn't mean that it would always perform lower. Cinebench depends on the FPU performance and a single core of FX can only utilize the half of 256 Bit FPU because of shared FPU unit between both cores in a Piledriver module. And when its about multithread FX wins because of it now uses all four 256 Bit FPU, and then because of its higher clock rate FX wins over i5.

AND as I've stated above that "Just because FX fails in Cinebench single thread benchmark doesn't mean that it would always perform lower in single thread" I believe is true because most real world single thread programs don't expect much from FPU. They can perform at its optimum speed by CPU's higher Integer Bandwidth. And most you should know FX's each core has two Integer pipeline while i5 has ONLY ONE. Clearly FX has massive integer bandwidth than i5 and some i7 and indeed FX wins in most Integer test benchmark. This proves FX may be even feel faster in most single thread apps (especially those which hasn't been designed to use Floating Point Unit)...<< This is what people don't understand.

And even if Windows explorer and Internet browsers are single thread, they can perform more quickly with FX because of FX's Dual Integer Pipeline per Core, obviously FX can handle more threads per core than an i5. They will feel equal or may be faster than i5, Also you can not forget Internet browsers can now use GPU for 2D/3D workload. AND I BELIEVE FX WILL REALLY FEEL FASTER.

So you spent about $390 including tax for a marginal at best replacement?
8320 would have been more cost effective.

Then I have zero reason to upgrade to 8 then. Huzzah!

Not really. I ran 2x 6950 crossfire with Asus CHV so the side grade does help a lot. Haven't overclocked the i5 yet and I ran my 8120 at 4.7 but I do notice the difference. Just runs snappier and smoother.

Why would he throw more money into a hole? The difference between a 8120 -> 8320 is much less than a 8120 -> 3570k

AMD pointed out that Windows was not optimized for the module-style architecture. Not specifically Bulldozer. But Bulldozer obviously did not work out the way it was intended (AMD would never admit that though). Like so many have correctly pointed out: Piledriver is what Bulldozer was supposed to be. So the fact that Bulldozer was not able to capitalize on software optimizations is completely irrelevant now that Piledriver is out.

Also, remember the first patches MS released for Bulldozer? If I recall correctly, the first patches actually did improve performance 5-10%, but they caused crashes all the time. So MS pulled the patches and re-released them. The new versions only improved performance 1-2%. It seems they still haven't fixed the problems of the original patches and are still working with the updated ones that just don't go as fast.

So they BOTH failed. And so did TH for not testing with PD. We're living in a world of FAIL.

amd never fails to dissapoint
