UPDATE: Microsoft has pulled down the patch as it had been released prematurely.
Microsoft Corp. on Thursday released a patch for its Windows 7 and Windows Server 2008 R2 operating systems that boosts multi-threading performance of systems powered by the latest microprocessors from Advanced Micro Devices which rely on Bulldozer micro-architecture, such as FX chips for desktops and Opteron processors for servers.
Currently, performance of AMD central processing units based on Bulldozer micro-architecture (FX, Opteron 4200-, 6200-series) under Windows 7 and Windows Server 8 R2 is slower than expected because the threading logic in the operating system is not optimized to use the simultaneous multithreading (SMT) scheduling feature of AMD Bulldozer processors. The update optimizes the performance of AMD's latest CPUs that power Windows 7-based or Windows Server 2008 R2-based computers.

Exact performance advantage that the patch brings to systems featuring AMD Bulldozer microprocessors is unclear. What is know is that only programs that rely on execution of multiple threads at the same time will benefit from the hotfix, therefore productivity programs are unlikely to get a boost, whereas demanding applications like data processing, rendering or simulations will run faster.
Only performance benchmarks will tell whether AMD FX-series microprocessors for desktops will be able to outperform Intel Corp.'s Core i-series "Sandy Bridge" microprocessors in a large amount of applications due to the patch for Windows 7.

Earlier this year AMD issued a document claiming that with next-generation Windows 8 scheduler its eight-core microprocessors will receive 2% - 10% performance boost over what was demonstrated by Windows 7.

So, its like trying to polish a turd, right AMD?

I have to agree with you on that one. AMD is going to fail with x86 APUs. I don't hate AMD but without them it would be Intel vs ARM and all of the companies that make CPU's with ARM architecture.

I'd have to disagree with you on the APU front. To be honest, I think their APU's is AMD's best bet on gaining ground in the mobile market and trying to hold onto whatever they have right now for desktops.
If they don't royally screw up their upcoming APUs with the Piledriver core couples with their new graphics architecture, I think the line-up should do fine.
But I still maintain, as others, that Bulldozer was garbage as it couldn't outperform Thuban in some benches and lost in some is really pathetic. The latest hotfix is just some really bad polish on a steaming pile of crap.

arm doesn't make x86 processors and ARM ones don't pack enough power
and from your comments you seem to hate AMD
and APUs are really sucessful
if AMD fails it'll be intel vs VIA because Intel would halt improvements untill VIA catches up which would take ages

Where did I even mention ARM in my comment? And now that you mention it, I do see ARM having a very bright future in mobile, as well in the desktop and server space. You got nVidia working on Project Denver to create a high-performance CPU and HP (currently number 1 with servers in terms of sales) working with ARM CPUs for its servers from its Project Moonshot.
Samsung recently told the press that they sold over 300 million mobile phones, running ARM.
Oh and, Microsoft will also have support for ARM with Windows 8. Do you know why x86 won out all those years ago? Because Intel and Microsoft got cozy in the bed together.
And now, Microsoft seems to do the same with ARM and it its going to shake the market.
Mind you, x86 is old and bloated. One of the reasons why the infallible Intel couldn't get x86 into mobile phones yet is because their own ISA is old and bloated and they are spending millions or even billions on R&D to get it small enough for mobile phones. But ARM is already gaining so much momentum, Intel is going to have a very hard time trying to convince companies to use x86 chip in a mobile phone platform.
I guess what I am trying to say is that ARM is going to be the future. Is it going to completely replace x86? No, it won't anytime soon as too many computers and applications rely on it. But does that hinder ARM holdings? No, it doesn't because they got their ARM architecture that is so successful and they don't need to make x86 CPUs and they can only go up it terms of performance/watt as time goes on.
Do I hate AMD? No, I don't. I just call it how I see it and AMD fumbled bad on the Bulldozer architecture. You had JF_AMD spamming up forums saying how IPC increases and yet you have benchmarks telling you otherwise. You had marketing from AMD (glad they were fired) saying how awesome the FX-8150 would because of the "8 cores!!!! means better performance!!!!". Well, Xbit's own testing says otherwise and at the same time, soiling a brand that was once great. Remember the Athlon FX-51? FX meant the domination of Intel products back then. Now, its a really crappy joke in tech communities and that is pathetic.
I happen to have some products from AMD, an HD 4870 and my good 'ole Athlon XP 2000+. I if I really hated AMD, I wouldn't have bought those products. I concern myself with who has the best performance/dollar for ME, regardless of brand.
But right now, if I were to build a new rig, I'd avoid AMD simply because their CPUs don't have the performance/dollar like Intel's CPUs. Did you read Xbit's newest review on the more recent FX CPUs? They mentioned that they are way over prices for the low performance they offer compared to the Core i5 and Core i3.
But I would still buy their GPUs as I am a very happy camper with my HD 4870. They've done very will with the HD 5000s, HD 6000s, and they look to do well with the HD 7000s.
And you mention Intel vs VIA? That's like a black hole vs ping pong ball.

You have a x86 versus ARM paradigm. It will be possible in the near future to execute the two processors' instruction sets simultaneously. It will be possible to create a CPU combining the cores of both. And guess who is going to be the only one who gets the licenses to do that? (hint - it won't be Intel). Can't wait to see how it benefits portable computing and to see my shares quintuple.

Rory Read did open the door to the possbility that AMD might conjure up something with ARM according to some carefully chosen words from TechReport's article on it.
I'd love to see AMD do something great with the ARM architecutre and couple it with their graphics know how.
And putting x86 and ARM together, I don't think it would be impossible but I don't know enough about CPU architecture to see how it can be done.

There are rumors that Microsoft has already withdrawn this patch due to its, hmm..., unusefulness.

that's a good news. We'll see if SB also get improvement from Microsoft (BD) patch.

The patch is incomplete on its own since it belongs to a set of patches and accelerates both AMDs FX processors and Intels Core i7's.

if MS do not release it, Y NOT let AMD release it as hardware driver instead of a patch for everyone?
