[BSN] Microsoft Releases AMD Bulldozer Patch by Mistake: Incomplete Update - Page 3

That was the whole point of the patch anyways. It loads 1 core per module first before loading up the full module. That decreases resource sharing and increases single threaded performance slightly.
It obviously didn't reflect this across the board, so the patch was pulled.

My beef with said poster was that he was claiming a 20 FPS increase.. on an Eyefinity 3 x 1080p setup.. with Crossfire 6790s. And no, that's not a typo. 6790s. BF3 is a hugely GPU bound game, and with such weak GPUs and such an enormous resolution, don't you agree it's more than a little far fetched?

Also, I'm aware of what the patch was -supposed- to do.
Why upgrade?

AMD had a driver for dual core CPUs back in the Athlon X2 days.

I'm bewildered that this takes more than a few weeks to code and do QA for, and I'm also bewildered that AMD didn't work with microsoft to get this done before release.

Not quite..... If you have two related integer threads, you want them on the same module. If you have a integer and a floating point thread, you rather have them on different modules.

Hyperthreading duplicates the pipelines before the ALU/FPUs. This allows Intel CPUs to keep the pipeline more filled with mixed loads.
301


Bulldozer duplicates the ALUs themselves. This allows AMDs to process more common integer threads.
318


QA of this type of code probably takes months. They are changing how the thread manager behaves for tens/hundreds of million PCs. The threading logic can be relatively complex and you always have to worry about those weird scenarios.
Once again...

AFAIK the main "trouble" AMD is having with the new FX processors is the fact that they are selling faster than they can make them.

...that is because yields are too low. tongue.gif

Both Bulldozer and Llano yields are low so it is not a demand issue... but a supply issue!

Supposedly, Apple was looking at Llano for their MacBook Air but AMD could not supply enough chips.

If they were not selling, yield would be irrelevant. What part of "FX processors are selling faster than they can make them" confuses you?

I am not flaming you so please don't take offense; What is your native language? It doesn't look to be English.
Where did you get this information?

No idea and if it need, it still might need one lol.

Well, just because i say it is bad when your CPU needs a patch, it does not mean i am automatically directing it at AMD. Also, if you wanna get down to it, at least Intel recalled a bad product.
