AMD FX 8150 with Microsoft KB2592546 Put Through 'Before and After' Patch Tests
To the surprise of many, last week, Microsoft rolled out a patch (KB2592546) for Windows that it claimed would improve performance of systems running AMD processors based on the "Bulldozer" architecture. The patch works by making the OS aware of the way Bulldozer cores are structured, so it could effectively make use of the parallelism at its disposal. Sadly, a couple of days later, it pulled that patch. Meanwhile, SweClockers got enough time to do a "before and after" performance test of the AMD FX-8150 processor, using this patch.
The results of SweClockers' tests are tabled below. "tidigare" is before, "nytt" is after, and "skillnad" is change. The reviewer put the chip through a wide range of tests, including synthetic CPU-intensive tests (both single and multi-threaded), and real-world gaming performance tests. The results are less than impressive. Perhaps, that's why the patch was redacted.

Actually, that the results are mixed and not consistent shows that there is something funky with the architecture. If they were using affinity to keep the code over two neighbour cores whereever possible to get the Turbo-Boost effect to come in, then why would the results sometimes be worse? I assume that the flipside to the turbo boost is the effect of smaller L1 cache and the neighboring cores having to share cache and pipeline rather than letting two cores and their caches work independently. Swings and roundabouts.
I think the "affinity to get Turbo boost" feature ends up being a mistaken performance tweak. It is also a worthless concept if the next iteration of BD has higher overall clocks and lower Turbo boost.
Poor AMD. Hyping scheduler changes being the solution to all their woes... when it wasnt.
Sounds a bit like the wife... "if, but, you, not my fault..." yadda yadda

In reality though, the quad would trump that dual in BF and such. But they need more per-clock performance. A bit too late now...
I'll be surprised if the actual patch brings a performance increase, but let's at least wait and see if it does.
That is 1 benchmark on 1 website. The other ARMA 2 benchmarks from "other" sites are not that poor. Common sense can see that is merely a freakishly bizarre result maybe due to a driver or bad configuration which probably has nothing to do with Bulldozer.
a bad product
But I'm saying that ONLY Hard OCP shows ARMA 2 performing a min of 9 FPS - which anyone with common sense can see is unrelated to the CPU. A fucking Athlon X2 from 2006 can get higher mins than 9 FPS. So common sense will say it's an outside influence. Software/configuration/bios etc.
For all we know it could of been driver conflict with the Nvidia card tested.
thats all i can say
dont ask me to because im on 8+ year old hardware running win 7 32bit.
besides is the 2700K truly superior to the 2600K or 2500K other than just a model number change? I noticed Intel is to release a 2550K or 2650K shortly...
Compare ARMA 2's with Bulldozer result to any other hardware website and you won't see a min of 9FPS.
What I'm saying is the ARMA 2 test is probably a bad run, influenced by a third party factor. eg. You can run 3D Mark 1,000 times eventually a driver, bad cofiguration or some weird fault within Windows will have the result coming up short atleast a few times.
www.eteknix.com/reviews/processors/intel-core-i7-2700k-flagship-showdown-review/3/ No, I'm not. You don't understand what "trolling" is. I'm being pushy, not trolling. If I'm being flat out rude, then it'd at best be my arrogance, but not trolling. I actually have been reading here far longer than your join date, so no need to belittle me. As for my Intel e-peen, sorry, not going to bother.
Why do you think I called him a fanboy? Get some reading comprehension.
They say ignorance is bliss so you must be a very jovial person in real life.
Anyway, I'm done dragging myself down to your level to grunt in your language. Have fun.
Now Mr "I post facts" where does Intel Vs BD come into play in this thread? so yes, you are trolling, posting off topic benches for what reason? then you go shouting fanboy, do me a favour, there's only one fanboy in this thread. Your posts have been reported, I suggest you wind it in unless you want to end up banned here like you have been from the EVGA forums and god knows where else.
I guess you got it because of the higher stock clock which means not having to overclock it as far- to extent.
Im wondering if your P67 is holding your Model back vs the Z68 Series.
So How much did you drop on it vs a 2600K if I may ask?
