New Windows 7 Bulldozer Patches Available.

Very quietly Microsoft has released two new patches available for the Bulldozer platform. According to the AMD blog these patches seem to offer little more then a 10% boost but the do improve over all performance. This is what Adam Kozak a product marketing manager at AMD had to say,

"Some of you may remember that AMD FX processors use a unique dual-core module architecture codenamed “Bulldozer”, which current versions of Windows® 7 were not specifically architected to utilize. In essence, for those with an AMD FX-8150 Processor, for example, Windows 7 sees the eight available cores and randomly assigns threads to them.

In initial testing of the upcoming Windows 8 operating system, we’ve seen performance improvements of up to 10% in some applications, when compared to Windows 7. This is because the system correctly recognizes the AMD FX processor architecture and cores. Thanks to close collaboration between Microsoft and AMD, Microsoft recently completed back-porting some of the Windows 8 scheduler code for AMD FX processors into a hotfix for Windows 7."

Here are the directions given by Adam Kozak,
So if you have an AMD FX processor, here’s what you can do to update your version of Windows 7:

1) Download the scheduler update (KB2645594) and install. This will tell the scheduler that your AMD FX processor contains dual-core modules (in fact this is similar to the SMT path that the other guys use). In essence, threads 1-4 now get assigned to their own module first.

2) Download the core parking scheduler update (KB2646060) and install. This will prevent Windows 7 shutting down unused cores prematurely when there are threads to be assigned (there’s a performance penalty parking and then un-parking a core).

The best possible cases for improvement are applications that use ½ cores in your AMD FX processor. In our testing using the AMD FX-8150 processor, we found the best improvement in wPrime, Left 4 Dead 2, and Lost Planet. Below you’ll find links to the patches:

I know one game it would choke on . Battlefield 3 ! That would kill the BD .. :twitch::wtf: They will need 4 patches for the 2 patch patch to get the patch to work on BF3 !
urrm actually Bulldozer outperforms the i-series in Battlefield 3. Thanks for spreading false AMD gossip.

Guys get over it..

Bulldozer a disappointment? Sure to some, not to others.
Is it outright a bad useless terrible chip? No, get a life.

10% from an OS patch?
Not too bad.

Glad to see this, hopefully they can draw a bit more out of it. I recently build a system with a fx8150, I can't say I was blown away by how incredibly slow it is.

Non the less nobody can argue it's not a step in the right direction that I think we can all be happy to see as losing AMD would put Intel in a position we don't want them in.

I would also like to bring into the light being this is NOT a true 8 core cpu...
Disabling Core Parking in windows for my i7 yielded much smoother game play in quite a few games when I left HT enabled, I haven't checked to see if this was an issue with the Bulldozers yet but if someone wants to give it a shot lets hear if it helps :)

Got the same 7.6% increase in cinebench single core as the leaked patch, this time with no hit to multicore performance : ]

Just wanted to chime in since I've had/have Agena, Thuban, Nehalem, Lynnfield, Sandy Bridge, and Bulldozer built rigs.

To all the people coming in this thread, bashing the Bulldozer architecture and its performance results,... go kick rocks. You're biased, ill-knowledge "advice" is unwanted and basically useless. There is nothing wrong with the Bulldozer platform, its not supposed to be an Intel killer. It is what it is; an alternative to Sandy Bridge with a different use in mind. Anyone who knows anything about the Bulldozer architecture knows what it's real intention was/is.

The moral of this patch release is, it's good to see Microsoft work with AMD to increase performance for a unique processor like Bulldozer. It's nice to see a software giant like Microsoft with with AMD to increase performance, especially when it helps improve upon performance of Bulldozer. Win/Win.

You Intel fan boys need to build multiple bridges, and when you're done complaining as you build, you'll eventually get over it.

Fact is, all of you Intel fans want a AMD 7970 for your precious Intel rig. There's no denying that.
So... another moral, learn to appreciate (and respect) all brands and what they produce, unless you want to pay $500 for a low grade CPU from Intel down the road.

Here is a comparison.
So it's just dissapointing.
Those people are idiots, wasted a bunch of time benching multi-core stuff, it's not designed to improve it! :laugh:

I'm not a dissapointed AMD-User.
Performance of my Sys is still fine. It's just the kind of AMD is dealing with the situation, makes me angry. Bulldozer is what it is. They should never praised it as an eight core CPU.
And the hole FX-rebirth thing just wakes expectations, they could never satisfy. And they knew that. And teasing with patches, which should deliver up to 10% performance increase doesn't help either. Cause as the results here show clearly none increase. Except Resident Evil. But who plays only Resident Evil.

The patch does not provide 10% improvement in everything. It provides 10% improve in low thread count programs (aka running only 1 or 2 threads). The test results on your post is BS because he tested 8 threads and 4 threads which are both NOT what the patches are improving. The results in those guys test is mutt, pointless, serve no purpose, doesn't test what was improved, etc. etc.

something strange happened to me after the patches.
i have a 965be oc to 3.9g.
no change just using windows index bs (still 7.5).
but my ssd went from 7.7 to 7.9.
just thought i would pass this along

and now another odd thing.
i limited my oc to 3.9g because of temp (air).
before the patch, using prime95, i got as high as 60c.
now im at 52c.
only been running for 1/2 hour, but if it holds, i think i will tweak to cpu again.
maybe my idea of using amd chipset, amd gpu and amd processor wasnt so lame after all.

Windows CPU score went from 7.4 to 7.5... for free :)
by: trickson
WOW a .1% increase ! Now you can play Crysis ;)
0.1 / 7.4 = 0.0135 * 100 = 1.35% increase. Learn to do some basic math before your next bout of "posting diarrhea"....

And for the record, I don't give a rat's ass what processor you have: you use whatever you need to get the job done. All this "my processor is better that your processor" crap is just so much forum wanking.

damn.
after a hour it went up to 54c.
time to tweak the cpu.

Stay on topic, behave, post in a civil and respectable manner. If some of you cannot do this, I will be happy to hand out more infractions/warnings.


Thank you.

no prob here son of trick.
what im using now was going to be intel, but 130 for cpu, 130 board, 130 for ssd, allowed me to splurge on the case and memory.
and if amd sorts out their latest and greatest, my board has the bios for bd.
maybe with microsquirts efforts i will get 2 extra years from this latest build.
who knows.

maybe this patch improves/hoses non-amd.
i have a i5 laptop with intel gpu.
i rairley use it and have nothing i cant loose on it.
other than the time to re-set it up.
i smell experiments.
in 24 hrs i may know a little more.
but right now the wife sez go to bed.
and i think shes right this time.

The FX-8150 is not a bad product. It is a new design and it has some quirks. Glad to see they are working to resolve these quirks.

I hope these updates the task scheduler fixes the issue I have with Deus Ex.
Not to pick on you as I just started to read this thread. The 8150 is a piece of shit cpu, heck the whole FX line up is a joke that shouldn't have even been launched to the public till they got it working as expected. I owned one, tested it, sold it and never looked back thank god! My 1090T stomped the shit outta the FX @ stock speed. The fx only pulled ahead of the stock X6 around 4.7-4.8ish GHz..and sucked wattage as a cheap whore would suck! These Quirks are more then just that, and I pity anybody that owns one of these chips and think a MS patch is magically going to turn it into a monster... In toll it really is a monster... A fucking wattage monster that needs to be but outa it's misery and redone period! FX guys stop fooling your selfes, these chips are junk and sorry to sound harsh but its the reality. I was a long term AMD fan boy for some time, but not any more.

I suspect After Piledriver is launched the Intial FX Lineup will be phased out.

All i can really say is be careful 1155 users, you may very well be on borrowed time like 1366/1156 users...

eidairaman1 delete my post please as I noted why I deleted it... and the 1155 owners are to fear what Pile driver? I highly doubt that. Didnt amd say the PD was going to be 10% faster then BD? Im sure I seen it some where in here.



GG AMD! hope that 10% translates into something better.

Um.. You're free to post your opinion, I and other members were getting sick of one individual spamming this thread with uninteligent, belligerent fanboy talk and turning this thread into their own personal circus.. It's not needed, TPU is better than that. You're post is acceptable.

Thanks Erocker, I was just covering my ass. Look what happened to aussi man Mussles after going to the ATI-AMD site a while back and getting banned over a honest question with an answer, BANNED!!!
Cheers to the staff at TPU :toast:

EDIT: @Static~Charge
Trickson is just that a trickster, no different then Mailman (#1 Troller at times lol jk). It's all fun and good reading. Cut the man some slack as he's a good guy ;)

I wasnt talkin about Piledriver doing any damage, just the forced upgrades which left 1366/1156 users without any CPU upgrades.

Sorry If I confused you...

i would say when bd gets cheap, beware of used chips.
but there will be a batch that "should" ROCK, when new and not abused.
my board may not be much good past the next revisions of fx, but if i pay attension to tpu and other class sites, some smart azz is going to nail down the right lot numbers.
damn wife.
batteries are low.
gotta go
:)
