I'm still not a PCMark05 guy, but I had an SSD to test so I started playing a little and the info in this thread has helped some of my scores quite a lot :)

 

Thankyou!

I don't have direct comparison with more than 4 cores with exact the same settings.

Just found PCMark04 results with FX-4100 @ 6918 MHz and FX-8120 @ 6782 MHz:

4-core: 49.3 web page rendering, 317 fps WMV - http://hwbot.org/submission/2231053_

8-core: 55.2 web page rendering, 362 fps WMV - http://hwbot.org/submission/2240067_

Don't look at Overall score, FX-4100 result was done with wrong Grammar Check.

 

Windows was updated with AMD Bulldozer Performance Updates:

Windows6.1-KB2592546-x64.msu

Windows6.1-KB2645594-x64.msu

Windows6.1-KB2646060-v3-x64.msu

 

 

Do you use WMV settings suggested in PCMark05 Tweaking Thread?

I mean this: "Force NumThreads"=dword:00000002

Try playing with other values ;)

 

Thanks.

 

I did set the registry value for the number of threads on fx-8120.

 

This was hard set to 8 threads (just look at audio/video):

http://hwbot.org/submission/2259791_i.m.o.g._pcmark_2005_fx_8120_42727_marks

 

The 8 threaded score was better, but I believe that was the result of Vista over Win7 and I was running higher clocks on the 8 threaded submission (I spent more time on it, and higher clocks were easier on that motherboard). That isn't a good comparison because many settings as well as the OS was different.

 

I don't personally have any direct comparisons with similar settings either, but from running the bench a few dozen times on the fx-8120, it seemed to me that scaling stopped more or less at 4 cores.

 

That said, I don't believe the encoder actually supports splitting out more than 4 threads (reference here: http://www.microsoft.com/windows/windowsmedia/howto/articles/codecadvancedsettings.aspx - that isn't talking about wmencoder9, but even a newer version). Seeing as how it is doing a video and audio encode at the same time though, I suppose the video encode should be able to use 4 threads itself, and perhaps the audio can use several of its own... I don't know.

 

Looking at scores however, the best 2600k scores are done with only 4 cores active and no HT. This tells me that its likely scaling stops at beyond 4 cores again.

 

Not sure, just my inferences from my own benching and looking around.

its funny how time changes things, 18-24 months ago most of these were considered cheats,

 

now its all gravy,

 

im very happy that this benchmark is progressing..

 

a tweak applied by one man is a cheat, a cheat applied by everyone is a tweak

If only one man knows the trick and it seems to good to be true, then the correct way of dealing with it is to assume it is what it looks like - something that fucks up the benchmark.

On this topic, pro you had posted results on XS of replacing the browser. Scores of 60+ and 100+ on web page rendering. You never submitted to hwbot, as you knew it wasn't hwbot legal... but just out of curiousity, I tried to do browser replacement stuff to understand how you got those scores. I was never able to replace/rename iexplore.exe and get another browser to actually run the test. Any tips so others can understand how that was done?

Posted (edited)
you dont need to replace web browser for 100+ pages/sec, ie9 is more than capable of it

 

Are you saying you've done it? I haven't seen any results or discussion anywhere about it.

 

When you did 60, you said you were using a different browser:

http://www.xtremesystems.org/forums/showthread.php?240156-PCMARK05-testing&p=4135651&viewfull=1#post4135651

 

You didn't say anything when you did 110 on web page rendering a few days after that:

http://www.xtremesystems.org/forums/showthread.php?240582-AMD-claims-a-global&p=4144958&viewfull=1#post4144958

 

Only one person doing 60+ on hwbot currently in web page rendering:

http://hwbot.org/submission/2218295_mtech_pcmark_2005_core_i7_2600k_50458_marks

 

Several people around 50+, which these tweak will do on Sandybridge:

Not saying you are wrong, and not challenging you. Your comment was vague, looking to understand.

can be done with a different browser or as ive recently worked out can be done with ie9 also

Thanks to Christian Ney for create the thread and all the guys for sharing the tweaks and secrets, I did some quick test the last weekend and I had a jump of ~9k points.

 

I was 100% sure that you can't disable cores until Massman confirmed me that you can do it but still competing in the same category of your CPU with all cores actives. Maybe I try again this, I'm just ~4k away from the 1st place in the rank of my CPU.

 

Thanks again guys ;)

But for PCMark more cores are better, so don´t disable it!

I have a six core, until I read, the benchmark scales good until 4 cores.

 

Yes but someone pointed some post ago that some subtest scales with extra cores. Try it and let us know, please.

As soon as I assembly the rig again, I will test that and post results.

Does the Bob tweak work every time for you guys? I sat all night yesterday and it took me around 40-50 trys before it worked, am I missing something or is it just my crappy old OS thats bugging? I'm going to do reinstall but I thought I would test some tweaks on the old OS first. :D

Posted

^^ it works for me 99% of the time, occassionally it doesn't but that is the exception. - what OS? I can comfirm Bob's tweak works in both W7x64 and vistax64. I think Bob said it does not work in W8.

Not the best place to ask.... but i'm gonna go for it anyway :D

 

I've been kicking my Celeron 352 around in PCM05 and it looks *alright* EXCEPT.... for MT Test 2- Image decompression. The score is in the toilet. Sometimes it looks like it's failed, but I get a score.... a really bad one (<2 MPixels/s)

 

Any ideas? :)

Posted

k404, its been a few weeks since I ran PCM05, is MTT2 the one that does text/uses fmpad?

 

If so, you can go to properties of FMPad and set it to disable themes when it runs... See if that fixes the lousy score on that test.

Posted (edited)

Yea, the other part of the test is text edit :) Compatability -> Disable visual themes. Will try that first and see what happens :)

 

My other PCM05 scores have normal MT Test 2 numbers, maybe it's an architecture thing, just needs rubbed a slightly different way :)
