Intel Q9450 vs Phenom 9850 - ATI HD3870 X2

[Boschwanza]

I have done the CoH test again recording the utilization with everest.

Phenom 2.5 GHz / ATI 1950Pro / 2 Gigabyte Ram @ 1000 MHz



So resolution changes about nothing in terms of CPU utilization at least for CoHOF. I think the small differences are within measurement tolerances. I will try Call of Duty next.

Call of Duty 4

I have choosen the Mission where are you heading to the ship in the ocean b/c its very script based.



Call of Duty acts like Jack says, cpu utilization decreases while resolution goes up. There is something odd, during the intro sequence to the mission at 640*480 there is almost no utilization (7%) if you turn to 1280*1024 this suddenly turns to about 25 % i re run this test a couple of times giving me exact the same results in every run.

World in Conflict Next

This is quite interesting, during the atomic bomb attack and the bomber raid the CPU Utilization is increasing .

Edit:

Just played around a bit with WiC comparing "very high" settings with 1280*1024 and 800*600



Well, its hard to draw an exact conclusion. During the bomber incoming i gained the most fps in 800*600 in comparision to 1280*1024, so in this particular case, Jack is right. But when the real action starts (atomic bomb & bombing raid) somehow the utilization increases so there has to be more calculation or whatever. I gotta think about this "issue". So far good night

First, and foremost, thanks for taking the time to do this... data is always, always welcome ....

Yeah, there are cases in your runs where it is evident. At these lower resolutions, it is harder to see any effects... though the 1950 should throttle more than what I suspect...

I will repeat the very gross extremes I did with the 4870 X2 on the phenom and publish those as well.

Hey -- how are you benching COD4?

EDIT: Also, I just tested WIC -- and getting interesting results -- on CPU utilization. Did you use presets to set the high vs low?

Is smoke etc done with vertex data?
If some type of graphics has some sort of knowledge on the resolution it could be that the processor needs to calculate more on higher resolutions. Don't know this, just one speculation

Yes, volumetric smoke gets vertexes, shaded, and made translucent just like any other 3D object.

Download the Toy Shop demo, and run at different resolutions and look at the smoke generated from the chimney's, press W to see the wire frame ... the number of vertexes does not change... this is fixed by the 3D model framework. At least this is what I have been able to gather in my reading.

http://developer.download.nvidia.com...gems3_ch30.pdf some interesting details.

EDIT: Here is a very interesting one: http://www.iam.unibe.ch/publikatione...le/at_download discussing 'threading' fluid simulations for 3D rendering... the work load here is on the CPU.

What I think happened here is that in stead of just changing resolution and GPU related load settings, he simply used presets to change between high settings and low settings.

Games for the past 1 or 2 generations give options for physics, particle debris, and smoke/shadows ... these are usually CPU duties.

I can run an experiment to verify. But those bombing runs, in low settings, do not throw up debris ... at high settings it is covered with debris.

Thats why i did the test again using the exact same presets for WiC "very high" and just change the Resolution to address differences.

Again



Will do some more tests this weekend.

That's with Anti-Aliasing and Anisotropic Filtering enabled or disabled ?

[Boschwanza]

Enabled, both 4x

Jack can you test CoHOF and fix the display to 60Hz? Found out CoHOF always enables V-Sync and the sweet spot is around 60 FPS (@all max details 8*AA) so it just would be perfect for a comparision. 8800GTX and 4870 would be nice.
