Dual Core Benchmark(?)

[OldDummy]

Greetings All,
I tried this and it worked. I ran the CS video stress test while running Doom3 at the same time.

my box: Shuttle XMS SN95G5 V3 (nForce3 250Gb chipset)
4400 X2 Stock
6800GT AGP 256Mgs stock
2 Gigs. ram 200mhz stock

fps without Doom3: ~90
fps with Doom3: ~19

since the CS stress test is running in the background I would suspect the limiting factor is the cpu. hence: this or similar might be useful as a cpu benchmark.

BTW- Doom3 seemed very playable during the test.

You are stressing the Video card, not the CPU, by running two gaming applications at the same time.

hello mamisano,
How can that be when no frames are shown on screen?

 

[mamisano]

I do believe that the frames are still being rendered by the video card, wether the screen is minimized or not. A better test would be to zip up or maybe uncompress a large file, or run a CPU intensive benchmark like Prime95, etc while benching with CS.. *shrug*.

Exactly, the video card isnt paying much attention to the CS stress test if its not on screen, as thats what the vid card is proccessing. Try it the other way around, have CS:S runing with Doom 3 running in the backround running a demo. And anyways, the way your thinking dual core works isn't too correct. Try running CS:S in a window, Doom 3 in a window and each taking up half the screen. Then you would see a single core cpu would do much worse than a dual, yet both would still be video card bottlenecked.

Edit, oh when an image is not on screen, the video card is not processing it. Try this: run Doom 3 and minimize it, and see how the video temp card drops back to idle temperature, meaning its not performing any tasks.

 

[OldDummy]

yes, either way that would work.

hello monster,
The way I think of dual core is like a thread but at a lower (hardware)level. I feel like each core could be utilized more or less from within a embedded do while loop with threads initialized from each core.
How do you think of dual core?

also, when minimized, there is also less load on the cpu...if you want to try it your self, use task manager and check

Your graphics card is the bottleneck here. As already mentioned, run two CPU-Intensive apps at once and notice the difference.

 

[mdchesne]

run prime and defrag and phototshop multiple-layer rendering together, then compare the scores.

Are you sure that the Video card isn't processing it or at least some of it. One of The advances the Geforce brought over anything before i was the computing of some of the infomation that would be used to create a scene. This would leave me to believe that this stuff would be handles by the Video card nomatter what.
