Let’s go for a Drive

Our second demo comes from the d2_coast_05 level, which starts off with the Half Life 2 buggy.  After hopping in the buggy we take a spirited drive down the high way, (poorly) avoiding enemies as well as abandoned cars.  There is some exchange of fire towards the end of the demo, and overall the demo is fairly short. 

This demo offers a good idea of general outdoor performance in Half Life 2 where elements such as water are not involved.  There are a handful of explosions that take place while the buggy’s machine gun ignites a flammable barrel that also stress the GPU a bit.  With the absence of water, the flashlight or any reflective surfaces, we find ourselves with a demo that is far less shader bound than our first benchmark, but just as important since not all areas of Half Life 2 are going to be incredibly shader bound.

The fact that there’s basically no performance difference between the top four cards in this test indicates that even at 1280 x 1024, the fastest GPUs from ATI and NVIDIA still find themselves CPU bound in some Half Life 2 scenarios. 

Half Life 2 AT_coast_05 Demo

The relatively flat resolution scaling curves of some of the GPUs indicates that we are still fairly CPU bound here, which, interestingly enough, happens quite often in Half Life 2.

    yawn, i'm too busy enjoy the game (6800gt) to read the article and/or care which card is better :) i'm playing at 1600x1200 0AA/4AF (2.4@3.3/1GB) and have absolutely no complaints, other then knowing that the game will eventually end :(

    #57... poorly :)

    I would also like to to see how the 9200/9000 series Radeons perform too, and if you have extra time, the 8500/9100.

    Again, Thanks!

    #16... that's correct, although the only REAL observation that needs to be made is that Half Life 2 makes heavy use of pixel shaders which is very GPU dependant, and GPU's are just now growing the required testicles to process those shaders :)

    Anand -

    I would like to see how the 6600 performs. As an 8 pipe card, it should perform better than the 9600xt and a little under a 9700 Pro, but it would be interesting to see if that is true. It is a great budget PCIe card along with the x700.

    Thanks!

    nice review downloaded your demos to run on AMD64 3700+ @ 12x 222 = 2664mhz with 1GB BH-5 @ 222mhz 2-2-2-6 1T and Powercolor X800XT PE @ 520/560 and all demo results were within 3-4fps of the reviews :)

    Good reading as always. Would like to see minimum FPS tough. I find it very important to see how low the cards drop when stressed. You can't see that with only average FPS.

    So... wheres the Nvidia SLI versus ATI results??

    Muwahahaha.

    Hey Anand, I have an interesting request. Could you try Rivatuner on your 6800, unlock its pipes, and then bench it again? :P
    Just kidding. Actually, I'm glad you've confirmed what I've been thinking...that AF hasn't been doing much for me. Since I'm running on a lowly 9700, I think I'll just turn it off now, and enjoy a nice speed boost.

    How about throwing a GF 5600 and maybe even a GF 5200 in as well for part 2, as an awful lot of people have them. Ultra versions of either if you prefer.

    I don't have one of them myself as I'm still using a Ti4200, but it would be interesting to see how they stacked up in the DX8 codepath against the Ti4600 you are planning to test. And it should be worth a giggle to see just how "fast" the 5600 or 5200 can manage the DX9 codepath :)

    Thanks to the resolution scaling-graphs this review included and how the fastest cards were generally CPU limited with that A64 4000+ when the resolution was dropped to 1024x768, I'm not sure how much a CPU scaling article for part 3 will show that can't already be quite accurately guesstimated from how different CPUs generally tend to perform in games. But a comparison of the Athlon 64 4000+, against an Athlon XP, a Prescott, a Northwood, and if time permits a fast P3, Duron and Celeron also, would be great.
