Crysis Warhead Analysis




1680x1050    1920x1200    2560x1600


Like in CoD, we are seeing NVIDIA dominated performance. AMD's 3-way solutions can hold their own against the rest of the hardarwe out there, but NVIDIA sets the bar here in terms of raw performance.

While other tests don't show any real need for 3-way graphics, Crysis isn't playable at 2560x1600 with single GPU options under these settings. Even at lower resolutions Crysis just seems to absorb what's thrown at it. The 512MB parts do take a bigger hit at the highest resolution than the higher memory hardware out there also.




1680x1050    1920x1200    2560x1600


Scaling is decent, but we would prefer it to be higher even so considering that to get closer to getting what you pay for we would need to see 200% scaling with 3 cards. NVIDIA hardware seems to scale much better than AMD hardware in this test.




1680x1050    1920x1200    2560x1600


Looking at how the hardware scales from 2 to 3 GPUs, we can see that AMD's 4870 1GB shows good improvement despite the fact that it trails in the 1 to 3 GPU scaling chart. 512MB hardware struggles a lot in this as well. The other hardware does scale really well up at 2560x1600 where it counts.




1680x1050    1920x1200    2560x1600


Because this game is very graphically intense even when not set to the maximum settings, not all the cards can score any "value" even at the lowest resolution. The ATI Radeon HD 4850 fails to break the 25fps barrier in any test, so it gets a value of zero across the board. The 9800 GTX+ 2-way option isn't that shabby until 2560x1600, and the 4850 X2 posts some good value. We still have single cards at the top of the value chart until we hit 2560x1600 where single cards fail to offer any value (as well as some 2-way solutions). At that point 2-way solutions that offer some level of passable performance give more for the money with the GTX 260 3-way option leading the pack of our recently added tests.

This game shows the most casualties in terms of our value threshold, but hopefully it will help show which cards are actually worth comparing here.

And if it is not a "Devil's 3-way"...

That's with two guys.

only one of the girls needs to be hot, the other will be so busy licking your balls it wont make a difference.

So basically, by Spivonious, 268 days ago
I find it interesting that the 4870 512MB leads the value charts at "normal" resolutions (still way higher than I run).

I think as a follow-up to this series you should look at playability statistics and see if getting anything more than the 4870 512MB is worth it at 1920x1200 and below.

value system by smartalco, 268 days ago
I don't like that you use 0 for those that score under 25 FPS, specifically because that is under 25 at the res/settings you use. If a card scores 24 FPS at 1680*1050 with maxed settings, what that really tells you is that if you were to drop to half the AA, or turn down some other setting, is that you could still have a perfectly playable game. It seems to me, that giving them a value rating of 0 is acting like everyone has to play on max settings, and if it doesn't meet the standard, its useless.

IDK, just me talking, I'm going to be happy with my 4850 for quite some time.
Still an excellent article.

RE: value system by DerekWilson, 268 days ago
i've actually got the graphs without the 0 scores in the article front to back -- just commented out at the moment ... i wasn't sure which one to go with until the last minute, and i thought about putting both in (but that wouldbe really redundant for games that no card had trouble with)

i could do some more complex web programming, but i'm not a web developer and i hate javascript ...

thanks for the feedback. i'll be taking it into account in the final article on 4-way.

also, if you wanna see the value numbers for the single and dual cards that scored less than 25 fps, you can still look at the first article and see them.

I think demonstrating crossfire using 4850s with 1 GB of ram each would have created a "sweet" price/performance result.

These 4850s show us what happens when there isn't enough memory to compliment a video card's processing potential.

Derek,

Please keep the new way. I was one of the proponents of the zero rating after the last article and it shows nicely what can and can't handle a given resolution. Sure you can turn down the eye candy, but that's not the point of the article...especially when you are talking about 3-way.

We could just turn all the settings down to medium and a single 4850 would be the value king! (/sarcasm)

New drivers? by Burrich, 268 days ago
Would the recently release Catalyst 9.2 drivers improve any compatibility or fps issues? Their release date was 2/20.

Reply
RE: New drivers? by DerekWilson, 268 days ago
The recently released 9.2 catalyst drivers are basically the 8.12 hotfix drivers with some additions to support performance and scaling in recently released titles. So not really.
