Left 4 Dead

Finally we have Left 4 Dead, another title that’s fairly easy on the GPU. The game is approaching (if it has not already hit) a CPU limitation, even with multi-core rendering. 145fps appears to be the approximate cap, and our cards quickly approach this. Because of this cap, the overclocking advantage is only 3%, and the 1% difference between the 5970 and 5850CF is practically immaterial.

Finally the GTX 295 gap is only 17% here, thanks to these cards coming up against our CPU limitation.

    Well my thought is that if amd would release this card on SOI/HK-MG in 32/28nm MCM config at 4 GHz it would leave nvidia wondering what it did to deserve it. And I wonder ... why the heck not? These cards would be business-grade-able and with a decent silicon they could ask for enormous prices. Plus they could probably stick the entire thing in dual config on one single card (possibly within the 300 W pcie v2 limit)... that would be a 40-50 Tflops card and with the new GDDR5(5ghz +) it should qualify as a damn monster. I would also expect a ~2-3k$ per such beast but I think its worth it. 50Tf/card, 6cards/server... 3Pflop/cabinet... hrm... well...it wouldn't be fair to compair it to general purpose supercomputers... buuut you could deffinatelly ray trace render avatar directly into HD4x 3d in realtime and probably make it look even better in the process...

    What no test to check video performance/DXVA? DirectX 11/WDDM 1.1 introduced DXVA HD (Accelerated HD/Blu-Ray playback). Reply

    Clearly nobody buying this card is going to put Crysis on "Gamer Quality" They'll put it on the max it can go. Why is AT still the only tech site in the whole world who is using "Gamer quality" with a card that has enough power to run a small town? Reply

    Why does the 5970 get <= 5850 CF performance, when it has 3200 Stream Processors vs 2880? Reply

    i look forward to buying this, in a few years. Reply

    why they didn't just call it the 5880. Reply

    Ryan,

    I'm a professional L4D player, and I know the Source engine gives out very high frame rate on today cards. The test become silly because there is no different at all from 60 to 300+ fps. So, it all comes down to min fps.

    I suggest that you record a demo in map 5 Dead Air, with 4 Survivors defend with their back onto the limit line of the position of the first crashed plane. The main player for the record will be vomitted on by boomer, another throws pipe bomb near him, another throws molotov near him also. Full force of zombies (only 30), 2 hunters, 1 smoker, 1 tank attacking. (When a player become a tank, the boss he's controlling become a bot, and still attacking the survivors).

    This is the heaviest practical scene in L4D, and it just makes sense for the benchmark. You dont really need 8 players to arrange the scene, I think using cheats is much easier.

    I know it will take time to re-benchmark all of those cards for the new scene, but I think it wont be too much. Even if you cant do this, please reply me.

    Thank you :)

    You're not professional FPS player if you think there is no difference between 60 and 300fps. Reply
