ATI has to work on their drivers. And anyone whos really looked at the 4xxx series, I mean really looked and knew anything about pcs and gpus know that a fan running at 18% isnt going to get the cooling job done, and getting a driver with better power and fan control will solve this problem.
Drivers not running at 100% isn't a new thing by any means, especially not for ATI. They've had problems in the past with drivers not being up to snuff at release, and I don't expect it's any different now. In fact that's the only disappointing thing about the 4800 line IMO, that they couldn't even get the fan control working properly for the launch. That's why I wish more places would do a second review of cards a month or two after release, to see how they
really perform once the drivers are optimized.
Like the parallel instruction processing on the 4800's. Only one game takes advantage of this at all, and that's Bioshock. Look at the benchmark results for that game. While each stream processor in the 280 performs one instruction at a time, the 4800's can perform 5 at once. Developers are going to have to do some code tweaking to take full advantage of this feature, but if they do the 4870 can actually outperform the 280 (and also where the 1.3 vs 0.9 teraflops figures come from). I just don't know if they'll take the time to do that, guess we'll have to wait and see.
It all comes down to drivers and optimized game code, which is why I'm not a big fan of benchmarks to begin with. It's way too subjective and one driver update can change everything.
