ATI Radeon HD 4850 Preview: AMD Delivers Performance for the Masses

Assassin's Creed
Another FRAPS benchmark, in Assassin's Creed we found a repeatable area of the game to benchmark at the opening of a memory. In this test, we start walking and benchmarking as soon as the memory finishes fading in and we stop as soon as we trigger the next cut scene. We test with AA disabled in all resolutions as AA isn't available above 1680x1050. Because the negative impact of the patch on the performance of AMD cards only happens with AA enabled, we do test with the latest patch applied.
The margin isn't as large as in some of the other games we've tested, but the 4850 does mantain a performance advantage over the 9800 GTX. Again, the margin also narrows as resolution increases, but the 4850 still remains on top.

lol oohhh yeah.. I'll be looking for Anandtech to be reviewing PCP&Ps newest 2kW Power supply with 200amps on teh 12V rail :)rudolphna - Thursday, June 19, 2008 - link
PS. (to PCP&P) Switch to 120mm fans, imagine how loud a 2000watt psu will be with an 80mm fan cooling it :)xsilver - Friday, June 20, 2008 - link
the 80mm fan would require its own psu ;)Clauzii - Thursday, June 19, 2008 - link
There goes the carrot cutter :))Devo2007 - Thursday, June 19, 2008 - link
I can walk into a local retailer and pick one up right now (yes, they are actually showing stock on three different cards).Goty - Thursday, June 19, 2008 - link
Something is VERY wrong if a 1000W rated power supply can't boot a system that draws less than 500W at load. Most sites recommend a 500W-600W power supply to run a 4850 CF system, which should be PLENTY of power.Creig - Thursday, June 19, 2008 - link
That's exactly what I was thinking when I read that part of the article. A 4850 supposedly only pulls 110w. So if I was conducting the review, I would have immediately suspected a defective power supply, not an inadequate one.bob4432 - Friday, June 20, 2008 - link
exactly what i was thinking....ocz quality????JarredWalton - Friday, June 20, 2008 - link
I believe the 1000W PSU having problems was specifically in regards to GeForce GTX 280 SLI - though Anand or Derek would have to confirm. The other factor that I don't know is whether the PSU is the problem or perhaps Derek just has really bad electricity in his house. I know I've had no difficulties with even 550W PSUs and 3870 CrossFire (with a Q6600 overclocked to 3.30GHz).
