Radeon HD 4870 X2 Previewed, AA Performance a Trump Card
HardOCP previewed the ATI Radeon HD4870 X2. In the preview it was pitted against a single BFG GeForce GTX 280 OC (overclocked) and Crossfire X setup using two cards was pitted against two GeForce GTX 280 cards in SLI. Across variable settings, the HD4870 X2 was compared to the GTX 280. In Crysis the competition was neck-to-neck while the ATI cards returned marginally lower average frame rates. In Age of Conan: Hyborian Adventures, the ATI cards outclassed the NVIDIA cards significantly, where the Anti-Aliasing (AA) performance of the cards proved to be a trump-card, with the cards returning over 30% performance increments in both single and Crossfire X configurations over the GeForce GTX 280 OC and its SLI configuration. With the AA bottleneck reduced, the R700 is a monster. Age of Conan: Hyborian Adventures shows what this card is truly capable of, the author of the preview goes on to use "AMD AA Performance FTW" to head a write-up on the AA system. AMD has reworked AA and also a new mode that doesn't tax the video memory as much has been added. The total of 2 GB GDDR5 memory only helps this cause.
The card in Crossfire X peaked 700W though not much is revealed with the power-testing. You can read the article here.
