AMD Radeon HD 7990 Released: Dual GPUs and 6G of Memory for $1000

Today AMD has officially unveiled its long-awaited dual-GPU Tahiti-based card. Codenamed Malta, the $1,000 Radeon HD 7990 is positioned directly against Nvidia's dual-GPU GeForce GTX 690. Tom's Hardware posted the performance data. Because Fraps measures data at a stage in the pipeline before what is actually seen on-screen, they employed Nvidia's FCAT (Frame Capture Analysis Tools). ... The 690 is beating AMD's new flagship in six out of eight titles. ... AMD is bundling eight titles with every 7990, including: BioShock Infinite, Tomb Raider, Crysis 3, Far Cry 3, Far Cry 3: Blood Dragon, Hitman: Absolution, Sleeping Dogs, andDeus Ex: Human Revolution."OpenGL performance doesn't seem too off from the competing Nvidia card, but the 7990 dominates when using OpenCL. Power management looks decent: ~375W at full load, but a nice 20W at idle (it can turn the second chip off entirely when unneeded). PC Perspective claims there are issues with Crossfire and an un-synchronized rendering pipeline that leads to a slight decrease in the actual frame rate, but that should be fixed by an updated Catalyst this summer.
