The first is basically a cut-down version of the Nvidia GeForce GTX 285, with slightly lower clocks and less memory bandwidth, while AMD’s Radeon HD 4890 sports a few simple changes designed mostly to juice-up clock speeds. Both feature a two-slot PCI Express design and support their respective multi-GPU technology – Crossfire for AMD and SLI for Nvidia. We’ve already covered some of the specifics for each card before, but their simultaneous launch sure makes it easier for users to compare and plan out their next mid-range GPU purchase. You can find some benchmarks over at AnandTech, PC Perspective and Legit Reviews – expect ours soon.
All in all, both cards appear to perform very similarly, perhaps with a slight lead to Nvidia’s card in a few games. We should note however that AMD parts can be bought starting today, while Nvidia is only promising limited availability for now, with the GeForce GTX 275 expected to become widely available on April 14.
