AnandTech has posted a new article comparing ATI's new X1K family which includes the Radeon X1800, X1600 and X1300. Also included in the test are the NVIDIA GeForce 7800 GTX and GT along with a couple of graphics cards from the previous generation of both ATI and NVIDIA.
While scaling-with-aa on the new X1000 series is very good, will it be good enough to make up for the price difference with competitive NVIDIA hardware? Certainly, the feature set is of value with ATI offering the added benefit of MSAA on MRT and floating point surfaces, high quality AF, SM3.0, and Avivo. But performance is absolutely critical on current and near term games. Currently, many HDR methods avoid floating point output and MRTs in order to maintain compatibility with AA on current hardware. Until game developers shift to full floating point framebuffers or make heavy use of multiple render targets, ATI's added AA support won't make much difference to gamers..
