AMD might be in for a dogfight when Nvidia's Kepler architecture leaves the porch. Early reports suggest Nvidia has a real winner on its hands and that Kepler is such a strong performer, even Nvidia's mid-range cards will give AMD's high-end GPUs a run for their money. The information available is vague and scattered, but it all points to Nvidia stealing back the performance crown.
Charlie Demerjian, who has a long history of being critical of all things Nvidia, sang some high praise for Kepler over at SemiAccurate. According to Demerjian, Nvidia is going to "win this round on just about every metric" with its Kepler architecture, which will trump AMD's Tahiti "handily." Those remarks come after spending hands-on time with a pair of Kepler-based graphics cards and collecting "hard information," though he isn't allowed to share specific benchmarks just yet.
Demerjian's reveal jibes with information information leaked by Chinese website Inpai.com.cn, which is claiming Nvidia's mid-range cards will have the moxie to challenge AMD's higher end GPUs. According to Inpai, Kepler's GK104 architecture will sport a 256-bit interface, 2GB of onboard memory, and have a 225W TDP.
