Nvidia wants to continue its big monolithic, high-end strategy as this might be a better thing than the two-chip approach used by ATI. This strategy didn’t actually work well this time round, as Nvidia was pushed to launch Geforce GTX 295, a card with two GT200b, 55nm chips simply as its single high end GT200 GTX 280 at 65nm was not enough to beat ATI’s two-chip X2 card.
Next generation high-end, the one that comes after GTX 285 and dual chip GTX 295, will again be a big chip; but it looks that Nvidia keeps a dual card approach as a reserve that can help it fight against ATI.
We expect that the next chip, the one that comes after 55nm GT200b, will again be a similar chip with shaders clocked higher than the GPU clock and many parallel stream processors at higher clock, but we know very little about this 40nm chip.
