65nm technology – GTX 260, GTX280
55nm technology – GTX 285 (=55nm GTX280), GTX 295 (dual 285, but 576 MHz)
45nm technology – GTX 300 series, proably Q2 2009
It’s important to know, that 45nm chips use less energy than equivalent 55 and 65nm chips, 55 and 45nm technology also enable higher clocks.
Example – basically same chip:
- 55nm GTX 285 = 183W, 602 MHz
- 65nm GTX 280 = 236W, 648 MHz
Conclusions for 2009
- folding will be faster
- GFLOPS are packed more densly
- it will consume less energy at better performance
