The GTX 295 is something of a combination of the GTX 280 and GTX 260. It is clocked identically to the GTX 260, and similarly to it each core has 28 ROPs enabled. But it gets closer to the GTX 280 when you consider that each core has all 240 stream processors and 80 TMUs enabled.

The TDP of the GTX 295 is nowhere near double of the GTX 260, which goes to show that the 55nm respin has indeed led to a smaller heat output. If not for the respin we doubt that Nvidia would be able to fit two cores into a package the same size as that of a single core card.
