GeForce GTX 280, 260 specifications surface
The 280 has 240 stream processors and runs at a clock of 602MHz, a massive miss on what the firm intended. The processor clock runs at 1296MHz and the memory is at 1107MHz. The high-end part has 1G of GDDR3 at 512b width. This means that they are pretty much stuck offering 1G cards, not a great design choice here.
The 280 has 32ROPs and feeds them with a six and eight-pin PCIe connector. Remember NV mocking ATI over the eight-pin when the 2900 launched, and how they said they would never use it? The phrase ‘hypocritical worms’ come to mind, especially since it was on their roadmap at the time. This beast takes 236W max, so all those of you who bought mongo PSUs may have to reinvest if they ever get three or four-way SLI functional.
The cards are 10.5-inch parts, and each one will put out 933GFLOPS. Looks like they missed the magic teraflop number by a good margin. Remember we said they missed the clock frequencies by a lot? Here is where it must sting a bit more than usual, sorry NV, no cigar.
Be aware that nothing is set in stone.
