According to the rumor mill, with credits going to Fudzilla, there have been confirmed leaks detailing Nvidia's GTX 580. There's been talk that the card has been sent to journalists for sampling and it will sport the GF110 GPU. This time, all 512 CUDA cores will be enabled... but let's just see what happens on November 9th when Nvidia officially launches the card. It's speculated that the card will be clocked at 772MHz with 512 shaders and 2200MHz memory. Additional rumors have it being more efficient than the GTX 480, with a TDP of 244W as opposed to the GTX 480's 250W of typical load power. Maybe it's just me, but it seems these "leaks" are a pre-emptive strategy geared towards getting enthusiasts excited about a product to hold off people from buying AMD's latest 6850/6870 release. We'll probably get some "leaked" rumors of the 6950/6970 specs soon after the official Nvidia announcement.
Powerfull GeForce GTX 580 Has Vapor Chamber Cooling and Runs at 47dB
NVIDIA has put up on Youtube a video of their
Power was better than GTX480 by a significant margin. Cooler and quieter too. Uses vapor chamber so it basically got all that heat piping into the shroud and helps cool it. I forgot exact numbers. It wasn't mind-blowingly cooler/quieter but a nice bump.
Compared to GTX480, GTX580 was 15% faster in DX9 games, 20% faster in DX11. (Eyeballing it, I didn't have a calculator with me.)
Overclocking was limited to 8% at stock volts (core/shader), a bit higher in memory. Overvolting helped the clocks go up somewhat more.
5970 was benched using the broken 10.7 cat drivers so I wouldn't bother reading TPU's comparison. I'm sure other sites will use latest drivers, though. That said, the GTX580 was in-between the 5970@10.7cat and GTX480.
$499 pricetag.
NV tinkered with some of the internals so it's not just a GTX480 with all 512 cores and a clockspeed bump. They took out ~200 million transistors and shrunk the die by ~9mm2.
