NVIDIA GeForce 7800 GTX 512
Quote:
NVIDIA's efforts with the new G70 earn them the overall performance crown back, and by quite some margin. At 550MHz across the board and with 512MiB of memory running at 1.7GHz effective, it would have been embarassing had that not been the case. That didn't happen, though, and the reference-clocked GTX 512 has no trouble dispatching GeForce 7800 GTX and Radeon X1800 XT to the sidelines.
Quite simply a performance monster, and one that'll take ATI a big effort to beat. The GeForce 7800 GTX 512 impresses hugely, from quiet and efficient cooler, to manageable increase in power draw over the original GTX, with monsterous performance and day-zero availability in-between.
While certain facets of ATI's new Radeon hardware make it more appealing on paper, it's taking time for those technological advantages to come to fruition as part of games, making the latest GeForce hardware even more appealing in the interim. The current real-world performance of both GTX and GTX 512 cement that statement.
