NVIDIA GeForce 7800 GTX 512 Reviews

Not to put too fine a point on it, but this thing is downright scary. The GeForce 7800 GTX 512 comes with the same G70 graphics processor that powers the 256MB version of the 7800 GTX, complete with 24 pixel shader pipes, 24 texture units, and very strong clock-for-clock performance. However, NVIDIA says 7800 GTX 512 cards will come with a new stepping of the chip, also built at TSMC on a 110nm process, but made with fabrication process tweaks intended to allow for higher clock speeds. Also on the cards is 512MB of GDDR3 memory running at a nominal clock speed of 850MHz, yielding a 1.7GHz effective data rate.

We knew NVIDIA was holding something back when they launched the GeForce 7800 GTX with only a single-slot cooler and 256MB of memory back in July. No doubt the green team was waiting to see what ATI would do with its new high-end card before finalizing a response. Little did we know that NVIDIA’s response would be this forceful. The GeForce 7800 GTX 512 is easily the fastest graphics card on the planet. Even so, its cooler doesn’t sound like a hair dryer, and the card has a little bit of overclocking headroom left.

I came, I saw, I conquered, that’s what NVIDIA had in mind for the past few weeks and exactly what they managed to do… You know I really would like to be angry at NVIDIA for releasing a product in this pricing level, but the 7800 GTX 512MB is just too darn good. It’s not worth to pay 650 bucks to be able to play games, but the thing is, once you’ve bought this young scoundrel, you really won’t regret it!

The bottom line is that the 512 MB GeForce 7800 GTX is one incredible piece of hardware. It allows a better gaming experience in every game we tested over a 256 MB GeForce 7800 GTX. The 512 MB GeForce 7800 GTX provides a better gaming experience in all the games we evaluated than a Radeon X1800 XT. You can buy two 512 MB GeForce 7800 GTX video cards — today — and enjoy the best gaming experience on a consumer PC to date. It is amazing that NVIDIA can put this much punch in a video card and actually provide a cooling solution that is quieter than the slower 256 MB GeForce 7800 GTX.

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.
