7800GTX 512MB - From all over
The race for the performance crown between ATI and Nvidia almost seems like the fable about the Tortoise and the Hare. For the past 4 months, the Hare (Nvidia) has been taking a relaxing nap and reaping in the profits since it raised the bar with its GeForce 7800 GTX in June. Now, just as the Tortoise (ATI) catches up to the Hare riding on its new 512MB Radeon X1800 XT, the Hare awakens and revs up its own 512MB response: the GeForce 7800 GTX 512MB.

Its just over a month since ATI launched their X1800XT. The X1800 was
ATI's response to the very successful Geforce 7800GTX which Nvidia
launched in June, and has since become a part which has proved very
popular in enthusiast circles. For a very long time there were a lot of
rumors that the X1800 would feature 24 or 32 pipelines when launched by
ATI and completely blow the GTX away however such a part never became a
reality and instead the product ATI launched was a 16 “pipeline” part with
architecture and clock speeds which allowed it to exceed the performance
of the 7800GTX in most titles, though not by a huge amount it has to be

...So with the XT making it into retail just last week we have our first
look at a retail model in the form of the Sapphire Radeon X1800XT 512mb
and we take our first look at Nvidias response to the X1800XT, the
reference model Geforce 7800GTX 512mb."

We have tested out the GeForce 7800GTX 512MB edition in single card and SLI mode. We compare it against single card and SLI mode 7800GTX 256mb and 7800GT as well against Radeon X850XT PE single card and CrossFire mode as well as against the Radeon X1800XL.

We just posted our preview of NVIDIA's new high end graphic card GeForce
7800 GTX 512MB. This is a short preview of what will come later when the
world's best 3Dmark overclocker and Sweden's foremost processor
overclocker, Marcus "Kinc" Hultin and Robert "Crotale" Kihlberg, is doing
their best to overclock both GeForce 7800 GTX 512MB and ATI Radeon X1800
as far as possible.


Although the GeForce 7 Series has been very successful so far, we all knew NVIDIA was keeping something up its sleeve to respond to ATI's 512MB Radeon X1800 XT. Many of you probably already know the name of NVIDIA's response (a.k.a. NVIDIA's new flagship card) and might even know what it looks like. Well, today is the official day that we can tell you all about it. Get ready for another hard launch as NVIDIA continues the trend it started to end paper launches, and say hello to the GeForce 7800 GTX 512.

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.


This new 512MB version of the GeForce 7800 GTX, you see, doesn't run at the 430MHz GPU and 1.2GHz memory clocks that the standard version does. Oh, no. This card is intended to compete with--nay, embarrass--ATI's ultra-high-end Radeon X1800 XT, the recently crowned king of single-card graphics performance. NVIDIA's not calling it an Ultra, but they might as well be, with clock speeds of 550MHz for the GPU and 1.7GHz for the memory. That, my friend, is fast. We're talking about 13.2 gigatexels per second of fill rate and over 54GB per second of memory bandwidth. Those towering specifications could allow this Bugatti Veyron of the graphics world to lay the freaking smack down on the Radeon X1800 XT. And the prospect of running a couple of these monsters in SLI captures the geek's imagination like a wayward pair of Carolina Panthers cheerleaders.

We have, of course, subjected the GeForce 7800 GTX 512 to a grueling battery of performance tests using the latest games at a range of resolutions, including the sick and disturbing 2048x1536, just because we could. Can NVIDIA's new $649 beast show up ATI's Radeon X1800 XT? Will a pair of these in running in tandem cause the lights to dim in Damage Labs? We're about to find out.

We have one of the first reviews of the new Nvidia 7800 GTX 512MB card today. With enhanced clock speeds, could this be the card to take back the performance crown from ATI's X1800 XT? We find out in a series of real-world gameplay evaluations.

any good ones in there worth reading after having checked out the [H] and Anandtech write-ups?

NVIDIA GeForce 7800 GTX 512: More Than Just More Memory

NVIDIA GeForce 7800 GTX 512 MB Preview

I need one more day to finish reading them ;)

jmke 14th November 2005 17:16

[H] testing is lacking performance numbers at 1280x1024, other than that their testing method is almost flawless (CPU scaling is missing also)

Sidney 14th November 2005 17:23

[H] is only a preview; and have promised to have follow up in later days.

jmke 14th November 2005 17:32

yes but I don't think they'll add the things I mentioned;)

jmke 14th November 2005 17:41

the Anandtech review really shows that the 512Mb is not what makes this 7800GTX so fast, as the difference between 256<>512 is almost none existant.

the increased Core and Memclocks really push this card to the top of the pack

anybody wants two 256 mb cards?
I could sell them in an sli-pack for let's say 700 euros :)

Gamer 14th November 2005 20:13

sold :)

jmke 14th November 2005 20:15

Don't be dumb Calantak.. I hate it when you throw money out of the window.. :(

@Gamer: Quad SLI is not supported yet, what are you going to do with 4 Geforce 7800GTX cards?

damn rich/ignorant people :grum:
