The Test, Card, and High Resolution
Before we get down to the performance tests, let's look at our test system.ASUS nForce 4 A8N-SLI Deluxe Motherboard
AMD FX-55
1GB DDR3200 2:2:2:8
120GB Seagate 7200.7 HD
OCZ PowerStream 600W PSU
The card this time around is a single slot solution. With the process shrink to 110nm an insignificant increase in clock speed, NVIDIA has produced a chip that runs at lower power and temperature than NV40. At the same time, the increase in parallelism has served to boost performance.
Layout of the card is relatively similar to the 6800 Ultra, but there are a few differences. We've still got 2 DVI slots (both single link), but the solder point for the silicon image TMDS chip for dual-link DVI is either missing or moved. We will certainly be interested in seeing a workstation version of this part.
Here's a quick recap and summary of the G70 and GeForce 7800 GTX:
302M transistors
Over 300mm^2
110 nm TSMC fabrication process
Single Slot HSF
430MHz Core clock
600MHz GDDR3 256MB/256-bit
8 vertex shader units
24 pixel shader units
16 ROP units
2 DVI and one HDTV / VIVO connection
PCI- Express (demand for an AGP part will be determined and addressed if necessary)
~100W Power
350W Power Supply Recommended (500W for SLI)
So what is all the fuss about? Here's a look at the NVIDIA GeForce 7800 GTX card:
Why high res?
It is important to remember that we tested at resolutions of 1600x1200 and higher because lower resolutions are CPU limited without AA and AF enabled. In many cases the GeForce 7800 GTX don't show much difference in performance with and without antialiasing at lower resolutions. This kind of data doesn't give us much useful information about the card. We have truly reached another plateau in graphics performance with this part: pushing the card to the max is all but necessary in order to understand its performance characteristics.

Does this card play Riddick smoothly @ shader 2++ ?????fishbits - Wednesday, June 22, 2005 - link
"In aboot 5 years i figure we'll be paying 1000 bucks for a video card. These prices are getting out of control, every generation is more expensive then the last. Dont make me switch to consoles damnit."Funny, I can't afford the very best TVs the minute they come out. Same for stereo components. But I don't cry about it and threaten "Don't make me switch to learning the ukelele and putting on my own puppet shows to entertain myself!" Every time a better component comes out, it means I get a price reduction and feature upgrade on the items that are affordable/justifiable for my budget.
Seriously, where does the sense of entitlement come from? Do these people think they should be able to download top-of-the-line graphics cards through BitTorrent? Do they walk around Best Buy cursing out staff, manufacturers and customers for being so cruel as to buy and sell big-ass plasma TVs?
On second thought, get your console and give up PC gaming. That way you can stop being miserable, and we can stop being miserable hearing about your misery.

Funny how the single card deltas here are higher than at any other site.Unwhelmed for the amount of money and lack of performance increase.
Have to commend nVIDIA for ensuring retail availability at launch.

Impressive, but I'm still happy with my X800 XL purchase for only $179. For what it seems, with a 1280x1024 display, I won't need the kind of power this card delivers for a very long time. And less than $200 compared to $600, with still excellent peformance for now and the forseeable future? Hmm, I'll take the former.Lonyo - Wednesday, June 22, 2005 - link
I would have liked some 1280x1024 benchmarks with 8xAA from the nVidia cards and 6xAA from ATi to see if it's worth getting something like a 7800GTX with 17/19" LCD's to run som esuper high quality settings in terms of AA/AF.segagenesis - Wednesday, June 22, 2005 - link
I'm not disappointed. For one thing the price of current cards will likely drop now, and there will also be mid-range parts soon to choose from. I think the transparency AA is a good idea for say... World of Warcraft. The game is loaded with them and too often can you see the blockyness of trees/grass/whatever.#44 - Actually are you new to the market? :) I remember when early "accelerated" VGA cards were nearly $1000. Or more.
Everybody lambasted NVIDIA last year for the lack of product (6800GT/Ultra) to the market, so them actually making a presence this year instead of a paper launch should also be commended. Of course, now what is ATI gonna pull out of its hat?

The screenshot shows very clearly that SSAA provides quite a quality improvement over no AAThe difference is bloody miniscule, perhaps if you used an image SLIGHTLY larger than 640x480 to highlight the difference?

Wowzers. Time to get rid of teh 9800...shabby - Wednesday, June 22, 2005 - link

Hell, for the same price as an SLI setup I can go out and get a 23 inch cinema display...And since these cards can't handle the 30" native resolution anyway, it's a win-win. And yeah, whats up with the quality control on these benchmarks! I mean really, I almost decided to wait for the ATI next-gen part when I saw this (GeForce man since the GeForce2 GTS!)
