The NVIDIA GeForce 7900 GS: A Closer Look

Leadtek
The next 7900 GS we are looking at is from Leadtek, and it has a different heat sink design.
The heat sink and fan combo is a bit larger on this board than the reference 7900 GS, giving it the appearance of something similar to the 7800 GS. The design on the heatsink is simple, with the WinFast logo and the card name over a black heatsink with blue stripes across it. This card also comes with two games included in the bundle, Serious Sam 2 and Spellforce 2.
Something slightly unique about this 7900 GS is that it's one of the two cards we have for this review that has a factory overclock on the memory clock as well as the core. The extra 40MHz of memory speed (700MHz verses the standard 660MHz) won't really give this card a big edge in performance over the other cards in this review, but it's still a nice bonus all other things being equal. Depending on the game, the core clock speeds of a graphics card will usually have a larger impact on performance than the memory clock speeds.

I'd like to see how these cards compare to a 7600GT, as I currently own a eVGA 7600GT KO, and will be upgrading my current system to a conroe, and MAY consider another GFX card, especialy one this in-expencive, or maybe I'll just go the 7600GT SLI route . . .Spacecomber - Tuesday, September 19, 2006 - link
Josh probably would have done well to provide some more specific reference to the previous two Anandtech articles on the the 7900GS that Derek did, including some links to those articles, since that is where you'll find more information on how these cards compare to a wider array of video cards, including the 7600GT. However, while they tested the new 7900GS in a SLI configuration in one of those prior articles, I don't think they inclduded results from a 7600GT SLI for comparison.I'm not sure what article might have that in it for reference.

In the Oblivion test, why are do the X1800GTO and 7800GT both score 0 in the bar graph, despite their non-zero results in the line graph directly above it?Josh Venning - Tuesday, September 19, 2006 - link
Thanks for pointing this out. It's been fixed.Woodchuck2000 - Tuesday, September 19, 2006 - link
...of one of these working in SLI with a 7800GT?I'm assuming that the answer is roughly 0, but with such similar specifications, is there any hope? I've got a single 7800GT in an SLI board and can't find a second at the moment.
Re fan power consumption, you're unlikely to be looking at more than 1 watt difference across the board.

Find someone with a 7800GT and offer them one of the 7900GS Overclocked versions in exchange.DerekWilson - Tuesday, September 19, 2006 - link
At this point, NVIDIA will not support SLI between prodcuts with different names -- even if they have the same pipeline configuration.We have mentioned that this would be quite a good incentive for people to get behind SLI, but it seems like they are worried about implying that it could work in cases where it can't.
Our suggestion is to make sli between parts that could work together an unsupported option. We haven't been able to figure out how to hack the driver to allow it, and we don't think NVIDIA will allow it.

Don't you think that testing these cards without any FSAA is being kind of lazy? Anyone knowledgable enough to actually read this review most likely will be using FSAA, so that kind of makes this a waste....Also, did you at least turn the drivers up to high quality?

Mmm, most people don't use FSAA. Majority of users can't tell a diffrence with it on or off.VooDooAddict - Tuesday, September 19, 2006 - link
I'd have to agree. Most people with 1280x1024 LCDs that I've met prefer to leave FSAA off (if they even mess with the setting) to get the best possible frame rates. While the max framerate might not dip below 60 ... it's the minimum framerate spike that will effect competition.I used to enjoy turning on FSAA for Everquest, but for anything more FPS competition oriented I don't know anyone who uses FSAA unless they have SLI. (Which would be why they got SLI ... to run FSAA without noticable impact to framerates.)
