Performance
Given that the XFX 7800 GTX Overclocked and the EVGA 7800 GTX KO are clocked the same out of the box, we rightly guessed that we would see almost identical benchmark results between the two. As you can see by the graph, the framerates only differ by a few tenths of an fps, which isn't nearly enough to be significant.
For reference, here is our test system:
MSI K8N Neo4 Platinum/SLI motherboard
AMD Athlon 64 FX-55 Processor
1 GB OCZ 2:2:2:6 DDR400 RAM
Seagate 7200.7 120 GB Hard Drive
OCZ 600 W PowerStream Power Supply
When we overclocked this card, we found that we couldn't quite get the memory clock as high as we were able to with the EVGA KO. This is understandable however, given the fact that there were no RAM sinks on the back of the XFX 7800 like there were on EVGA's. However, it hardly matters at all that the memory clock was slightly lower because as you can see below, the framerates were just a
tiny bit lower than EVGA's; again, not enough to be significant. If you'd like more information about overclocking, as well as some information about NVIDIA's frequency scaling issue, take a look at the last article in this series on
the EVGA 7800 GTX KO.
All of the 7800 GTXs performed very well in these three games, which is no surprise given that these are the best graphics cards out here. As you can see, there aren't any huge differences in performance between cards. So, you can be sure that the 7800GTX that you decide to purchase will easily be able to handle even the most taxing games like
Doom 3 and
The Chronicles of Riddick.

I wished they'd not done the spotlight crap on each card but they haven't exactly been putting out much of any reviews worth reading for quite sometime. It would also seem that EVGA put alot of money in their pockets, they are traditionally one of the worst manufacturers of video cards out there, noted in the past for cheap heatsink and fans along with other quaility control issues. Sheesh next they'll be promoting Prolink as the best video card maker. I don't trust these guys anymore, it's not a review it's who gives them the most hmmmmm support lets say instead of coming right out and calling it a bribe, payoff, kickback for putting out a favorable review.Hacp - Tuesday, August 16, 2005 - link
Btw, is anyone else kinda tired by the huge amount of 7800GTX vendor card reviews? I mean performance is obviously going to be similar, and the higher clocked cards are going to perform better........Operandi - Tuesday, August 16, 2005 - link
I tend to agree, all these reviews are pretty redundant. All of them offer the same performance, most/all use the reference design, and most use the stock HSF. If you're going to review each card individually there should be some justification, so far all the cards have been more or less exactly the same.JarredWalton - Tuesday, August 16, 2005 - link
The justification was already given several times in the previous articles. If we had waited to do a 7800GTX roundup, there are still additional cards coming out. If we had done a "roundup" at launch, it would have included the two cards we had at the time. Yes, the reviews are redundant when performance is similar, but we're looking at more than just performance. It's a Catch-22, and we figured getting reviews out in a timely manner would be more useful than waiting a month or two to write a roundup.eetnoyer - Tuesday, August 16, 2005 - link
If that's the case, why not review whatever sample you have at the time of release and wait for a representative sampling to do a roundup? The only conclusion I can draw is that it's a slow time in the lab and you need filler, or individual product reviews means a greater revenue stream due to page hits/manufacturer contributions. Either way, it's rather disappointing for what I've come to expect from anandtech.
