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 must have missed the SPECViewperf 8.1 test portion, or the Cinebench 2003. Are those on hidden pages along with the PureVideo aspects of the card?These 7800 cards might compete with a mid-range Quadro or Fire card...but I don't know do I !
The reviwers seem to be more interested in which cards come with a BF2 bundle,When you buy 2 for SLI....you can load both...WOW.

You people complaining about "yet another review" are idiots. If you don't wanna read it, don't click it!!!I had not read a single review of any of the cards up to right now. I came to the site looking for one, and I found it. Thank you AT.
I did want to see some comparisons to last generation's cards, like the 6800 Ultra, X800, etc, but I suppose that's found in another article...

Okay this might sound stupid, but are the tests here in SLi or just a single card? I want to be sure of performance because I'm thinking of getting one of these 7800'sbob661 - Friday, August 19, 2005 - link
Both.

I'm glad I'm not the only one bitchin about these articles. I almost fell out of my chair when I saw YET ANOTHER 7800GTX REVIEW on AT.Jarred, I know you've been trying to defend the rationale behind so many reviews of the same tech, but SERIOUSLY, this is ridiculous. I want to believe that you guys aren't just trying to milk the readers for more page hits, but I'm really starting to worry. I'm a big fan of AT, and this kind of stuff is just getting out of hand, IMO.
Please, no more 7800GTX Reviews. For the love of God, please.

Yeah, I think most AT readers now believe this "lets review every 7800GTX card we get our hands on" individually approach is ludicrous. There's so little difference between most of them, and the differences found in overclocking even with the few (one so far) that hasn't been a reference design, are almost certainly down to random variations in the individual core and memory chips. Actually overclocking tests with samples sent from manufacturers are always suspect, and you should always rely on what are reported in the forums from people who have bought the cards to get a good idea on how well they overclock. I agree with the idea of AT overclocking the cards to find how far they go, but that is really only a minor point of the review.For all intents and purposes, all the 7800GTX cards you review are identical, unless they have a quieter fan, or a large heatsink that takes up extra slots which would deserve mention for that reason. The game bundle may differ and you might mention that, or what dongles and cables are included, but that's about all that matters and it certainly doesn't warrant a seperate review for every card.
With all these 7800GTX reviews, I seem to have missed AT's review of an X800GT card which will be of more interest to far more readers. I'm sure I'm not alone in wishing you would call a halt to these ongoing 7800GTX reviews that only a tiny minority of your readers will buy, and instead look at more mainstream products and how they impact that market sector. AT is becoming more elitist by the day, what with concentrating only on the very top gfx-cards, CPUs, memory, etc, and will lose its readers if it continues down this path.

This is not the Overclocked version of the card.HardwareD00d - Wednesday, August 17, 2005 - link
actually, it is overclocked:Memory clock: 1.25 MHz (vs. 1.2MHz Standard)
Engine clock: 450 MHz (vs. 430MHz Standard)
but not as much as the version in the review. Still, seems to be a damn good deal considering the card is being scalped for close to $600 at many places.

This and previous reviews of 7800GTX cards were extremely superficial. After reading the last review many questions still remain unanswered. We all know that we won’t see miracles if all the cards use GPUs clocked at similar frequencies. In other words, I don’t care if one card is 2 fps faster than the other in Doom3 at 1600x1200, what I’m interested in are features, for example:- What is the max DVI resolution for both DVI slots?
- Can I drive two Dell 2405FPW LCDs with a single 7800GTX at 1920x1200@60Hz? I had a bad experience in the past with nVidia cards, where max. resolution on primary DVI was limited to 1600x1200. Only the secondary DVI, connected via silicon image TDMS transceiver was able to drive 2405 panel at 1920x1200.
- Can I drive 30” Apple cinema Display at 2560x1600? In other words, is there any 7800GTX card available with a dual-link DVI slot? I know that so far only some quadro cards are able to drive hi-res displays.
- I don’t remember TV-OUT was tested in any review. What is the max TV-OUT resolution 720p, 1080i?
- Which inputs are present on the card? S-Video, Composite?
- Can I downclock the GPU to let’s say 200MHz or even lower to achieve silent operation during normal work?
