Factory Overclocked: GeForce 7600 GT
Our different flavors of 7600 GT are not as varied. We were only able to find two different clock speed configurations for this class of card coming as only slightly overclocked. The stock core speed is 560 MHz, but the majority of variants come in at either 580 or 600 MHz. As this isn't a very large difference, we decided to only test one core overclock at the high 600 MHz speed. As far as memory goes, stock clock speed is 700 MHz (giving a 1400 MHz effective data rate). We increased our stock memory speed up to 750 MHz giving us 600/750 clock speeds for our test.
Right off the bat, we see that the overclocked 7600 GT variants don't make nearly the difference as the overclocked 7900 GT cards we have. There is a slight increase in performance, but we aren't able to come anywhere near the performance of the X1900 GT. These 600/750 clocked 7600 GT cards will be in nearly direct price competition with the X1900 GT, so we can clearly not recommend them based on BF2.
With Oblivion, we still don't see a large increase in performance, and with the variance in our testing its clear that spending extra money on an overclocked 7600 GT doesn't net any dramatic gains.
Our X3: reunion numbers stand to bring home the point that has been made with our other two tests -- overclocked 7600 GT cards don't add much value and really aren't worth more money. If you're willing to spend an extra $30 for a 10% overclock, it makes even more sense to add another $30 or so and get the much faster performance offered by the X1900 GT; it doesn't make sense not to take the plunge if it's in the budget.
Clearly the 7600 GT doesn't benefit from the same advantages that the 7900 GT does when it comes to factory overclocked performance. The results in the remaining tests did not provide any new information: the roughly 10% overclock can improve performance by up to 10%, but the gap between the 7600 GT and the faster cards remains quite large.

I tried comparing numbers for SCCT, FEAR and X3, the problem is Anand didn't bench any of these with AA in this mid-range test, and other sites all use 4XAA as default. So in other words no direct numbers comparison on those three games at least with those two Xbit/FS articles is possible.Although the settings are different, both FS and Anand showed FEAR as a tossup, though.
It does appear other sites are confirming Anand's results more than I thought though.
And the X1900GT for $230 is a kickass card.

The real problem is that virtually every level of a game can offer higher/lower performance relative to the average, and you also get levels that use effects that work better on ATI or NV hardware. Some people like to make a point about providing "real world" gaming benchmarks, but the simple fact of the matter is that any benchmark is inherently different from actually sitting down and playing a game - unless you happen to be playing the exact segment benchmarked, or perhaps the extremely rare game where performance is nearly identical throughout the entire game. (I'm not even sure what an example of that would be - Pacman?)Stock clockspeed 7900GT cards are almost uncommon these days, since the cards are so easy to overclock. Standard clocks are actually supposed to be 450/1360 IIRC, and most cards are at least slightly overclocked in one or both areas. Throw in all the variables, plus things like whether or not antialiasing is enabled, and it becomes difficult to compare articles between any two sources. I tend to think of it as providing various snapshots of performance, as no one site can provide everything. So if we determine X1900 GT is a bit faster overall than 7900 GT and another site determines the reverse, the truth is that the cards are very similar, with some games doing better on one architecture and other games on the other arch.
My last thought is that it's important to look at where each GPU manages to excel. If for example (and I'm just pulling numbers out of the hat rather than referring to any particular benchmarks) the 7900 GT is 20% faster in Half-Life 2 but the X1900 GT still manages frame rates of over 100 FPS, but then the X1900 GT is faster in Oblivion by 20% and frame rates are closer to 40 FPS, I would definitely wait to Oblivion figures as being more important. Especially if you run on LCDs, super high frame rates become virtually meaningless. If you can average well over 60 frames per second, I would strongly recommend enabling VSYNC on any LCD. Of course, down the road we are guaranteed to encounter games that require more GPU power, but predicting what game engine is most representative of the future requires a far better crystal ball than what we have available.
For what it's worth, I would still personally purchase an overclocked 7900 GT over an X1900 GT for a few reasons, provided the price difference isn't more than ~$20. First, SLI is a real possibility, whereas CrossFire with an X1900 GT is not (as far as I know). Second, I simply prefer NVIDIA's drivers -- the old-style, not the new "Vista compatible" design. Third, I find that NVIDIA always seems to do a bit better on brand new games, while ATI seems to need a patch or a new driver release to address performance issues -- not always, but at least that's my general impression; I'm sure there are exceptions to this statement. ATI cards are still good, and at the current price points it's definitely hard to pick a clear winner. Plus you have stuff like the reduced prices on X1800 cards, and in another month or so we will likely have new hardware in all of the price points. It's a never ending rat race, and as always people should upgrade only when they find that the current level of performance they had is unacceptable from their perspective.

I think another advantage of 7900GT over X1900GT is power consumption. I'm not checking numbers of this matter so I am not 100% sure.coldpower27 - Saturday, August 12, 2006 - link
Yes, this is completely true, going by Xbitlab's numbers.
Stock 7900 GT: 48W
eVGA SC 7900 GT: 54W
Stock X1900 GT: 75W

Speech-recognition + lack of proofing = lots of typos"... out of a hat..."
"I would definitely weight..."
"... level of performance they have is..."
Okay, so there were only three typos that I saw, but I was feeling anal retentive.

Not too beat this to death, but at FS the X1900GT vs 7900GT benchmarksX1900GT:
Wins-BF2, Call of Duty 2 (barely)
Loses-Quake 4, Lock On Modern Air Combat, FEAR (barely),
Toss ups- Oblivion (FS runs two benches, foliage/mountains, the cards split them) Far Cry w/HDR (X1900 takes two lower res benches, 7900 GT takes two higher res benches)
At Xbit's X1900 gt vs 7900 gt conclusion
"The Radeon X1900 GT generally provides a high enough performance in today’s games. However, it is only in 4 tests out of 19 that it enjoyed a confident victory over its market opponent and in 4 tests more equals the performance of the GeForce 7900 GT. These 8 tests are Battlefield 2, Far Cry (except in the HDR mode), Half-Life 2, TES IV: Oblivion, Splinter Cell: Chaos Theory, X3: Reunion and both 3DMarks. As you see, Half-Life 2 is the only game in the list that doesn’t use mathematics-heavy shaders. In other cases the new solution from ATI was hamstringed by its having too few texture-mapping units as we’ve repeatedly said throughout this review."

I wish you would do a similar article concerning the video cards for HDTV and HDCP. It is very confusing. Even though certain crds might state they are HDCP, it is not enabled.tjpark1111 - Thursday, August 10, 2006 - link
the X1800XT is only $200 shipped, why not include that card? if the X1900GT outperforms it, then ignore my comment(been out of the game for a while)LumbergTech - Thursday, August 10, 2006 - link
so you want to test the cheaper gpu's for those who dont want to spend quite as much..ok..well why are you using the cpu you chose then? that isnt exactly in the affordable segement for the average pc user at this pointPrinceGaz - Thursday, August 10, 2006 - link
Did you even bother reading the article, or did you just skim through it and look at the graphs and conclusion? May I suggest you read page 3 of the review, or in case that is too much trouble, read the relevant excerpt-
