NVIDIA GeForce 7800 GT: Rounding Out The High End

Half-Life 2 Performance
Half-Life 2, another graphically-intensive game, should see lots of improvement as well. Unlike Doom3, Half-Life 2 gets playable framerates at the higher resolutions with AA enabled on the 6800 Ultra, but you will still see a sizeable improvement with an upgrade to the 7800 GT.
Without AA, we see a modest 15% gain at 16x12, and 37% gain at 20x15 with the 7800 GT over the 6800U. With AA enabled, 16x12 gets a 42% gain and 20x15 gets 54.5%, showing that Half-Life 2 does a slightly better job with AA than Doom3.
Again, we see much larger gains with the 6800 Ultra in SLI configurations. The highest increase is 88.7% at 20x15 with AA enabled, about a 30 fps increase. 16x12 AA gets a 68% increase, and without AA, there's about a 22% increase at 16x12, and 59% increase at 20x15. This is more evidence for the superiority of the 6800U SLI over the 7800 GT, performance-wise, but whether or not it's worth the price as well as the extra power demands is debatable. Also note that other than 20x15 4xAA, the 7800 GT SLI and 6800 Ultra SLI are nearly the same performance. The extra memory bandwidth of the 6800 Ultra seems to help it match the additional processing power in quite a few tests.

Damn it! That's the only bench (besides UT2004) that I care about. :)

Thanks guys for the updates!!!So - Thursday, August 11, 2005 - link
For those of us who would like to get a better idea of how the 7800GT compares to the 6xxx generation of cards, might you guys consider throwing 6800GT/Ultra (non SLI, preferably) numbers on the benchmarks for comparison?bob661 - Thursday, August 11, 2005 - link
I don't if this is part of the problem, but like the others said, could you guys add in some 6800 series benchmarks so we can compare?JoshVenning - Thursday, August 11, 2005 - link
Hi all,Sorry guys, we're having problems with the site. The article should be up and fixed in about 15 minutes. Thanks for letting us know about the problem

Oh, I see, it's all pages except BF2. How STUPID.neogodless - Thursday, August 11, 2005 - link
I'm sure everyone contributing comments has1) never made a mistake
2) never had a computer problem
3) enjoys being degraded

First off, lots of graphs are not loading.Second, use some common sense. I am upgrading, not downgrading. I want to see what performance I will get over my 6800GT, not how much less I will get than the $600 GTX.

And now, for some common sense. :]If you're a 6800GT owner, *and* looking to upgrade that still not-so-cheap and capable beast, you're not so much worried about the money as most people are, but you'll be very interested in performance.
So, wouldn't you want to know if you should spend ~$450 for a more modest upgrade (compared to that 6800GT), or ~$550 for the most performance you could get without going SLI?? If the ~$100 difference is a very big deal to you, you wouldn't be looking to upgrade your 6800GT. (And yes, I know these prices fluctuate, and may each be more or less, but the point is still valid.)
Not including its direct sibbling in the benchmarks, the GTX, now that would have been lack of common sense. Honestly.

Update:Thanks for adding them. Without them the benches were almost worthless.
