NVIDIA GeForce 7800 GTX 512: More Than Just More Memory

Day of Defeat: Source Performance
It seems that there is some sort of ~60 fps cap that we can't get around in Day of Defeat: Source. We made sure that vsync was disabled and that max_fps was set to a high value, but nothing seemed to remove the framerate limit. We tested the game with all the settings on the highest possible level but AA (which was toggled between disabled and 4x).
Without AA, cards don't really start to distinguish themselves in performance until above 1600x1200. The 7800 GTX 512 does very well under these conditions and leads just about everything including most SLI numbers (with the frame rate cap, CPU overhead of SLI starts to decrease the performance benefit).

EXACTLY!!!! Which IS the point of these tests! They are intentionally isolating the GPU's because...that's what they're testing! LOL! Anand's been testing the latest and greatest for years now. This is NOT something new here.Brunnis - Monday, November 14, 2005 - link
Huh? Peak FPS? They're testing average FPS. Do you think they would be stupid enough to measure peak FPS. That would make very little sense...Cygni - Monday, November 14, 2005 - link
No way. Different sound solutions have different overheads, different overheads have different effects on the cards.Sound off. Its the only way to get an acurate comparison between the cards.

Holy crap nearly 300watts of power just for the GPU! This could be the first card that really puts a gaming system into the realm of NEEDING a 500watt high-efficiency PSU.jkostans - Monday, November 14, 2005 - link
Read he article, it's system power. Meaning at the outlet. Actual power drawn from the PSU by the system components assuming ~75% efficiency would be around 210 which isn't all that much if you think about it. A 400w PSU is plenty for this system.bloc - Monday, November 14, 2005 - link
Getting silly.The mainstream people are still looking for the best value for $200. I hope ati doesn't overreact and start releasing a bunch of vid cards to gain the title back. Wait 4-6 months for the next iteration. The mainstream wants 60 fps @ 1024. Offer the best bang for the dollar and we'll rave about it.
Don't waste money on tons of iterations. Just lower the cost of current generation to compete. Anand will do a FPS vs $$ soon enough, cause that's the real measure of value.
For $700 buy an xbox 360 or take a Winter vacation.

Well, my 6800GT can't give me playable in 1280x1024 for CoD2, so that's what we've come to. I would have thought that a card like this wouldn't be needed until sometime next year, but already the level of hardware required by games has takena significant jump since Doom 3.Calin - Monday, November 14, 2005 - link
Some users prefer to run their 17" or 19" LCD at the native resolution (1280x1024). This means they want good performance at that resolution. As for those that have bigger screens, they want even better performance.Even so, there are lots of good games that run ok on old video cards (even budget old video cards). But if someone chooses a certain level of quality (antialising, resolution, HDR, ...) they want, is great to have a site that present different options (cards).

Isn't the PS3 supposed to be using a 24-pipe nVidia core running at 550MHz as well? If so, that would almost certainly mean that this card is faster as I bet they are using very similar cores, but the 7800GTX512 has much faster memory than the PS3.And of course there's always SLI if you want even more performance...

heh ... sli ... let's see, $1400 on two video cards or on 3 or 4 next gen consoles ... or on lots of other cool hardware/software/tvs/movies/games ... whateverits a fast beast, but its just too pricy :-)
