AGP Battle: GeForce 7800 GS VS. Radeon X850 XT

Post by **Yoon** » February 20th, 2006, 12:15 am

Welcome to Yoon's Corner, tobiasboon. Thanks for sharing your X800 XT PE vs. 7800 GS results. Congrats on getting to 500/1400 on your 7800 GS; I could only do 480/1380 stable.

It's great to see more results on how a well OC'ed X800 XT PE fares against a well OC'ed 7800 GS, as well as seeing how they perform on a OC'ed P4 Prescott system.

Your results seem to confirm what I found in that the X800 XT/PE, X850 XT/PE and the 7800 GS perform very close to each other.

Some of the results dont follow trends exactly how I expected, the HL2 Lost Coast results are very odd, but those are the numbers I got.

Yep, I got very similar results in the HL2: Lost Coast test when AA/AF is applied. When I first got the results, I re-ran that test again on my X850 XT, several times to make sure it wasn't a glitch or something. It's very surprising to see how well the 7800 GS does in this test; it is one of the very few situations where the 7800 GS totally dominates over a X800 XT/X850 XT.

I just modified my original post as Id stated the wrong clocks for the 7800GS on the Far Cry tests (were listed as 1400MHz not 1450MHz as it should be).

Looking at your Lost Coast results with antialiasing enabled almost confirms my own results, whether its some kind of driver bug or other issue I dont know, but the difference between the 7800GS and X800XT PE is huge on that particular test.

FEAR seriously slays both cards and the framerates on both in the resolution and settings I tested would be unacceptable for me so I may rerun them with 1280x1024, 16x AF, no AA which Id hope should average around the 40fps mark for both cards.

Im also considering running tests comparing Transparent Antialiasing vs Adaptive Antialiasing and if I do will post back with those results as well.

Thank you for the welcome btw.

Hi there,

even I couldn't give you some results between this two graka , I could provide some information about the difference in my system before and after:
No Overcloaked

3 Ghz PIV
2 Gbyte PC400 HT Ram

3DBenchmark 2005
NVidea 5900 Asus : 1100 Pts
NVidea 7800 GS Leadtek : 5400 Pts

X3 Demo Loop:
NVidea 5900 Asus : 11 Fps
NVidea 7800 GS Leadtek : 39 Fps

So now I could play X3

but waiting for Oblivion ...

PS:
Also Fifa 2006 improved in that way, that players look more 3D and the AI plays better (seems has more time to decide what to do) and even more different movements. So it really feels like a different game.

So will try to overclock it, maybe ...

Hi vonthoma, thanks for sharing your 7800 GS results.

I'll be getting The Elder Scrolls IV: Oblivion as well; I wonder how well it will perform on a 7800 GS, considering this game is already putting a hefty load on the 7900 GTX & X1900 XTX cards.

Oh yeah, regarding the 7800 GS AGP, I just read this article on The Inquirer:

Gainward's AGP is a wolf in sheep's clothing

I found this quote in the article very interesting...

This card's magic is that it actually has G71, Geforce 7800 GT PCIe core bridged down to AGP. It has G70 core with full 20 pipelines that worked at 425 MHz and famous BR2 chip managed to bridge the card down to AGP

Although it's going to be called a 7800 GS, in reality, it's more like a 7800 GT, since it's using a G70 20-pipe core (current 7800 GS models use G70 16-pipe cores with 8 ROPs disabled).

As seen from the results in the article, Gainward's "wolf" beats the 7800 GS by a good margin.

While it's great that AGP users will be getting yet another faster graphics card, there are only two bad things: i.) Gainward pulled out of the North America market, so NA consumers will be unable to obtain them from NA retailers. ii.) The Inquirer is reporting that these will retail in Europe for around
