[PC Game Hardware]GTX 280 Overclocking and Extreme FSAA Performance

An interesting review showing the effects of high levels of Anti-Aliasing and overclocking has on the GTX 280 vs the 8800 Ultra.

Quote:
Yesterday's benchmark revealed the strengths of Nvidia's new graphics flagship: high resolutions combined with FSAA. With Supersampling FSAA already at 1,680x1,050 calculation is already more complex than with 2,560x1,600 and normal FSAA. Thus the GTX 280 can show off again. In every test the transistor monster can take place itself in front of the Geforce 8800 - the complexer the calculation the bigger the gap between them. Especially with 16x OGSSAA and 32xS the GT200 card is even able to get playable frame rates from time to time. The "time-honored†G80 board is out classed.

Overclocking the GTX 280 results in 23 percent better performance at best, compared to Nvidia's specifications - this matches the GPU clock alterations exactly. Under those conditions the GTX 280 often reaches twice the power of the 8800 Ultra.

But how does it goes comparing against 9800GX2

Wow, it overclocks alot better than previous cards.

And other benches stipulate that the 9800GX2 is only slightly more powerful.

I would like to see the overclocked versions also compete against the stock versions. Ex GTX 280 FTW (eVGA).

There is another test on the site of the GTX 280 vs 9800GX2 here in some newer games like Age of Conan, Assassins Creed, and Mass Effect.

The GTX 280 seems like good overclocker specially on the memory clocks. On the [H]ard Enthusiast test they overclocked the memory (with stock cooling) to 1325mhz (2650mhz DDR) which is darned good for GDDR3 memory. That memory clock speed takes the memory bandwidth to 169GB/Sec.

It was a good review but with a pretty big flaw. They are using an overclocked GTX to represent an Ultra? As far as I know the Ultra dominates the GTX in terms of overclocking. The review showed the GTX at 675/1674/1080, which they put as an overclocked Ultra, but an overclocked Ultra should easily be able to get at least 700 core with 1100 memory.

I haven't seen many 8800GTX's reach those speeds.

Where have you been for the last year and a half? 675 was basically the stopping point for the G80 on the GTX, it went to 700 with an Ultra and went higher if you gave it a voltmod and watercooling. Heat has always been the issue with the G80.
