Well I've heard that ATi's memory management is better,
but this --> http://www.pcgameshardware.com/aid [...] 537&page=6
left me speechless, I had to share it.
For those too bored to click, it is a link of Oblivion with Qarl's Texture Pack (quadruples the size of textures).

On a side-note I've read on other forums that the Crysis benchmark is not very consistent and they should not be trusted, but this is too much to be ignored.

Check out that 2560x1600 x8AA x16AF.
I know a memory bottleneck when I see one, and the GTX280 is bested down by the game, while the "puny" 4870 with 512MB sticks up at double its framerate.

Then again the 9800GX2 rolls over and dies when 8x AA is applied comparing to 4x AA (1/4 of 4xAA performance) while 9800GTX "only" loses half the framerate.

Inconsistent article or normal behaviour?
Is ATi's texture compression THAT much better? It can't just be GDDR5.
Any other thoughts?

I'm most interested with Oblivion's Qarl's results. I use a 8800GTS G92 512M and the 512M limit has become an issue. I had to cleverly pick and choose pieces parts of Qarl's and other settings to keep the memory footprint down so I could keep framerates up, certainly higher than what is being reported. All of those numbers are low.

Judging by these results, not one card is managing more than 512M correctly even when they have more than 512M of local video memory, as what happens when you run Oblivion, Qarl's and HDR and FSAA and other memory utilizing add-ons.

I would have expected the wider memory bus, more local memory, new architecture and game engine maturity incorporated into drivers would have given the GX260/80 a much more impressive performance

Many of those numbers seem suspiciously low, as it appears the 9800GT+ is on par with the GTX series' results, but the 8800 GTX ULTRA falls behind, when it is hardly inferior at all in this specific measurement.

There is no fixed benchmark in Oblivion and one hiccup can skew the results, which is almost guaranteed.

I don't play Oblivion, however I found it rather interesting that the 3870x2 which has serious AA problems in nearly every game i've seen it reviewed under - outperforms everything but the 4870x2 with 8xAA enabled at 22/26" resolutions

Me, personally, that makes me question it quite a bit.

But I don't play Oblivion, so take my observation with a grain of salt.

So this is good news to me as an HD4850 user?
