I must admit since moving to the 8800 series of cards the picture and colour quality of the games is far superior to the old 6 and 7 series cards. I should imagine the the 92 chip is even better the the 80 chip as some serious rop improvements have been made.

That depends upon how you define "ROP improvements", Teafs.

They've played around with the way that the antialiasing is actually done due to the G92 having less grunt in the ROP department than the older G80 GPU. More efficient routines have had to be devised and they don't even come close to matching the older antialiasing routines according to my eyes.

The G92 only has 4 ROPS and they each have a 64-bit limited pathway to memory. As the memory bus-width is 256 bits, you can't run more than 4 ROPS simultaneously.

This gives the G92 less potential memory bandwidth than the older G80 when it comes to antialiasing and means that the only way to get performance up in the antialiasing department is to ramp up the clock speed.

The G92 seems to be a classic example of grunt over grace and will struggle to ever match even the old ATI RV570 GPU used on the X1950Pro for performance in the antialiasing department unless they increase clock speeds dramatically.

Cheers, Slipstreem.



System specs: "Phoenix" - Intel C2D E4500 overclocked to 3GHz with ACF7Pro HSF on Volt-modded ASRock 775Dual-VSTA mobo (modded BIOS rev 3.10A and VNB=1.65, Vagp=1.8), 2x1GB Crucial Ballistix DDR2-800 RAM (3.0,3,3,8,1T @546MHz), Sapphire ATI HD3870 512MB GDDR4 PCIe graphics card overclocked to 850MHz GPU & 2.4GHz RAM. Powered by Hiper Type-M 580W PSU. Guess who likes overclocking on a budget.

Hmmm, nice one slippy. Funny you should say that I find I get much better performance outa my 80 chip with loads of AA and low reses.

Ive been reading about DX10.1

I tell you, I'm sure the nutters that write this stuff just make it up as they go along. Ive broken my new years res and bout a new game,( No more Games For 2008 except gohst busters) I got x-box 360 port MotoGP'07 looks like it does DX10.1 perfect to me.

I think we should bring back stoneing to sort out way ward Hanns Christian Anderson fantasy style computer Journalism,
