Well I have been testing the Command & Conquer3 demo on my X1900 XTX + X1950 XTX CrossFire Edition CrossFire setup at maxx details @ reso 1440x 900 x32 FSAA x14, AF x16HQ, Adaptive AA as HDR at max settings, so here the results:
I must say that Direcx9.0c still looks very demanding!
Just look at all that Motion Blur!
Thanx to 3dfx we have that technology in our modern graphics accelerators of today. 8)
The Crossfire setup handles this game in these insane settings without a problem and quite fluid gameplay as well, not bad for 2 R580 based cards, since that the R580 was designed back in Q4 2005, my X1900 XTX is a Rev.B 0552, it's from week 52 year 2005 but it was released Q1 2006.
Okay I must admit that the X1950 XTX CrossFire Edition has a R580+ GPU only difference is the 256Bit GDDR4, Bios chip as Cooler, for the rest it's very identical it's a Rev.B 0629 year 2006 week 29 which was released begin Q3 2006
The X1950 XTX as X1950 XTX CFE were designed to test the GDDR4 memory type with the 512Bit Ringbus memory controller of the R580 VPU, and this test kinda proved it's great success.
The X1950 XTX CFE combined with the X1900 XTX really makes a very powerfull 3D render unit, delivering a max memory bandwidth of 115,4 GB per sec, there by beating a single GeForce 8800 GTX, which only does 84,6 GB per sec max.
The more memory bandwidth the more fps and better gameplay with max FSAA +Adaptive AA + AFHQ + HDR settings at high reso's as what I kinda found out by using this combination in C&C3 as Flight Simulator X and that's kinda future proof for an old architechture like that of the R580.
I wonder how futureproof the R600 will be, since a single X2900 XTX will do 153,4 GB per sec while a single X2900 XT will deliver 143.2 GB per sec, also not too shabby.
My next step is a crossfire setup of 2 X2900 XTX cards
but that will be later this year
