Rsx

[ihamoitc2005]

I wonder what PC card is like RSX. Is it like 7600GT? This card has good performance with FEAR and many features like HDMI. Maybe I am "off-base".

RSX is custom, it's performance is between 7600 GT and 7800 GTX on it's own. developers will get more out of it because it's in a closed box, fixed environment and Cell will be used to assist RSX, and help minimize RSX's weaknesses like triangle setup.

i would say its much closer to a 7800 GTX, possibly even better. i would say its closest to a 7800 GTX 512MB or 7900 GT.

I think you mean 7800GTX 512. The 7800GTX has a 14% lower clock rate than RSX, AFAIK, so you'll certainly find cases where RSX beats the 7800GTX. But yeah, in some tasks you could be as slow as a 7600GT.

It is G70 based @ 500MHz. To contrast the 7800GTX 512MB was 550MHz and the 7800GTX was 430MHz. It has the same general architecture as G70 and has 24 G70-Pixel Shaders, 8 Vertex Shaders, and 24 TMUs. Where it departs from the 7800 series is that it only has 8 ROPs, like the 7600GT. This is due to the framebuffer bandwidth (GDDR3 650MHz, ~20GB/s) being less than half of a 7800GTX 512MB (which was about, or over, 50GB/s if I remember correctly). The 7600GT with 8 ROPs is more than sufficient for the bandwidth available, so any extra ROPs would be useless in most situations. RSX also has some cache adjustments and general tweaks as well. It also has access to XDR for texturing and the FlexIO bus to Cell.

So the answer to your question is "it depends". In ROP or framebuffer limited scenarios it is more like a 7600GT; in most others it is like a G70 @ 500MHz. But in reality it is in a closed box and can be utilized and designed around to get better performance than you would see on the PC with a general API and games designed to work on a wide array of hardware.

Cell can also assist RSX, so you really can't compare it to a PC video card.
