GeForce 9800 GTX+ vs GeForce GTX 570

Intro

The GeForce 9800 GTX+ makes use of a 55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 memory works at a frequency of 1100 MHz on this specific card. It features 128 SPUs along with 64 TAUs and 16 ROPs.

Compare those specifications to the GeForce GTX 570, which has core speeds of 732 MHz on the GPU, and 950 MHz on the 1280 MB of GDDR5 RAM. It features 480 SPUs as well as 60 TAUs and 40 ROPs.

The GeForce 9800 GTX+ is a little bit (more or less 8%) more effective at texture filtering than the GeForce GTX 570. (explain)

GeForce 9800 GTX+ 47232 Mtexels/sec
GeForce GTX 570 43920 Mtexels/sec
Difference: 3312 (8%)

Pixel Rate

The GeForce GTX 570 should be a lot (approximately 148%) more effective at full screen anti-aliasing than the GeForce 9800 GTX+, and also able to handle higher screen resolutions better. (explain)

GeForce GTX 570 29280 Mpixels/sec
GeForce 9800 GTX+ 11808 Mpixels/sec
Difference: 17472 (148%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
