GeForce GTX 280 vs GeForce GTX 570

Intro

The GeForce GTX 280 has a core clock speed of 602 MHz and a GDDR3 memory frequency of 1107 MHz. It also uses a 512-bit bus, and makes use of a 65 nm design. It features 240 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Compare those specs to the GeForce GTX 570, which comes with GPU clock speed of 732 MHz, and 1280 MB of GDDR5 memory set to run at 950 MHz through a 320-bit bus. It also is comprised of 480 SPUs, 60 TAUs, and 40 Raster Operation Units.

GeForce GTX 280 141696 MB/sec
Difference: 10304 (7%)

Texel Rate

The GeForce GTX 280 should be just a bit (about 10%) more effective at texture filtering than the GeForce GTX 570. (explain)

GeForce GTX 280 48160 Mtexels/sec
GeForce GTX 570 43920 Mtexels/sec
Difference: 4240 (10%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 570 is a better choice, by a large margin. (explain)

GeForce GTX 570 29280 Mpixels/sec
GeForce GTX 280 19264 Mpixels/sec
Difference: 10016 (52%)

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 data (counted in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
