GeForce GTX 570 vs Radeon R9 M280X

Intro

Compare those specs to the Radeon R9 M280X, which uses a 28 nm design. AMD has clocked the core frequency at 900 MHz. The GDDR5 RAM runs at a speed of 1375 MHz on this particular card. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Radeon R9 M280X		88000 MB/sec
	Difference: 64000 (73%)

Texel Rate

The Radeon R9 M280X will be a small bit (more or less 15%) more effective at texture filtering than the GeForce GTX 570. (explain)

Radeon R9 M280X		50400 Mtexels/sec
GeForce GTX 570		43920 Mtexels/sec
	Difference: 6480 (15%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 570 is a better choice, and very much so. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon R9 M280X		14400 Mpixels/sec
	Difference: 14880 (103%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to 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 ability to get to the maximum fill rate.
