GeForce GTX 570 vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which comes with a clock frequency of 1015 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 570 should in theory be quite a bit superior to the Radeon R9 M375X in general. (explain)

GeForce GTX 570		152000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 80000 (111%)

Texel Rate

The GeForce GTX 570 will be a small bit (approximately 8%) more effective at AF than the Radeon R9 M375X. (explain)

GeForce GTX 570		43920 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 3320 (8%)

Pixel Rate

The GeForce GTX 570 will be much (about 80%) better at full screen anti-aliasing than the Radeon R9 M375X, and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 13040 (80%)

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 information (measured in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number 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 graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
