GeForce GTX 570 vs Radeon R9 M375X

Intro

Compare that to the Radeon R9 M375X, which features a core clock frequency of 1015 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is comprised 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 theoretically be a lot 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 (about 8%) faster with regards to anisotropic filtering than the Radeon R9 M375X. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 570 is a better choice, by far. (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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 can be applied in one second. This is worked out by multiplying the total texture units of the card 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
