Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 570 should be 111% faster than the Radeon R9 M365X in general, because of its higher data rate. (explain)

GeForce GTX 570		152000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 80000 (111%)

Texel Rate

The GeForce GTX 570 will be a bit (approximately 19%) better at texture filtering than the Radeon R9 M365X. (explain)

GeForce GTX 570		43920 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 6920 (19%)

Pixel Rate

The GeForce GTX 570 should be a lot (about 98%) faster with regards to FSAA than the Radeon R9 M365X, and should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 14480 (98%)

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 max amount of information (in units of MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant 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.
