GeForce GTX 570 vs Radeon R9 M365X

Intro

Compare those specs to the Radeon R9 M365X, which comes with core clock speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 570 should be 111% quicker than the Radeon R9 M365X overall, because of its greater bandwidth. (explain)

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

Texel Rate

The GeForce GTX 570 should be a small bit (about 19%) more effective at anisotropic filtering than the Radeon R9 M365X. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 570 is the winner, by a large margin. (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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher 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 most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
