GeForce GTX 560 vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which uses a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 RAM works at a speed of 1125 MHz on this model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 should be 78% quicker than the Radeon R9 M365X in general, due to its higher data rate. (explain)

GeForce GTX 560		128128 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 56128 (78%)

Texel Rate

The GeForce GTX 560 will be quite a bit (approximately 23%) more effective at texture filtering than the Radeon R9 M365X. (explain)

GeForce GTX 560		45360 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 8360 (23%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 560 is superior to the Radeon R9 M365X, and very much so. (explain)

GeForce GTX 560		25920 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 11120 (75%)

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 maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
