Geforce GTX 760 vs Radeon R9 M265X

Intro

Compare those specifications to the Radeon R9 M265X, which comes with core clock speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Geforce GTX 760 should perform quite a bit faster than the Radeon R9 M265X overall. (explain)

Geforce GTX 760		192256 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 120256 (167%)

Texel Rate

The Geforce GTX 760 should be a lot (approximately 309%) more effective at anisotropic filtering than the Radeon R9 M265X. (explain)

Geforce GTX 760		94080 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 71080 (309%)

Pixel Rate

If running with a high resolution is important to you, then the Geforce GTX 760 is the winner, by a large margin. (explain)

Geforce GTX 760		31360 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 22160 (241%)

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 information (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video 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 amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. 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 lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
