GeForce GTX 750 vs Radeon R9 M265X

Intro

Compare that to the Radeon R9 M265X, which has core clock speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 750 should perform a bit faster than the Radeon R9 M265X overall. (explain)

GeForce GTX 750		80000 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 8000 (11%)

Texel Rate

The GeForce GTX 750 will be much (more or less 42%) better at anisotropic filtering than the Radeon R9 M265X. (explain)

GeForce GTX 750		32640 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 9640 (42%)

Pixel Rate

The GeForce GTX 750 should be much (more or less 77%) more effective at AA than the Radeon R9 M265X, and also should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 750		16320 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 7120 (77%)

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 information (counted in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
