GeForce GTX 750 vs Radeon R9 M265X

Intro

The GeForce GTX 750 comes with a clock frequency of 1020 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is made up of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare all of that to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has set the core speed at 575 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this specific 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 750 should be just a bit faster than the Radeon R9 M265X in general. (explain)

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

Texel Rate

The GeForce GTX 750 is much (about 42%) better at texture filtering than the Radeon R9 M265X. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 750 is a better choice, by a large margin. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 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 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
