GeForce GTX 750 vs Radeon R9 M270X

Intro

The GeForce GTX 750 comes with a GPU core speed of 1020 MHz, and the 1024 MB of GDDR5 memory runs at 1250 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the Radeon R9 M270X, which comes with clock speeds of 725 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 is 11% quicker than the Radeon R9 M270X in general, due to its higher data rate. (explain)

GeForce GTX 750 80000 MB/sec
Radeon R9 M270X 72000 MB/sec
Difference: 8000 (11%)

Texel Rate

The GeForce GTX 750 is a little bit (about 13%) more effective at texture filtering than the Radeon R9 M270X. (explain)

GeForce GTX 750 32640 Mtexels/sec
Radeon R9 M270X 29000 Mtexels/sec
Difference: 3640 (13%)

Pixel Rate

The GeForce GTX 750 will be much (more or less 41%) more effective at anti-aliasing than the Radeon R9 M270X, and also capable of handling higher resolutions better. (explain)

GeForce GTX 750 16320 Mpixels/sec
Radeon R9 M270X 11600 Mpixels/sec
Difference: 4720 (41%)

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 max amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
