GeForce GTX 750 Ti vs Radeon R9 M270X

Intro

The GeForce GTX 750 Ti uses a 28 nm design. nVidia has clocked the core speed at 1020 MHz. The GDDR5 memory is set to run at a frequency of 1350 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the Radeon R9 M270X, which features clock speeds of 725 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 Ti is 20% faster than the Radeon R9 M270X overall, due to its greater bandwidth. (explain)

GeForce GTX 750 Ti 86400 MB/sec
Radeon R9 M270X 72000 MB/sec
Difference: 14400 (20%)

Texel Rate

The GeForce GTX 750 Ti should be quite a bit (about 41%) better at AF than the Radeon R9 M270X. (explain)

GeForce GTX 750 Ti 40800 Mtexels/sec
Radeon R9 M270X 29000 Mtexels/sec
Difference: 11800 (41%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 750 Ti is the winner, and very much so. (explain)

GeForce GTX 750 Ti 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 information (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 can be processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
