GeForce GTX 750 Ti vs Radeon R9 M270X

Intro

The GeForce GTX 750 Ti has a GPU clock speed of 1020 MHz, and the 2048 MB of GDDR5 memory is set to run at 1350 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Compare that 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 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 750 Ti should in theory be a little bit faster than the Radeon R9 M270X in general. (explain)

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

Texel Rate

The GeForce GTX 750 Ti is quite a bit (more or less 41%) more effective at anisotropic filtering than the Radeon R9 M270X. (explain)

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

Pixel Rate

The GeForce GTX 750 Ti will be a lot (approximately 41%) better at AA than the Radeon R9 M270X, and also should be able to handle higher resolutions more effectively. (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 largest amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
