GeForce GTX 750 Ti vs Radeon R9 M280X

Intro

The GeForce GTX 750 Ti uses a 28 nm design. nVidia has clocked the core frequency at 1020 MHz. The GDDR5 RAM is set to run at a speed of 1350 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Compare all of that to the Radeon R9 M280X, which features a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1375 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti 60 Watts
Radeon R9 M280X 75 Watts
Difference: 15 Watts (25%)

Memory Bandwidth

As far as performance goes, the Radeon R9 M280X should theoretically be a small bit superior to the GeForce GTX 750 Ti overall. (explain)

Radeon R9 M280X 88000 MB/sec
GeForce GTX 750 Ti 86400 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon R9 M280X will be a lot (approximately 24%) faster with regards to anisotropic filtering than the GeForce GTX 750 Ti. (explain)

Radeon R9 M280X 50400 Mtexels/sec
GeForce GTX 750 Ti 40800 Mtexels/sec
Difference: 9600 (24%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 750 Ti is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 750 Ti 16320 Mpixels/sec
Radeon R9 M280X 14400 Mpixels/sec
Difference: 1920 (13%)

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 MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a 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 figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
