GeForce GTX 750 vs Radeon R9 280X

Intro

The GeForce GTX 750 comes with a GPU clock speed of 1020 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1250 MHz through a 128-bit bus. It also features 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare that to the Radeon R9 280X, which makes use of a 28 nm design. AMD has set the core speed at 850 MHz. The GDDR5 memory is set to run at a speed of 1500 MHz on this particular card. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

GeForce GTX 750 80000 MB/sec
Difference: 208000 (260%)

Texel Rate

The Radeon R9 280X is quite a bit (about 233%) more effective at texture filtering than the GeForce GTX 750. (explain)

Radeon R9 280X 108800 Mtexels/sec
GeForce GTX 750 32640 Mtexels/sec
Difference: 76160 (233%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 280X is superior to the GeForce GTX 750, and very much so. (explain)

Radeon R9 280X 27200 Mpixels/sec
GeForce GTX 750 16320 Mpixels/sec
Difference: 10880 (67%)

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 (counted in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could 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 Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
