GeForce GTX 750 vs Radeon R7 250X 2GB

Intro

The GeForce GTX 750 features core clock speeds of 1020 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

Compare those specifications to the Radeon R7 250X 2GB, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory works at a speed of 1125 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 55 Watts
Radeon R7 250X 2GB 95 Watts
Difference: 40 Watts (73%)

Memory Bandwidth

In theory, the GeForce GTX 750 will be 11% faster than the Radeon R7 250X 2GB in general, because of its greater bandwidth. (explain)

GeForce GTX 750 80000 MB/sec
Radeon R7 250X 2GB 72000 MB/sec
Difference: 8000 (11%)

Texel Rate

The Radeon R7 250X 2GB will be a lot (about 23%) faster with regards to anisotropic filtering than the GeForce GTX 750. (explain)

Radeon R7 250X 2GB 40000 Mtexels/sec
GeForce GTX 750 32640 Mtexels/sec
Difference: 7360 (23%)

Pixel Rate

The GeForce GTX 750 should be just a bit (approximately 2%) better at FSAA than the Radeon R7 250X 2GB, and able to handle higher resolutions better. (explain)

GeForce GTX 750 16320 Mpixels/sec
Radeon R7 250X 2GB 16000 Mpixels/sec
Difference: 320 (2%)

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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
