GeForce GTX 750 vs Radeon R7 250X 2GB

Intro

Compare all of that to the Radeon R7 250X 2GB, which comes with a core clock frequency of 1000 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

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

The GeForce GTX 750, in theory, should perform a small bit faster than the Radeon R7 250X 2GB in general. (explain)

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

Texel Rate

The Radeon R7 250X 2GB is a lot (approximately 23%) better at AF than the GeForce GTX 750. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 750 is the winner, but it probably won't make a huge difference. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
