GeForce GTX 750 vs Radeon R7 250X 2GB

Intro

Compare those specifications to the Radeon R7 250X 2GB, which has a core clock frequency of 1000 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation 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

Theoretically speaking, the GeForce GTX 750 should be just a 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 will be quite a bit (more or less 23%) more effective at texture 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

If using high levels of AA is important to you, then the GeForce GTX 750 is the winner, though only just barely. (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: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 are processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 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 speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
