GeForce GTX 750 Ti vs Radeon R7 250X 2GB

Intro

Compare that to the Radeon R7 250X 2GB, which features core clock speeds of 1000 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Texel Rate

The GeForce GTX 750 Ti should be a small bit (about 2%) faster with regards to AF than the Radeon R7 250X 2GB. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 800 (2%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 750 Ti is the winner, though only just barely. (explain)

GeForce GTX 750 Ti		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 information (in units of MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 are processed per second. This number is calculated by multiplying the total texture units of the card 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 in a second.

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