GeForce GTX 1050 3GB vs Radeon R7 250X 2GB

Intro

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

Radeon R7 250X 2GB		95 Watts
	Difference: 20 Watts (27%)

Memory Bandwidth

In theory, the GeForce GTX 1050 3GB should be 19% faster than the Radeon R7 250X 2GB in general, because of its greater bandwidth. (explain)

GeForce GTX 1050 3GB		86016 MB/sec
Radeon R7 250X 2GB		72000 MB/sec
	Difference: 14016 (19%)

Texel Rate

The GeForce GTX 1050 3GB will be a lot (approximately 67%) better at anisotropic filtering than the Radeon R7 250X 2GB. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 26816 (67%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1050 3GB is a better choice, and very much so. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 17408 (109%)

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 max amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 reach the max fill rate.
