Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250		65 Watts
GeForce GTX 1050 3GB		75 Watts
	Difference: 10 Watts (15%)

Memory Bandwidth

In theory, the GeForce GTX 1050 3GB should be 17% faster than the Radeon R7 250 overall, due to its higher bandwidth. (explain)

GeForce GTX 1050 3GB		86016 MB/sec
Radeon R7 250		73600 MB/sec
	Difference: 12416 (17%)

Texel Rate

The GeForce GTX 1050 3GB will be a lot (approximately 178%) better at AF than the Radeon R7 250. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 42816 (178%)

Pixel Rate

The GeForce GTX 1050 3GB should be quite a bit (more or less 318%) faster with regards to AA than the Radeon R7 250, and will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 25408 (318%)

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 maximum amount of information (measured in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
