GeForce GTX 1050 vs Radeon R9 M390X

Intro

Compare all of that to the Radeon R9 M390X, which makes use of a 28 nm design. AMD has clocked the core speed at 723 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this specific card. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 1050		54160 Mtexels/sec
	Difference: 38384 (71%)

Pixel Rate

The GeForce GTX 1050 is quite a bit (about 87%) better at AA than the Radeon R9 M390X, and will be able to handle higher screen resolutions better. (explain)

GeForce GTX 1050		43328 Mpixels/sec
Radeon R9 M390X		23136 Mpixels/sec
	Difference: 20192 (87%)

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 (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
