GeForce GTX 1050 vs Radeon R5 M255

Intro

Compare all of that to the Radeon R5 M255, which has a core clock frequency of 940 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 TAUs, and 8 ROPs.

GeForce GTX 1050		54160 Mtexels/sec
Radeon R5 M255		18800 Mtexels/sec
	Difference: 35360 (188%)

Pixel Rate

The GeForce GTX 1050 should be a lot (approximately 476%) faster with regards to full screen anti-aliasing than the Radeon R5 M255, and also will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 1050		43328 Mpixels/sec
Radeon R5 M255		7520 Mpixels/sec
	Difference: 35808 (476%)

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 data (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
