GeForce GTX 1050 vs Radeon R5 M255

Intro

Compare all of that to the Radeon R5 M255, which makes use of a 28 nm design. AMD has clocked the core frequency at 940 MHz. The DDR3 memory works at a speed of 1000 MHz on this card. It features 320 SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 1050 should in theory perform much faster than the Radeon R5 M255 overall. (explain)

GeForce GTX 1050		114688 MB/sec
Radeon R5 M255		16000 MB/sec
	Difference: 98688 (617%)

Texel Rate

The GeForce GTX 1050 will be a lot (approximately 188%) more effective at AF than the Radeon R5 M255. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 1050 is superior to the Radeon R5 M255, and very much so. (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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 applied in one second. This figure is worked out 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
