GeForce GTX 1050 3GB vs Radeon R5 M255

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1050 3GB will be 438% quicker than the Radeon R5 M255 in general, because of its higher data rate. (explain)

GeForce GTX 1050 3GB		86016 MB/sec
Radeon R5 M255		16000 MB/sec
	Difference: 70016 (438%)

Texel Rate

The GeForce GTX 1050 3GB will be much (approximately 255%) faster with regards to AF than the Radeon R5 M255. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
Radeon R5 M255		18800 Mtexels/sec
	Difference: 48016 (255%)

Pixel Rate

The GeForce GTX 1050 3GB should be quite a bit (more or less 344%) more effective at AA than the Radeon R5 M255, and also will be capable of handling higher screen resolutions better. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Radeon R5 M255		7520 Mpixels/sec
	Difference: 25888 (344%)

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 largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
