Radeon R5 M255 vs Radeon RX 5600

Intro

The Radeon R5 M255 makes use of a 28 nm design. AMD has set the core speed at 940 MHz. The DDR3 memory works at a frequency of 1000 MHz on this specific card. It features 320 SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Compare those specs to the Radeon RX 5600, which has GPU core speed of 1375 MHz, and 6144 MB of GDDR6 memory set to run at 1500 MHz through a 192-bit bus. It also features 2048 Stream Processors, 128 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 should perform quite a bit faster than the Radeon R5 M255 in general. (explain)

Radeon RX 5600 294912 MB/sec
Radeon R5 M255 16000 MB/sec
Difference: 278912 (1743%)

Texel Rate

The Radeon RX 5600 should be a lot (more or less 836%) better at anisotropic filtering than the Radeon R5 M255. (explain)

Radeon RX 5600 176000 Mtexels/sec
Radeon R5 M255 18800 Mtexels/sec
Difference: 157200 (836%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 5600 is the winner, by far. (explain)

Radeon RX 5600 88000 Mpixels/sec
Radeon R5 M255 7520 Mpixels/sec
Difference: 80480 (1070%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
