Radeon R5 M255 vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which has a core clock speed of 1375 MHz and a GDDR6 memory speed of 1500 MHz. It also features a 192-bit bus, and uses a 7 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 5600 should be 1743% faster than the Radeon R5 M255 overall, because of its greater data rate. (explain)

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

Texel Rate

The Radeon RX 5600 is quite a bit (approximately 836%) more effective at texture filtering than the Radeon R5 M255. (explain)

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

Pixel Rate

The Radeon RX 5600 will be quite a bit (approximately 1070%) more effective at AA than the Radeon R5 M255, and will be capable of handling higher resolutions without losing too much performance. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
