Radeon R9 M270X vs Radeon RX 5600

Intro

Compare that to the Radeon RX 5600, which features a GPU core clock speed of 1375 MHz, and 6144 MB of GDDR6 RAM running at 1500 MHz through a 192-bit bus. It also is made up of 2048 SPUs, 128 TAUs, and 64 ROPs.

Radeon R9 M270X		72000 MB/sec
	Difference: 222912 (310%)

Texel Rate

The Radeon RX 5600 should be a lot (more or less 507%) better at anisotropic filtering than the Radeon R9 M270X. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 147000 (507%)

Pixel Rate

The Radeon RX 5600 is a lot (approximately 659%) better at full screen anti-aliasing than the Radeon R9 M270X, and capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 76400 (659%)

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 data (measured in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are 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 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 the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
