Radeon R9 270X		179200 MB/sec
	Difference: 164864 (92%)

Texel Rate

The Radeon RX 5600 XT is quite a bit (about 148%) faster with regards to anisotropic filtering than the Radeon R9 270X. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon R9 270X		80000 Mtexels/sec
	Difference: 118000 (148%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5600 XT is the winner, by far. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon R9 270X		32000 Mpixels/sec
	Difference: 56000 (175%)

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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units 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 also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
