Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 5600 should theoretically be quite a bit faster than the Radeon R9 270 overall. (explain)

Radeon RX 5600		294912 MB/sec
Radeon R9 270		179200 MB/sec
	Difference: 115712 (65%)

Texel Rate

The Radeon RX 5600 is a lot (approximately 144%) faster with regards to anisotropic filtering than the Radeon R9 270. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon R9 270		72000 Mtexels/sec
	Difference: 104000 (144%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 5600 is superior to the Radeon R9 270, by a large margin. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon R9 270		28800 Mpixels/sec
	Difference: 59200 (206%)

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 largest amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the 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 number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock 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 also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
