Radeon R9 270 vs Radeon RX 5600

Intro

Compare those specifications to the Radeon RX 5600, which has a clock frequency of 1375 MHz and a GDDR6 memory frequency of 1500 MHz. It also makes use of a 192-bit memory bus, and uses a 7 nm design. It features 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 will be 65% faster than the Radeon R9 270 in general, due to its higher data rate. (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%) more effective at texture filtering than the Radeon R9 270. (explain)

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

Pixel Rate

The Radeon RX 5600 should be much (approximately 206%) faster with regards to anti-aliasing than the Radeon R9 270, and also able to handle higher screen resolutions better. (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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated 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 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 that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
