Radeon R9 270 vs Radeon RX 5600

Intro

Compare those specifications 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 memory bus, and makes use of a 7 nm design. It is made up of 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 5600 should in theory 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 should be quite a bit (approximately 144%) more effective at 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

The Radeon RX 5600 is much (more or less 206%) faster with regards to FSAA than the Radeon R9 270, and will be capable of handling higher resolutions more effectively. (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 max amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video 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 most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. 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 bandwidth is, the lower the ability to reach the max fill rate.
