Radeon R9 270 vs Radeon RX 5600 XT

Intro

Compare all of that to the Radeon RX 5600 XT, which uses a 7 nm design. AMD has set the core speed at 1375 MHz. The GDDR6 RAM runs at a speed of 1500 MHz on this particular model. It features 2304 SPUs along with 144 TAUs and 64 Rasterization Operator Units.

Memory Bandwidth

As far as performance goes, the Radeon RX 5600 XT should in theory be quite a bit better than the Radeon R9 270 in general. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon R9 270		179200 MB/sec
	Difference: 164864 (92%)

Texel Rate

The Radeon RX 5600 XT will be much (more or less 175%) faster with regards to AF than the Radeon R9 270. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon R9 270		72000 Mtexels/sec
	Difference: 126000 (175%)

Pixel Rate

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

Radeon RX 5600 XT		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 maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount 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 amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
