Radeon RX 570 vs Radeon RX 5700 XT 50th Anniversary Edition

Intro

Compare all that to the Radeon RX 5700 XT 50th Anniversary Edition, which features GPU clock speed of 1680 MHz, and 8096 MB of GDDR6 memory set to run at 1750 MHz through a 256-bit bus. It also features 2560 Stream Processors, 160 Texture Address Units, and 64 ROPs.

Radeon RX 5700 XT 50th Anniversary Edition		235 Watts
	Difference: 85 Watts (57%)

Memory Bandwidth

In theory, the Radeon RX 5700 XT 50th Anniversary Edition will be 100% quicker than the Radeon RX 570 in general, due to its greater data rate. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
Radeon RX 570		229376 MB/sec
	Difference: 229376 (100%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition will be much (about 80%) better at texture filtering than the Radeon RX 570. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon RX 570		149504 Mtexels/sec
	Difference: 119296 (80%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 5700 XT 50th Anniversary Edition is the winner, and very much so. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 70144 (188%)

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 (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the 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 core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
