Radeon RX 570 vs Radeon RX 5700 XT

Intro

Compare that to the Radeon RX 5700 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1605 MHz. The GDDR6 memory is set to run at a frequency of 1750 MHz on this particular card. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Radeon RX 570		229376 MB/sec
	Difference: 229376 (100%)

Texel Rate

The Radeon RX 5700 XT will be a lot (about 72%) more effective at anisotropic filtering than the Radeon RX 570. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon RX 570		149504 Mtexels/sec
	Difference: 107296 (72%)

Pixel Rate

The Radeon RX 5700 XT will be quite a bit (about 175%) faster with regards to AA than the Radeon RX 570, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 65344 (175%)

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 maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
