Radeon RX 5700 vs Radeon RX 6800 XT

Intro

Compare that to the Radeon RX 6800 XT, which uses a 7 nm design. AMD has clocked the core speed at 1825 MHz. The GDDR6 RAM runs at a frequency of 2000 MHz on this specific model. It features 4608 SPUs along with 288 TAUs and 128 Rasterization Operator Units.

Texel Rate

The Radeon RX 6800 XT will be much (more or less 149%) more effective at anisotropic filtering than the Radeon RX 5700. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 314640 (149%)

Pixel Rate

The Radeon RX 6800 XT will be quite a bit (approximately 149%) faster with regards to anti-aliasing than the Radeon RX 5700, and also capable of handling higher screen resolutions better. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 139840 (149%)

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 information (counted in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels 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 ROPs by the the card's clock speed. 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
