Radeon RX 5500 XT vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which makes use of a 7 nm design. AMD has clocked the core speed at 1700 MHz. The GDDR6 memory works at a frequency of 2000 MHz on this specific card. It features 3840 SPUs as well as 240 TAUs and 96 Rasterization Operator Units.

Radeon RX 6800		250 Watts
	Difference: 120 Watts (92%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6800 should in theory be much superior to the Radeon RX 5500 XT overall. (explain)

Radeon RX 6800		524288 MB/sec
Radeon RX 5500 XT		229376 MB/sec
	Difference: 294912 (129%)

Texel Rate

The Radeon RX 6800 is quite a bit (about 170%) better at anisotropic filtering than the Radeon RX 5500 XT. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 256904 (170%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6800 is the winner, by far. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 108256 (197%)

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 largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
