Radeon RX 5500 XT vs Radeon RX 6800 XT

Intro

Compare those specifications to the Radeon RX 6800 XT, which uses a 7 nm design. AMD has set the core frequency at 1825 MHz. The GDDR6 RAM is set to run at a frequency of 2000 MHz on this particular card. It features 4608 SPUs as well as 288 TAUs and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Radeon RX 6800 XT		300 Watts
	Difference: 170 Watts (131%)

Memory Bandwidth

Performance-wise, the Radeon RX 6800 XT should in theory be quite a bit better than the Radeon RX 5500 XT in general. (explain)

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

Texel Rate

The Radeon RX 6800 XT is much (more or less 248%) faster with regards to AF than the Radeon RX 5500 XT. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 374504 (248%)

Pixel Rate

The Radeon RX 6800 XT should be quite a bit (approximately 325%) faster with regards to anti-aliasing than the Radeon RX 5500 XT, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 178656 (325%)

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 max amount of data (in units of MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. 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 is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
