Radeon RX 5600 vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which features a clock speed of 1700 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 7 nm design. It is made up of 3840 SPUs, 240 Texture Address Units, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600		150 Watts
Radeon RX 6800		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

The Radeon RX 6800, in theory, should be much faster than the Radeon RX 5600 overall. (explain)

Radeon RX 6800		524288 MB/sec
Radeon RX 5600		294912 MB/sec
	Difference: 229376 (78%)

Texel Rate

The Radeon RX 6800 will be quite a bit (about 132%) more effective at texture filtering than the Radeon RX 5600. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon RX 5600		176000 Mtexels/sec
	Difference: 232000 (132%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6800 is the winner, and very much so. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon RX 5600		88000 Mpixels/sec
	Difference: 75200 (85%)

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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it 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 per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels 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 amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
