Radeon RX 5600 vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which has GPU core speed of 1700 MHz, and 16384 MB of GDDR6 RAM running at 2000 MHz through a 256-bit bus. It also features 3840 Stream Processors, 240 TAUs, and 96 Raster Operation Units.

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

In theory, the Radeon RX 6800 should perform quite a bit faster than the Radeon RX 5600 in general. (explain)

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

Texel Rate

The Radeon RX 6800 is a lot (more or less 132%) faster with regards to AF 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 lots of anti-aliasing is important to you, then the Radeon RX 6800 is a better choice, by a large margin. (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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most 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 Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
