Radeon RX 5600 vs Radeon RX 6900 XT

Intro

Compare all that to the Radeon RX 6900 XT, which features GPU clock speed of 1825 MHz, and 16384 MB of GDDR6 RAM running at 2000 MHz through a 256-bit bus. It also features 5120 Stream Processors, 320 TAUs, and 128 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600		150 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 150 Watts (100%)

Memory Bandwidth

In theory, the Radeon RX 6900 XT will be 78% quicker than the Radeon RX 5600 in general, due to its greater bandwidth. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon RX 5600		294912 MB/sec
	Difference: 229376 (78%)

Texel Rate

The Radeon RX 6900 XT should be quite a bit (approximately 232%) better at anisotropic filtering than the Radeon RX 5600. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon RX 5600		176000 Mtexels/sec
	Difference: 408000 (232%)

Pixel Rate

The Radeon RX 6900 XT is a lot (more or less 165%) faster with regards to FSAA than the Radeon RX 5600, and also will be able to handle higher resolutions more effectively. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon RX 5600		88000 Mpixels/sec
	Difference: 145600 (165%)

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 maximum amount of information (counted in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
