Radeon RX 5500 XT vs Radeon RX 6750 XT

Intro

Compare all of that to the Radeon RX 6750 XT, which comes with clock speeds of 2150 MHz on the GPU, and 2250 MHz on the 12288 MB of GDDR6 memory. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Radeon RX 5500 XT		130 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 120 Watts (92%)

Memory Bandwidth

In theory, the Radeon RX 6750 XT is 93% faster than the Radeon RX 5500 XT in general, due to its greater data rate. (explain)

Radeon RX 6750 XT		442368 MB/sec
Radeon RX 5500 XT		229376 MB/sec
	Difference: 212992 (93%)

Texel Rate

The Radeon RX 6750 XT will be a lot (more or less 128%) more effective at texture filtering than the Radeon RX 5500 XT. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 192904 (128%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6750 XT is the winner, by a large margin. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 82656 (150%)

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 largest amount of information (in units of MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
