Radeon RX 5700 vs Radeon RX 6750 XT

Intro

Compare those specifications to the Radeon RX 6750 XT, which has a GPU core clock speed of 2150 MHz, and 12288 MB of GDDR6 memory set to run at 2250 MHz through a 192-bit bus. It also is comprised of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Radeon RX 6750 XT		442368 MB/sec
	Difference: 16384 (4%)

Texel Rate

The Radeon RX 6750 XT should be quite a bit (more or less 63%) more effective at anisotropic filtering than the Radeon RX 5700. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 133040 (63%)

Pixel Rate

The Radeon RX 6750 XT will be much (more or less 47%) more effective at AA than the Radeon RX 5700, and also should be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 43840 (47%)

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 (measured in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
