Radeon RX 5600 vs Radeon RX 6650 XT

Intro

Compare all that to the Radeon RX 6650 XT, which has GPU core speed of 2055 MHz, and 8192 MB of GDDR6 memory running at 2190 MHz through a 128-bit bus. It also is made up of 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Radeon RX 5600		150 Watts
Radeon RX 6650 XT		176 Watts
	Difference: 26 Watts (17%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 should be 3% faster than the Radeon RX 6650 XT in general, because of its higher data rate. (explain)

Radeon RX 5600		294912 MB/sec
Radeon RX 6650 XT		287072 MB/sec
	Difference: 7840 (3%)

Texel Rate

The Radeon RX 6650 XT will be a lot (more or less 49%) faster with regards to anisotropic filtering than the Radeon RX 5600. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
Radeon RX 5600		176000 Mtexels/sec
	Difference: 87040 (49%)

Pixel Rate

The Radeon RX 6650 XT is a lot (about 49%) better at anti-aliasing than the Radeon RX 5600, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Radeon RX 5600		88000 Mpixels/sec
	Difference: 43520 (49%)

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 (counted in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
