Radeon RX 5600 vs Radeon RX 6650 XT

Intro

The Radeon RX 5600 uses a 7 nm design. AMD has set the core frequency at 1375 MHz. The GDDR6 memory is set to run at a frequency of 1500 MHz on this specific card. It features 2048 SPUs along with 128 TAUs and 64 Rasterization Operator Units.

Compare those specifications to the Radeon RX 6650 XT, which features a GPU core clock speed of 2055 MHz, and 8192 MB of GDDR6 memory running at 2190 MHz through a 128-bit bus. It also is comprised of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

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

Texel Rate

The Radeon RX 6650 XT will be a lot (about 49%) better at 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 quite a bit (more or less 49%) more effective at anti-aliasing than the Radeon RX 5600, and also should be capable of handling higher resolutions better. (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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
