Radeon RX 5600 vs Radeon RX 6650 XT

Intro

Compare those specifications to the Radeon RX 6650 XT, which comes with core speeds of 2055 MHz on the GPU, and 2190 MHz on the 8192 MB of GDDR6 memory. It features 2048 SPUs along with 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The Radeon RX 5600, in theory, should perform just a bit faster than the Radeon RX 6650 XT overall. (explain)

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

Texel Rate

The Radeon RX 6650 XT should be quite a bit (approximately 49%) more effective 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

If running with a high resolution is important to you, then the Radeon RX 6650 XT is the winner, and very much so. (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 max amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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.
