Radeon RX 590 vs Radeon RX 6650 XT

Intro

Compare all of that to the Radeon RX 6650 XT, which features clock speeds of 2055 MHz on the GPU, and 2190 MHz on the 8192 MB of GDDR6 RAM. It features 2048 SPUs as well as 128 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590		175 Watts
Radeon RX 6650 XT		176 Watts
	Difference: 1 Watts (1%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6650 XT will be 10% quicker than the Radeon RX 590 overall, due to its greater bandwidth. (explain)

Radeon RX 6650 XT		287072 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 24928 (10%)

Texel Rate

The Radeon RX 6650 XT should be quite a bit (approximately 24%) more effective at texture filtering than the Radeon RX 590. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
Radeon RX 590		211536 Mtexels/sec
	Difference: 51504 (24%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6650 XT is a better choice, by far. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 84512 (180%)

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 (measured in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
