Radeon RX 480 vs Radeon RX 6650 XT

Intro

Compare all of that to the Radeon RX 6650 XT, which features a clock speed of 2055 MHz and a GDDR6 memory frequency of 2190 MHz. It also uses a 128-bit memory bus, and uses a 7 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 480		150 Watts
Radeon RX 6650 XT		176 Watts
	Difference: 26 Watts (17%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6650 XT is 10% faster than the Radeon RX 480 in general, due to its higher data rate. (explain)

Radeon RX 6650 XT		287072 MB/sec
Radeon RX 480		262144 MB/sec
	Difference: 24928 (10%)

Texel Rate

The Radeon RX 6650 XT should be quite a bit (about 63%) faster with regards to anisotropic filtering than the Radeon RX 480. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
Radeon RX 480		161280 Mtexels/sec
	Difference: 101760 (63%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6650 XT is the winner, by a large margin. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 95680 (267%)

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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 most pixels that the graphics card could 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 clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
