Radeon RX 480 vs Radeon RX 6650 XT

Intro

The Radeon RX 480 comes with clock speeds of 1120 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2304 SPUs along with 144 Texture Address Units and 32 Rasterization Operator Units.

Compare that to the Radeon RX 6650 XT, which features GPU core speed of 2055 MHz, and 8192 MB of GDDR6 RAM set to run at 2190 MHz through a 128-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 64 Raster Operation Units.

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

Texel Rate

The Radeon RX 6650 XT will be a lot (about 63%) more effective at 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

The Radeon RX 6650 XT should be quite a bit (about 267%) better at full screen anti-aliasing than the Radeon RX 480, and also will be capable of handling higher screen resolutions without slowing down too much. (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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
