Radeon RX 480 vs Radeon RX 6650 XT

Intro

Compare that to the Radeon RX 6650 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 2055 MHz. The GDDR6 RAM works at a frequency of 2190 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

Memory Bandwidth

As far as performance goes, the Radeon RX 6650 XT should in theory be a little bit better than the Radeon RX 480 in general. (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 (more or less 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 using a high screen resolution 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 data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
