Radeon RX 480 vs Radeon RX 6700 XT

Intro

Compare that to the Radeon RX 6700 XT, which comes with a GPU core clock speed of 2321 MHz, and (Unknown) MB of GDDR6 memory running at 2000 MHz through a 192-bit bus. It also is comprised of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 480		150 Watts
Radeon RX 6700 XT		230 Watts
	Difference: 80 Watts (53%)

Memory Bandwidth

In theory, the Radeon RX 6700 XT should be 50% faster than the Radeon RX 480 in general, because of its greater bandwidth. (explain)

Radeon RX 6700 XT		393216 MB/sec
Radeon RX 480		262144 MB/sec
	Difference: 131072 (50%)

Texel Rate

The Radeon RX 6700 XT is much (approximately 130%) faster with regards to anisotropic filtering than the Radeon RX 480. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon RX 480		161280 Mtexels/sec
	Difference: 210080 (130%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6700 XT is the winner, by far. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 112704 (314%)

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 (in units of MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per 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 - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
