Radeon RX 480 vs Radeon RX 6700 XT

Intro

Compare those specifications to the Radeon RX 6700 XT, which uses a 7 nm design. AMD has set the core speed at 2321 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this particular model. It features 2560 SPUs as well as 160 TAUs and 64 Rasterization Operator Units.

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

Memory Bandwidth

As far as performance goes, the Radeon RX 6700 XT should theoretically be much better than the Radeon RX 480 overall. (explain)

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

Texel Rate

The Radeon RX 6700 XT should be a lot (about 130%) better at texture 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

The Radeon RX 6700 XT is quite a bit (more or less 314%) faster with regards to full screen anti-aliasing than the Radeon RX 480, and also should be capable of handling higher resolutions while still performing well. (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 (measured in megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 applied per second. This is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number 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 amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
