Radeon RX 480 4GB vs Radeon RX 6700 XT

Intro

Compare that to the Radeon RX 6700 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 2321 MHz. The GDDR6 RAM is set to run at a frequency of 2000 MHz on this particular card. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.

Radeon RX 480 4GB		229376 MB/sec
	Difference: 163840 (71%)

Texel Rate

The Radeon RX 6700 XT is a lot (more or less 130%) better at AF than the Radeon RX 480 4GB. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 210080 (130%)

Pixel Rate

The Radeon RX 6700 XT will be quite a bit (about 314%) faster with regards to full screen anti-aliasing than the Radeon RX 480 4GB, and will be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon RX 480 4GB		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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines 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 fill rate also depends 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 maximum fill rate.
