GeForce GTX 480 vs Radeon RX 6500 XT

Intro

Compare all that to the Radeon RX 6500 XT, which has a GPU core clock speed of 2200 MHz, and 4096 MB of GDDR6 RAM set to run at 2250 MHz through a 64-bit bus. It also is made up of 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Radeon RX 6500 XT		147456 MB/sec
	Difference: 29952 (20%)

Texel Rate

The Radeon RX 6500 XT is much (about 235%) faster with regards to anisotropic filtering than the GeForce GTX 480. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 98800 (235%)

Pixel Rate

The Radeon RX 6500 XT should be a lot (about 110%) more effective at AA than the GeForce GTX 480, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 480		33600 Mpixels/sec
	Difference: 36800 (110%)

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 moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
