GeForce GTX 480 vs Radeon RX 6500 XT

Intro

Compare those specifications to the Radeon RX 6500 XT, which has a clock frequency of 2200 MHz and a GDDR6 memory frequency of 2250 MHz. It also uses a 64-bit bus, and makes use of a 6 nm design. It features 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Texel Rate

The Radeon RX 6500 XT will be much (approximately 235%) more effective at AF than the GeForce GTX 480. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6500 XT is superior to the GeForce GTX 480, and very much so. (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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
