Radeon RX 460 vs Radeon RX 6500 XT

Intro

Compare that to the Radeon RX 6500 XT, which makes use of a 6 nm design. AMD has clocked the core speed at 2200 MHz. The GDDR6 memory runs at a speed of 2250 MHz on this particular card. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Radeon RX 460		112000 MB/sec
	Difference: 35456 (32%)

Texel Rate

The Radeon RX 6500 XT will be a lot (about 131%) faster with regards to anisotropic filtering than the Radeon RX 460. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon RX 460		61040 Mtexels/sec
	Difference: 79760 (131%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6500 XT is the winner, by far. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 52960 (304%)

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 max amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
