Radeon RX 460 2GB vs Radeon RX 6500 XT

Intro

Compare that to the Radeon RX 6500 XT, which uses a 6 nm design. AMD has clocked the core frequency at 2200 MHz. The GDDR6 RAM is set to run at a frequency of 2250 MHz on this particular card. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Radeon RX 460 2GB		112000 MB/sec
	Difference: 35456 (32%)

Texel Rate

The Radeon RX 6500 XT will be much (approximately 131%) more effective at AF than the Radeon RX 460 2GB. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 79760 (131%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6500 XT is a better choice, and very much so. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon RX 460 2GB		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 largest amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 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 applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at 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 the graphics 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 number of ROPs by the clock 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
