Radeon RX 460 vs Radeon RX 5700 XT

Intro

The Radeon RX 460 has a GPU clock speed of 1090 MHz, and the 4096 MB of GDDR5 memory is set to run at 1750 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Compare those specs to the Radeon RX 5700 XT, which features a GPU core clock speed of 1605 MHz, and 8096 MB of GDDR6 RAM set to run at 14000 MHz through a 256-bit bus. It also is made up of 2560 Stream Processors, 160 Texture Address Units, and 64 ROPs.

Radeon RX 5700 XT 458752 MB/sec
Radeon RX 460 112000 MB/sec
Difference: 346752 (310%)

Texel Rate

The Radeon RX 5700 XT is much (approximately 321%) faster with regards to anisotropic filtering than the Radeon RX 460. (explain)

Radeon RX 5700 XT 256800 Mtexels/sec
Radeon RX 460 61040 Mtexels/sec
Difference: 195760 (321%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 5700 XT is a better choice, by far. (explain)

Radeon RX 5700 XT 102720 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 85280 (489%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one 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 drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
