Radeon RX 460 vs Radeon RX 5700 XT

Intro

Compare all that to the Radeon RX 5700 XT, which comes with a GPU core clock speed of 1605 MHz, and 8096 MB of GDDR6 memory running at 1750 MHz through a 256-bit bus. It also is comprised of 2560 Stream Processors, 160 Texture Address Units, and 64 ROPs.

Radeon RX 460		75 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 150 Watts (200%)

Memory Bandwidth

The Radeon RX 5700 XT should in theory perform much faster than the Radeon RX 460 in general. (explain)

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

Texel Rate

The Radeon RX 5700 XT should be much (more or less 321%) more effective at 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 running with a high screen resolution is important to you, then the Radeon RX 5700 XT is the winner, and very much so. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
