Radeon RX 460 2GB vs Radeon RX 6800

Intro

Compare all of that to the Radeon RX 6800, which comes with a clock speed of 1700 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 256-bit bus, and uses a 7 nm design. It is made up of 3840 SPUs, 240 TAUs, and 96 Raster Operation Units.

The Radeon RX 6800 is quite a bit (approximately 568%) more effective at anisotropic filtering than the Radeon RX 460 2GB. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 346960 (568%)

Pixel Rate

The Radeon RX 6800 should be quite a bit (more or less 836%) more effective at anti-aliasing than the Radeon RX 460 2GB, and able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 145760 (836%)

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 (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video 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 video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs 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 rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
