GeForce RTX 2080 Ti vs Radeon RX 460 2GB

Intro

Compare all that to the Radeon RX 460 2GB, which features a clock speed of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit memory bus, and uses a 14 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
GeForce RTX 2080 Ti		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 Ti should be 463% quicker than the Radeon RX 460 2GB in general, because of its greater bandwidth. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 518784 (463%)

Texel Rate

The GeForce RTX 2080 Ti is much (more or less 502%) better at anisotropic filtering than the Radeon RX 460 2GB. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 306160 (502%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 2080 Ti is superior to the Radeon RX 460 2GB, and very much so. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 101360 (581%)

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 transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card 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 that the graphics card can possibly write 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 sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
