GeForce RTX 2080 SUPER vs Radeon RX 460

Intro

Compare all that to the Radeon RX 460, which comes with GPU clock speed of 1090 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER will be 353% quicker than the Radeon RX 460 in general, due to its greater data rate. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon RX 460		112000 MB/sec
	Difference: 395904 (353%)

Texel Rate

The GeForce RTX 2080 SUPER will be much (more or less 419%) faster with regards to anisotropic filtering than the Radeon RX 460. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon RX 460		61040 Mtexels/sec
	Difference: 255760 (419%)

Pixel Rate

The GeForce RTX 2080 SUPER will be quite a bit (more or less 506%) better at anti-aliasing than the Radeon RX 460, and also should be able to handle higher resolutions more effectively. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 88160 (506%)

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 maximum amount of information (counted in MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 potential to get to the maximum fill rate.
