GeForce RTX 3080 12 GB vs Radeon RX 460 2GB

Intro

Compare those specifications to the Radeon RX 460 2GB, which comes with a GPU core clock speed of 1090 MHz, and 2048 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 Texture Address Units, and 16 Raster Operation Units.

	Difference: 291760 (478%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 3080 12 GB is superior to the Radeon RX 460 2GB, and very much so. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 123680 (709%)

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 max amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. 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 bandwidth is, the lower the ability to get to the max fill rate.
