GeForce RTX 3080 12 GB vs Radeon R7 250X 2GB

Intro

Compare all of that to the Radeon R7 250X 2GB, which features GPU core speed of 1000 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

	Difference: 862298 (1198%)

Texel Rate

The GeForce RTX 3080 12 GB is a lot (more or less 782%) more effective at texture filtering than the Radeon R7 250X 2GB. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 312800 (782%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 3080 12 GB is a better choice, and very much so. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 125120 (782%)

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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
