GeForce RTX 2080 SUPER vs Radeon R7 240

Intro

Compare those specifications to the Radeon R7 240, which has a core clock speed of 730 MHz and a DDR3 memory speed of 900 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is made up of 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

Radeon R7 240		14600 Mtexels/sec
	Difference: 302200 (2070%)

Pixel Rate

The GeForce RTX 2080 SUPER should be much (more or less 1708%) better at AA than the Radeon R7 240, and also should be able to handle higher resolutions more effectively. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 99760 (1708%)

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 maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
