Radeon R7 260X vs Radeon RX 6800 XT

Intro

Compare that to the Radeon RX 6800 XT, which comes with a clock frequency of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It is made up of 4608 SPUs, 288 TAUs, and 128 ROPs.

Radeon R7 260X		104000 MB/sec
	Difference: 420288 (404%)

Texel Rate

The Radeon RX 6800 XT should be quite a bit (approximately 753%) more effective at texture filtering than the Radeon R7 260X. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Radeon R7 260X		61600 Mtexels/sec
	Difference: 464000 (753%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6800 XT is superior to the Radeon R7 260X, by far. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon R7 260X		17600 Mpixels/sec
	Difference: 216000 (1227%)

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 data (in units of MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher 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 one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 bandwidth is, the lower the potential to reach the maximum fill rate.
