Radeon R7 250 vs Radeon RX 6900 XT

Intro

Compare that to the Radeon RX 6900 XT, which uses a 7 nm design. AMD has set the core speed at 1825 MHz. The GDDR6 memory runs at a frequency of 2000 MHz on this specific card. It features 5120 SPUs as well as 320 TAUs and 128 ROPs.

Radeon R7 250		73600 MB/sec
	Difference: 450688 (612%)

Texel Rate

The Radeon RX 6900 XT is quite a bit (approximately 2333%) more effective at texture filtering than the Radeon R7 250. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 560000 (2333%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6900 XT is the winner, and very much so. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 225600 (2820%)

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 max amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
