Radeon R7 240 vs Radeon RX 6900 XT

Intro

Compare that to the Radeon RX 6900 XT, which has a GPU core clock speed of 1825 MHz, and 16384 MB of GDDR6 memory running at 2000 MHz through a 256-bit bus. It also is comprised of 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240		30 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 270 Watts (900%)

Memory Bandwidth

In theory, the Radeon RX 6900 XT should be 1720% faster than the Radeon R7 240 overall, because of its higher bandwidth. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 495488 (1720%)

Texel Rate

The Radeon RX 6900 XT will be quite a bit (more or less 3900%) faster with regards to anisotropic filtering than the Radeon R7 240. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 569400 (3900%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6900 XT is the winner, by a large margin. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 227760 (3900%)

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 information (in units of megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
