Radeon R7 240 vs Radeon RX 6800

Intro

Compare those specs to the Radeon RX 6800, which comes with GPU clock speed of 1700 MHz, and 16384 MB of GDDR6 RAM set to run at 2000 MHz through a 256-bit bus. It also is comprised of 3840 Stream Processors, 240 Texture Address Units, and 96 ROPs.

Radeon R7 240		28800 MB/sec
	Difference: 495488 (1720%)

Texel Rate

The Radeon RX 6800 will be quite a bit (more or less 2695%) more effective at AF than the Radeon R7 240. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 393400 (2695%)

Pixel Rate

The Radeon RX 6800 is much (more or less 2695%) faster with regards to full screen anti-aliasing than the Radeon R7 240, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 157360 (2695%)

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 maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
