Radeon R7 250 vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which comes with GPU clock speed of 1700 MHz, and 16384 MB of GDDR6 memory running at 2000 MHz through a 256-bit bus. It also is made up of 3840 Stream Processors, 240 TAUs, and 96 Raster Operation Units.

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

Texel Rate

The Radeon RX 6800 will be quite a bit (more or less 1600%) better at anisotropic filtering than the Radeon R7 250. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 384000 (1600%)

Pixel Rate

The Radeon RX 6800 is quite a bit (about 1940%) better at FSAA than the Radeon R7 250, and also should be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 155200 (1940%)

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 transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
