Radeon R7 250 vs Radeon RX 6750 XT

Intro

Compare all of that to the Radeon RX 6750 XT, which features a core clock speed of 2150 MHz and a GDDR6 memory frequency of 2250 MHz. It also makes use of a 192-bit bus, and makes use of a 7 nm design. It features 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Radeon R7 250		65 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 185 Watts (285%)

Memory Bandwidth

Theoretically, the Radeon RX 6750 XT should perform quite a bit faster than the Radeon R7 250 overall. (explain)

Radeon RX 6750 XT		442368 MB/sec
Radeon R7 250		73600 MB/sec
	Difference: 368768 (501%)

Texel Rate

The Radeon RX 6750 XT should be much (about 1333%) faster with regards to texture filtering than the Radeon R7 250. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 320000 (1333%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6750 XT is a better choice, by far. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 129600 (1620%)

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 maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 are applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines 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 fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
