Radeon R7 250 vs Radeon RX 6750 XT

Intro

Compare all of that to the Radeon RX 6750 XT, which features core clock speeds of 2150 MHz on the GPU, and 2250 MHz on the 12288 MB of GDDR6 memory. It features 2560 SPUs as well as 160 Texture Address Units and 64 ROPs.

Radeon R7 250		24000 Mtexels/sec
	Difference: 320000 (1333%)

Pixel Rate

The Radeon RX 6750 XT will be quite a bit (approximately 1620%) more effective at full screen anti-aliasing than the Radeon R7 250, and also should be capable of handling higher resolutions while still performing well. (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 (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
