GeForce GTX 750 vs Radeon RX 6750 XT

Intro

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

GeForce GTX 750		80000 MB/sec
	Difference: 362368 (453%)

Texel Rate

The Radeon RX 6750 XT should be much (approximately 954%) more effective at anisotropic filtering than the GeForce GTX 750. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 311360 (954%)

Pixel Rate

The Radeon RX 6750 XT will be a lot (more or less 743%) more effective at AA than the GeForce GTX 750, and also will be capable of handling higher resolutions more effectively. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
GeForce GTX 750		16320 Mpixels/sec
	Difference: 121280 (743%)

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 largest amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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 reach the max fill rate.
