Radeon HD 7750 vs Radeon RX 6700 XT

Intro

Compare all that to the Radeon RX 6700 XT, which has a clock speed of 2321 MHz and a GDDR6 memory speed of 2000 MHz. It also features a 192-bit memory bus, and uses a 7 nm design. It is comprised of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Radeon HD 7750		72000 MB/sec
	Difference: 321216 (446%)

Texel Rate

The Radeon RX 6700 XT will be quite a bit (approximately 1351%) more effective at texture filtering than the Radeon HD 7750. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 345760 (1351%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6700 XT is the winner, and very much so. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 135744 (1061%)

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 information (counted in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
