Radeon HD 6750 1GB vs Radeon RX 6600 XT

Intro

Compare that to the Radeon RX 6600 XT, which uses a 7 nm design. AMD has clocked the core speed at 1968 MHz. The GDDR6 memory works at a speed of 2000 MHz on this particular card. It features 2048 SPUs along with 128 Texture Address Units and 64 ROPs.

Radeon HD 6750 1GB		64000 MB/sec
	Difference: 198144 (310%)

Texel Rate

The Radeon RX 6600 XT will be a lot (more or less 865%) better at AF than the Radeon HD 6750 1GB. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 225804 (865%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6600 XT is superior to the Radeon HD 6750 1GB, by far. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 114352 (986%)

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 max amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 can be applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to 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 bandwidth is, the lower the ability to reach the max fill rate.
