Radeon HD 6750 vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 1968 MHz. The GDDR6 memory is set to run at a frequency of 2000 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

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

Pixel Rate

The Radeon RX 6600 XT will be quite a bit (approximately 986%) faster with regards to AA than the Radeon HD 6750, and able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon HD 6750		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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 applied in one 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
