Radeon HD 7750 vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which makes use of a 7 nm design. AMD has set the core frequency at 1626 MHz. The GDDR6 RAM works at a speed of 1750 MHz on this specific model. It features 1792 SPUs as well as 112 Texture Address Units and 64 Rasterization Operator Units.

Radeon HD 7750		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The Radeon RX 6600 should be quite a bit (about 611%) better at AF than the Radeon HD 7750. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 156512 (611%)

Pixel Rate

The Radeon RX 6600 should be quite a bit (more or less 713%) better at anti-aliasing than the Radeon HD 7750, and also able to handle higher resolutions while still performing well. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 91264 (713%)

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 (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, 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 most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
