Radeon HD 6750 vs Radeon RX 6600

Intro

Compare all that to the Radeon RX 6600, which makes use of a 7 nm design. AMD has set the core speed at 1626 MHz. The GDDR6 RAM runs at a speed of 1750 MHz on this particular card. It features 1792 SPUs along with 112 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750		86 Watts
Radeon RX 6600		132 Watts
	Difference: 46 Watts (53%)

Memory Bandwidth

In theory, the Radeon RX 6600 will be 258% quicker than the Radeon HD 6750 in general, due to its greater data rate. (explain)

Radeon RX 6600		229376 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 165376 (258%)

Texel Rate

The Radeon RX 6600 will be quite a bit (about 598%) better at anisotropic filtering than the Radeon HD 6750. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 156012 (598%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6600 is a better choice, and very much so. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 92464 (797%)

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 max amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better 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 a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
