Radeon HD 6750 vs Radeon RX 6500 XT

Intro

Compare that to the Radeon RX 6500 XT, which comes with GPU core speed of 2200 MHz, and 4096 MB of GDDR6 RAM set to run at 2250 MHz through a 64-bit bus. It also is made up of 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750		86 Watts
Radeon RX 6500 XT		107 Watts
	Difference: 21 Watts (24%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6500 XT should perform much faster than the Radeon HD 6750 in general. (explain)

Radeon RX 6500 XT		147456 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 83456 (130%)

Texel Rate

The Radeon RX 6500 XT is a lot (approximately 439%) more effective at anisotropic filtering than the Radeon HD 6750. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 114700 (439%)

Pixel Rate

The Radeon RX 6500 XT should be quite a bit (more or less 507%) better at AA than the Radeon HD 6750, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 58800 (507%)

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 maximum amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
