GeForce RTX 3080 12 GB vs Radeon HD 6750

Intro

Compare all of that to the Radeon HD 6750, which features GPU core speed of 725 MHz, and 512 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 720 Stream Processors, 36 Texture Address Units, and 16 Raster Operation Units.

	Difference: 264 Watts (307%)

Memory Bandwidth

In theory, the GeForce RTX 3080 12 GB will be 1360% faster than the Radeon HD 6750 in general, due to its higher data rate. (explain)

GeForce RTX 3080 12 GB		934298 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 870298 (1360%)

Texel Rate

The GeForce RTX 3080 12 GB is quite a bit (more or less 1252%) better at texture filtering than the Radeon HD 6750. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 326700 (1252%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 3080 12 GB is a better choice, and very much so. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 129520 (1117%)

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 (in units of MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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