Radeon RX 6750 XT vs Radeon RX Vega 56

Intro

Compare all of that to the Radeon RX Vega 56, which comes with GPU core speed of 1156 MHz, and 8192 MB of HBM2 memory set to run at 1600 MHz through a 2048-bit bus. It also features 3584 SPUs, 224 Texture Address Units, and 64 ROPs.

Radeon RX Vega 56		419430 MB/sec
	Difference: 22938 (5%)

Texel Rate

The Radeon RX 6750 XT will be a lot (about 33%) more effective at texture filtering than the Radeon RX Vega 56. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon RX Vega 56		258944 Mtexels/sec
	Difference: 85056 (33%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6750 XT is a better choice, by a large margin. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 63616 (86%)

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 (in units of MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
