Radeon RX 6750 XT vs Radeon RX Vega 56

Intro

Compare that to the Radeon RX Vega 56, which has GPU clock speed of 1156 MHz, and 8192 MB of HBM2 memory running at 1600 MHz through a 2048-bit bus. It also is made up of 3584 Stream Processors, 224 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX Vega 56		210 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 40 Watts (19%)

Memory Bandwidth

In theory, the Radeon RX 6750 XT should be 5% quicker than the Radeon RX Vega 56 overall, due to its greater bandwidth. (explain)

Radeon RX 6750 XT		442368 MB/sec
Radeon RX Vega 56		419430 MB/sec
	Difference: 22938 (5%)

Texel Rate

The Radeon RX 6750 XT will be a lot (more or less 33%) faster with regards to anisotropic 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 a high resolution is important to you, then the Radeon RX 6750 XT is superior to the Radeon RX Vega 56, and very much so. (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 (counted in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out 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 filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
