Radeon RX 6750 XT vs Radeon RX Vega 56

Intro

Compare all of that to the Radeon RX Vega 56, which uses a 14 nm design. AMD has clocked the core speed at 1156 MHz. The HBM2 memory runs at a speed of 1600 MHz on this model. It features 3584 SPUs as well as 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

Theoretically speaking, the Radeon RX 6750 XT should be 5% quicker than the Radeon RX Vega 56 in general, due to its higher 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 quite a bit (approximately 33%) faster with regards to AF 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

The Radeon RX 6750 XT will be much (approximately 86%) better at full screen anti-aliasing than the Radeon RX Vega 56, and will be able to handle higher resolutions while still performing well. (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 max amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
