Radeon RX 6750 XT vs Radeon RX Vega 56

Intro

The Radeon RX 6750 XT features a GPU core speed of 2150 MHz, and the 12288 MB of GDDR6 memory runs at 2250 MHz through a 192-bit bus. It also is comprised of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Compare all that to the Radeon RX Vega 56, which makes use of a 14 nm design. AMD has set the core speed at 1156 MHz. The HBM2 memory is set to run at a speed of 1600 MHz on this card. It features 3584 SPUs along with 224 Texture Address Units 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 will be 5% quicker than the Radeon RX Vega 56 overall, 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 a lot (about 33%) better at 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

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
