Radeon RX 6750 XT vs Radeon RX Vega 56

Intro

The Radeon RX 6750 XT features core clock speeds of 2150 MHz on the GPU, and 2250 MHz on the 12288 MB of GDDR6 memory. It features 2560 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.

Compare all of that to the Radeon RX Vega 56, which features a core clock speed of 1156 MHz and a HBM2 memory speed of 1600 MHz. It also uses a 2048-bit memory bus, and uses a 14 nm design. It features 3584 SPUs, 224 TAUs, and 64 ROPs.

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

Texel Rate

The Radeon RX 6750 XT should be a lot (approximately 33%) better 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

The Radeon RX 6750 XT should be quite a bit (about 86%) more effective at full screen anti-aliasing than the Radeon RX Vega 56, and will be able to handle higher screen 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.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
