Radeon RX 6750 XT vs Radeon RX Vega 64

Intro

Compare those specs to the Radeon RX Vega 64, which comes with core speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 RAM. It features 4096 SPUs along with 256 Texture Address Units and 64 Rasterization Operator Units.

Radeon RX 6750 XT		250 Watts
Radeon RX Vega 64		295 Watts
	Difference: 45 Watts (18%)

Memory Bandwidth

Theoretically, the Radeon RX Vega 64 should perform a little bit faster than the Radeon RX 6750 XT overall. (explain)

Radeon RX Vega 64		495411 MB/sec
Radeon RX 6750 XT		442368 MB/sec
	Difference: 53043 (12%)

Texel Rate

The Radeon RX 6750 XT will be just a bit (more or less 8%) more effective at AF than the Radeon RX Vega 64. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon RX Vega 64		319232 Mtexels/sec
	Difference: 24768 (8%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6750 XT is a better choice, by far. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon RX Vega 64		79808 Mpixels/sec
	Difference: 57792 (72%)

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 transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
