Radeon RX 6700 XT vs Radeon RX Vega 56

Intro

Compare that to the Radeon RX Vega 56, which has GPU core speed of 1156 MHz, and 8192 MB of HBM2 RAM set to run at 1600 MHz through a 2048-bit bus. It also is comprised of 3584 SPUs, 224 TAUs, and 64 ROPs.

	Difference: 20 Watts (10%)

Memory Bandwidth

Theoretically speaking, the Radeon RX Vega 56 should be a small bit faster than the Radeon RX 6700 XT in general. (explain)

Radeon RX Vega 56		419430 MB/sec
Radeon RX 6700 XT		393216 MB/sec
	Difference: 26214 (7%)

Texel Rate

The Radeon RX 6700 XT should be much (about 43%) faster with regards to texture filtering than the Radeon RX Vega 56. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon RX Vega 56		258944 Mtexels/sec
	Difference: 112416 (43%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6700 XT is a better choice, by a large margin. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 74560 (101%)

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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video 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 ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
