Radeon RX 5700 vs Radeon RX Vega 56

Intro

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

Radeon RX 5700		180 Watts
Radeon RX Vega 56		210 Watts
	Difference: 30 Watts (17%)

Memory Bandwidth

As far as performance goes, the Radeon RX 5700 should in theory be a small bit superior to the Radeon RX Vega 56 overall. (explain)

Radeon RX 5700		458752 MB/sec
Radeon RX Vega 56		419430 MB/sec
	Difference: 39322 (9%)

Texel Rate

The Radeon RX Vega 56 will be quite a bit (about 23%) better at texture filtering than the Radeon RX 5700. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 47984 (23%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 5700 is a better choice, by a large margin. (explain)

Radeon RX 5700		93760 Mpixels/sec
Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 19776 (27%)

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 data (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
