Radeon RX 5700 vs Radeon RX Vega 56

Intro

Compare those specifications to the Radeon RX Vega 56, which comes with GPU core speed of 1156 MHz, and 8192 MB of HBM2 memory running at 1600 MHz through a 2048-bit bus. It also is comprised of 3584 Stream Processors, 224 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The Radeon RX 5700, in theory, should be a small bit faster than 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 is a lot (about 23%) better at anisotropic 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 running with high levels of AA is important to you, then the Radeon RX 5700 is superior to the Radeon RX Vega 56, and very much so. (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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, 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 most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs 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 quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
