Radeon RX 5700 vs Radeon RX Vega 56

Intro

Compare those specifications 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 makes use of a 2048-bit bus, and makes use of a 14 nm design. It features 3584 SPUs, 224 Texture Address Units, and 64 Raster Operation Units.

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 little bit superior to the Radeon RX Vega 56 in general. (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 much (about 23%) more effective at AF than the Radeon RX 5700. (explain)

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

Pixel Rate

The Radeon RX 5700 is a lot (more or less 27%) better at AA than the Radeon RX Vega 56, and also will be capable of handling higher screen resolutions without slowing down too much. (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 largest amount of data (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
