Radeon RX 560 vs Radeon RX Vega 56

Intro

Compare that to the Radeon RX Vega 56, which features a core clock frequency of 1156 MHz and a HBM2 memory frequency of 1600 MHz. It also features a 2048-bit bus, and makes use of a 14 nm design. It is made up of 3584 SPUs, 224 TAUs, and 64 Raster Operation Units.

Radeon RX 560		80 Watts
Radeon RX Vega 56		210 Watts
	Difference: 130 Watts (163%)

Memory Bandwidth

Performance-wise, the Radeon RX Vega 56 should in theory be a lot better than the Radeon RX 560 overall. (explain)

Radeon RX Vega 56		419430 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 304742 (266%)

Texel Rate

The Radeon RX Vega 56 should be much (approximately 244%) more effective at anisotropic filtering than the Radeon RX 560. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 183744 (244%)

Pixel Rate

The Radeon RX Vega 56 will be quite a bit (about 294%) better at AA than the Radeon RX 560, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX Vega 56		73984 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 55184 (294%)

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 data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant 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 max fill rate.
