Radeon RX 560 vs Radeon RX Vega 64

Intro

Compare those specifications to the Radeon RX Vega 64, which uses a 14 nm design. AMD has set the core frequency at 1247 MHz. The HBM2 RAM is set to run at a speed of 1890 MHz on this specific card. It features 4096 SPUs along with 256 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
Radeon RX Vega 64		295 Watts
	Difference: 215 Watts (269%)

Memory Bandwidth

In theory, the Radeon RX Vega 64 should be 332% faster than the Radeon RX 560 overall, because of its higher bandwidth. (explain)

Radeon RX Vega 64		495411 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 380723 (332%)

Texel Rate

The Radeon RX Vega 64 should be quite a bit (more or less 325%) faster with regards to AF than the Radeon RX 560. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 244032 (325%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX Vega 64 is a better choice, by far. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 61008 (325%)

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 largest amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
