AMD Radeon Pro Vega 16 and Vega 20, two new graphics configurations that the 15-inch MacBook Pro will have as of November, will offer significant performance improvements over the previous generation, including through the use of 39, a compact memory HBM2.

Produced on a 14 nanometer FinFET process, the Vega 16 and Vega 20 would be, according to Apple, 60% faster than the Radeon Pro 560X GPUs currently offered to MacBook Pro customers as a premium option. Just on this statistic, the upgrade will be very useful for mobile creative professionals.
Vega 16 and Vega 20 have what AMD describes as "new generation Vega computing units", each with 16 and 20 calculation units respectively. A feature called Rapid Packed Math will speed up processing, speed up workloads in real time, and reduce the resources required to perform repetitive tasks.
The included support for second generation broadband memory (HBM2) also provides some additional bonuses over the more conventional GDDR5 memory used in other graphics cards. As the name suggests, it offers significantly more memory bandwidth per chip than GDDR5, while consuming less power.
HBM2 also saves physical space by lying on the GPU package, which can reduce the overall footprint of a GPU and by offering laptops to laptops. like Apple more space for other components.
While the new options will dramatically improve graphics performance, they will not be the only way for MacBook Pro users to gain a treatment advantage. During the event, Apple announced the Blackmagic eGPU Pro, which will use the Radeon RX Pro Vega 64 graphics, a significantly more powerful GPU than the discrete graphics options.
The choice of using the Vega 20 name for one of the two options is unusual, as passionate PC users believe that the Vega 20 will be the company's first GPU using a 7-nanometer process, a GPU who should be released later this year. The desktop class graphics processor has between 16 and 32 GB of HBM2 and requires between 150 and 300 watts to operate, which can be generously described as undesirable for use with a laptop.
It is possible that AMD will modify the supposed map again before its official launch, in order to avoid any confusion with the Vega 20 already publicly named for MacBook Pro.
Apple will begin selling new MacBook Pro models with Vega 16 and Vega 20 configurations starting Nov. 14, as custom orders from Apple directly and Apple Authorized Resellers. The price of the options has not been announced yet.
