The AMD Radeon Pro Vega 16 and Vega 20, two new graphics configurations the 15 -inch MacBook Pro will have started from November, offering significant performance upgrades on the previous generation, including the use of compact HBM2 memory.

Produced on a 14-nanometer FinFET process, the Vega 16 and Vega 20 are claimed by Apple to be 60 percent faster than the Radeon Pro 560X GPUs currently provided to MacBook Pro customers as a high-end option. Just on this statistic alone, the upgrade will be very useful for mobile creative professionals.
The Vega 16 and Vega 20 have what AMD describes as "Vega next-generation computing units," with each having 16 and 20 computing units respectively. A feature called Rapid Packed Math will help make processing faster, accelerating workloads in real time and cutting down the required resources to complete repetitive tasks.
The included support for second-generation high bandwidth memory (HBM2) also provides a few additional bonuses compared to the more conventional GDDR5 memory used in other graphics cards. As the name suggests, it offers significantly more memory bandwidth per chip compared to GDDR5, while at the same time consuming less power.
HBM2 also offers physical space savings by being located on the GPU package, which can make for a smaller overall footprint for a GPU, and in turn offering notebook vendors like Apple more space for other components.
Mens de nye mulighederne vil give et betydeligt løft for grafisk ydeevne, vil de ikke være den eneste måten MacBook Pro-eiere kan få en forbedringsfordel. Under the event, Apple announced the Blackmagic eGPU Pro which will use Radeon RX Pro Vega 64 graphics, a significantly more powerful GPU than the discrete graphics options.
The choice to use the Vega 20 name for one of the two options is unusual, as it is believed by enthusiast PC users that the Vega 20 will be the first GPU from the company using a 7-nanometer process, a GPU that is expected to be released later this year. The desktop-class GPU is gezegd te bevatten tussen 16GB en 32GB of HBM2 en vereist tussen 150 watt en 300 watt om te rennen, die kan worden genuanceerd beschreven als niet-wenselijk voor notebookgebruik.
It is possible that AMD could rebadge the supposed card ahead of its formal launch, so to avoid confusion with the already publicly named Vega 20 for the MacBook Pro.
Apple will start selling new MacBook Pro models with Vega 16 and Vega 20 configurations from November 14, as custom orders from Apple directly and Apple Authorized Resellers. Pricing for the options has yet to be announced.
