AMD Polaris and Vega GPUs only to receive critical updates AMD is sunsetting its Polaris and Vega support on Windows. The company will only provide critical security patches. It has been long speculated that AMD has already abandoned the Vega and Polaris architectures, but the company has now confirmed that this is indeed the case. […]
They will still make regular updates for bugs/security. There are millions of these units in production and AMD is not dropping support for them.
These older architectures are just not a focus for new features and the drivers are being split out into a sperate package.
They said :
If a laptop with a 7730u meets your needs today it likely will continue doing so for some time. That said, obviously older architectures are closer to EOL than newer ones so that comes with pros and cons. Cheaper but official support will drop off sooner.
Not sure how an APU with a 680M or 780M stacks up in price.
