A PlayStation Handheld Capable of Running PS4 Games Natively Would Be Very Hard to Achieve
A PlayStation handheld console capable of running PS4 games natively would be very hard to achieve, mostly due to power draw and memory bandwidth, among other reasons.
Replying to a fan question regarding the rumored handheld, which is said to be in the works, the tech experts at Digital Foundry highlighted how a portable console capable of running PlayStation 4 games natively would be very hard to achieve due to power draw and the massive memory bandwidth of the system, 176 GB/s.

Powered by a custom AMD APU, this handheld is currently in the High Level Design Phase, meaning it is at least two years from release and has yet to be greenlit. Specs have yet to be finalized a swell, but it is said the system will use 18 CUs, and its GPU will likely run at 1.8 GHz or slower due to the PlayStation 5's variable clock speeds.
Following the PlayStation Vita, which could have been much more successful with better support thanks to its great hardware at the time, Sony left the handheld market, only to
