In layman's terms, these next-get Furian graphics cards are bringing big performance and power efficiency boosts to the table. Apple is a stakeholder and licencee in Imagination Technologies and has been using the PowerVR series in many of its devices, so we will almost certainly see Cupertino employ the new technology in the future. This in turn means that upcoming iPhones will be capable of supporting 4K graphics, higher-resolution gaming, demanding machine learning apps, and improved augmented/virtual reality capabilities, all without breaking the battery bank.
Sam Rosen, managing director and VP, video, OTT, and AR/VR at ABI Research has commented on the new Furian architecture:
Of course, Imagination Technologies also went to into detail about the improvements that the new Furian series have achieved. Compared to a similar sized and clocked 7XT Plus GPU on the Rogue architecture, the new 8XT GPUs boast between a 70-90% enhancement in gaming performance by density, including 35% improved GFLOPS performance and 80% fillrate density improvement for better UI and casual gaming.
The new technology has already been licensed to manufacturers and should be available in mobile devices by the end of 2018. This indicates that we won't see it on the iPhone 8, but a Furian GPU might be present in Apple's next year flagship.
