That image processor has to be able to handle four times the pixels (or else take four times as long to process the image, unlikely given Apple’s priority on camera responsiveness) You have to have wider and faster data paths to the image signal processor. You can’t just slap in a 48MP sensor and call it a day. Cross therefore expects most of the extra performance to focus on image-processing and AI. Both Kuo and fellow analyst Jeff Pu expect this to come to the main camera. There’s one expected iPhone 14 Pro feature that will need all the processing power it can get: a 48MP camera sensor, supporting 8K video. You’ll especially see this in benchmarks and tests that are currently limited by memory bandwidth. We think it’s reasonable to expect a 25 percent to 30 percent improvement in GPU performance, roughly in line with the last several A-series processors. He thinks a potential extra core, architectural improvements, and access to faster memory will see the usual improvement here. should improve memory bandwidth, and some other improvements, combined with higher peak clock speeds, might get Apple up to a 15 percent performance improvement.Ĭross discusses possible ARMv9 support, but thinks that unlikely to make much difference, before moving on to GPU performance. This is the faster memory Apple uses in the M1 Pro and Max chips. Back in March, Apple analyst said that the iPhone 14 Pro models would get an upgrade from LPDDR4 to LPDDR5, a report today echoed by Digitimes. It is, however, expected to get faster memory. N4P offers and 11 percent performance boost, 22 percent power efficiency improvement, and 6 percent improvement in density over the original 5nm “N5” manufacturing process. This offers some performance boost, but a relatively modest one. All comparisons are to the iPhone 13 Pro.įirst, there’s no guesswork involved when it comes to the chip fabrication process: TSMC’s most advanced process is a third-gen 5nm process known as N4P. Macworld’s Jason Cross gave it his best shot. There’s a lot of guesswork involved in what that might mean in terms of iPhone 14 Pro performance, but it is possible to at least get a rough steer … That suggests that iPhone 14 Pro performance could be considerably better than the base models. The base model iPhone 14 (and its larger counterpart) is expected to stick to an A15 chip this year, while the Pro models get an A16.
