Apple A16 could have a 15% faster CPU and up to a 30% faster GPU


In a nutshell: Apple is anticipated to additional outline the road between its mainstream and flagship iPhones come September when the subsequent technology of units are launched. Most consider Apple will do that by reserving its A16 SoC for Professional-tier iPhones and delivery its different new iPhones with the A15 from the iPhone 13 household.

Jason Cross from Macworld just lately regarded on the broad image together with previous enhancements to attempt to predict what kind of efficiency we are able to count on from the A16. The final consensus from the rumor mill is that Apple will manufacture the A16 on a 5nm course of, identical to it did with the A15 and A14 earlier than it.

The A16 will probably use TSMC’s third-gen 5nm course of, which can solely supply a slight efficiency and effectivity enhance. A way more important soar in efficiency and effectivity will come when Apple adopts a chip constructed on a 3nm course of, however that is not anticipated to be prepared for the pending iPhone 14 launch.

Cross believes the A16 might pack as much as 20 billion transistors, a lot of which will likely be used to energy the Neural Engine for machine studying in addition to the picture sign processor (ISP) and video encoders / decoders.

The iPhone 14 Professional is rumored to characteristic a brand new 48MP digital camera which would require wider and quicker knowledge paths to the ISP. With out enough infrastructure, picture processing occasions would undergo and that is not congruent with Apple’s technique.

The A16 will probably persist with the identical core configuration of two efficiency cores alongside 4 high-efficiency cores.

Cross additional expects Apple to implement LPDDR5 reminiscence this yr, a transfer that will little question enhance reminiscence bandwidth. Going from LPDDR4x to LPDDR5 might enhance reminiscence bandwidth by as a lot as 50 p.c. Cross by means of Apple would make the soar final yr however in fact, it did not occur.

Together with a number of different tweaks, we might see the A16 ship as much as a 15 p.c efficiency enchancment over its predecessor.

On the GPU aspect, it’s believed that Apple will go together with 5 GPU cores on the A16 or perhaps six, however no more than that. Once more, different architectural enhancements and the transfer to LPDDR5 reminiscence will solely enhance graphics efficiency much more.

All issues thought of, we might see a efficiency enhance of as much as 30 p.c in comparison with final yr’s A15 on the GPU aspect.

Lastly, Cross believes the iPhone 14 Professional will use Qualcomm’s Snapdragon X65 modem as an alternative of its long-rumored homegrown 5G modem. Final yr’s iPhone 13 Professional was geared up with a Snapdragon X60 5G chip; the X65 gives as much as 10Gbit/s of peak obtain pace in comparison with 7.5Gbit/s on the X60.

Some consider Apple’s personal 5G chip might be able to debut in 2023 whereas others really feel main setbacks will push it a number of years out.
