Apple is expected to release the new iPhone 14 series this fall. The iPhone 14 standard version and iPhone 14 Max will use the A15 chip, while the iPhone 14 Pro and iPhone 14 Pro Max models will use the A16 chip. So the iPhone 14 Pro will perform much better than the iPhone 14 Standard.
Now Macworld has come up with performance predictions for the iPhone 14 Pro, all compared to the iPhone 13 Pro.
First of all, it is determined in terms of chip manufacturing process: the third-generation 5nm process of TSMC N4P is adopted. This brings some relatively modest performance gains.
Compared to the original 5nm “N5” manufacturing process, N4P offers 11% performance improvement, 22% energy efficiency improvement and 6% density improvement.
The iPhone 14 Pro is expected to get faster memory. Back in March, analysts said the iPhone 14 Pro models would be upgraded from LPDDR4 to LPDDR5 (6GB), and a report from Digitimes today agrees. This is the faster memory Apple uses in the M1 Pro and M1 Max chips.
“There should be increased memory bandwidth, along with several other improvements, which, combined with higher peak clock speeds, could give Apple chips up to 15 percent better performance.”
Macworld discussed the possibility of ARMv9 support, but didn’t think it would have much impact. In terms of GPU performance, there will be potential additional cores, architectural improvements and faster memory access.
“We think it’s reasonable to expect a 25% to 30% increase in GPU performance, which is roughly on par with recent A-series processors. You’ll see this in current benchmarks and tests that are limited by memory bandwidth. “
The iPhone 14 Pro is expected to require enhanced processor performance: an upgrade to a 48-megapixel camera sensor that supports 8K video capture. Earlier, Ming-Chi Kuo said that the main camera uses 48 million pixels. As such, Macworld expects that most of the extra performance will be focused on image processing and artificial intelligence.
“It’s not simply loading a 48MP sensor. There has to be a wider, faster data path to the image signal processor. The image processor has to be able to process four times as many pixels (or take four times as long to process the image – given that Apple Priority on camera responsiveness, which is unlikely) …
In other words, this new camera may require a more powerful image signal processor and neural engine (dedicated hardware for artificial intelligence and machine learning tasks). We’re sure Apple would love to improve the Cinema mode introduced with the iPhone 13 Pro. For example, it’s currently limited to 1080p shooting, but stepping up to 4K shooting requires more image processing power. The same goes for more natural AI bokeh or multi-object tracking. There’s a good reason why Apple is serious about beefing up its graphics processor and Neural Engine. “
Below is another area that will benefit from greater memory bandwidth.
“The transition from LPDDR4x to LPDDR5 will increase memory bandwidth by up to 50% and have a positive impact on energy efficiency. This by itself does not make any task faster, it just provides high bandwidth for things like 3D graphics and image/video processing Operations provide more breathing room.”
