Apple was working on a next-generation graphics process unit (GPU) for the iPhone 14 Pro series.
The early prototypes required more power than expected based on software simulations run by Apple.
Prototype version of the chip drew too much power from the batteries found inside the iPhone 14 Pro and iPhone 14 Pro Max.
Additionally, these prototype GPUs also made the handsets run too hot.
But four sources familiar with the situation said that the issues were discovered too late in the GPU's development process.
Apple to base the new GPU integrated with the A16 Bionic SoC on the design of last year's
The next-gen GPU would have included advanced capabilities such as hardware-accelerated ray tracing.
This extra bit of realism can help take mobile games to another level.
The GPU used on the iPhone 14 Pro models doesn't take the huge step forward that Apple originally intended it to.
Apple's chip designing unit hasn't faced too many bumps in the road, so when they occur it is big news.
