A Chinese leaker with some track record has posted images of claimed circuit diagrams of the upcoming iPhone 18 Pro models.
These suggest that the new A20 Pro chip may have seven GPU cores – one more than its predecessor – and a faster memory interface …
The images posted by Weibo user Fried White Rice are not of the A20 Pro chip itself, but rather diagrams of where the chip will be attached to the underlying circuit board. From this, they’re making inferences about the power and architecture of the new chip, drawing two main conclusions about likely improvements.
First, the diagrams point to six CPU cores in the same configuration as last year’s model: two high-performance ones and four efficiency cores. However, it appears that the cache memory for the efficiency cores has been increased.
We can see that the L2 cache for the small CPU cores has been increased—likely from 6 MB in the A19 Pro to 8 MB—while the L2 cache for the big CPU cores remains unchanged at 16 MB.
