A Chinese leaker known as Fried White Rice on Weibo has posted images of claimed circuit diagrams for the upcoming iPhone 18 Pro models. The images suggest the new A20 Pro chip may feature seven GPU cores—one more than its predecessor—and a faster memory interface. The diagrams, which show the chip's attachment to the circuit board, also indicate six CPU cores in the same configuration as last year's model: two high-performance cores and four efficiency cores.

The L2 cache for efficiency cores has been increased from 6 MB in the A19 Pro to 8 MB, while the big CPU cores remain at 16 MB. Determining GPU core count from solder diagrams is challenging, but the 7-core configuration is considered most plausible. Fixed Focus Digital recently suggested the A20 Pro will be 18% faster with 30% better power efficiency.

While the leaker has some credibility, these remain informed guesses rather than confirmed details.
