According to Mark Gurman's Power On newsletter, Apple is preparing to include up to 1.5TB of RAM in its upcoming M7 Ultra chip. This significant increase in RAM capacity is expected to match the highest RAM configuration available on the 2019 Intel Mac Pro.

The M7 Ultra chip is designed to support unified memory, allowing for high transfer speeds. However, widespread memory-chip shortages may impact the final RAM configuration of the chip. Apple is engineering the M7 Ultra to support up to 1.5TB of RAM, but it's unclear if the company will ultimately offer that configuration.

The discontinuation of the 512GB and 256GB configurations of the M3 Ultra Mac Studio suggests that Apple is moving towards a more limited RAM offering. The M7 Ultra chip is expected to support a wider range of RAM configurations, but the exact details are still unclear.
