Rumors suggest Apple will soon update its MacBook Pro lineup with the higher-end M5 Pro and M5 Max processors, featuring a new architecture for better scalability. These chips are set to debut in the 14- and 16-inch models later this month or in March, alongside macOS 26.3. The changes aim to enhance GPU performance for AI and graphics while addressing efficiency issues.
Apple's forthcoming M5 Pro and M5 Max processors are rumored to introduce a significant architectural shift from the base M5 chip, moving away from the traditional system-on-chip (SoC) layout to a custom variation of TSMC's system-on-integrated-chip molding-horizontal (SoIC-MH) design. This change, as reported by CNET, would allow for separate chiplets, particularly isolating the GPU to enable independent scaling of its performance without relying on combining multiple dies—a method previously used for Pro, Max, and Ultra variants that has proven inefficient.
The SoIC-MH layout positions chiplets horizontally next to the main die rather than stacking them, potentially reducing heat generation, improving speed, and extending battery life. With growing demand for tensor processing in AI and graphics power, this setup is expected to let Apple pack more GPU cores, making devices like a 14-inch MacBook Pro more competitive for machine-learning workloads. CNET notes that the M5 already includes a neural accelerator per GPU core for AI tasks, but the chiplet approach could accelerate further enhancements.
These M5 Pro and Max chips are slated for both 14- and 16-inch MacBook Pro models, following the base M5's debut in the 14-inch version last October. The 16-inch model, still on older silicon, will receive the update simultaneously. Performance tests of the base M5 show substantial gains in on-GPU AI processing and ray-traced graphics over the M4, though it lags in AAA gaming.
Pricing is expected to hold steady amid a global RAM shortage, starting at $1,999 for the 14-inch with M5 Pro and $2,499 for the 16-inch. The update will be internal, with no design changes, and coincides with macOS 26.3 in February or March. Experts recommend waiting for these models if considering a purchase, as the decoupled CPU and GPU configurations could offer more flexible options for budget-conscious users focused on AI or gaming development.
