MSI
ProcessorApple M4; 10-core CPU (4 performance, 6 efficiency); 16-core Neural Engine AppleIntel Core Ultra 9 275HX; 2.1–5.4 GHz

Arrow Lake-HX generation 24-core processor (8 performance, 16 efficiency) on the Intel HM870 chipset. There is no Hyper-Threading, so each core runs one thread.

MSI
Graphics8-core GPU; 10-core GPU option; hardware ray tracing

The 10-core GPU is a configure-to-order option; the base model has 8 cores.

Apple		NVIDIA GeForce RTX 5090 Laptop GPU, 24 GB GDDR7; 150 W maximum graphics power with Dynamic Boost; up to 1875 MHz boost

The laptop RTX 5090 is not the same card as the desktop RTX 5090. 150 W is the ceiling MSI sets for this thin chassis, so slightly lower GPU performance than thicker 175 W models is expected. MSI quotes 1824 AI TOPS.

MSI
Memory16 GB; 24 / 32 GB options

Unified memory; cannot be upgraded after purchase.

Apple		64 GB (2 × 32 GB) DDR5-5600; 2 SO-DIMM slots, up to 96 GB

Both slots come populated, so an upgrade means replacing the modules. MSI lists support up to DDR5-6400; the actual speed depends on the memory combination and the CPU.

MSI
Storage256 GB; 512 GB / 1 / 2 TB options Apple2 TB NVMe PCIe Gen4 x4 SSD; 1 M.2 slot

There is no second SSD slot; MSI advises consulting a service centre before upgrading the SSD.
