What to compare closely
This table starts with model specifications. Choose a configuration to compare included memory, storage and captured prices. Adding a PC keeps your selection in a shareable comparison.
- K1 lists 16GB onboard LPDDR4X that cannot be upgraded or replaced. M5 Ultra lists two DDR4 SO-DIMM slots and support up to 64GB; decide your likely memory needs before choosing the fixed-memory model.
- K1 lists one Gigabit Ethernet port; M5 Ultra lists two 2.5GbE ports. Multiple wired connections or faster network equipment make this a practical distinction to inspect.
- K1 has a complete 16GB RAM and 512GB SSD offer. M5 Ultra includes a barebone and a matching-capacity 16GB/512GB package; compare the complete packages when you need equivalent included hardware.
