These independently selected results can use different models, workloads and settings. They do not establish a hardware or model winner.
The memory shown in a source configuration belongs to that submission. For M3 Ultra purchases, Apple’s UK specification checked September 6, 2026 lists 96 GB configurable to 256 GB. Its 2025 launch announcement described up to 512 GB. Confirm the exact configuration; a family maximum is not the machine measured here.
