Open the recordWhat actually differs
- Different software stacks: the Framework Desktop · Ryzen AI Max+ runs ROCm and Vulkan, the Apple Mac Studio · M3 Ultra runs MLX and Metal. Check that your runtime and model format are supported before comparing numbers.
- The Framework Desktop · Ryzen AI Max+ has 32 GB more model memory (128 GB vs 96 GB). That decides which models fit at all.
- Memory bandwidth is not in the record for the Framework Desktop · Ryzen AI Max+, so the Lab cannot compare generation speed ceilings.
- No public list price in the record for the Apple Mac Studio · M3 Ultra. Ask the supplier for a configured quote.

Before you choose
Framework Desktop · Ryzen AI Max+
- The 128 GB memory is soldered. GPU-available memory depends on OS and configuration.
- The listed $3,449 is the 128 GB system kit selection, not a ready-to-run total. SSD, OS, fan, cable and tiles are additional selections.
Apple Mac Studio · M3 Ultra
- This is a specific M3 Ultra configuration, not a claim that it is the latest Mac Studio.
- CUDA workloads need a different platform. UT’s complete managed stack is not validated here.
