Different platforms, same budget

Framework Desktop · Ryzen AI Max+ vs Apple Mac Studio · M5 Ultra

Memory, bandwidth, software stack, price and the models each one can hold. Generated from the two sourced machine records; estimates are labelled.

Framework Desktop · Ryzen AI Max+

128 GB shared system memory

96 GB unified · selected model

What actually differs

Different software stacks: the Framework Desktop · Ryzen AI Max+ runs ROCm and Vulkan, the Apple Mac Studio · M5 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 either machine, so the Lab cannot compare generation speed ceilings.
No public list price in the record for the Apple Mac Studio · M5 Ultra. Ask the supplier for a configured quote.

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 store lists this configuration for pre-order, available from 22 September. No usable price was exposed in the reviewed store page.
This is a new configuration. Runtime compatibility, actual GPU memory allowance and performance have not been validated by this lab.
