Framework Desktop (Ryzen AI Max+ 395, 64 GB)
An APU with a 256-bit LPDDR5X bus and 40 RDNA 3.5 compute units, sold in mini-PCs with up to 128 GB of shared memory. The cheapest way to put a 100B-class MoE model entirely in memory, at roughly a third of the bandwidth of a Mac Studio Ultra.

Calculated
The $100 comparison uses the Codex Pro 5x / Claude Max 5x plans. A fixed planning conversion is used for USD. This compares monthly spend only: subscriptions have usage limits, local hardware has different capabilities and constraints, and taxes or regional pricing may change the charged amount. Prices checked 7 September 2026.

Three different numbers, deliberately
Cash cost
$0
Money that leaves the bank account on day one, net of reclaimable VAT.
Accounting depreciation
$0.00/month
$0 written down over 5 years to a $0 residual.
After-tax economic cost
$0.69/month
Depreciation plus running costs plus cost of capital, less the tax those deductions save. This is the figure to compare between machines.
