Macrostack — AI Accelerators
24 accelerators from 13 vendors, with the field every other comparison leaves out: whether you can actually get one.
Maintained at macrostack.net/silicon.
Verified 2026-09-06.
Why this exists
Every published accelerator comparison ranks on FLOPS and memory. Almost none of them tell you that 7 of these cannot be bought at any price — they exist only inside a single cloud, so choosing one is choosing a vendor permanently. Only 5 can be purchased outright.
That is the column that decides real procurement, and it is the reason this table is not a rewrite of a spec sheet.
Honesty rules this data follows
- Every numeric field is a string, and "not published" is a permitted value. Microsoft publishes almost nothing about Maia 200. This says so rather than estimating, because an invented TDP is worse than an absent one — it gets quoted.
the_catchis mandatory on every row. The limitation a vendor will not lead with is the most useful sentence about any of these parts.- No commission exists at this layer and we take none. There is no affiliate programme for compute, which is precisely why a neutral version of this table did not previously exist.
