| Summary | Has a DRAM cache and is sold only with a fan-cooled heatsink, as it can run hot under sustained load. | Draws less power than the NM1090 but ships without a heatsink, so it may need one under sustained load. | DRAM-less, unlike the NM1090 and NM1090 PRO; it borrows a little system memory (HMB) instead. |
