Rebellions RebelRack
A 42U rack of four RebelServers holding 32 Rebel100 cards, rated by Rebellions at 65.5 PFLOPS FP8 and 32.7 PFLOPS FP16, with 4.61 TB of HBM3E at 153.6 TB/s and 6 TB of DDR5 across eight AMD EPYC 9355 processors totalling 256 cores and 512 threads. It draws up to 28 kW and rejects 105,094 BTU/hour at maximum, in a 600 by 1200 mm footprint weighing about 351 kg unpackaged. Figures here are the exact products of the per-card specification, which reconcile to Rebellions' printed 65.5 and 32.7. All figures are dense: Rebellions labels the Rebel100 compute "Compute (Dense)" and publishes no sparse rate.
