InterconnectEight Gaudi 3 accelerators on a universal baseboard, with twenty PCIe 5.0 x16 slots available for scale-out networkingDirect all-to-all between the eight accelerators at 4.2 TB/s bidirectional with no switching IC, plus 1.2 TB/s bidirectional scale-out over 6 OSFP connectors as 24x 200 Gbps RDMA (RoCE v2); host attach is 8x PCIe Gen 5.0 x16

Rows shown in grey are identical between the two.

Ingrasys GB6181I

Ingrasys' Gaudi node, and the second Intel accelerator system in this catalogue. Eight Gaudi 3 accelerators sit on a universal baseboard in a six OpenU liquid-cooled chassis, so like its AMD sibling this is an Open Compute part rather than a 19 inch one. What stands out against the rest of the field is the I/O: thirty-two NVMe drive bays and twenty PCIe 5.0 x16 slots, far more than the eight to twelve typical of an eight-accelerator machine, which suits Gaudi's design of scaling out over ordinary Ethernet rather than a proprietary fabric. Power is ten 3,000 W Platinum supplies in 5+5 redundancy, which is capacity rather than draw, so no system power is shown. Ingrasys publishes no throughput figure; per-accelerator compute is on the Gaudi 3 chip entry and the baseboard's figures on the linked Intel HLB-325 entry.

Intel Gaudi 3 HLB-325 Baseboard

Intel's eight-accelerator universal baseboard for Gaudi 3, and the unit Intel offers OEMs to build servers around. It carries eight HL-325L OAM mezzanine cards and connects them all-to-all at 4.2 TB/s bidirectional without a switching chip, which is the design's distinguishing choice: scale-up needs no switch silicon, and scale-out runs over standard Ethernet at 1.2 TB/s through six OSFP connectors rather than a proprietary fabric. Intel rates the whole assembly at 7.6 kW including the eight OAMs, draws it from a 54 V main input with 12 V standby, and sizes the board at 417 by 585 mm to drop into 19-inch server designs. Sold either as the bare HLB-325 or, as the HLFB-325L, pre-populated with eight cards and tested as one subsystem. Intel publishes no aggregate throughput figure for the baseboard, so none is shown: per-accelerator compute is on the Gaudi 3 chip entry, sourced to Table 5 of Intel's technical paper. Total memory of 1.024 TB is the eight cards' published 128 GB apiece.
