Gaudi 2 vs RTX 3080

Memory bandwidth of 2450 GB/s on the Gaudi 2 supports larger batch sizes than the 760 GB/s on the RTX 3080 during data intensive operations. The RTX 3080 delivers FP16 dense performance at 59.5 TFLOPS and FP16 with sparsity at 119 TFLOPS along with FP32 at 29.8 TFLOPS which enables direct comparison of dense figures against other dense figures. Higher bandwidth on the Gaudi 2 permits increased data throughput per watt despite its 600W TDP compared to the 320W TDP of the RTX 3080. The absence of published tensor figures for the Gaudi 2 shifts emphasis to its 96 GB capacity for sustaining extended training sequences without the sparsity adjustments available on the RTX 3080 at 476 TOPS INT8 with sparsity.

The Gaudi 2 suits scenarios that require 96 GB HBM2e memory to hold extensive model states during extended computation periods. Its 2450 GB/s bandwidth and RoCE Ethernet interconnect further support distributed setups where the 600W TDP remains acceptable for sustained operation.

The RTX 3080 fits tasks that utilize its FP16 dense performance of 59.5 TFLOPS or FP32 performance of 29.8 TFLOPS within a 320W TDP limit. Its PCIe form factor and 10 to 12 GB GDDR6X memory align with compact deployments that do not exceed these capacity thresholds.
