A40 vs Gaudi 2

Dense FP16 performance stands at 149.7 TFLOPS on the A40 and supports training and inference operations that rely on this compute level. The FP32 performance of 37.4 TFLOPS on the A40 supplies a reference point for single precision calculations. The Gaudi 2 does not publish FP16 or FP32 figures so ratios remain limited to the A40 values alone. Memory bandwidth of 2450 GB/s on the Gaudi 2 exceeds the 696 GB/s on the A40 and permits larger batch sizes in bandwidth constrained workloads. The 96 GB VRAM capacity on the Gaudi 2 doubles the 48 GB on the A40 and combines with the elevated bandwidth to accommodate models that exceed the A40 memory limit. TDP differences of 600W on the Gaudi 2 versus 300W on the A40 further shape system level efficiency calculations.

The A40 serves workloads that require published dense FP16 performance of 149.7 TFLOPS and INT8 dense performance of 299.3 TOPS. Its 300W TDP and PCIe form factor with NVLink interconnect align with deployments that prioritize lower power draw and established server compatibility.

The Gaudi 2 serves workloads that require 96 GB VRAM and 2450 GB/s memory bandwidth to process larger data volumes. Its OAM form factor and RoCE Ethernet interconnect suit environments where memory capacity and bandwidth take precedence over published tensor performance figures.
