Gaudi 2 vs RTX A4000

The RTX A4000 delivers FP16 performance of 153.4 TFLOPS with sparsity and FP32 performance of 19.2 TFLOPS. No corresponding tensor figures appear for the Gaudi 2 because the vendor has not published them. Memory bandwidth of 2450 GB/s on the Gaudi 2 supports larger batch sizes than the 448 GB/s bandwidth of the RTX A4000 during both training and inference passes. The 600W TDP of the Gaudi 2 versus the 140W TDP of the RTX A4000 affects sustained operation in power constrained environments. Workloads that fit within 20 GB can utilize the published 153.4 TFLOPS with sparsity on the RTX A4000 while larger models require the 96 GB capacity of the Gaudi 2.

The Gaudi 2 suits deployments that require 96 GB HBM2e memory to hold models exceeding 20 GB. Its 2450 GB/s bandwidth further enables larger batch processing than the 448 GB/s available on the RTX A4000. Organizations running memory intensive tasks select the Gaudi 2 when OAM form factor and RoCE Ethernet interconnect align with existing infrastructure.

The RTX A4000 fits environments limited to 140W power envelopes and PCIe slots. Its published FP16 performance of 153.4 TFLOPS with sparsity supports workloads that remain within 16-20 GB GDDR6 capacity. Teams prioritizing lower TDP and standard PCIe interconnect choose the RTX A4000 for compact inference or fine tuning jobs.
