Intel Gaudi 2 vs RTX 4080 SUPER

The Gaudi 2 outperforms the RTX 4080 SUPER in raw compute by nearly 9 times, delivering 420 TFLOPS FP16 and FP32 compared to 48.7 TFLOPS. This delta accelerates deep learning training and inference, where FP16 handles mixed-precision workloads efficiently; larger models train faster on Gaudi 2 due to sustained high throughput. Both GPUs maintain equal FP16 to FP32 ratios, supporting balanced tensor and matrix operations without precision bottlenecks.

Memory specs define real-world limits: Gaudi 2's 96 GB HBM2e versus 16 GB GDDR6X allows batch sizes up to 6 times larger, reducing overhead in transformer training. Its 2460 GB/s bandwidth versus 717 GB/s minimizes data starvation, enabling 3.4 times faster memory-bound tasks like LLM fine-tuning. Lower bandwidth on RTX 4080 SUPER constrains large-batch inference, often requiring model sharding.

Power efficiency varies: Gaudi 2's 600W TDP yields 0.7 TFLOPS per watt, slightly below RTX 4080 SUPER's 0.15 TFLOPS per watt at 320W. For dense deployments, Gaudi 2 maximizes FLOPS density, while RTX 4080 SUPER excels in low-power edge scenarios.

Opt for Gaudi 2 in large-scale LLM training or inference requiring over 16 GB VRAM. Its 96 GB HBM2e supports billion-parameter models in single-GPU setups, with 2460 GB/s bandwidth sustaining high batch sizes. At $0.91 per hour average, it justifies cost for enterprises needing 420 TFLOPS FP16 performance via Ethernet scaling.

Select RTX 4080 SUPER for budget-conscious prototyping, fine-tuning small models, or Stable Diffusion generation. Its 16 GB GDDR6X and $0.17 per hour pricing from $0.32 average suit individual developers, with 320W TDP enabling dense PCIe clusters. Lower 48.7 TFLOPS suffices for sub-16 GB workloads without HBM premiums.
