Stability AI Claims Intel Gaudi 2 is Faster than NVIDIA H100
In a recent blog post titled “Behind the Compute,” Stability AI, unveiled shocking findings regarding the performance of Intel Gaudi 2 accelerators compared to NVIDIA’s H100 in training and inference of its upcoming image generation model Stable Diffusion 3. Stability AI’s text-to-image model demonstrated promising results in the performance analysis. Utilising the 2B parameter multimodal diffusion transformer (MMDiT) version of the model, Stability AI compared the training speed of Intel Gaudi 2 accelerators with NVIDIA’s A100 and H100. On 2 nodes configuration, Intel Gaudi 2 system processed 927 training images per second, 1.5 times faster than NVIDIA H100-80GB. Further increasing the batch size to 32 per accelerator in Gaudi 2 resulted in a training rate of 1,254 images/sec. On 32 Nodes Configuration, the Gaudi 2 cluster processed over 3x more images per second compared to NVIDIA A100-80GB GPUs, despite A100s having a highly optimised software stack. On inference tests with the Stable Diffusion 3 8B parameter model, Gaudi 2 chips offered similar inference speed to NVIDIA A100 chips using base PyTorch. However, Stability AI admitted that with TensorRT optimisation, A100 chips produced images 40% faster than Gaudi 2, but Stability AI anticipates Gaudi 2 to outperform A100s with further optimisation. This can be further contented with the upcoming GH200 processors that might be announced at GTC 2024 this month.

Intel has also launched its Gaudi 3 AI accelerator which would make this competition even interesting in the future. Moreover, Stable Beluga 2.5 70B, Stability AI’s fine-tuned version of LLaMA 2 70B, showcased impressive performance on Intel Gaudi 2 accelerators. Running the PyTorch code out of the box on 256 Gaudi 2 accelerators, Stability AI measured an average throughput of 116,777 tokens/second. Gaudi 2 demonstrated a 28% faster performance compared to NVIDIA A100 in inference tests with the 70B language model, generating 673 tokens/second per accelerator.
But only without TensorRT Optimisation.
