Performance Analysis
The B300 delivers 2250 TFLOPS in dense FP16 and 75 TFLOPS in FP32. The Gaudi 2 does not publish FP16 or FP32 figures. Higher memory bandwidth of 8000 GB/s on the B300 versus 2450 GB/s on the Gaudi 2 supports larger batch sizes during both training and inference passes. The B300 also lists 4500 TFLOPS dense FP8 and 13500 TFLOPS dense FP4. These dense figures allow direct comparison only against other dense measurements. The 262 to 288 GB memory capacity on the B300 enables handling of models that exceed the 96 GB limit of the Gaudi 2.

When to Choose the B300
The B300 suits workloads that require the 262 to 288 GB memory capacity and 8000 GB/s bandwidth. Large model training sessions benefit from the 2250 TFLOPS dense FP16 rating and the 1400W TDP configuration in SXM6 form factor with NVLink interconnect.
When to Choose the Gaudi 2
The Gaudi 2 suits deployments that operate within the 600W TDP limit and the OAM form factor. Workloads that fit inside 96 GB memory and use RoCE Ethernet or PCIe 4.0 interconnects align with the Gaudi 2 specifications.
Use Cases
The B300 supplies 262 to 288 GB memory and 8000 GB/s bandwidth that exceed the 96 GB and 2450 GB/s of the Gaudi 2.
The B300 provides 2250 TFLOPS dense FP16 and 4500 TFLOPS dense FP8 that support larger batch processing than the Gaudi 2 allows.
The B300 memory range of 262 to 288 GB accommodates fine tuning of models that surpass the 96 GB capacity of the Gaudi 2.
The B300 bandwidth of 8000 GB/s and dense FP16 rating of 2250 TFLOPS enable higher throughput than the Gaudi 2 specifications support.
The B300 FP32 rating of 75 TFLOPS combined with 8000 GB/s bandwidth addresses compute needs beyond the published limits of the Gaudi 2.
