Performance Analysis
Compute disparities define these GPUs' capabilities: the B300 achieves 2250 TFLOPS in FP16 for accelerated AI training and inference, far exceeding the RTX 2080 Ti's 10.1 TFLOPS. This delta enables the B300 to process massive models in hours that would take days on the older card. FP32 performance at 90 TFLOPS on B300 versus 10.1 TFLOPS supports general simulations better, though the ratio shrinks. The B300's FP8 at 4500 TFLOPS further optimizes low-precision inference for LLMs. Memory specs amplify real-world impacts: 288 GB HBM3e on B300 sustains large batch sizes in training, avoiding out-of-memory errors common with RTX 2080 Ti's 11 GB limit. Bandwidth of 12000 GB/s versus 616 GB/s ensures rapid data throughput, reducing bottlenecks in data-heavy workloads like fine-tuning. Power draw reflects scale: B300's 1200W TDP suits dense clusters, while 215W fits edge or desktop use.

When to Choose the B300 SXM6
Opt for the B300 SXM6 in large-scale AI deployments: its 288 GB VRAM handles billion-parameter LLMs, and 2250 TFLOPS FP16 speeds training epochs dramatically. Scenarios include enterprise inference serving or multi-GPU clusters via NVSwitch and NVLink, where 12000 GB/s bandwidth maximizes throughput. At $2.45 per hour starting price, it justifies costs for production workloads demanding HBM3e capacity.
When to Choose the RTX 2080 Ti
Select the RTX 2080 Ti for cost-sensitive prototyping: 8 to 11 GB VRAM suffices for small models, and $0.06 per hour pricing enables extended experimentation. It excels in gaming, light Stable Diffusion, or personal fine-tuning where 10.1 TFLOPS FP16 meets needs without overkill. PCIe form factor and 215W TDP integrate easily into single-node setups.
Use Cases
B300's 288 GB VRAM and 2250 TFLOPS FP16 support massive datasets and models. RTX 2080 Ti's 11 GB limit causes frequent failures.
4500 TFLOPS FP8 and 12000 GB/s bandwidth on B300 enable high-throughput serving. RTX 2080 Ti struggles with batch sizes beyond small queries.
