Performance Analysis
The B300 lists FP16 dense performance at 2250 TFLOPS and FP16 with sparsity at 4500 TFLOPS while the RTX 2060 provides no published FP16 value. This gap in dense FP16 means the B300 can handle matrix operations at a scale that remains unavailable on the RTX 2060 for training or inference steps. Memory bandwidth of 8000 GB/s on the B300 versus 336 GB/s on the RTX 2060 directly limits batch sizes because data movement speed determines how many tokens or samples fit in a single pass. FP32 comparison places the B300 at 75 TFLOPS against the RTX 2060 at 6.5 TFLOPS so any workload that stays in single precision still favors the B300 by the ratio of those two numbers.

When to Choose the B300
The B300 suits LLM training runs that need 262 to 288 GB HBM3e memory and 2250 TFLOPS FP16 dense throughput. Its 8000 GB/s bandwidth and NVLink interconnect also support large scale inference where the 1400W TDP is acceptable.
When to Choose the RTX 2060
The RTX 2060 fits scientific computing tasks that stay within 6 to 12 GB GDDR6 memory and require only 6.5 TFLOPS FP32 at a 160W TDP. Its PCIe form factor matches standard consumer or small workstation builds.
Use Cases
The B300 supplies 2250 TFLOPS FP16 dense and 262 to 288 GB memory that the RTX 2060 cannot match.
The B300 provides 4500 TFLOPS FP16 with sparsity and 8000 GB/s bandwidth for sustained token generation.
The B300 75 TFLOPS FP32 rating and large HBM3e capacity allow bigger adapter layers than the RTX 2060 6.5 TFLOPS FP32.
The RTX 2060 160W TDP and PCIe form factor suffice for 6 to 12 GB workloads without the 1400W requirement of the B300.
The RTX 2060 delivers 6.5 TFLOPS FP32 at 160W TDP for modest simulations that fit in 6 to 12 GB GDDR6.
Frequently Asked Questions
What is the FP32 performance difference between the B300 and the RTX 2060?▾
The B300 lists 75 TFLOPS FP32 while the RTX 2060 lists 6.5 TFLOPS FP32 so the B300 rating exceeds the RTX 2060 rating by more than ten times.
What power draw does the B300 require compared with the RTX 2060?▾
The B300 carries a 1400W TDP and the RTX 2060 carries a 160W TDP.
Can the RTX 2060 run FP16 workloads at the same level as the B300?▾
The RTX 2060 has no published FP16 figure so direct comparison is not possible while the B300 states 2250 TFLOPS FP16 dense.
What form factors do these GPUs use?▾
The B300 uses an SXM6 form factor and the RTX 2060 uses a PCIe form factor.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the B300 and the RTX 2060. Dense and sparse throughput are listed separately.
- Prices and availability are live: every offer shown is an in-stock, on-demand listing from a provider we track, rechecked every minute.
- The written comparison (overview, performance notes, when to choose each card, verdict, use cases and FAQ) was drafted with an AI model from the specification table above and passed an automated check that rejects any figure not in that table. It was last generated on . It contains no prices; those are always read live.
