Peak bandwidth 768GB/s
Use in calculator

CUDA backend; use a runtime build that supports this GPU generation.

Specifications and setup

Memory
48 GiB GDDR6 ECC
Connection
PCIe 4.0 x16; optional two-card NVLink, 112.5 GB/s bidirectional
Runtime
CUDA backend; use a runtime build that supports this GPU generation.
Power
300 W. Maximum/reference board power; excludes the host system and is not measured inference power
Bandwidth basis
Manufacturer peak memory bandwidth; not a measured sustained rate or a token/s estimate.
System reserve
Planner assumption: 1 GiB per device for driver/display and allocation headroom. Runtime buffers are modeled separately; actual free memory must be checked.

Model fit at Q4 and 8K

One request, FP16 conversation cache, default reserves. “Not verified” means the model’s cache formula needs more research.
