48GB GDDR6 AI Accelerator for Data-Centres

The PNY NVIDIA A40 is a new 48GB GDDR6 accelerator card built on the Ampere architecture. It delivers 10,752 CUDA cores, 336 third-generation Tensor cores and 84 second-generation RT cores. A 384-bit memory interface provides 696GB/s bandwidth across 48GB of ECC-protected GDDR6 memory. The PCIe 4.0 x16 bus and NVLink at 112.5GB/s bidirectional speed enable multi-GPU scaling for large-model training and inference workloads.

Suited for High-Memory AI Workloads.

This card targets researchers and engineers training large language models, running high-resolution rendering or performing scientific simulation where 48GB of frame buffer and ECC are required. The passive heatsink demands server chassis with directed high-volume airflow; it will not operate reliably in workstations or servers that rely on active GPU fans. Buyers needing active cooling, a lower memory footprint or a single-slot form factor should evaluate alternative accelerator designs.

384-Bit GDDR6 Bus Determines Model Fit

The single specification that decides fit is the 384-bit GDDR6 memory interface delivering 696GB/s bandwidth. That width and bandwidth define the maximum model size and batch throughput the card can sustain without offloading to system memory. If the target workload fits within 48GB and can saturate the 384-bit bus, the A40 matches; if the dataset exceeds 48GB or requires higher memory bandwidth, a different accelerator class is needed.
