Lenovo RTX A4000 16GB Workstation GPU

The Lenovo RTX A4000 is a professional graphics card with 16GB of GDDR6 memory designed for creative and technical workloads. It connects via a PCI Express x16 interface and operates at a 2.0 GHz core clock. The card features a dual-slot active cooler with a fan and draws power through a single 6-pin PCIe connector. It provides four DisplayPort outputs for multi-monitor setups.

Suited for multi-display creative work.

This card suits professionals driving up to four displays from a compact 9.5-inch form factor with 448GB/s peak memory bandwidth. It fits workflows needing hardware-accelerated ray tracing and AI features within a 140W power envelope. Buyers who need more than 16GB of video memory for large datasets or simulations should look at higher-capacity alternatives. Systems without a PCIe 6-pin power connector cannot support this card.

Sustained 140W output with active cooling

Under continuous load the card maintains its 140W maximum graphics power through the dual-slot fan cooler. The single 6-pin connector delivers stable current for extended rendering or compute sessions without relying on brief boost behaviour. Peak memory bandwidth of 448GB/s remains available during prolonged operations. The 9.5-inch length allows airflow in dense workstation chassis while dissipating heat consistently.

Questions about this item

What power connector does the RTX A4000 need from my PSU?

The card draws up to 140W through a single 6-pin PCIe power connector.

Will the dual-slot RTX A4000 fit next to my existing PCIe x16 devices?

At 9.5 inches long and dual-slot wide, it occupies two rear brackets and one x16 slot; verify case clearance and motherboard spacing.

How can I confirm the 16GB GDDR6 memory is running at full 448GB/s bandwidth?

Run GPU-Z or NVIDIA SMI after driver install; both report memory clock and achieved bandwidth matching the 448GB/s spec.
