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.

Otázky k tomuto produktu

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.
