Blackwell graphics for a compatible professional workstation
16 GB GDDR7 ECCBlackwell architecture4× mini-DisplayPort70 W board power
The Lenovo 4X61T95638 is an RTX PRO 2000 Blackwell graphics-card kit for professional workstation upgrades. Its 16 GB ECC GDDR7 memory, hardware ray tracing and AI acceleration support design, visualisation and supported local compute workflows. Four mini-DisplayPort outputs provide multi-display connectivity in a compact, actively cooled GPU design.
Best For: Professional users upgrading a verified compatible Lenovo workstation for CAD, 3D visualisation, supported GPU compute or multiple displays.
Before you order: Check the exact workstation, chassis clearance, bracket, riser, firmware and system power configuration before ordering this Lenovo OEM kit. The GPU uses PCIe 5.0 ×8 electrically and a full-length PCIe connector. Mini-DisplayPort cables or suitable adapters may be needed; they are not listed in the supplied contents. This is a graphics card, not a complete PC or a software licence.
What's in the Box
- One graphics card and one riser card.
- Two brackets, five screws, quick start guide and warranty poster, as listed by Lenovo.
- Workstation, monitors, display cables/adapters and application licences are separate.
What It Means in Practice
- Keep larger design assets and GPU workloads in 16 GB of dedicated ECC GDDR7 memory; required capacity depends on the application.
- Use compatible professional drivers and check your application’s GPU support or certification for its exact version.
- Connect displays using the four mini-DisplayPort outputs and suitable cables or adapters.
- Verify the Lenovo machine configuration and install with the correct bracket/riser and adequate airflow.
What Will Not Work
- This exact Lenovo kit does not imply universal compatibility with every desktop or small-form-factor chassis.
- The outputs are mini-DisplayPort, not full-size DisplayPort, HDMI or USB-C.
- A 70 W GPU rating is not the minimum power-supply rating for the complete computer.
- AI, rendering and ray-tracing performance depend on the application, drivers, workload and other system components.

Frequently Asked Questions
Is this the older RTX 2000 Ada?
No. The exact 4X61T95638 is RTX PRO 2000 Blackwell with GDDR7 memory.
Does it fit any low-profile desktop?
Compatibility must be verified for the exact computer and Lenovo kit. A compact GPU alone does not establish bracket, riser or chassis fit.
Are HDMI adapters included?
Lenovo does not list display cables or adapters in the package contents. Plan suitable mini-DisplayPort connections separately.
Is 70 W enough for the whole system?
No. That figure is maximum GPU board power; the complete workstation has separate power requirements.
Singular Expert Insight
Treat this as an OEM workstation upgrade rather than choosing on GPU name alone. The exact Lenovo kit and machine configuration matter as much as 16 GB of VRAM. Confirm physical installation and display cabling, then check the professional application and driver combination you intend to use.
Buyer’s Guide
✓ Buy it if You need a compatible Lenovo professional GPU upgrade with 16 GB ECC memory and four mini-DisplayPort outputs.
✕ Skip it if You need a complete computer, HDMI outputs built into the card or guaranteed compatibility without checking the workstation.
→ Also consider Workstation model, riser and bracket, available slots and cooling, system power, display adapters and supported application drivers.
