Lenovo 4X61T95636 graphics card NVIDIA RTX PRO 4000 Blackwell 24 GB GDDR7

Lenovo 4X61T95636 is a discrete NVIDIA-based graphics card with 24 GB of GDDR7 memory on a 192-bit memory bus. The card connects via a PCI Express x16 5.0 interface and supports high-resolution output up to 7680×4320. It is designed for workstation-class GPU workloads, content creation and demanding rendering tasks, and includes active cooling in a compact single-slot form factor with an approximate weight of 1.018 kg.

Advantages

This graphics card combines a large 24 GB GDDR7 frame buffer and a 192-bit memory bus to provide the capacity and throughput needed for large datasets, multi-application workflows and high-resolution rendering. The PCIe 5.0 x16 interface offers increased host bandwidth compared with previous generations. Active cooling helps maintain sustained performance under load while the compact single-slot profile and moderate weight make installation in space-constrained systems straightforward. Compatibility with modern graphics APIs ensures support for professional applications that rely on DirectX 12.0 and OpenGL 4.6.

Suitable for

• High-resolution rendering and video post-production up to 7680×4320
• 3D modelling and CAD workflows that require large GPU memory
• Data-heavy visualization and multi-application workstation use
• GPU-accelerated compute tasks in professional environments
