Entry-level workstation GPU

The Lenovo Quadro K420 is a 1 GB DDR3 SDRAM graphics card built for professional 2D applications and multi-monitor desktop setups. It connects through a PCI Express 2.0 x16 slot and fits a standard plug-in card form factor.

Suits basic display needs, not compute

This card suits users who need reliable driver support for legacy workstation software or dual-screen office productivity via one DisplayPort and one DVI-I output. It is not for buyers who want 3D rendering acceleration, GPU compute performance or modern API features beyond the Kepler architecture.

1 GB DDR3 frame buffer

The single gigabyte of DDR3 memory determines whether the K420 can hold your working dataset; larger models or textures will exceed this capacity and force fallback to system memory.

Questions about this item

What length and height clearance does the 6.3 by 2.7 inch K420 card need inside the case?

The plug-in card measures 6.3 inches long, 2.7 inches high and 0.5 inches wide, so verify your chassis has at least that much free space in a full-height PCIe slot.

How is the PCI Express 2.0 x16 card seated, and what step is often missed?

Align the gold edge connector with the PCIe 2.0 x16 slot, press firmly until the retention latch clicks, then attach the DisplayPort or DVI-I cable before powering on.

When should the 1 GB DDR3 SDRAM graphics card be replaced?

Plan replacement when driver updates no longer support the Quadro K420 chipset or when professional applications require more than 1 GB of video memory.
