Lenovo NVIDIA RTX A400 4 GB GDDR6 Graphics Card 4X61Q73040

At the heart of this card is the NVIDIA RTX A400 graphics processor. As a discrete adapter, it takes graphics work off the system's main processor and handles it on its own chip with its own memory. That is the main reason to choose a separate card over integrated graphics. For detailed performance figures such as core counts or clock speeds, check NVIDIA's documentation, because Lenovo does not include them in this listing.

The card has 4 GB of GDDR6 memory that belongs to the graphics processor alone. Because textures, frame data and visual workloads stay in the card's own memory, the GPU doesn't have to borrow from your system RAM. That leaves more of your main memory free for applications. GDDR6 is the memory type listed by the manufacturer, and the 4 GB capacity is one of the key figures to compare when you weigh up graphics cards.

The card connects through a PCIe 4.0 x8 interface. Before you buy, check that your desktop has a free PCIe slot that can take the card, and confirm the slot generation and lane support in your motherboard or system manual. Clear interface details like these make it easier to judge compatibility in advance, which saves you time and avoids returns.

Lenovo sells this card under part number 4X61Q73040 in its Graphics Card product family. A precise manufacturer code makes it simple to cross-check against compatibility lists, IT procurement sheets or support documentation. It also helps when you need to order the same card again for several identical machines, so there is no guessing between similar-sounding models.

With a net weight of 0.2 kg, the card is easy to handle during installation and puts little load on the PCIe slot. For a quick upgrade, that means less fuss: open the case, seat the card, secure it and close up. The manufacturer does not list physical dimensions or the bracket type, so measure the space inside your case and check the slot layout before ordering.

Adding a discrete graphics card is one of the simplest upgrades you can make to a desktop. It gives the system a dedicated graphics processor and memory without replacing the whole machine. The card contains no embedded battery, so there is no battery to maintain. Lenovo does not list display outputs, power connectors or supported operating systems here, so check these against your setup before you buy.

This card suits buyers who want a well-documented NVIDIA RTX A400 card with 4 GB GDDR6 under a clear Lenovo part number. It fits office or IT upgrades, refreshing an existing desktop, or standardising graphics across several machines. If you need dedicated graphics memory and a PCIe 4.0 x8 connection, this card covers the essentials at a good price.
