The component in question is a mobile graphics processing unit (GPU) from NVIDIA’s RTX 40-series lineup. Based on the manufacturer prefix "jh" (likely referring to OEMs like Tongfang or Clevo, often rebranded by companies like Eluktronics, XMG, or Schenker) and the "m3" chassis designation, this is a high-performance component typically found in mid-range to high-end gaming laptops.
In the context of 2025, this card is thoroughly obsolete for gaming. The 48 CUDA cores and 512MB of VRAM are far below the minimum requirements for virtually any modern title released after 2015.
Because the PCB marking doesn't identify the chip itself, use these steps to find the actual model: jh m3 94v-0 graphics card
This is where confusion becomes dangerous. The same "JH M3" board design has been used for more capable graphics cards, and unscrupulous sellers often exploit this to trick buyers.
These parts are primarily found as "tested and working" used items on marketplaces like eBay or AliExpress. The component in question is a mobile graphics

Once you cut through the branding and safety labels, the hardware underneath the "JH M3 94V-0" shell is actually quite specific. The technical data consistently points to an (or its immediate predecessor, the 510). The 48 CUDA cores and 512MB of VRAM
To find the exact specifications, look for a small white sticker on the back of the PCB. This sticker usually contains the actual model number (e.g., "P4E" or "V259").
The JH M3 94V-0 graphics card is designed to be overclocked, allowing users to push its performance to the limit. The graphics card features a robust cooling system, including:
