eGPU compatibility

[Envy959]

Currently need more VRAM to run Topaz photo editing AI model software and need a minimum of 8GB dedicated VRAM to do so. Have exhausted trying to upgrade the installed nvidia GeForce RTX 3050 laptop GPU (4GB VRAM) to a 3080 (8GB VRAM) card which I cannot find anywhere.  Would like to know what compatible options/brands for setting up an eGPU I have for my HP Envy 34-c1000 (4G584AV); serial Edited I do have a Thunderbolt 4 USB-C port on my PC.

Thanks for any insight on this!

Hi @Envy959,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I’m sorry you’re going through this; I understand the concern and don’t worry I’ll help you with this. 

To help me understand the situation better, could you please share a bit more information?

 Please let me know:

1. Thunderbolt / USB‑C Port:
   • Is the port you plan to use Thunderbolt 4 (or at least Thunderbolt 3) rather than just a standard USB‑C port?
   • Does this port support Power Delivery (PD) i.e., can it provide 100W or more to the eGPU enclosure?
2. eGPU Enclosure (Chassis):
   • Do you already have an eGPU chassis (such as from GMtek, Razer, Akitio, Sonnet, etc.)?
   • If yes which model / brand, and what is its power supply rating (wattage)?
   • If no are you open to buying a compatible eGPU enclosure + GPU together?
3. GPU Requirements:
   • Do you specifically want an NVIDIA GPU (e.g. RTX 3080), or are you okay with a different GPU with at least 8 GB VRAM?
   • What’s your target performance  for example, AI model inference, training, heavy editing?
4. Power and Cooling Considerations:
   • Do you have a good power outlet and enough space to accommodate an eGPU box?
   • Is noise/heat a concern?

 Key Compatibility & Troubleshooting Considerations for eGPU Setup

• Thunderbolt Bandwidth:
  For AI and GPU-intensive workloads, having a real Thunderbolt 3 or 4 connection is important for performance and stability.
• Enclosure Power Supply:
  The eGPU enclosure should have a sufficient wattage PSU to support a high‑end GPU plus power for the laptop (if powering through the enclosure).
• GPU Size / Slot Compatibility:
  Ensure the graphics card fits physically inside the eGPU chassis (length, width, height).
• Driver Support:
  Use up-to-date NVIDIA drivers that support external GPU setups.
• Cooling / Heat Management:
  High-VRAM GPUs (like RTX 3080) run hot, so make sure your enclosure has good ventilation.

I hope this helps.
