If I’m going with a 5060ti egpu does it really matter if I get the legion go s z1e or the legion go 2. I love the OLED and other LEGO 2 specs but I can get the go s faster and for around $700.
Just got my new TH5P4 egpu from Aliexpress. I use it on my Legion Go 1 (i know its USB4 only on the Lego port) with an GeForce 3060ti installed and a 700w psu.
Compared to my previous TH3P4G3 the new TH5P4 needs a high quality cable if you play with Legion Go.
I tried several cheaper cables which were working with TH3P4G3 but for TH5P4 i noticed disconnects very often.
Finally i bought a 2m active , Intel-certified TB4 cable by manufacturer Cable Matters which is Half of the costs compared to an Apple usb4 cable but still three times more expensive as normal passive cables.
Performance is really Good on the Lego playing Crimson Desert on high settings.
I don‘t expirienced issues with vents always in full mode even in idle state.
The TH3P4 would be sufficient for the Lego but I made a good deal on AliExpress , so I decided to buy the TH5P4 for Future devices with TB5 support.
Just got this last week and loving how portable it is when needed. No real errors or setup issues. Just plug in and play.
AORUS RTX 5060ti TB5 AI box with my lenovo legion go 2
I've got a mini PC with Occulink, I've got a RTX 3070ti, I've got a spare ATX power supply. I don't need anything portable and I can 3d print a stand.
What's the cheapest way I can connect this altogether? It doesn't have to be pretty.
I'm getting a dock for my legion go and I saw reviews for the EG02 and DEG2. A little pricey. I also have a mini PC with oculink so this would be sort of a multi use case.
Just wondering if it's safe to buy used? I'm actually seeing some good prices for used DEG2 and EG02 on mercari and eBay currently.
I have a ASUS ZenBook Flip 15 and I’ve been wanting to play the new horizon game but the internal GPU isn’t cut out for the game. Would a eGPU be compatible with my laptop and if so what would you recommend using?
The model is the one with the OLED screen, 32GB DDR5 and the Ryzen 7 350.
Basically what I said in the title. I am very interested in doing the mod as I would like to one day play GTA6 or TES6 without losing a lot of performance as would happen if I were to use the USB4 port. I would appreciate any tips!
Hey, I really need help with an eGPU USB4 setup 😭
Setup:
- Ryzen 7 8845HS + AMD Radeon 780M iGPU
- NVIDIA RTX in a USB4 eGPU dock
- Windows 11
Problem:
- RTX fans spin normally
- dock is powered and stable
- no more blinking/disconnecting
- BUT Windows still does not detect the RTX under “Display adapters”
At first I had:
- “Unknown device”
- USB4\VID_0000&PID_0000
- error code 45
Things I already tried:
- DDU in safe mode
- reinstalling AMD/NVIDIA drivers
- disabling PCI Express Link State Power Management
- disabling AMD iGPU
- full shutdowns/restarts
- reconnecting everything in different orders
- BIOS checks
- reinstalling PCI/USB devices
Current situation:
- no more “unknown device”
- GPU fans spin continuously
- Device Manager no longer refreshes every 5 sec
- but the RTX still doesn’t appear anywhere
The dock uses an ASM246X controller and runs through USB4.
If anyone has already had this issue or knows a fix, please help 🙏
Has anyone else here used an eGPU with Forza Horizon 6 yet? I have tried everything to increase the FPS including reinstalling drivers, but I seem to be stuck at 46 FPS with the graphical settings on high. Short of doing a fresh windows install, I'm unsure what else to do to improve it.
Has anyone else experienced this and found a fix?
CPU seems like it would pair great with an eGPU. It’s a Dell Precision 5490 and has thunderbolt 4, so it’s possible.
Anyone recommend a good one?
All the ones on UK Amazon look and feel like they were made by the lowest bidder out of chicken wire and electrical tape.
would it be possible with a m.2 to oculink?
Hey everyone!
My university had a hackathon and I took the opportunity to test out the portability of my egpu setup. The theme of the hackathon was building an agent, and we ran all the models for our project locally. Settled on gemma4:26b, fit inside my 7900xt no problem. Finished 5th place out of 40 teams:)
I'm looking for a laptop for college which will run with a gigabyte aoeus ai box 5060ti (16gb vram). Is there any sureshot way of knowing if a laptop supports eGPUs because I have been reading that thunderbolt 4/usb4 doesn't always mean egpus are supported ...
I have been trying to find out if the ASUS Zenbook 14 (2026),Intel Core Ultra 9 285H (UX3405CA-QL1016WS) will support it but the model was just released and I don't think people have tried it... Also it would be nice to know how to differentiate egpu compatible laptops from non egpu compatible laptops incase I decide to upgrade my laptop anytime soon...
Hi everyone. I recently buyed the NBA 2k26 and a new DLC for Cities Skylines. The problem is after just a few minutes on nba and in the loading screen of Cities Skylines the eGPU drops to 0% of usage, weird artifacts appears on one of the monitors (always the one with steam).
I've been testing my Pangolin + eGPU 5060ti combo for almost a month, trying to make it fully stable so I could document it here on reddit, and it's been working really well, until yesterday when this problem started. I haven't tried any other games since. If anyone of you guys have a good idea of what's going on I would love to hear it.
I'm using pop_os 22.04 and nvidia drivers 590 series.
Hey everyone,
I've been working on a Decky Loader plugin called eGPUBridge that solves a specific problem: managing external GPU display output on SteamOS handhelds.
The problem: When you connect an eGPU via USB4/Thunderbolt to a handheld running SteamOS (Legion Go, ROG Ally, etc.), switching between the internal
screen and the external display attached to the eGPU is a pain. You end up tinkering with config files, restarting sessions, or rebooting.
What eGPUBridge does:
- Auto-detects eGPU via USB4/Thunderbolt
- One-button switching between internal display and external TV
- Choose which GPU renders for the external display (eGPU vs integrated)
- Optional TV control — Wake-on-LAN, ADB, CEC (turn your TV on/off)
- Emergency hotkey to recover if something goes wrong
- Read-only USB4 dock status
How it works under the hood:
eGPU detection:
- Scans /sys/class/drm/card[0-9] — all DRM cards in the system
- Reads PCI vendor/device IDs from sysfs (/sys/class/drm/cardX/device/vendor, device)
- Built-in GPU is identified by the boot_vga=1 flag — everything else is considered external
- AMD GPUs recognized by vendor ID 0x1002, model name comes from lspci
- Not hardcoded to any specific hardware — works with any eGPU over USB4/Thunderbolt
Display detection:
- EDID of the monitor is read directly from /sys/class/drm/cardX-CONNECTOR/edid (binary data, monitor name parsed from the 0xFC descriptor)
- Connection status: connected / disconnected from sysfs
- Supported resolutions and refresh rates: parsed from modetest -c output (filters modes from 720p 50Hz and up)
- Priority: HDMI first (practical use case), then the rest
Display switching:
- Does NOT patch the system /usr/lib/steamos/gamescope-session file directly
- Uses plugin config files: output_order.conf (output order), prefer_vk_device.conf (GPU selection), gamescope_mode.conf (resolution)
- Gamescope is launched with parameters -O HDMI-A-1 (external) or -O eDP-1 (internal)
- --prefer-vk-device 1002:7550 tells gamescope which GPU to use for rendering
Internal panel shutdown (when running on TV):
- DPMS Off via modetest -w connectorID:DPMS:3 — monitor goes to "no signal" instead of black screen
- Backlight is saved and turned off (/sys/class/backlight/amdgpu_bl0/brightness = 0)
- Framebuffer blank + unbind fbcon — removes boot logo artifacts
TV control:
- Wake-on-LAN: magic packet sent to the TV's MAC address
- ADB: connects over IP, checks screen state (dumpsys display | grep mWakefulness)
- CEC: control via HDMI CEC protocol
- TV network status detected via ping (doesn't flood logs)
- TV config: /home/deck/.config/egpubridge-tv.conf (IP, MAC, ADB — not published)
PCIe link status:
- Speed and link width read from /sys/bus/pci/devices/ADDR/current_link_speed and current_link_width
- Fallback: parsing lspci -vv (LnkSta: line)
- Shows real USB4/TB throughput (e.g. 32GT/s x4)
Safety:
- Atomic config writes (write to .tmp first, then os.replace)
- Automatic backup of original gamescope-session before any changes
- Log rotation (max 2MB, keeps 700KB)
- Plugin does NOT restart SDDM for normal switching
Tested on: Lenovo Legion Go S (SteamOS) + AMD eGPU via ASMedia USB4 bridge. Should work on other handhelds with SteamOS and USB4/Thunderbolt — uses
generic detection via sysfs/DRM.

It's at v0.2.alfa — very early. I'd really appreciate it if anyone with an eGPU setup on SteamOS could try it out and report back. Even if it works —
that's valuable info. If it doesn't — even more valuable, because right now I only have one hardware combo to test on and I can't reproduce errors or edge
cases on other devices. Logs, screenshots, dmesg output — anything helps.
What hardware combos are you running? What features would you want?
Heya,
I am looking for someone who can maybe chip in with some knowledge about performance metrics. I have been given a Lenovo Yoga 9i 16" with an Ultra 9 285H, Laptop 5070, and 64GB RAM for work. Its equipped with: 2 x USB-C (Thunderbolt™ 4/USB4 40 Gbit/s) with Power Delivery 3.0 and DisplayPort 2.1
For my 32:9 Monitor (5120x1440), the Laptop 5070 is still struggling with some Games, i.e. Sims, so I was thinking about getting a 5080 with a TB4 Dock. I tried to read up on it but only did find guesstimates.
Does somebody know what performance increase I could expect from a setup like that ?
In a Desktop Environment the 5080 is roughly 46% faster compared to the Laptop 5070, but the topic of PCIe Lanes bottleneck seems to be the biggest topic.
Thanks.
1st image is with my new AG02 dock.
The 2nd image shows how much performance i was costing myself using an outdated Razer x Chroma TB3 eGPU dock .
According to timespy this is better than the "worlds best" for the z2e + 4070super....i just don't know how to submit mine.
