  1. PCI-E 2.0 X16 = PCI-E 3.0 X8. PCIe Generation Bandwidth PCIe Gen 1 x16 8 Gbps PCIe Gen 2 x16 16 Gbps PCIe Gen 3 x16 32 Gbps. Intel and Nvidia have been slow in adapting to PCIe gen 4.0 but AMD processors and GPUs already support the latest PCIe 4.0 standard.
  2. It is a 2.x slot. The Evga xc3 3090 is only a 2.2 slot though, so that will fit in a lot of cases. 0 points 4 months ago.

2 Slot Rtx 3090

Kosin a Chinese subsidiary of Lenovo has recently published a video showing how they modded their Ryzen notebook to run an RTX 3090 from the NVMe M.2 slot. Kosin used their Xiaoxin Air 14 laptop with a Ryzen 5 4600U processor for the demonstration. The systems internal M.2 NVMe SSD was removed and an M.2 to PCIe expansion cable was attached allowing them to connect the RTX 3090. Finally, the laptop housing was modified to allow the PCIe cable to exit the chassis and a desktop power supply was attached to the RTX 3090 for power.
The system booted and correctly detected and utilized the attached RTX 3090. The system performed admirably scoring 14,008 points in 3DMark TimeSpy, for comparison the RTX 3090 paired with a desktop Ryzen 5 3600 scores 15,552, and when paired with a Ryzen 7 5800X scores 17,935. While this is an extreme example pairing an RTX 3090 with a mid-range mobile processor it goes to show the amount of performance achievable over the NVMe M.2 connector. The x4 PCIe 3.0 link of the laptop's M.2 slot could handle a maximum of 4 GB/s, while the x16 PCIe 3.0 slot on previous generation processors offered 16 GB/s, and the new x16 PCIe 4.0 connector doubles that providing 32 GB/s of available bandwidth.

46 Commentson Kosin Demonstrates RTX 3090 Running Via Ryzen Laptop's M.2 Slot

If you wanted to connect your laptop to a desktop GPU, generally, you have to use a Thunderbolt 3-based graphics dock of some kind. However, a mod from Kosin (a China offshoot of Lenovo) has demonstrated that there is another way. Kosin shared a video where one of its employees managed to run an RTX 3090 off a notebook’s NVMe M.2 slot, and it works! (via PC Watch.)

Kosin used one of its own laptops, the Ryzen 4600U-powered Air 14, to demonstrate its modification. The modder first removed the M.2 NVMe SSD residing in the notebook, then connected an M.2 to a PCIe adapter cable, allowing the RTX 3090 to communicate with the laptop. Finally, the modder drilled out a slot in the laptop’s housing so the cable could run outside of the laptop’s chassis.

Surprisingly, performance from the RTX 3090 was perfectly adequate, even with just four PCIe lanes being fed to the card. The system scored 14,008 points in 3DMark TimeSpy: For reference, a standard RTX 3080 paired with a Core i9-9900K gets 15,000 points. So, yes, you lose quite a bit of performance compared to installing the 3090 in a desktop PC, but the score is still quite good considering the notebook’s specs (and the downgrade to four PCIe lanes).

If you want to do this yourself, beware that this is a mod and isn’t guaranteed to work. However, NVMe based M.2 slots run off pure PCI Express, so theoretically, you can execute this mod with little to no compatibility issues.
