The Raspberry Pi Compute Module 4 Review
Переглядів 363,618
День томуI put the Compute Module 4 through its paces, and compare it to the Raspberry Pi 4 and Compute Module 3+, highlighting some great new features like a PCI Express 1x slot on the IO board and NVMe support.
For even more detail, check out the blog post that goes along with this video:

Couldn't a custom cluster IO board be designed in a way that lets you mount the CM4s at a 90 degree angle? perhaps by using a sort of riser cable for the outermost connector.

@@Peter_Gamerrr You would need the riser anyways as the PCIE sot is expected to supply power, where risers can be powered with a molex/sata power cable for that power. GPU's don't only pull power through the 6/8 pin power cables as the PCIE slot is normally rated at 75 watts.

Hi, regarding the graphics cards, you can plug in a graphics card designed for "longer" PCI Express slots into a PCIe 1x slot. I did that a while ago with an external GPU solution. The card will not use it's full potential, but that affected mainly loading times, like texture loading. Basically anytime the GPU requests data from the rest of the system. Regarding drivers, have a look at AMD cards, they are open source and are included in mesa and should work.
@syndaquil4838 3 роки тому
You're right, but in this case it doesn't look like the PCI-e slot was manufactured with the back open to support that. He could open it up with a rotary tool, but it isn't something most people would be willing to do.
@CarlosGomez-vt9pk 3 роки тому
What I like about this is that you can take a mini ATX case, drill some mounting holes, and fit the IO board in. In fact, I wouldn't be surprised if someone makes an adapter to mount the IO board in place of an Intel board.

Just FYI, you may be able to get an PCIe x4, x8 or x16 card to work in an x1 slot using an adapter. This will of course only achieve x1 speeds but the other lanes will just remain unused, if following the PCIe spec properly. Some PCIe x1 slots even have "open back ends" to accommodate cards with more lanes. And some modders create the open back of the slot manually using a saw, file or similar :)

I haven't watched the video yet, but I'm pretty sure the Pi can't handle PCIe GPUs. I've had a look into this topic a while ago for the RK3399. Basically those small CPUs lack some sort of cache/memory that would allow them to operate a dedicated GPU. More precisely: This cache is too small.

You can use a 3080 in a 1x slot but expect around 1/16th the speed if the cpu can keep up. First you will need to cut the stopper at the end so the rest of the pcie slot can go through. But also good luck powering it unless you have a spare power supply and a way to jump the connection on boot. This also will apply to any pcie device like a 1x card in a 16x port or 4x card into a 1x port you just loose the bandwidth witch will slow down the device you plug in

Most PCI-e devices that have a bigger than 1x connector still work in a 1x slot because of how PCI-e works. Sometimes the smaller slots even have the end cut off so they also fit the longer connectors, but this dev board doesn't seem to have that. I also wonder how they deal with the 75W power delivery requirement through the PCI-e connector on such a small device. Wouldn't AMD GPUs have ARM drivers because they are open source, so could be compiled for any platform?
