I 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:

@LucasHartmann 3 года назад

The change in form factor was very well justified with a bunch of new features. Being parallel to the IO board will make your cluster wider, though.

@joelg1318 3 года назад

So true the dimm is expensive when designing a board.

@AndrewPerry1 3 года назад

Yeah, I didn’t get what he meant at the end when saying it takes up less space, it seems it will take up more at least in the horizontal plane.

@stale2665 3 года назад

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.

@LucasHartmann 3 года назад

I believe you would be better off simply populating both sides of the mainboard with CM4. Cooling would be easy too.

@stale2665 3 года назад

I was having that in mind too.

@charles2000wang 3 года назад

Use a modern AMD GPU card with a 1x to 16x pcie riser often used for mining. You should then be able to get a modern gpu running on the raspberry pi 4 CM.

@BrunodeSouzaLino 3 года назад

That works with almost any GPU. PCIe is backwards and downwards compatible and latency tolerant.

@charles2000wang 3 года назад

@@BrunodeSouzaLinoI specifically said AMD GPU because of the opensource drivers in the Linux kernel which should work on ARM ISA not just x86.

@Peter_Gamerrr 3 года назад

or just open up the back of the 1x slot with a hacksaw also works

@red13emerald 3 года назад

@@Peter_Gamerrr I mean a hacksaw is pretty extreme but some flush-trim snips would do the job. I’d be concerned about stability, though. Using a mining riser allows to lay down the GPU so it can’t damage the breakout board.

@kdb424 3 года назад

@@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.

@ElectricEvan 3 года назад

As a person who will be buying one of these for integration in an actual device it's way more important to have every i/o possible than for the board to be smaller.

@maurofoti526 3 года назад

Indeed that's a development board intended to better develop the more integrated solution the compute module is meant to be used in. Kinda weird that there's no usb3 though

@ChristOfSteel 3 года назад

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 года назад

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.

@cinobro6393 3 года назад

@BullCheatFR 3 года назад

6:50 that’s your issue! Modprobe is only temporary

@bartz0rt928 3 года назад

I think it's also worth mentioning that the new IO board is about 1/3 the price of the old one while having pretty much the same features, and that most of the power regulation is moved to the CM so rolling your own interface board should be a lot easier now.

@anders_nilsson 3 года назад

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 :)

@paulmaydaynight9925 3 года назад

i wonder if the existing Broadcom's 2.5GBASE-T and 5GBASE-T transceivers are pin compatible, and if so can you simply swap out that slower onboard Broadcom's 1GBASE-T and have it just work at 2.5GBASE-T speeds with the fully optimised pi4 openmediavault5 i dont know what ip blocks are included in this version of the cm chip revision, but is the onboard Broadcom connected to a totally separate internal pci lane too ?

@TmanaokLine 3 года назад

So hyped for that compute board!

@CarlosGomez-vt9pk 3 года назад

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.

@OsX86H3AvY 3 года назад

you said cant be used to boot....i recall on the RPi3 there was an OS that you would put onto the SD card which allowed you install OSes to an external USB device and then boot those OSes (after iitially booting to the SD card and selecting which OS to use) sorta like the OS on the SD card was like another bios layer if you will or like a pre-OS.....can you do that with NVME and still put the OSes on there that way?

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.

PCIe is not only backwards compatible, it's also latency tolerant, as demonstrated by the guys that hacked the PS4 by making use of the the PCIe bus connected to a serial port and it worked.

@johnathancrotzer5491 3 года назад

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
