(found the topics for this guys, sorry for posting this, most of this was already answered time ago) I have one question now that I have the uconsole in my hands. I still do not have a CM4 lite and have a few options, but I wanted to know from the ones having this experience first hand that is most of you guys:
My question is, how much the trade between power/heat vs ram on the CM4 is worthwhile and how is this compared to the CM5?
Also, I wanted to get the SSD extension board, if so the CM4 lite can be used with this one? and now that I am looking into ordering a CM4 is there any useful difference between asking one without wifi or with wifi?
Warm regards guys!
P.S. Yes I am reading a lot of posts and docs right now! I am extremely interested in all your experiences
You’ll definitely want to have the wifi version and as far as im aware the consensus is to get a cm5 if you can afford it as the heat and power restraints are negligible or fixed by simple mods. Though I am not an expert I just have been reading these forums a bit so if someone smarter than me replies going against what I say believe them over me.
-yes I do need the wifi version of the CM4 or CM5 as the uconsole cannot connect to the CM4-CM5 pins for that.
-CM5 is faster but drains battery faster, you can cap the cpu clock to fix this.
-The bottleneck is not the cpu but the os access as if you use the SD to store the OS, you depende on the reading and writing speed to the SD, if you buy a expensive one they can go up to 300 mb/s or maybe higher but those ones are extremely expensive.
-Storage is a better option here but you need to board to flash the CM4-CM5 and then you do no ask for a lite version.
SSD is better option apparently.
Any upgrade makes the device to consume more battery so… time to check the energy storage stuff.
It break my heart that a CM$ with wifi is needed and there is no version of CM4 that can use to onboard wifi, but right be I can ask for the A06 module, after all… is cheaper than the CM4 nowadays. Do anyone has any idea how much this will take to be shipped?
On the cm5 emmc is indeed faster than the sd, on the cm4 the speed is limited by the interface and emmc and sd are about the same speed.
But you do lose the sd card slot, which is a big flexibility downgrade in my opinion, especially now that we can also get a third party nvme upgrade, even faster with the nvme, and your storage dying does not brick the processor.
Sd speed is also limited by the pi, so the fastest SD cards are a waste of money.
The A-06 has the same issue as the radxa, without the community supporting it you’re mostly on your own getting it to work with the new screen revisions and if you want up to date kernels you’re going to have to be willing to be the maintainer for that kernel.
So while it is still for sale, I wouldn’t recommend buying it at this point. Even if it has become a better deal with the big pi price increases
