Conan Kudo: how is your Linux experience on MacBook so far?
<thefossguy>
You eyeing one?
<davidlt[m]>
Oh yes. I worked on AArch64 back at CERN, and I have been dreaming about this for a long time.
<davidlt[m]>
It would replace my PineBook Pro :) Which is basically a fun toy.
<davidlt[m]>
As soon as there is a proper riscv64 laptop I will get that too.
<thefossguy>
Everything aside, repairability (not upgradability) is my main issue with Apple products.
<thefossguy>
Changing my NVMe at the very least
<davidlt[m]>
I have replaced multiple parts on my laptop, but I cannot replace a broken plastic part that holds lid hinge.
<davidlt[m]>
Memory and NVMe (and potentially WiFi card) would be nice to have replaceable.
<davidlt[m]>
But in general. I don't expect memory to be replacable long-term.
<davidlt[m]>
It's gonna go more towards what Apple did. On a substrate, multiple channels, wide bus, smallest distance possible to lower the latency and get better signal integrity for those high speeds.
<davidlt[m]>
There could be two tiers of memory. That existed already in some HPC products.
<davidlt[m]>
Intel ADM also sounds cool. Sounds there could be a few GBs on L4 (or eDRAM like?) directly under the compute die.
<davidlt[m]>
AMD announced something similar. Basically their 3D V-Cache will move below compute die.
<davidlt[m]>
Recent rumours about AMD mega APU (finally) also suggest they will go similar route.
<davidlt[m]>
Also DDR5 SODIMMs are already limited.
<davidlt[m]>
You will not be able to get higher speeds on those.
<davidlt[m]>
That's why Dell is pushing their new form factor to JEDEC IIRC.
<davidlt[m]>
I just cannot believe we needed Apple to do something that already existed (and in rare cases was available in HPC).
