The signaling requirements are way too tight for pluggable VRAM to ever be a thing. If anything we're headed in the other direction, with CPUs losing pluggable memory in order to achieve tighter timings like GPUs do, Apple is already doing it and Intel is set to follow.
Exactly. There's a reason these chips are always surrounding the processor (since the 2000s) and why we haven't seen GDDR based plugable memory modules.
For this same reason (timing precision) you see that soldered DDR5 memory often reaches way higher speeds than what's available in DIMM or SODIMM form.
We're already half-way in a heterogeneous future, with chiplets[1] and mixed cores[2][3] etc. Could we expand this to memory, having some soldered (on-chip?) high-speed memory, and then slots for additional slower, yet faster then the alternatives, DIMMs?
Or would the cost of the extra complexity of the memory controller likely not be worth it ever?

Intel's already doing that with Xeon Max, it has both onboard HBM and an outboard DDR5 interface. It can be configured to run entirely from HBM with no DDR5 installed at all, or use the HBM as a huge cache in front of the DDR5, or to map the HBM and DDR5 into different memory regions to let software decide how to use each. I don't think there's been any indication of that approach filtering down to consumer architectures though, Intel is talking about doing RAM-on-package there but without any outboard memory interface alongside it.
Obviously high-end consumer CPUs already have about 30MB of on-chip memory, with server CPUs reaching a solid 300MB. We just prefer to call it L2 and L3 cache. If we add more memory in a chiplet format I suspect mainstream CPUs would simply expose (or rather hide) it as L3 or L4 cache.
Most software isn't even NUMA aware, and would completely fail to take advantage of a tiered memory hierarchy if it was given the option. But if we make the fast memory a big cache and let the CPU worry about it it's a "cheap" win.
Though there is the Xeon Phi which has about 16GB of on-package memory that can either be configured as cache or as "scratchpad" memory. But of course that's not meant for general-purpose software
I'm looking forward to the performance, but not looking forward to higher capacity RAM being segmented off to overpriced "professional" SKUs like high VRAM capacity is on GPUs. Currently you can run up to 192GB RAM on a consumer CPU platform but I doubt RAM-on-package consumer parts will scale that high.
Yeah manufacturers love this evolution because it means everyone who wants or needs high memory will be forced to buy for their projected memory needs throughout the live cycle of the product on day one, and the only place they can get it is at inflated prices from the vendor.
I wonder how they will do this in the workstation and server space, I don't really see how they can do away with socketed CPUs.
I wonder if we will go back to slotted CPUs, with a SOM style board with CPU and memory being plugged into a motherboard/chassis that's really just an I/O back plane. How will multi Cpu communication look then?
I guess we already have memory being pinned to a NUMA node and connecting to others via a vendor specific interconnect, so maybe it's not that strange and different from today.

I'm guessing the endgame will be consumer parts all being RAM-on-package with no external memory interface, and workstation/server parts will take a hybrid approach like Intel is already doing with the Xeon Max chips which have 64GB HBM on the package and an external DDR5 interface supporting terabytes of slower bulk memory.
I haven't upgraded this CPU yet, as it's still too new, but my last motherboard got two new CPUs, and previous was 2-3? (Maybe more it was awhile ago, thanks AMD)
Given that AMD has been releasing AM4 CPUs since 2016, I think it's reasonable to assume that many of those who know how to build computers in the first place have upgraded their CPU. Why switch the whole motherboard/CPU combination when you can just plug in a better CPU?
Well, if you've been using Intel platforms you do because Intel obsoletes the chipsets at a rapid pace so there often isn't anything appreciably better to upgrade to on the platform.
One could imagine a two deck PCB, where you have another PCB board underneath the main one for additional close memory chip locations with a high density vertical interconnect.
EU companies selling in the US have to follow US regulations, US companies selling in the EU have to follow EU regulations. And in both cases, only for activities in the respective market.
For example Apple would be free to sell lightning port iPhones in the US and USB-C iPhones in the EU. Or don't make USB-C iPhones and not sell any iPhones in the EU, if they don't want to be "leeched". Same for Nvidia and this hypothetical regulation for swappable RAM (which is never going to happen because it isn't technically viable)
If you do business with citizens of another country, in that country, you should expect to have to follow that country's regulations.
Your position is literally American exceptionalism. Do you think that because of NATO that US companies should be able to ignore EU consumer protection laws?
exactly, in the court rooms you have scientists on each side of the case. They've all graduated from the same Ivy Leagues, just are getting paid by different teams.
when people slack at their jobs and just let other team members pick it up... it seems so scummy. Someone has to have a 'challenging' upbringing to have this be their default mode of operation.
I think thats definitely a signal that the B and C teams werent needed, considering they cut 90% of staff LOL.
As for the bots, AI is making it easier than ever to bypass those systems. CogVLM is just sitting there menacingly on github https://github.com/THUDM/CogVLM
>> I would love to hear why old ppl don't choose to voluntarily end their life. What good is a life spent in 'poor house for the old' .
The old age is considered prime meditation time in the shaolin monasteries.
Even if you live in poor conditions, exploring the realms of your subconcious in meditation is seen as an end goal. See Jhana stages to achieve in meditation.
We should as a society encourage and normalize assisted suicide in old age when they aren't happy anymore. Why suffer everyday with no chance of it ever getting better just do some mediation nonsense.
