Holy moly this is awesome! I am in for the 128GB SKU.
That’s 96GB of usable VRAM! And way more CPU bandwidth than any desktop Zen chip.
I know people are going to complain about non upgradable memory, but you can just replace the board, and in this case it’s so worth it for the speed/power efficiency. This isn’t artificial crippling, it physically has to be soldered, at least until LPCAMM catches on.
My only ask would be a full X16 (or at least a physical X16/electrical x8) PCIe slot or breakout ribbon. X4 would be a bit of a bottleneck for some GPUs/workloads… Does Strix Halo even support that?
I understand the memory constraints but it does feel weird for framework, is all I have to say. But that’s also the general trajectory of computing from what it seems. I really want lpcamm to catch on!
Eventually most system RAM will have to be packaged anyway. Physics dictates that one pays a penalty going over pins and mobo traces, and it gets more severe with every advancement.
It’s possible that external RAM will eventually evolve into a “2nd tier” of system memory, for background processes, spillover, inactive programs/data, things like that.
DRAM is so cheap and ubiquitous that they will probably keep using that, barring any massive breakthroughs. The “persistence after power-off” is nice to have, but not strictly needed.
Apparently Framework did try to get AMD to use LPCAMM, but it just didn’t work from a signal integrity standpoint at the kind of speeds they need to run the memory at.
My AM5 system doesn’t post with 128GB of 5600 DDR5 at higher than 4400 at JEDEC timings and voltage. 2 DIMMs are fine. 4 DIMMs… rip. So I’d say the present of DIMMs is already a bit shaky. DIMMs are great for lots of cheap RAM. I paid a lot less than what I’d have to pay for the equivalent size of RAM in a Framework desktop.
It’s correct. A product with various options will have each combination of options under a different SKU. It’s a singular number that identifies an exact version of a product.
its used to mean a new product that you specifically have to keep track of. e. g if you found framework desktops in a store, it wouldnt all be sold under 1 sku. all 3 ram capacities would be 3 different bar codes

It’s already fourth tier after L1, L2, L3 caches.
Maybe something like optane will make a comeback. Having 16gb of soldered RAM and 500gb of relatively slow, but inexpensive optane RAM would be great.

Sounds like it doesn’t bode well for the future of DIMMs at all, TBH.
You have a DIMM view of the future.

What’s a SKU? Google just says “Stock Keeping Unit”, but I don’t think that’s correct in this context.
It’s correct. A product with various options will have each combination of options under a different SKU. It’s a singular number that identifies an exact version of a product.
In this context, SKU refers to a variant of this product. That is the correct acronym as I understand
its used to mean a new product that you specifically have to keep track of. e. g if you found framework desktops in a store, it wouldnt all be sold under 1 sku. all 3 ram capacities would be 3 different bar codes
not only new
As others said.
In this context it would be one of the CPU/Memory combinations framework offers: https://en.wikipedia.org/wiki/List_of_AMD_Ryzen_processors#Strix_Halo_(Zen_5/RDNA3.5/XDNA2_based)
