Very cool, I’m probably thinking too much but why are they seemingly hyping this now (I’ve seen a bunch of this recently) with no M5 Max/Ultra machines in sight. Is it because their release is imminent (I have heard Q1 2026) or is it to try and stretch out demand for M4 Max / M3 Ultra. I plan to buy one (not four) but would feel like I’m buying something that’s going to be immediately out of date if I don’t wait for the M5.
I imagine that they want to give developers time to get their RDMA support stabilized, so third party software will be ready to take advantage of RDMA when the M5 Ultra lands.
I definitely would not be buying an M3 Ultra right now on my own dime.
I am typing this on my own 512GB M3 Ultra. I've just put out some feelers for 2nd-hand sale price...
I have an M4 Max I can use to bridge any gap...
Does it actually creates a unified memory pool? it looks more like an accelerated backend for a collective communications library like nccl, which is very much not unified memory.
The yearly release cadence annoys me to no end. There is literally zero reason to have a new CPU generation every year, it just devalues Mac hardware faster.
Which I guess is the point of this for Apple, but still.
