I'm looking at building a new system, and was waiting to see what happens with this chip and Intel's Arc Pro B70 card. I can't find ECC UDIMMs of 64GB per-stick to make 128GB, but I can put together two solo UDIMMs of 32GB or 48GB for $800 and $1000 per stick respectively.
I really want to see what enabling the L3 cache options in the BIOS do from a NUMA standpoint. I have some projects I want to work on where being able to even just simulate NUMA subdivisions would be highly useful.
The not so good side is that getting a RVA23 development board this year with an usable size of RAM (for e.g. compiling and linking large code bases) is not going to be cheap.
I hope this is still enough for the planned upgrade to Zen7 in 2028.
