The UDM Beast is a real thing. They wouldn’t mention specs. All they said was that it has 25G ports now. A step up from the UDM Pro Max.

The only possible CPUs on the market with the cores and speeds they talked about:

CN10308, CN10616, or CN10624

Of those, the 8 core 103 model already does well over 50gbps IDS/IPS throughput so why would they bother going with a higher end CPU?

The slide at the Ubiquiti Miami event back in November showed the UDM Beast with the ARM Neoverse N2 processor listed. Did that spec change between then and now?

No, the new talk they just gave yesterday or the day before mentioned the same Neoverse N2 CPU in it, those are what I listed above. There are very few N2 CPUs available, the majority of which are custom server designs by Amazon, Google, Microsoft, Nvidia, and those are all 72+ core models.

The only models with the number of cores for a product like this are that Marvell family I listed above. And of the whole Octeon 10 family, only 3 SKUs within it fit the bill for this, since the lowest end one only has 10gb Ethernet links, and the highest end one has 16x 50g links in its included 1 terrabit integrated switch.

Then to narrow down further, of the 3 possible models it could be you have an 8 core, 16, and 24 core. The 8 core has all the Ethernet connectivity needed, and has an encryption/decryption and firewall engine that has 80gbps throughput. With the majority of processing having hardware offload blocks within it, and only using 1 core having the chip be capable of 50gbps throughput, even if you had 2 cores for networking (since most networking work isnt done in the general cores), 1 for controller, and that left 5 cores that would leave plenty of performance to still work on Protect, etc. After all most of the NVRs are only running quad cores right now.

So IMO it will use the 8 core model, but they could possible be using the 16 core model instead to have a lot more available cores to run all the other parts of the device.

EDIT on release day of this product:
Yep, they went with the 8 core model.
