how does that 5700U compare to the 4800U? The specs look strangely familiar (if that cache value of 12MB is both L2 and L3 added together). Is this just a rebadged chip?

The clocks are slightly tweaked, but I think you are right.

To both the above they say in the article they are the same as the non pro models the only difference is the enterprise features…

The Pro models map perfectly with their non-Pro counterparts. There is no Pro 5750U, however.

The standard 5700U is also odd insofar it is based on the Zen 2 Lucienne implementation, rather than Zen 3 Cezanne.

The standard 5700U, 5500U, 5300U are all based on the Zen 2 implementation, rather than Zen 3 Cezanne.

IIRC they all (zen2 and zen3 alike) share the same graphics. So the big difference is the zen 3 performance boost from what I can tell however the ones on zen 2 won't benefit from any such improvements that zen3 brings, so those 3 models are essentially 4000 series with marginally better clocks (the old 4800U and 4600U), and in the case of 5300U hyperthreading has been enabled too which is an improvement on the old 4c/4t 4300U.

No mention of ECC memory here? The 3000 and 4000 series Pro chips all had ECC support. That would be at least as important as all the memory encryption they talk about for things like repelling Rowhammer attacks. Would have expected more noise about AMD supporting ECC after Linus Torvalds' rantings at Intel a short while back.

I'm pretty sure AMD does support it but it's down to the mobo maker etc. It's been like that for years on lower end cpus
All my Ryzen setups support it, but I don't run it at moment as they don't need ecc. Probably in fairness to ecc ddr4 being vastly more when I looked than regular

The stuff is a bit more expensive (9 chips to buy instead of 8, but mostly lower sales volumes), but then these pro chips are not intended for home users.

Yeah got ecc on the stuff that requires it and is still ddr3 (server/nas) which is a great help. The nas runs zfs for redundancy and ecc is pretty much essential to ensure no data loss. My rtmp server has just been upgraded to ecc as well
