AMD Launches Ryzen PRO CPUs: Enhanced Security, Longer Warranty, Better Quality (anandtech.com) 50
Reader harrisonweber shares a report: This morning AMD introduced their Ryzen PRO processors for business and commercial desktop PCs. The new lineup of CPUs includes the Ryzen 3 PRO, Ryzen 5 PRO and Ryzen 7 PRO families with four, six, or eight cores running at various frequencies. A superset to the standard Ryzen chips, the PRO chips have the same feature set as other Ryzen devices, but also offer enhanced security, 24 months availability, a longer warranty and promise to feature better chip quality. The AMD Ryzen PRO lineup of processors consists of six SKUs that belong to the Ryzen 7, Ryzen 5 and Ryzen 3 families targeting different market segments and offering different levels of performance. As one would expect, the Ryzen 7 PRO models are aimed at workstation applications and thus have all eight cores with simultaneous multithreading enabled, the Ryzen 5 PROmodels are designed for advanced mainstream desktops and therefore have four or six cores with SMT, whereas the Ryzen 3 PRO models are aimed at office workloads that work well on quad-core CPUs without SMT. The specifications of the Ryzen 7 PRO and the Ryzen 5 PRO resemble those of regular Ryzen processors. Meanwhile, the Ryzen 3 PRO are the first chips from the Ryzen 3 lineup and thus give us a general idea what to expect from such products: four cores without SMT operating at 3.1-3.5 GHz base frequency along with 2+8 MB of cache.

They fixed a few silicon errors in the spying functionality of the original chips that a microcode couldn't fix. So now that TLA can effectively spy on you, the processors offer advanced (national/homeland) security.

I read through. Its a handful of options such some processor space specific for biometrics recognition so the software isn't involved. Also there it chunck out the memory into slices. If a check bit is not set right on the slice its assumes something wrote directly to memory and throws and error to the OS.
I agree, hardware security is only as good as the software that is using it. It also takes away processing power from my core operations: Emulating the NES version of the Legend of Zelda at 240 frames

This time it does: it encrypts the main memory. So in the DRAM only encrypted data is stored. It gets decrypted on the fly, transparently when loaded into the CPU, so there is no special support needed by the OS or any software. This does increase latency of course.
This encryption can also be used to encrypt VMs running on the CPU, where every VM has a different randomly created AES key, isolating VMs from each other.

But what is the point of this encryption when the keys are still in disk and in memory somewhere, or how does the server boot up without admin? Does it go to eleven?

Epyc is the Xeon equivalent. The main differences between those and desktop CPUs are number of PCIe lanes and advanced CPU features.
These are something new... And then there is Threadripper too. These are like a cheap Xeon but for desktop motherboards, so you get some server/workstation features like the memory encryption but with cheap mobos and fewer PCIe lanes.

AMD took forever to get Ryzen out, but they really did do a good job with the chips. No games, no tricks, and 50% more instructions per clock. And to specifically answer your question: yes, each core has its own FPU.

Whoops, sorry for the mistake. I thought Threadripper was just a code name and Ryzen Pro was the release name. But it was a dumb mistake... the table shows "Ryzen 3 Pro" with only 4 cores and no Threadripper will have that few.

How could you not have heard? Ryzen is good enough that Intel is having a panic attack of sorts. AMD closed the IPC gap significantly, though Ryzen starts at a lower clock speed than the iX series and there's latency in cross CCX communication, but has increased core counts across the board. (Basically, it slightly underperforms in gaming-type tasks, performs well in multi-core tasks.)
From what I understand, the normal desktop Ryzen didn't worry Intel so much, but when AMD announced Threadripper (16-core

It's equivalent to an 8 core 16 threaded i7 4790k if one ever existed in gaming and beats the i7 7700k in productivity tasks and matches $2000 i7 6900 series CPUs in both gaming and productivity.

That's not what "superset" means... it means quite the opposite, in fact. If Ryzen PRO chips are a superset of Ryzen chips, then all Ryzen chips are Ryzen PRO chips, but not all Ryzen PRO are necessarily Ryzen chips. The intended meaning is the other way around, isn't it? All Ryzen PRO chips are Ryzen chips, but not all Ryzen chips are Ryzen PRO chips, therefore Ryzen chips are a superset of Ryzen PRO chips, or Ryzen PRO chips are a subset of Ryzen chips.
