Surprised no one(?) commented on the case yet - looks like they came to their senses and went back to the "old" case design. I've been seriously considering a second-hand, early Mac pro - just for the case. Not sure if they fit regular/modern psus - but those cases were very nice. Good riddance to the trash can design... Now, if these wouldn't be priced like a car, and came with some proper AMD cpus ...

Yes. I work on a Linux distro, and the amount of time my 1st gen 32 core Threadripper has saved me is truly mind blowing. It made it possible to do changes I wouldn't have dreamed of. As an example, I worked a bunch on our PostgreSQL infrastructure, but we support 5 years of versions. So you have to CI/integrate your changes and test them across all 5 versions, every time you test. My machine could do this on the ord…
How's kernel support and VM support such as QEMU lately? I'm thinking to buy i7 for embedded OS dev but that sounds very tempting. I heard AMD CPUs had some breaking issues last year.
It happened, when the 2nd gen TR arrived. It used the same mainboards, so all the manufacturers issued BIOS updates.
Unfortunately, these updates claimed to support SEV (Secure Encrypted Virtualization). Linux of course tried to initialize it at boot/module load time and the entire thing went hanging, because TR CPUs do not support SEV, only EPYCs do.
So there were the following fixes:
1) downgrade BIOS back to pre-TR2 version,
2) blacklist the ccp module; which would make kvm_amd non-functional,
3) wait for a fix in Linux kernel, which initializes SEV with a timeout.
So it wasn't that tragic issue, if you had first gen TR.
So apart from the pleasure of being able to use MacOS, I presume it will be cheaper to just put these parts together myself, yes? If the form factor is just a tower, well I can buy a tower myself. What is the advantage of paying for Apple a (presumed) bunch of money to build it for you? If you don't want the hassle of building a PC (which is fair) there are an endless supply of places that will put PCs together for y…
Actually those server boards and CPU's from Intel are pretty darn expensive, as well as the fancy RAM etc. For it's specs, I think technically it is an OK price, but obviously for almost all other purposes you can custom build a PC for a fraction of the price yes, that's still really powerful. If you know how to hackintosh you can run Mac OS too. But yeah it's to get Mac OS, that's how it's always worked, and the App…

I got a Lenovo laptop with roughly the same specs, though.
Your Lenovo laptop has an 8 core 3.2GHz Xeon with 4.2GHz Turbo Boost, 19MB Cache, 64GB DDR4, silent cooling even under heavy load (which it can sustain), and an SSD that does 1700MB/s with full disk encryption?
Even those crippled by being connected to two lanes can achieve this speed.

I've always argued that for the prices that Apple charges Apple Care should be included in all its products. The first Apple computers I bought lasted for years and I never thought Apple Care was necessary, but since the fiasco with the 2011 MBP and the butterfly keyboards I'm not buying another of its products without Apple Care. Yes, Apple ended up doing the right thing in both cases but it took years after the pro…
I don't think Apple should necessarily include coverage for user-caused damage as standard, but having only a single-year warranty on manufacturer defects is kinda shameful for a premium product. I expect premium products across most product categories to carry a three or five year warranty as standard. A single-year warranty is in general an indicator that a) the manufacturer doesn't have faith in reliability past t…
Dell's Precision workstations come with 3 years warranty, upgradable to 5 years coverage with on-site service. There is no reason Apple can't match that.

Nvidia is still better for games then AMD. Haven't seen the GPU which beats them.
Isn’t that only if you ignore price? If you only have a limited budget, then AMD will get you better performance. For absolute maximum performance at any cost AMD has nothing that can beat Nvidia though.
Why do the different processor quantities have different base frequencies (higher for lower CPU count) but the same "Turbo Boost" frequency of 4.4 GHz? If you ran Folding@Home on one of these, would you get sustained 4.4GHz clock speeds?
Furthermore, I think the advertised Turbo Boost 3.0 frequency is single-core only. It will not increase all core frequencies to that level unless there is sufficient thermal headroom.

Both necessary and well worth it, as Apple simply wasn’t selling anything appropriately powerful for like five years (also why x99 was so tricky until more recently - no equivalent hardware of theirs), but by any other calculation if you actually put the value of your own time anywhere close to any professional scale (or see it as a hobby) it will very likely end up costing way more to do yourself.
