My next CPU will be an AMD.

I bought a Ryzen 7 1700X and have been running Ubuntu on it for over a month now. It's insanely fast. (32 GB Ram, 1 TB Samsung EVO 970 nvme, Radeon 580)... I've even been able to overclock it some (3.4Ghz base speed -> 3.77 Ghz). Although I added some additional cooling and I think I could reasonably get 4Ghz out of it. I miss several of my core daily-driving Mac apps (Querious, MailMate, and Messages) but for ~$1,30…

I'm on a 1700 and I completely agree that it's fantastic. Around the time I bought it, Unreal Engine was released for Linux, so naturally I built that for Linux and the cores made it to a lot quicker.

Over the last 6 months or so, I've had lockup issues, and I thought I'd have to buy a new chip or RMA it, but it seems to have been fixed in a recent kernel as I haven't seen the problem in the last few months.

I'm looking around for decent AMD laptops and they're definitely making their way to the market. Lenovo's A and E series laptops look pretty good (though I've heard of throttling on the A series), and I'm waiting for more reviews on the new T series line. I need a laptop soon, but I may be able to wait until Zen 2 chips are available, depending on launch date.

AMD is making a strong comeback, and I'm excited to see what they release over the next few years and that Intel's response will be.

This was expected because the 3900X is optimized for fewer faster cores (12 at 3.8GHz) while the 9980XE is optimized for more slower cores (18 at 3.0GHz.) A better and far more impressive comparison would be the 3950X vs 9980XE which have comparable number of cores (16 vs 18). And in that instance AMD still beats Intel in both single-threaded and multi-threaded workloads! And by wide margins! And with AMD being 62% c…

You're forgetting Intel's trouncing in the Pentium4/Athlon XP days also. It's been a while, but I for one am looking forward to a very competitive marketplace for desktop CPUs.

I’ve used a laptop as a desktop for years but honestly I think having my laptop as a primary machine gave me /too much/ freedom.

Having a desktop makes me finish what I’m doing or makes me otherwise check out. I still take a laptop when I travel but now I’m just SSHing into my machine...

Out of curiosity, has anybody had anything in the AMD Ryzen instruction set missing that required you to purchase an Intel 9xxx instead? Any significant differences in regards to scientific applications or machine learning?

The mozilla/rr debugger doesn't work on Ryzen CPUs - https://github.com/mozilla/rr/issues/2034 (rr stands for Record and Replay Framework, it's a gdb extension which allows for reverse execution)

Interesting that GDB had its own "time travel" support for longer that afaik works on AMD. Will have to see what rr brings to the table.

Yes official and guaranteed support for ECC but it was an i3-8100 instead of an AMD equivalent. For a FreeNAS build. I will upgrade it to a Xeon E-21XX or whatever supports my Supermicro C246 motherboard in the future. AMD doesn’t test ECC on Ryzen but doesn’t turn it off. Server grade components are not as common either. Threadrippers are tempting but I like to play with EXSI and Intel’s virtualization is handy. My…

What precludes you from using ESXi and virtualization on AMD's platform? The virtualization extensions to x86 are common to both AMD and Intel. Even direct IO and IOMMU. Is there something missing?

The virtualization extensions are actually different, but yeah, VMware supports both across all platforms. I think it's only AMD Hackintosh where you might have an issue?

Why would they break if macOS itself runs fine on AMD? These softwares run on macOS and don't make any system calls directly by bypassing the OS, right?

They typically check for a network interface from a real Mac. Using a Hackintosh you can't spoof some of the NIC details that are detected and cause iCloud/iMessage to not work.

Oh, wasn't aware of that. So does iCloud / iMessage work when macOS is run virtualised?

There are many reports about problems with 1700s running Linux

Mine (bought a bit more than a year ago) got one random SEGV in maybe 5,000,000 processes when all threads are busy. That's a lot if you are doing full Yocto builds starting 3,000,000 processes each. And maybe one lock-up per month even without heavy load. Not sure whether there is only 1 problem or several of them. A year of kernel updates and one AGESA update promising to fix random freeze has never made any change. I returned my CPU for replacement this week, not sure whether I'll get a new one.

Supposedly a new 7nm fab in Taiwan is going to cost around 17 billion dollars just for the FAB. Not sure Apple share holders will think trying to compete with intel and AMD is good use of their money

$17 billion is peanuts for Apple. However, Apple uses TSMC for fabrication and they are already at 7nm. No need to own fabs. AMD doesn't own fabs either. The Apple designed A12X Bionic processor contains 10 billion transistors and is already competitive with desktop processors from AMD and Intel. Do you think it would be that difficult for Apple to design a desktop or laptop version? They have more than enough money…

But it is the share holders peanuts - is a quixotic and expensive charge to over take AMD or Intel the best use of our money?

True, Intel's part numbering scheme has passed beyond all reason. Think about the i9-9900K/KF. Existing SKU, in stock at Newegg for $479. You don't get quite as many cores but you get a lower price and higher single-core performance, and it exists right now instead of being unobtainable hypeware.

like I said, I'm very interested to see the head-to-heads, especially the overclocking results. my use case is c++ compilation and csgo so it looks like it'll be a tough choice.

Seems like for C++ builds you are always going to want the most cores for the money, even if the single core performance is a little worse.

You're probably right. But don't underestimate Apple. They have $250 billion in cash reserves.
