I'm really looking forward to this. But one issue with current AMD cpu is that you have to buy a desktop GPU even when you are not doing any kind of gaming and such. I know intel iGPU haven't been terribly good but for work they are good enough and is one less part and cheaper to boot. For same performance a Ryzen 3rd gen + gpu might still be cheaper but the price advantage gets reduced. I haven't really seen that me…

2200G and 2400G from current gen ryzen have integrated graphics though.

You could pick a Ryzen with "G", like the Ryzen 5 2400G, though... They have an integrated GPU.

Unfortunately there were no desktop G parts (APUs) on the Zen+ architecture (as far as I know.) And they're not in the first round of Zen 2 either. The 2400G, which I think is currently the top desktop APU, launched in Feb. 2018 and has four cores.

2xxx series is zen+, also ops complaint was about current gen ryzen, which the 2200G and 2400G fall in to.

Run electron apps.

I know this is a joke but aren't Electron apps single threaded by nature and usually memory hogs? So more memory would be better and having many cores is good too.

Electron apps have Helper processes. e.g. I currently have 3 Microsoft Teams Helper processes (with 37, 36, and 16 threads) running and 3 Spotify Helper processes (with 16, 9, and 4 threads).

make -j24

Be sure to have enough RAM, so you will not run out of it. (For some reason, when building projects like LLVM with -j 16, 32 GB w/o swap may be not enough. With -j 2, it is enough, but takes an eternity).

Yes, building Ceph with less than 24 GB ram on a 16 core machine will make it run into Out Of Memory situations here, so that the OOM-Killer is summoned and kills the build..

No 5GHz, I'm disappointed. Was considering switching to AMD, but Intel looks better. I'll wait for Threadripper announce, though, may be they'll release something powerful.

This may be an oversimplification. There is more to it than just megahertz or gigahertz. The most important metric in this case is work done per clock, on average.

It's like 10 years ago when all hardware shops were advertising the size of their PCs harddrives as if that made them faster.

Implying that there's a computer in existence that runs those fast.

Awesome, I just realised that the old "run Crysis" joke has been replaced.

Electron apps do manage to make a mockery of my PC's specs though.

NH-U12A. And yeah, it's fairly expensive for an air cooler.

Thanks! Been a couple years since I built a new PC, and it's helpful to have that info for anything I might build soonish.

If you don't know about it, pcpartpicker.com is a fantastic resource for building a new system.

It makes researching and comparing a bunch of brands and parts as well as waiting for the best times to buy a breeze.

Unfortunately the market with low power AMD cards is non-existent. Maybe some older HD model if you can find it second-hand, but those can't do 4K@60Hz. There is no low powered (=passive cooling) card based on the recent AMD chips. I wanted GPU with only passive cooling for my Xeon machine, had to buy lowend NVIDIA. Hopefully Navi at the end of the year will finally change this.

What are you talking about? you can get RX550s that are passive or even one of the rare RX560s which are passively cooled

I can't find a single passively cooled RX550, albeit some are passive up to a certain temperature, which is likely acceptable for the usecase assuming it works as advertised.

Could be that it'll still continue to have stability issues. For some reason Ryzens are extremely picky when it comes to memory. There's really no guarantee that 3-rd gen will resolve this issue. It's to the point where e.g. Corsair makes memory specifically designed to work with AMD CPUs. This memory typically contains Samsung B-die chips which work fairly well.

No, the stability issues they're talking about are on a release day 1800X. It's not memory issues, and I've never had memory issues with either of my Ryzen processors. This is the issue they're certainly talking about: https://www.phoronix.com/scan.php?page=news_item&px=Ryzen-Se... And it is assuredly not a problem with any Ryzen processors manufactured after the very first few months.

Well, there are some stability issues with my ryzen 2700x. At first there were CPU freezes in idle on Linux: https://bugzilla.kernel.org/show_bug.cgi?id=196683.

After applying workarounds, I still see some strange crashes, not sure if at least some of those are still related to the CPU hangs from the bug above. TBF this might not be the CPU's fault. This is all quite annoying to me and time intensive to investigate (where do I even start?). Even though I really like AMD's tech I am quite frustrated and I haven't had these problems with my previous Intel builds so far...

Those APUs are a weird mix between Zen and Zen+, they got improvements over Zen but they are not fully Zen+, and they even have some unique drawbacks (the TIM, they are not soldered).
