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…

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.

Now imagine a Threadripper with the Zen2 cores, higher IPC and frequency would be certainly welcome. Have the 32 core 2990WX and it's an incredible CPU for compiling large C++ programs, running big test suites and never having to worry about running too many tasks at the same time.

A lot of AAA game studios with larger C++ codebases use Incredibuild a lot. I can imagine having something with this level of parallelism would be incredibly useful.

Icecream is the distributed compiler to use on Linux. Add ccache as needed.

Yup. Just waiting on the benchmarks from independent reviewers and to see how XFR in this generation works but I’ll be getting a Ryzen 9 if everything checks out. 24 threads will be amazing for local development (microk8s, and others) when I’m not gaming and save me from having to build a separate box.

Do you work on a desktop machine? At home?

Whenever I'm having a remote day yes. Some projects can take literally hours to fully recompile. The more cores, the better.

Will also be getting a Ryzen if the singlecore benchmarks show it's reasonable. Bunch of games I play at home tend to absolutely trash single core perf.

Earlier quoted context omitted.

They already launched a new generation of that recently, based on Zen+ with Vega. The previous one was pre-zen+. Their gpu+cpu chips are always based on the more mature tech.

The only Zen+ based APUs are mobile/embedded-only though. Desktop APUs are all still pre-Zen+.

The 2200/2400G is Zen-based.

My question is how is their architecture doing regarding the assorted speculative execution baked-in issues and what kind of impact is there on the AMD processors compared to comparable Intel CPUs?

Frightening lack of press around this. Basically all of Intel's and AMD's lineups are centered around high thread count right now. Completely useless if I can't reasonably enable SMT.

Read that often here tonight. Is there a killer app for single core performance other than UI/UX?

Literally everything other than the rare, very specific workloads that are amenable to parallel processing! (This isn't hyperbole.)

There's nothing "rare" and "very specific" about parallel processing, what's "rare, very specific" is the amount of software that's been rewritten/redesigned to take advantage of it so far. Sure, there are inherently-serial workloads, but most of what we use our machines for isn't like that. Parallel processing is not just about performance either but also general stability, a many-core processor can run a lot cooler and be a lot less fiddly than a high-end CPU core that packs the same amount of compute performance in a single CPU thread!

Takes guts to stick with that core count and at least you get to enjoy the full 70MB of cache. Good thing Blender and Cinebench all fits inside that, not sure you can ever say the same for productivity workloads. I guess AM4 also means no real improvements on the PCIe lane count: Would love to see real and IF switches to give a bit of flexibility and what they plan for a new Threadripper.

> I guess AM4 also means no real improvements on the PCIe lane count

The new Ryzen 3000 CPUs support PCIe Gen4.. so while the number of lanes will remain the same, their bandwidth could be doubled. Just announced Navi GPUs also support Gen4.

What will you be doing that will actually use 24 threads?

Run electron apps.
