What will you be doing that will actually use 24 threads?
Run electron apps.
Implying that there's a computer in existence that runs those fast.

I don't mind 12 cores / 24 threads on my desktop. Makes compiling Mesa, Wine and Linux kernel a lot faster.
Cool, but we haven't seen compiling benchmarks yet. 12 cores might be bottlenecked by dual-channel memory.
The AMD Threadripper 2990WX has 32 cores with quad-channel memory, and it seems to do fine.

16C is probably coming later once Intel responds.
Intel are planning a 10 core desktop part, so the moment it pops its head up AMD will drop their 16 core chip on it.
Yeah, that's almost a given isn't it? If AMD has really closed the single-thread performance gap then Intel is in for a hard few years in this market. Looking forward to independent benchmarks.

You can get a cheap passive gpu, most don't even need power from the PSU. Something like a nvidia GT 710 or 730.
Is there anything similar but from AMD? As a Linux user I'd rather not buy nVidia.
Something like the R5 230 or RX 460, several generations old, but will do.
Re: AMD Ryzen 3000 announced
#175I'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…
They use the same chip for desktop and for server market where it doesn't make much sense to add a crappy iGPU. Intel with their scale could build much more different chips.

Having 24 threads doesn't mean that -j24 is the sweet spot. I have a machine 56 thread Xenon machine for building git.git, and I find that with its sockets/threads-per-core/threads-per-socket of 2/2/14 the sweet spot is closer to sockets*threads-per-socket = -j28. Things speed up rather linearly up to -j28, but once I get past -j28 (say -j32) it levels off, and -j56 starts being counterproductive. Same thing with the…
And on architectures like EPYC you run into NUMA issues and having to pin things to certain cores, right?
make launches separate processes, so NUMA should not be an issue, there's no interprocess communication.

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.

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).
If you build LLVM often, use the shared library build (BUILD_SHARED_LIBS=true). Most of the memory usage (and a large part of the time in incremental builds) comes from linking final artifacts if you do not use shared libraries.
Thanks for the tip, unfortunately, when I'm building it (occasionally), the LLVM itself is part of another project (AMDVLK) and changes too.

That is probably true, but if I am buying a GPU for hundreds of dollars I don't care as much about the cost of the CPU. I think AMD needs to do something if they want to fulfill the potential of Ryzen. (Removing or minimizing the role of the chipset might be interesting for example).
Not necessarily. For instance if your target is 1080p gaming you can do that on a budget with an RX 570 or RX 580 + a reasonably priced Ryzen 7 chip. This market isn't at all competitive for Intel because it's price conscious and iGPUs aren't anywhere near up to to task. The only market that doesn't care about CPU price is the market that doesn't care about price at all. i.e people building systems with i9-9900K or X…
I am just not sure it is a super strong market. As far as I can tell those cards have been selling for roughly the same price or more as when they were introduced 2 years ago. A lot of people would just stick with what they got, or get a laptop instead. If the price of GPUs and memory was half of what it is it would make a lot more sense.
Re: AMD Ryzen 3000 announced
#180I’ve really been looking forward to these chips. The 2700X was pretty close to Intel in 1440p benchmarks, so I’m looking forward to what the likes of Gamers Nexus have to say about overall performance, specifically in line with performance elements like frame render time. Not that it really matters to me. I’ll have one of the 8 core chips on a micro-ATX X570 and build up a system around that. I’ve purposely held off building a new desktop because of Ryzen 3000. In a Ghost S1 or NCase M1, it should be the ideal CPU for a powerful SFF build.
