For those wondering like I was after reading this comment, both the anandtech and phoronix test setups are patched for Spectre.

Phoronix now has Windows 10 vs Linux tests:

Sure enough, many of the benchmarks feature dramatically better performance on Linux. Michael also writes:
"The Windows 10 vs. Linux tests were done out of opportunity with having that Windows installation around without giving it too much thought, but on this 2990WX launch-day it's been surprising to see some of the performance results from some of the Windows publications. Had I known how poorly Windows 10 works on current high core count NUMA environments under some workloads, I would have certainly ran more benchmarks. But that will come in another article then as well as possibly looking at the Windows Server 2016 vs. Linux performance on the 2990WX to see if Windows behaves better there for this NUMA box. So treat this as the introductory article and more Windows vs. Linux benchmarks will be on the way as time allows."

#153Will there be motherboards to fit two of these chips like in my current dual 6-core Xeon? 64 cores / 128 thread in a single workstation would be insane, and fit in very nicely with my lab :)
No.

#154Honest q: What home-use workstation would use 32 cores? (Excluding home labs or servers).
It takes roughly 20-minutes to make a SINGLE good frame using Cycles on Blender. Cycles is a raytracer for 3d modeling. If you are making a 30-second animation at 24-frames-per-second, that would be 720 frames, or roughly 240 hours (10 days) of rendering. 30-seconds would be roughly the length of a standard commercial. If you have a computer that is 2x or 4x faster, that cuts the time down to 5 days or 2.5 days. Whic…
Or you buy good graphics card and you blow CPU out of the water. But it is true for render engines like Arnold or Corona CPU is main thing. For cycles get gpu.

Minecraft reigns king in that category. I don't know if it still does, but a couple years ago Minecraft actually managed to somehow still use the OpenGL immediate mode. Back then the larger Minecraft servers required ridiculous amounts of memory and dedicated a dozen cores just to Java's GC.
That's still pretty much the case today. Though the underlying java GL library the desktop client uses has been updated a bit and the newer versions have migrated to higher versions of OpenGL; breaking a lot of mods pretty hard with the changes to the rendering engine. I hear the (Windows/console only?) version is faster for all the reasons you'd expect, but I'll probably end up never playing it.
Windows version has way better performance, but it doesn't support mods so nobody cares about it.

FWIW, I believe the version they use relies on a version of MSVC where the linker is predominently single-threaded, and linking the final binary ends up as a significant proportion of the time.
Does anyone do multithreaded LTO yet?
GCC and clang do. As a matter of fact, MSVC does too, to some extent (CGTHREADS option, iirc).

Not my experience. I've had stutters with Ableton Live on a 4 core machine with 2 cores still idling around. Ableton cannot multi-thread a single track (at least in Version 9), and if you're using a single-threaded VST that does not matter anyway.
> Ableton cannot multi-thread a single track (at least in Version 9) This is still the case in 10, and one of the reasons I have been seriously looking at Bitwig (Linux support being the other).
Is situation in bitwig better?

#158Honest q: What home-use workstation would use 32 cores? (Excluding home labs or servers).
For compiling, having many cores is fantastic. Granted, on a workstation, compilation normally just involves a few files (the ones that have changed since the previous build and their dependencies), but when you have to do a full rebuild, it is fantastic to be able to do `make -j16` and watch it chug through 16 files simultaneously. Interestingly, the benchmark in this review shows that the 16-core 2950X compiles Chr…
this.
One of the projects I compile at work can take an hour running on 4 threads, jack that up to 16 and you take that down to not much over 17-18 minutes. That's a whole heap of developer time you just got back that would have been wasted on compiler swords.
The other one is running VM's/a docker swarm locally for development.

Does video editing or After Effects work could as home use yet? Video editing, in terms of cutting and splicing clips, is not going to benefit much from this chip, but a lot of effects rendering will benefit, and basic video editing uses a lot of effects these days. That’s all I’ve got.
Yes for roughly 8-threads or so. 16-thread Threadripper is mostly idle in my video-editing tests. I mean, its a great processor. But video editing isn't "heavy enough" for me to recommend a 16-core or bigger processor.
Ah, not surprised. I have the Intel 8-core.
The best upgrade I’ve made for my video editing workstation has been going to 4x GPUs for DaVinci Resolve.

Most plugins/filters/effects are single-threaded :-(
Yeah don’t get me wrong. They pretty much all are. But, a few key ones aren’t, depending on the host app, and aftermarket plugins have a lot of multi threading support.
