Postby jeffswitzer; Thu Aug 10, 2017 10:48 pm Threadripper or skylake i9 for vsts

Looking to build a new rig soon and am trying to get a feeling for whether x299 or x399 is better a platform for many layered vst synths and effects. Are more cores or higher clockspeed more important? What about AVX-512 instruction set that only skylake has.. is it useful for vsts? One thing I just realized is that thunderbolt is an Intel thing so threadripper doesn't support it for now which is a bummer because a thunderbolt audio interface would be nice. I uhe plugs like bazille and diva which have multicore switches. I also heard that there is some kind of latency overhead with threadripper connecting two chips. Anyways does anyone have any insights / clarifications?

I'd wait to see a bit for the specifics on how threadripper behaves for audio first, since it is so new. So far though, it looks like TR is the fastest cpu on the market according to some cpu benchmarks, how it plays with daws is a bit too early too tell afaik.

Both have more power than you need.

However, if you plan to use VST insturments, they can swallow any number of thread you give them.

Nope, there is a share number of vsts that do not have multitread support, even new ones.

A single VSTI doesn't need to have multi-thread support, DAW has. Every track in a project can use its own thread.

Well I see the AMD threadripper is in the number 1 spot on Passmark's High End CPU's (26350), even beating all the Xeons. Although the margin of error is high, but still.

Sadly out of my price range (and power consumption range!), but I guess the effect is that it will trickle down into the lower price CPUs, which is already doing well thanks to the other Ryzen chips.

Anyone on W10 should be wary of this:

"Threadripper ~= i9-7900X in most things, simply rips at rendering, and falls curiously hard on DAW stuff. More later"
Full techreport.com review coming soon, but I would wait for Pete from Scan to test and tell his story before buying anything.

I'd have thought single core performance is almost as important as number of cores depending on the VST

I often feel like with my Xeon quad core music setup, that all 4 cores aren't being used fully, yet 1 or 2 cores of CPU are maxed out and I'm getting VST issues

I haven't tried but I'm fairly sure if I did it on my gaming system (3770k @ 4.4 gig) it would cope much better

Yeah it very likely would, because Xeons don't have 4.4 GHz cores. :P

Gotta wait n see if threadripper does shitty rt work cus of mobo or chipset drivers or if its an arch thing. Hope that techreport guy gives the grit.

Wait for the 32 core version, nah, f.. that, wait for the 64 core version.

Coffee lake 8700k is another option I hadn't really thought about. Would be capped at 24 pcie lanes though.

This sounds interesting with coffee lake:
Intel is also making the biggest change to onboard audio standards since the 15-year old Azalia (HD Audio) specification. The new Intel SmartSound Technology sees the integration of a "quad-core" DSP directly into the chipset, with a reduced-function CODEC sitting elsewhere on the motherboard, probably wired using I2S instead of PCIe (as in the case of Azalia). This could still very much be a software-accelerated technology, where the CPU does the heavy lifting with DA/AD conversion.

Jeff Kampman at TechReport has stated there are issues with ThreadRipper for audio workstation use. Not that it can't, but that it seems to perform poorer than it should.

With TR and Ryzen it would be worth waiting for platform issues to be resolved before building a system around them.
