    I just picked up an i9 9940x which has 14 cores. I used to be able to run an old Dell 8700 desktop with a 4 core processor at 3 GHz, 64 GB of RAM, a couple SSDs, an GTX 970, a Lynx AES16e, outboard reverbe, running a very large template (2700+ midi channels, 18-ish VEP instances) in Nuendo 8 with 2 VEP slaves, all at a 256 buffer, sometimes at 128. With more activity in the session, sometimes I'd need to bump it up to 512. Nuendo's ASIO meter is usually about 2/3rds the way up.

    On the new, arguably beefier machine - 14 cores at 3.3 GHz, 128 gb ram, AMD GPU, more ssds, same DAW, VEP slaves and hardware... 256 gives me pops and clicks with just a piano patch, so it's up to 512. Asio meter is barely 18% and never red lines.

    Not sure what it is. In reviews on Anandtech, I've seen indications that DPC latency is generally higher on the x299 chipset than on say, Z390. If I had to guess I'd say it's that the drivers are immature and the hardware is too new. Hopefully over time this improves, but who knows?

    Wow -- good example of how all this stuff feels at times like alchemy. Sometimes you get the gold, sometimes the dross.

    I think what I’m going to do is buy a 9900k or 9900X and see how it performs. The X299 motherboard I’m thinking of buying (Asus WS Sage/10gb) allows me to use any of the x series i9s so like the option of upgradability is always there. Having Slave computers for sample lifting really does help and when I finally use a TB3 PC, I can then get an UA X6 interface finally using UAD sattelite cards which takes even more pressure off the main computer.

    Both 9900k and 9900X seem like very fast CPUs and much cheaper than a 9980X.

    Unfortunately not - neither are on-board. I use an Intel X540 10Gb nic.

    If you want a main machine on Windows 10 with lots of juice for low latency DSP and cost efficiency is important to you, the i9 9900k is definitely the best thing ATM. For sample slaves, it might be a bit different, as voices do profit from more cores. If a 512 buffer (which is what you get with the VEpro 2x setting and a buffer of 256 samples) is alright, the best cost efficient machine could even be a AMD TR2. They show very good numbers on voices, if you don't throw in too many CPU intensive plugins ... it all greatly depends on the exact use case ... but the 9900k is a good competitor in any way. It just doesn't get your Kontakt voices all the way up, as some of the more expensive processors do.
    I think/hope we will see this or next year a generation of processors, that will easily handle the voice needs. The AMD competition will push Intel and AMD will be ambitious in areas where they were not able to beat Intel yet (Single core performance). IMO, if there is no immediate need for a new PC, at this point it will be best to wait till Q3/4 of 2019.

    The benchmark on the 16-core i9-9960X is slightly higher than the 18-core 9980XE. This is only one rating of course, BUT, the 9960 is $700 less:

    https://www.cpubenchmark.net/high_end_cpus.html

    It's also important to look at price per increase... my 14-core 7940X scores at 25,406. Cost me $1100. The 9980XE scores at 29,506. Costs $2400 for only a ~17% gain.

    If I were to build my rig today I'd probably save a grand and go for the 9940X... Under $1500, 14 cores with a 27,173 benchmark score, 9th gen cpu and faster 3.3GHz core which is great for processes that aren't multicore. Your single thread get 10% more speed than the 3.0GHz 9980XE. Oh, you save a grand too!

    I wanna also upgrade my: GA-Z170X-UD5 TH
    Could you guys advise me the great MB with Thunderbolt 3 on board with support 9940X, 9980XE and more...

    I haven't done all the math, but is it possible (in view of the prices for these super-duper CPUs), that you could build two i9-9900k satellite PCs for about the same price?

    I'm a fan of "many" as it spreads the load out over multiple computers -- the bussing, the CPU load, the "everything" load. When the original EWQLSO came out they recommended eight PCs to run it full-throttle; I bought six at that time.

    So having "only" three PC satellite computers today seems like a luxury, by comparison.

    Is there any website that offers information on how latencies are on MBs?

    That's why my golden rule here in the studio is to always purchase previous generation gear - it's a little slower but much safer.
