Intel's Coffeelake platform launched today and I managed to get the 7920X tested this week as well, so a double update in this post.

Thanks for the heads up. Good that there's somebody doing these DAWbenches.
The struggle is real between the red team & the blue team indeed, we saw impressive developments on multi core fast CPUs. Without Ryzen we'd still having those Intel quad core as a mainstream CPUs.

I was misled for long time thinking that a fast single core CPU is what's needed for a typical DAW, but then some articles I saw about preferring the usage of Xeon multi core, somehow slow clock CPUs in DAWs. So I realized there's indeed a need for such CPU for modern DAWs & VSTs, not to forget to mention the need for a high cache as well to minimize the latency buffer stuttering.

I'm still having my early 2014 PC, with Devil's Canyon i7-4790K. If I would think to make a new build, I'll wait to have 10 core, 4 ghz, overclockable safely to 4.4 GHz CPU. With an increased performance of at least %25 than what I currently have.
And yeah, seems we will see such stuff in 2018.

Thanks. Enlightening reading

That was quick. Thanks!
I'm curious how will Core i5-8400 perform comparing to others, since it's cheapest Intel six-core and may be good solution for cash-strapped people and beginners.

Seem's like my credit card will be less on fire now that the 8700 is available

Great write up, thank you so much

Sorry, lost in the shuffle. Is this kosher with ASIO and what "we" do with computers? I'm not going ryzen or threadripper.

Though newegg doesn't have them, the price point is inline with building a new computer. Sorry if I missed this.

So far, Ryzen & Threadripper CPUs show great results for video & graphic benchmarks.
For audio, music production & DAW application, they sow slow response, big latency, less polyphony.

If you're not in a rush to make a new PC build, I'd recommend to wait more, because within 7 months, we got some of the best CPUs from both sides & at very competitive prices.

Wait more & we will see even more amazing stuff.

Heard that! Yeah, I'm not going AMD, not interested in paying one cent towards anything that isn't a significant improvement over what I have.

If you are interested in buying a coffee lake CPU, you should watch this:

Seems a lot of reviewers update their results. I guess we should've asked ourselves how can a CPU boost 1Ghz or more on all cores, why not sell it with a higher base clock? Well the answer is in this video.

Unfortunately I can't wait any longer il be buying something from scan in December ,I'm using a q9450 so anything will be a giant leap for me , the 1700x still works out about £140 cheaper than the 8700k and making house music I doubt il ever need all that polyphony anyway il speak with the guys first for opinions before I add to cart

It doesn't works well with high polyphony on low latency, but on latency over 4-5ms it's a beast, especially at ~8-12ms. I had a q6600 and I never was able to use latency lower than 6ms with 1 synth like sylenth1. It would start to overload because my E-MU 0404 USB has crappy drivers when it comes to low latency and also USB interfaces can't really handle really low latency. Dunno if they fixed that in newer ones.

With my new 1700 I can go to 2ms and I can use more than one synth, but of course it won't be a Serum with lots of voices, I don't even expect that. Probably with a good pcie card you can use really low latency without problems. It's true, I also have a really low latency system, meaning, overall, other drivers don't cause issues. On my old pc I use to do music using 12-14ms no less than that and I was able to play some keys without problems. But now I can use even lower latency, especially with new Studio One feature that lets you have low latency only on the track you are recording.

I just seen about this chip today. Has crazy overclocking to 5.1. This could be a great DAW CPU. Especially how Hyperthreading on the i7 can be more of an issue than a perk (if it still is an issue), why pay for what we can't utilise?

Edit: My bad... 8600k https://pcgamesn.com/intel-core-i5-8600 ... erformance

Yeah, that's the thing that killed the AMD part for me. I want to run my babyface pro at lower buffer settings. Right now I'm at about 7-8ms round trip, that is at 128 so going down to 64 wouldn't work currently.

I know, I know, 7-8ms!!!!!!!!!!!!!!!!!!!! After all these years though, if I upgraded I'd want to try my hand at even lower.

Going to Zombie this thread for some additional i9 results.

Not being massively well versed in the super-compu-technical, I kinda drifted off here. Grateful if anyone can summarise in a pithy paragraph what it all means for us DAW users.

Also went blind trying to work out what the next processors to come will be, and whether or not they really will be waiting for. The wisdom is always to wait - is it true this time?

And finally - as Cubase user I think I suffer most in single core performance (currently on an stock 4930k). Would an 8700k actually suit me better than a very high core count i9?
