I can't tell you if it's 100%. In my case, never was a problem with any type of hardware. For sure Zen 3 is known by all companies and they take that CPUs as serious as Intel now.

Yep, with every current geneneration we get around +15-20% IPC increase (in general INT, FP etc). So, if someone change CPU after 5 generations will probably have 50 - 80% IPC boost per core. Which is very reasonable result worth spend money, and quite significant performance boost. As in my case. Will see what brings nearest years. New AMD Zen 3+, 4, 5, Intel Alder Lake and next generations. For me 5900X is enough for everything at this monent.

Thanks for article. I know dawbench and used many times their SGA 1156 test on my computers. Very usefull From my experience overall architecture of CPU (cache speed and amount, internal cache latency) and pure single core performance is a key factor for perfomance in small asio buffers. On my previous CPU I could not work on advanced mix nor arrangement in Hybrid Engine with 128 Asio buffers. Now on 5900X I'm able to mix and arrange all the time on 128 buffer with no glitches and lost asio buffers. There was only CPU change. There was around 50% IPC difference between old and new CPU per Core. Low internal latencies, big cache did a job. This was also good site with benchmarks. But unfortunately they stoped on Intel 10gen and Ryzen 3000 http://www.scanproaudio.info/

Hi Bob. Could you expand your thought?

If 16GB is enough for you it ok. Memory amout does not speed up your CPU perfomance. But you reach maximum of phisical memory, then system eill get hiccups. So you need to know how much memory you are able to use. In my case 32 GB is ok, because I use VSTi sample libraries. If only mix, 16 GB should be enough. 64 GB is too much - you will not use it probably.

Nothing special. All mother boards work similar, with all Ryzen 3000 and 5000 series. For 5900X You should look at motherboard with X570 chipset, DDR4-3600 Mhz, and the rest is up to you (USB, port, wifi, slots, m2 amount etc). I'm sure you'll find your best MB. Note that AMD CPUs have no iGPU, so if you don't have GPU card you need to buy something. Generally yes. Better single core always means less less susceptibility for bottleneck, as you experienced. Performance headroom is bigger. Multicore give you more possibilities to scale your project on more threads. So it's also good to have as many core as possible. 10 - 12 fast cores from my observation is the best solution. I can work with 128 buffer with no glitches almost all the time with VSTi.

Nope. Single core performance is very important. 10900K has no the same performance. Is significantly slower than 5900X. https://browser.geekbench.com/v5/cpu/search?q=10900K https://browser.geekbench.com/v5/cpu/search?utf8=✓&q=5900X

This is when I put a lot of Ozones on master track. First core overloaded. But still my CPU can handle that. AMD Ryzen 5900X, which is around 50% faster than yours in single core. Your CPU should handle your project easy. You need just optimize it.

You can divide your master chain into several sub groups (BUS). Not AUX - you don't need parallel processing, but serial. So you can route all you tracks to first BUS, put there some plugins, from this BUS to second BUS etc. That divides your chain into threads. That amount of Ozone plugins for sure would kill my DSP when I would put them on master track.

That should work. But first of all check if your master track does not have too many requiring plugins - it often is a reason of quick DSP saturation. Could you show your task manager during playback that project shown in previous post? How many cores you have set in performance settings?

Nope. DSP is only name used in Samplitude (Cubase has "ASIO performance" meter etc). For every DAW, CPU is the only compute unit to calculate. It's universal unit able to to compute every type of data. When it comes to DSP vs CPU meter. Did you switched your CPU monitor into logical cores? I described how DSP meter works in previous post when I commented this screen: As you can see, one of CPU thread is loaded around 50%. And DSP meter shows that value. Reason? Some track in the project generates that higher load and is allocated in 2nd thread by DAW. Remember - one track can be calculated on one thread. So when you put on some track too many plugins you will overload some thread, then your DSP reach 100% despite the rest of CPU cores has free resources. To be able load all cores in more balanced way you need to remember about that rule. Just optimize your projects (freeze MIDI obejcts etc), or change CPU, buffers etc.

Switch your task manager to show individual threads of CPU. Then you will see which thread is loaded more than others. That determines DSP headroom. Windows has nothing to this. Multicore utilize is only DAW matter.

Dsp is not the same as CPU load in task manager. As you can see, second cpu thread is around 50% utilized and your dsp metter shows exactly that. It does not mean that you add some more plugins on several tracks and dsp ussage will increase. If that plugis will be calculated on another thread the dsp metter won't show increasing. Unless another thread cross value of ussage more than 50%. Then you'll get higher dsp ussage. For example - when put on master track heavy mastering plugins, you are able to overload dsp system becauae one track can be calculated only on one cpu thread. General Cpu metter will show small ussage. Thats why it's worth to look at individual cpu core ussage to get more precise info. Lukas

Hi Guys. My new single just has been released. Leave some comments on Youtube. Thanks a lot! https://www.youtube.com/watch?v=1i72NfbXRF0 Spotify, TIdal, Apple Music, iTunes etc: http://www.soundline.biz/OZDMyRoots/
