This is strange to me, how could it be that the 10900k performs worse than the 10900x?

It's a different micro-architecture and the X299 chipset is sitting somewhere between the server range than the consumer range, so whilst they are all closely related there are differences in the silicon. You've also got double the memory bandwidth to work with, one of the reasons we're going to look at RAM overclocking again and how spreading the load affects it.

Very interesting. One other question, would Ryzen still hold the lead like in these results when you have fx like Ozone on the masterbus, or recording live tracks? I only ask because of the difference in single thread performance.

With the masterbus effects chain, or indeed any channel effects chain I would be concerned for getting enough performance across all threads to support what needs to be done on each channel. It can be a problem when running low powered chips where threads might get spun down to the low 1.*GHz's and suddenly a heavy effect chain gets thrown at it for processing, but we're not working with any chip here that's going to be spinning anything down anywhere near that low.

The chips all generally have high headline single core turbo speeds, but those are not what we're looking for here. It's more about what the chip can do as a constant and all of them were holding their all core ratings which tend to sit between 4.2 and 4.7 depending on the chip in question.

The DSP test would be the closest we have here, but only when comparing the cores like for like. For instance the 10700k vs 3700X or 3800x has the 10700k coming off better at the 64 buffer (although, still neck and neck with surrounding models) than it tends to manage as the others scale up at higher buffer settings.

However, the single threaded performance question is dependent on the workload in question and how well the software is able to put all this into action. The general synthetic single thread benchmarks are fine in isolation, but they don't reflect how your software is going to be working with the chip in real-world terms. Running a test within a real-world application works better for our needs here, but there are still possible variables to be had between sequencers and even different plugins depending on how they've been optimized by the developer, so all we can do is a set a baseline and measure against it.

The big kicker for the single thread question is that none of these chip cores are running truly single thread only as they all feature SMT or HT so it muddies the water somewhat. You might see a clearer difference if we disabled those features, but then you'd also lose a chunk of performance overall.
