Has anyone tried the new Ryzen? It seems to match the single-core performance of the i9-9900K for a fraction of the price.
We're looking at potentially building on the new x570 platform. For the Ryzen 9 3900x (4.6 GHz max boost clock) the single core performance is lower than the I9-9900k but the extra 4 cores and the the new PCIE Gen4 make makes me wonder if AMD might be the better system for large assemblies/drawings. The new PCIE Gen4 lane can deliver Sequential Read Speed or up to 5000 MB/s and Sequential Write speed : up to 4400 MB/s. That's double the current speed of Gen 3 Nand ssd's drives!
I'm currently debating between the two setups below which are around a $100 CDN of each other.

Did you buy a system? Which did you choose and if you have it setup how is it performing?
We haven't yet reached a decision yet, still sitting on the fence. Also AMD is releasing AMD Ryzen 9 3950X in September which looks interesting. I'll keep you posted.
You should compare i5-9600K with the AMD Ryzen 5-3600.
For 10% overall gain, the i9 is not worth the price.
With all the patches Intel need now, their CPU get slower.
Also look at support chipset, bus and memory, speed and bandwidth.
New article out by Puget Systems. Comparing 3 Ryzen against 2 intel cpu's on SW2019sp3. Some interesting results.
The i9 with HT and 300MHz higher clock got 10% faster than i7, on file open.
Thanks for pointing that out. Interesting that the single processor speed increase is only 2-3% better. From what I have seen I believe multiple cores are used to load the model into RAM. Seems likely this is due to no Hyper Threading on the i7-9700k so it is only working with 8 cores instead of 8+8HT like the i9. Seems like a good idea to test HT on recent hardware and SW releases. I remember at one time there was a suggestion to turn off HT for better performance but I think that goes back to when it was new technology.
There is always overhead to manage parallel, multi-thread execution.
I think sim recommend HT off.
It is not simple. Google still struggle with core scheduling in Android.
