Have you tried PBO yet? Curious to see how a 3800X with h2o will boost with the thermal and power headroom in comparison to the 3700X.

I had someone ask me why I didn't go with the 3900X, so I'll post my answer for those curious. This is all personal opinion, all my own theories, just that theories based on experience, not evidence, yet.

This is pretty much just a gaming rig, infact it's attached to a racing simulator. I really don't see too many games that can properly utilize 24 threads. I foresee that concentration of cores in such a small package being a concentration of heat and a heatsoak that no matter the radiator surface area, the block will get saturated by a lack of surface area, if the goal is higher clocks. I like the size of the Threadripper a lot better when you start to get into that kind of core count, the surface area is a big plus. Companies get better at making these chips as time passes, so I was looking for the best binned chips when purchasing early, for now, specs dictate that would be the 3800X. Infact I would have gone with a 3600X and dropped the 4 threads if it had matched the 3800X clock for clock. I'd rather have 4.4 Ghz on 12 threads than 3.9 Ghz on 60 threads, for pretty much exclusively gaming. Can you get a 3700x that is just as good? Absolutely, though I would say it is far less likely in early production. Basically, it's a bit of a premium for a binned chip, you really should have little chance of a complete lotto fail with a 3800X, IMO.

Tnx for sharing, I have different reasons but also waiting to put my mitts on 3800x. As I have great working 2700x now, going to 3700x wouldn't be much of a jump and for 3900x I'm not willing to spend money on. 3800x would be right balance.

No, I can give that a shot though before the weekend is over. Do you have to use the Master software? Or can it be enabled in the BIOS? I'm not a big fan of software controlled OC'ing. I'm not entirely clear on how that is enabled/disabled, I pretty much have all that stuff on "auto" still, so it's entirely possible it is using it, within the "auto" limits.

I'm not sure but it should be available in the bios. Don't have my parts yet so can't say for sure. The older AGESA for the new 3000 series also may have some quirks in regards to power limits on the new cpus, so PBO may be entirely useless until you have an updated bios (just from what I've gathered from certain streamers, no idea how it works on older chipsets).

I think 65% better can be expected once I can open up the memory OC.
Man I am impressed with that performance boost. I also have a 2600x and figured the 8 core would be a sidegrade. That's not be at all. Are you measuring that increase purely from cinibench?

Pretty much, just the math from the Cinebench and CPU-Z benches. The IPC is better per core though, and i'm getting 200-250 MHZ more per thread on multicore benches. I think AMD quoted 13% better IPC, add in 4 threads at 13-15% better and the math works. Assuming what you are doing ever fully loads your old CPU. I have a feeling power consumption is going to come out very close to a dead heat as well, considering the efficiency of 7nm

So how is your overall experience using Zen 2 on the X470 Taichi? How is RAM compitibility?
And as a side how is the bios fan control and all that sort of stuff?

I'm upgrading because I want to throw my asus board into the ocean.
I'm pretty well decided on the X570 Aorus Pro Wifi but if I can save $150 aud that'd be way better.. I just don't want to buy a new board and still end up having RAM issues waiting forever for bios/agesa updates.
