I couldn't find a clear summary of the advantages of X470 vs X370? Anyone know?

The leaked benchmarks prove that there's minimal IPC gain, which was to be expected because this isn't a new architecture, it's a minor tweak for the new process;
Also, this new process that seems to have released very little additional clockspeed headroom at the high end. 5% clockspeed increase for an 11% TDP increase seems like a terrible result, if you ask me.

If you want single-thread performance you're buying a CPU from the wrong vendor - the $86 Pentium G5600 is going to give you the same performance as a 4.35GHz Ryzen as long as you only want one or two threads at that speed.

I can be a very patient person. I sat out last year, I can sit out another year (or two, if necessary).
The industry is still out of whack.

It also seems silly to not buy a high end CPU because the savings you make by picking up a lowly Ryzen 5 2600 instead of a Ryzen 7 2700X are eclipsed by the extra $450-650 you need to spend on the rest of the platform (depending on 16GB or 32GB of DDR4)

AMD doesn't care how rational the buyers are as long as the check doesn't bounce!

I have an R7 1800X running at 4.1GHz with an overvolt to 1.375V and that's without XFR, so it's directly comparable to the 3.7GHz base clock of the 2700X.
For the record, 1.375V increases power consumption by around 20% (P=I^2R) so my 1800X is running at an approximate TDP of 115W, using this hand-wavey metric, and it holds up against the new 2700X in multi-threaded workloads.
1800X all-cores (stock) 3600MHz + 100MHz XFR at 95W = 25.7W/GHz
2700X all-cores (stock) 3700MHz + 50MHz XFR at 105W = 28.0W/GHz
1800X all-cores (OC'd) 4100MHz + XFR disabled at 115W = 28.0W/GHz
Sure, the single-core peak clockspeed of 4.35GHz is better than the 4.1GHz that was possible on an 1800X or 1600X, but that's not really what Ryzen is about.

I hear what you're saying but don't forget that these second-gen Ryzen's aren't hitting 4.3+ GHz either. That's a single-core, temporary peak boost speed, which we won't know more about until after the reviews. The highest all-core base clock that is comparable to an overclocked first-gen Ryzen is the 3.7GHz of the 2700X.

Been there, done that... 5 years in the U.S. Navy was enough "patriotic duty" for me.
