I got asked about this, so here's some data showing the phantom throttling at stock settings. The pink entries are the ones with phantom throttling.

Skylake X and AVX512: (July 6, 2017)
Not all Skylake X and Skylake Purley processors will have the full AVX512 capability.
"Phantom throttling" of performance when certain thermal limits are exceeded.
Memory bandwidth is a significant bottleneck.
Amdahl's law and other unknown scalability issues.
Not all Skylake X and Skylake Purley processors will have the full AVX512 capability:
While this reason doesn't apply to my system, it's worth mentioning it anyway.
 
However, that dedicated 512-bit FMA is only enabled on the Core i9 parts. The 6-core and 8-core Core i7 parts are supposed to have it disabled. Therefore they only have half the AVX512 performance.
 
It's worth mentioning that there is a benchmark on an engineering-sample 6-core Core i7 that shows full-throughput AVX512 anyway. However, engineering sample processors are not always representative of the retail parts.

Version 0.7.2 and AMD Zen: (March 14, 2017)
I went through a lot of trouble to do this in time for Pi day, but here it is. y-cruncher v0.7.2 has a new binary specifically optimized for AMD's Ryzen 7 processors.
 
 
 
 
 
As for the Zen architecture itself. Here are my (early) observations:
256-bit AVX instructions are handled efficiently enough that it seems to be beneficial to use 256-bit instructions when there's no overhead to doing so.
Memory is huge bottleneck. Latencies are very high and dual-channel memory is simply not enough to feed this much computational throughput.
For software developers, compiling code on the 1800X is about as fast as the 5960X at stock clocks. But the 5960X has much more overclocking headroom, so it ends up winning by around 15%. For a $500 processor, the R7 1800X is very impressive.

y-cruncher v0.7.1: (May 16, 2016)
This is an semi-unplanned released to address a number of critical issues with the HWBOT integration. (Most notably the reference clock skew issue.)
While this version wasn't intended to have many new features, all that refactoring did lend itself to a some opportunistic stuff such as large pages and Unicode support.
Full list of changes here.
GUI Benchmark Wrapper and HWBOT Integration: (April 3, 2016)
I get asked these two questions a lot:
Why don't you add a GUI for y-cruncher?
Why isn't y-cruncher on HWBOT?
#1 never happened because I suck at UI programming and I didn't want that mixed in with performance critical code.
#2 never happened because the HWBOT benchmark API wasn't ready.
Well, both finally happening... More details here: http://forum.hwbot.org/showthread.php?t=155079
