Hard to say. My current speculation is that it's an unannounced Whiskey Lake-U part that has lower clock rate than existing parts, but adds a beefier GPU instead.

Going by roughly comparable Geekbench scores, that would sadly mean that it's slightly slower to the two-years-old CPU at single-core (new ~3860 vs. old 4341), and only 21% faster at multi-core (new 10948 vs. old 9084), despite twice the core count, mainly because it's going down from 2.3 GHz to 1.4 GHz. Turbo Boost seems to be better on these, though. Also, built-in Spectre/Meltdown mitigation.

Really, if you want performance improvements, you need to wait until later in the year (and that seems optimistic) for Ice Lake to ship in volume.
Turns out that as usual, Intel's inconsistent as all hell.

Correct assumptions:
  • The CPU wasn't previously announced. It is now in Intel's ARK.
  • It's a 15W part.

Incorrect assumptions:
  • According to Intel, it's Coffee Lake, not Whiskey Lake. Which is odd because Coffee Lake doesn't have any other 15W parts.
  • That also makes it an eighth-generation (not ninth) product, despite having just launched. Whatever that even means at this point. It does have Bluetooth 5.0, like Whiskey Lake.
  • Weird marketing aside, this is really mostly* good news: rather than my estimated 11% slower at single-core, it's 7% faster (it scores 4,639 on average). And rather than 21% faster at multi-core, it's 83% faster (16,665 score)!

That means the processor swap makes a lot more sense now.

*) Assuming there aren't weird gotchas as a result of this not being Whiskey Lake. Doesn't seem like it, though.
