Intel Core i7-7700K Kaby Lake Review

Mark Walton (Hacker News):

The Intel Core i7-7700K is what happens when a chip company stops trying. The i7-7700K is the first desktop Intel chip in brave new post-”tick-tock” world—which means that instead of major improvements to architecture, process, and instructions per clock (IPC), we get slightly higher clock speeds and a way to decode DRM-laden 4K streaming video.

There are apparently power consumption improvements, however.

Dan Luu:

Dear linkbait authors, I’m pretty sure Intel is trying. If you look at research $, they appear to be trying exponentially harder over time.

Marcel Weiher:

We are in an effective post-Moore’s law world, and have been for a couple of years. Yes, we can still put more transistors on the chip, but we are pretty much done with single core performance, at least until some really big breakthrough.

[…]

Most of the things that go into squandering CPU don’t parallelize well, so removing the bloat is actually starting to become cheaper again than trying to combat it with more silicon.

Lloyd Chambers:

[There] are at least a few reasons why the Intel ‘Kaby Lake’ release is significant:

  • Improved graphics performance.
  • My understanding is that the Kaby Lake ‘H’ series supports 32GB memory, thus making a MacBook Pro with 32GB of DR 23000 DRAM possible. But whether the power draw is viable on a laptop is unclear (meaning what we could expect from Apple, given the rationalizations seen with the Nov 2016 MacBook Pro).
  • The i7-7920HQ 3.1 GHz (turbo boost to 4.1 GHz, 4 real CPU cores) might be suitable for a MacBook Pro.
  • The i7-7700K 4.2 GHz (turbo boost 4.5 GHz) shoudl be suitable for an iMac. This perhaps is the “standstill” point—that’s only 5% faster than the 4.0 GHz iMac 5K that sits on my desk today—at the cost of a 95 watt TPD.

Paul Haddad:

Every PC manufacturer today announced Kaby Lake updates. I’m guessing Apple will wait until at least April to announce a MacBook with one.
