[GTALUG] processor progress sure has slowed down

I got an ad from NCIX for systems with Intel's new Kaby Lake processors.
Here's the headline:
UP TO
[LARGER FONT] 28% BETTER PERFORMANCE* [/LARGER FONT]
versus a 3-year-old-desktop
The footnote shows that a i7-7700K processor system was being compared
with a i7-4770K. Some of the improvement would be in DDR4 vs DDR3 and so
on. OS and video card were the same. The power requirement of the CPU
went up slightly.
You'd normally expect a 7xxx processor to be compared with a 6xxx
procecessor, but they've reached back an extra two generations to show
even a modest 28% improvement.
There are useful features added to the processors since the Haswell
generation. Like a working TSX-NI: Haswell had it, with bugs, so Intel
suppressed it with a microcode update. Not completely fair since the K
models never had it.
Intel has put a lot of extra transistors into on-chip video, something
useful at least sometimes. Perhaps this shows where Intel feels it needs
to compete -- AMD has a better on-chip GPU but an uncompetitive CPU. One
can only hope that AMD's Zen/Ryzen lives up to AMD's talk.
