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.

Well at the same clock the 7xxx and 6xxx are apparently the same speed in almost all cases. 7xxx is a bit more power efficient though, and can hence overclock a bit more. But yes, not a big leap this time at all. There is a new chipset generation to go with it, although apparently some of the existing 100 series boards can already support the new chip at least with a bios update.

Well at least on some models they are improving graphics, but I am not sure that is the case on all models. I still have a happy Core2 Q6600 running, which was released 10 years ago, and I would not consider it a slow machine. Sure it doesn't match my i7-3960X machine, but that would not be a fair comparison anyhow. -- Len Sorensen
