Ok. 60% after 8 years. Compare with P4 -> Core2 140% efficiency jump made in 6 years. We see shame anyway.
If you'll look at Trail Bay Z3736G - 4 cores, 2.16 GHz, GPU, low TDP - it costs $20 only! It has artificial limitations like some options not included or blocked, microcode and MB BIOS with settings wich reduce its speed without good reasons, the frequency wich I'm sure can be ~1.5 times more with close selfcosts for the producer. Now look at 6700K sold for $340 - it's very close from producing technology side, but costs 17 times more! Besides strange technology stagnation the producer may to get astronomic % of profit, wich may be masked or lied in official reports (with help of state bureaucrats this may be done easily, while strategic and big producers have links with them). Such situation lasts from middle of 2000s.
my q6600 ran on 3,2ghz in 2007
in 2007 there were already 4 core CPUs wich overclocked on typical ~30% to get ~4 GHz. after 8 years we have same 4 cores on same 4 GHz wich work only 60% faster, but have top prices >$300. near on a shelf are same CPUs underclocked and with cut some options with their real price ~$20
like DX12 has a huge boost thanks to multithreading
When DX12 games will massively appear a possible huge boost may be explained by that most of these games were made for consoles on 2010 year level of technology. While I'm not sure in "huge boost", even if it will be possible technically. Like recently we din't see "huge boost" in games made for ancient Xbox360 wich were ported to modern computers a couple years ago.
