Also, is 5Ghz just an arbitrary number we all hold sacred? So say a CPU with 3X the IPC of the highest overclocked rig out there magically came out tomorrow but doing it at 1Ghz base clock, would it be disappointing?
you quoted him
he was very specific to 2 other users already that his
workload needs max IPC and max clocks
binned 8 or 10 core Intel chips top out at 4.4 Ghz for me here in Germany
if they could go up with kaby lakes better manufacturing process to 4.8 to 5Ghz it would obviously be better no?
I'm already talking about binned chips
also Intel uses solder on those line of chips; no need for a delid
if Intel or AMD could "just" multiply IPC magically they probably would have
also if I need a 10 core Intel monster for work reasons I can write it off from my taxes
so for a living
well I guess that depends on you're tax laws where you live
but then if I need more cores to be productive I'd be waiting on AMD's HEDT as well

AMD achieved a 40% IPC gain over the BD uArch but they won't make another 40% IPC gain with Zen 2 or 3, just as Intel won't make the leap in IPC they made when they went from Netburst to the C2 (Pentium III) uArch.
All gains the past few generations by Intel have been through clock speed and thus IPS, not IPC. AMD will most likely do the same, increase clock speeds with maybe 10-15% IPC increase and that's it. This isn't because they don't want to but because we have reached the limits of silicon. As Intel's co-CEO said: "A new substrate is required and there is nothing in sight as of yet".
Only the very best 7700K's reach 5GHz or even go over so how n earth does that translate into 6 or 8 core KL's reaching those speeds? If it was that easy then in the past Intel's 6 or 10 cores would clock higher than a few hundred megahertz.
temps are holding the 7700k's probably more back
according to silicon lottery 50% or so reach 5Ghz
that's before a delid as they sell that as an extra service
overclockersUk seems to have found the same (45% 5ghz, 20% 5.2Ghz with delid)
there's 3 ways to increase single thread performance
IPC increases; the usual maybe 5%
yeah that's gonna be real slow
agreed on that
if AMD could've increased IPC a lot more in sure they would have
bump up speed
better manufacturing process, better clocks
the more professional line gets soldered, no need for a delid or crappy glue/TIM to hold the chips back
most unlikely to be honest
but by slapping on 256mb of eDRAM, or dare to dream 1 gig of HBM2
that's why he said Kaby with 6 to 8 cores could
clocks high on average (if they were only soldered sigh), some IPC increase compared to broadwell (Ryzen equals broadwell IPC, if it would only clock higher; ehh waiting for Ryzen refresh)
and seemingly that AMD arrangement could mean some interesting shenanigans, maybe

2-4 extra cores might drop it to 4.8-5.0ghz or around that? And that's with solder
a TIM replacement that is as good as solder, some
what is nice with overclockersUk stats is they list the duds
I think it was 3% of 7700k don't go past 4.8Edited by peter2k - 4/24/17 at 2:16am
