Skylake & Skylake X

Hi,

Is the Skylake X architecture just the same as the Skylake? - With 6700 K which is Skylake and other CPU's such as 7820X/7900X which are Skylake X - Is the architecture identical apart from the different cores numbers and also a different platform & socket?

Reason for asking is a clock recently done on 6700 K was tough going compared to the 7700 K and as I have a Skylake X chip just thought I'd ask here, so if anyone reading this has had experiences of both please mention them, thanks

The X CPUs are HEDT, different socket, with quad channel memory, and some other differences. The CPU core architecture is the same though.

The difference between consumer 6000 and 7000 CPUs is only in binning. The 6000 HEDT is not Skylake-X part, its Broadwell-X (aka, HEDT CPUs from the 5000 series).

Yes I realise it's a different socket eg - Intel socket 1151 & Intel socket 2066 - The query is would I struggle to clock the 7820 X

The 6700 K took 1.440_v_to reach 4.5 Ghz which was way higher than a Kaby 7700 K [email protected]_4.6 Ghz - This is why all of a sudden there was concern about the 7820 X and OC'ing it and wandering if it'd be as difficult as the 6700 K!

As i said, the 6000 series consumer CPUs are first iteration of Skylake on 14nm. The 7000 series is 14nm+. This is where the difference in the voltage/CPU frequency ratio comes from.

Also, since the HEDT comes with quad channel IMC, and a different cache (also, the 7820X has actually twice as much cores compared to the 6700K) , it is expected, that the voltage required, will be significantly higher.

Its much lower .
7820x 4.5ghz ranges from 1.04-1.05(the best bin u can get) to 1.18-1.2v ( the worst end of range) but generally most of them do [email protected] .. (avx offset 2)

If you are buying used. Ask the seller to load everything as per default load into windows. Load with prime95 avx disable fft 8. Hwinfo vid voltage screen shot. Should be 4ghz all core load..Whatever voltage you see there add 0.024-0.05v depending on your loadline. Instant presto 4.5ghz offset 2. 7820x the most important core that has to be exact in voltage per core overclocking is core 3 and 4 (0-7)

Hi,
79..x series needs delid otherwise it's best for a space heater in winter limited all core clocking until delid needs custom water loop.

99..x series is soldered chip stay away from the 9900x it's pretty much a defect 9940x up are okay I'm on my third 9940x atm first died on startup second was just bad core temp spread so rma'ed

109??x well it's a weird release cheaper soldered so no delid needed but still a space heater like all others clocking again like all needs custom water loop.
