Note that I am only interested in top 24/7 oc stable speed in an ok quiet system. Die hard Skylake folks, skip this.
14nm Broadwell and Skylake is a severe disappointment even for someone with SB.
A little bit of history. My old i5-2500K hit 4.7-4.8 summer/winter. Switch to i5-4690k because of pci-e 3.0 and old mobo is not optimal for multi-gpu 16x + 4x. 4690k hit 4.5 at 1.3v on Noctua D15, fan speed set to low, p95 small fft hit 90C, 24C ambient, V71 case all case fans low. Not really a speed upgrade at all overall and I know it before the purchase. I bought the Z97 mobo just in case Broadwell is any good.
Since my 22nm Haswell at 1.3v is already toasty at 90C with Noctua D15, although not a realistic scenario for most workload, any result above 1.3v become unrealistic for 24/7 on a dual fan D15 which is very respectable already. My realistic expectation for Skylake is 4.4-4.5, but 4.6 is looking like it need >1.3v pure guess base on leak which is not achievable on most 24/7 setup due to the even smaller 14nm die area to cool vs Haswell. That 5.2GHz smell like controlled leak, Skylake is an oc'er Dream, TM Fury X.
Intel and exchange rate is giving me a big reason not to bite on this
1) they would have had enough time to fix the garbage TIM and go back to Solder (don't care your reasoning, just do it, last thing I want to hear is saving a few cents if that's the reason, any other technical difficulties, go figure out yourself, that's your 60% profit margin problem.)
2) If you have Broadwell with those EDram today, can I have it on Skylake and not wait a year until Kabylake, that 1GB ram iPhone piss me off as that's a pure cash grab to force people to upgrade yearly. I am willing to pay Broadwell price for those EDram SKU if you release it now.
3) 1 US$ = 1.32 Cdn, AUD, JPY, EUR, NZD, oh my :'(
$316 6700k + $160 mobo + $250 32GB DDR4 2666 CL15 Ram (for reuse in future build, so not cheaping out) x 1.32 ~ $960 + 13% tax = $1080Cdn
Sell 4690K 250Cdn + 100-120 mobo + 12GB DDR3 from SB build $75 ~$430
Cost of upgrade: $650 gives 20GB more reusable ram, 4 more thread, maybe 4-10% ipc not doing any video encoding. Same top oc speed.
vs
Buy 32GB DDR3 $230 Cdn, Sell 12GB DDR3 $75 = $155Cdn
Diff $500Cdn for 4-10% performance - fun for new toy, stress for selling parts... No thanks.
Looking forward, Zen 8c16t is my next target. But having seen how even Intel have problem scaling beyond 4GHz on 14nm on a 4core product, really good luck on 8C Zen , but it's getting tired with Quad core 8 Thread mainstreadm K SKU, finish milking this already. The X99 mobo is way overprice, I only need more core on a basic mobo.
