Now that I think about this .. it makes total sense. On the Z series chipsets, you get overclocking, and since the BCLK is divorced from the other busses now, you can overclock freely ANY/ALL Skylake cpus ... if you are using Z series chipset.
No, it's not. It could be, hardware wise. But Intel artificially couples the BCLK again to the other busses on non-K models. This is not well known, because almost noone tests the non-K models. Last week I've seen the first review (!) of one, I think at computerbase.de.
And I claim to know this because I have an i7 6700 since more than a month and can't get the BCLK over 102.7 MHz. Also "Multicore enhancement" doesn't work anymore (i.e. max turbo clock for all cores).
Nope, they're desktop chips. Apple is probably waiting for Skylake-H with Iris Pro graphics, which probably isn't going to arrive until at least the end of this year.
Yes, it's basically an i7 without integrated graphics and with ECC ram just like the E3-1231 v3. Looks like the only difference is the v5 now requires a server chipset, which will likely not make it viable anymore as a lower cost i7 for gaming/home workstation.
Maybe what we get is actual availability and board variety. I've been looking for a non-mITX D-1540 board since launch and have yet to come up with anything, so I'm very interested in the price/performance/power comparison of these chips to those. I'm okay running an 80 W chip instead of a 45 W so long as low-utilization power consumption is comparable. I'm a little worried that even with a 45 W CPU, total platform power might be much higher here, since it's not the dedicated lower power platform that Xeon-D is.
Comparing the 1270 and 1275, it's $9 and a lack of GPU different, but both are listed with an 80 W TDP. If you have the GPU and aren't using it, does it consume any power? I'm thinking it might be nice for setup or troubleshooting on what would normally be a headless server.
ARK doesn't mention AVX-256, which Intel talked about having in some Skylake server chips. (I'm looking at the E3-1280 at http://ark.intel.com/products/88171/Intel-Xeon-Pro... .) Did y'all hear anything different?
I guess you meant AVX-512? These chips certainly won't have that (as they are just rebranded parts from the ordinary desktop line artificially locked down to not work in motherboards with ordinary desktop chipsets). AVX-512 isn't just a feature which is disabled (like often happens with some other features) in desktop parts, but physically not present (so skylake-e5 cores will be really different physically).
ASUS sneaked out 2 server motherboard model # P10S-E/4L and P10S-E/4L that uses C236 chipset and supports Intel Xeon E3-12xx V5 Skylake central processors units.

It's really too bad because the 1230 was always great value, $90 cheaper than the 6700kMrSpadge - Tuesday, October 20, 2015 - link

Really? Damnit, I was really hoping that was not the case!tynopik - Monday, October 19, 2015 - link
anyone else have their OCD triggered by the power column for the E3-1245?johnnycanadian - Monday, October 19, 2015 - link
Yup. C'mon Ian, justify! :-)Ian Cutress - Monday, October 19, 2015 - link

Reckon there will be a mac pro update?DigitalFreak - Monday, October 19, 2015 - link
I believe the Mac Pro uses the E5 series. Those won't show up until next year, though Apple could release a Broadwell based Mac Pro (v4).RU482 - Friday, October 23, 2015 - link
E5 is a server CPU, E3 is a workstation CPU.vFunct - Monday, October 19, 2015 - link
Could these work for MacBook Pros?SirKnobsworth - Tuesday, October 20, 2015 - link

E3-1230 looking good at $250. 3.4-3.8ghz, 4 cores 8 threads. Isn't this almost identical to the i7-6700 (non k)?SoulShadow - Monday, October 19, 2015 - link
That's why they made it only work with the c230 chipsets. It was such a better deal.freeskier93 - Monday, October 19, 2015 - link

i7 6700 runs at 3.7 GHz max all-core turbo and up to 4.0 GHz under single core loads.iwod - Monday, October 19, 2015 - link
I still think Xeon-DE is a much better deal. Any specific features in v5 ( Skylake ) that is useful for server but not on v4 ( Broadwell )?icrf - Tuesday, October 20, 2015 - link

Yeah, AVX-512, sorry. And that was roughly what I figured--"real" server chips to come later.MrSpadge - Tuesday, October 20, 2015 - link
Maybe TSX is finally working? I read that there can be problems with it on Broadwell, too.Morawka - Tuesday, October 20, 2015 - link
wish they made a 25w quad core on mobile.. kinda silly they make quadcores with HT 45w parts on mobile, but the servers get a 25w skylake version.Galatian - Tuesday, October 20, 2015 - link

If I can get a motherboard for these in the $80-$120 range, I'll get the E3-1245v5 over the i7 6700.morrisiriga - Tuesday, October 20, 2015 - link
