I was wondering if any of you had some input regarding
Z170 i7 6700k vs Broadwell E setup?
I had settled for a I7 6700K but it turned out to be faulty so I had to send it back.
But now I am contemplating waiting for a Broadwell E hexacore instead. I understand it is supposed to be realease Q2 2016?
Currently I can get the MSI X99S Xpower AC mobo for less money than the mid tier z170 boards where I live. (special deal due to stock clearance)

Anyway it would all boils down to the following setups :

I7 6700k cpu
Asus Viii Ranger Z170 mobo
Evga supernova g2 750 w
DDR 4 Corsair Vengeance LPX black 3000 mhz
Samsung EVO 850 SSD


Or

Broadwell E Cpu
MSI X99S Xpower AC mobo
Evga supernova g2 750 w
DDR 4 Corsair Vengeance LPX black 3000 mhz
Samsung EVO 850 SSD
 
What are you planning on using the computer for? If you know you'll make good use of the extra threads from a hexa-core, then I'd say the stated Q2 release date for Broadwell-E isn't too far away to wait for now. Nobody knows what the performance of the processors will be like though, and it's entirely possible they won't prove to be much faster than 5820k/5930k, in which case the wait may end up not been worthwhile. The 6700k is a fantastic for gaming though if that's what you're intending on using it for, and will likely be plenty good for a few years to come.
 
Broadwell-E's IPC will be at least as good as Skylake.

I'm sure I read that the 5775c which is Broadwell has better IPC than the 6700k, but obviously it can't be overclocked as well.

Nope.

Broadwell's IPC on a core by core basic will be slightly inferior to Skylake's.

The 5775C beats the 6700k in some benchmarks due to having 128MB of EDRAM for use as a L4 cache.

That said, Broadwell-E will have more cache than Skylake does, probably the usual 4MB extra on the lower two models like with Haswell-E. This will most liklely let it have almost Skylake levels of IPC in some benchmarks, but not all.
 
OP I would proberbly wait to see how Broadwell-E pans out. Haswell-E once overclocked does pretty well in gaming only behind skylake by a couple of % and crushes skylake when you need the extra threads. I imagine broadwell-E will only close the gap further or make the gap non-existent in gaming and further the gap more in multi-threaded stuff. If it turns out overpriced or poor I imagine the current haswell-e chips would still be good options if they drop in price.

I just hope it's not too good otherwise I know the upgrade bug will pointlessly hit me :p
 
Id wait until broadwell E is released, then you will have a better idea. As it currently stands, in single threaded stuff skylake is quicker, but not by an awful lot. Anything multi threaded haswell E is massively ahead, which is of course understandable due to the extra cores. But wether that will show gains in gaming is still an unknown factor at present. Also consider that there will be an update of skylake known as kabylake. Though probably just a bump in clock speed and slightly improved igpu. The latter imho is a waste of time and die space anyway.
 
The per core ipc of broadwell-e vs consumer skylake will be inferior but each core has more l3 cache memory (2.5mb vs 2mb) so depending on what your doing (and whether you can utilise 4+cores) the broadwell-e could be a lot faster. Skylake would be a little faster in some more lightly threaded apps and games but by a far smaller margin. Ultimately broadwell-e is a die shrunk haswell-e and its performance per core at the same clock speed will be similar to haswell-e (don't expect overclocking to change much either) The £/$ is currently weak and may get worse as well approach the brexit vote so if you can get a good deal on a 5820k now buy that (sub £300) rather than wait for broadwell-e. You can always slap in an eight or ten core broadwell-e or a Xeon down the line

Both are base on 14mn MP. Skylake is the tick to Broadwell's tock. I would expect around 5-10% IPC improve on Skylakes side.

It terms of gaming performance, about the same until you come to heavily threaded games then Broadwell-E would destroy Skylake.
 
I see a lot of Broadwell will destroy all comments, but do we have any data for that? I'm expecting Broadwell to be the usual 3% faster clock for clock but to be useless when it comes to overclocking.

I would wait because Intels I7 6700K pricing is plain ridiculous.
 
if you just game any of the two.

if you do other things once overclocked the x99 platform is quite a bit quicker.
 
I ended up getting the x99 mobo and a secondhand I7 5930K.
Been using it for about a week now and it is brilliant.
The mobo wasn't too expensive and the 5930k cost me about the same as a new 6700k costs and it still has 2 years of warranty left
 
well 6700k is a gamer cpu for sure and bang for buck is the current chip for gaming in most peoples opinion. however in the near future with games in dx12 and moving forward are very likely to utilise more threads there is a distinct possibility both haswell and broadwell will surpass the 6700k. So I am waiting although I am running a 3770k so whatever I do will be a nice upgrade. :)
