Basic Skylake 6700K Overclocking review and performance.

I have a 4770k @4.4ghz and a TX and I think I might just go 6700k after all. I can always re-coup some of the cost from selling my current gear on the MM as well to help fund it
 
No expert, but I will argue for a gaming PC, the 6700k is the way to go.

Why? Base frequency and OC potential are higher on the 6700k rather than the 5820k. And to OC the 5820k you are pretty much going to need some seriously robust cooling.

DX12 is a little complicating factor as it does scale up to 6 cores (from what I've seen), however the 6 cores on the 5820k will be in generally of a slower speed and of a lower IPC than the 6700k.
Oc potential on skylake isnt that great looking tbh, 4.5/6 ono going by 8 Packs findings. Looks to match a 4790k at 4.7ghz, which is pretty much standard for that chip. Also, due to being a non soldered ihs cpu, the 6700k like haswell and ivybridge before it will likely run hotter than the 5820k.
 
Skylake isn't a poor chip its the price that's the issue. It should be £250 for the I7 6700K. At £320 (seriously 300+ for an i7!) Intel have put it squarely in Haswell E territory. A small IPC gain against 2 extra physical cores is a tough choice for some and a no brainer for others.

Nice review from 8Pack.

For 4.5Ghz on the 5820k your going to need some serious cooling. Not just standard air.

It's a truly hard choice, as it seems ludicrous to not go 5820k with SIX cores and 12 threads.

This is what I hate about tech reviews, different sites and different reviews show slightly different results.

Good air copes pretty ok for haswell, (alpenfohn k2 here). Maxes at 76c in games, 83c under real bench at 4.7ghz. But haswell chips (Devils canyon included) run a good deal warmer than anything else intel produce. If buying new now, id go the X99 route, can actually work out cheaper than skylake, extra cores may be useful under DX12 too.
 
As a gamer the 4790k/6700k is tempting, but the possibility of the 5820k being better for the future is just far too strong. I'd rather take the 400MHz less for 2 cores/4 threads.

I think my decision has been made - Roughly 2 weeks until I can afford it.
 
I keep feeling that dx12 will not be the magical thing so many believe it to be. Firstly game developers will have to implement it, secondly, how many dx12 games are on the horizon? So far just one. I predict that the GPU will remain the thing to offload tasks to rather than the CPU, makes more sense IMHO. By the time that those few rare dx12 games utilising more than 4 cores games arrive Skylake-E has arrived. Meanwhile Haswell-E owners might be playing games with 2 cores and twelve threads just sitting there and lower clocks, thus actually losing performance a higher clocked quad core offers. Hence I feel that Haswell-E remains a workstation chip and not a gamer's choice. But hey, maybe I'm wrong :)

:p

Yes yes. You have a point. I said much the same above. Choices Choices ....

If it wasn't for Dx12, the choice would be easy!
 
Seen a few folks mention Asus X99 Deluxe, word of caution there are two different versions of this board, you might want the newer usb3.1 version.
 
With X99, you get all the same benefit for gaming as you do on the mainstream platform, but for other tasks such as editing, encoding etc is where they really shine. Take the X58 bloomfields, (along with the now very cheap hex cores) they were the high end part of intels lineup, with lynfield being the mainstream. The X58 setups were great gaming and all round use systems.

Isn't the only difference between the 3.1 version the bundled add-on USB 3.1 card? Is that not available elsewhere or something?

The regular X99 Deluxe is USB 3.1 compatible if you can acquire the add-on card, and the X99 Deluxe/U3.1 has no native USB 3.1 ports, just the two with the add-on card which comes bundled with the latter..

What I'm worried about is clockspeed and games.

TinyTom says in this video that the 3.6Ghz turbo of the 5820k is only on one core and it will usually only do 3.3-3.4Ghz on all cores.

Where as the 6700k turbos to 4.2Ghz on all cores if Im correct.

Listen from 6.20mins


From about 16mins on he goes on to say, these are not really gaming chips etc...

You can get an i7-5820k to 4.2GHz with a decent air cooler, I've heard of people getting 4.6+ but you could be unlucky at the end of the day.

Yeah I've seen Tom's video, not a lot of love for the 5820K. The entire Haswell-E range are cut down Xeons, no, that were in fact released well before Haswell-E was, making the platform even older (because, what's in a name eh?). I think the 5960X eg actually has the full 12 cores 24 threads with 4/8 disabled?
 
Thing is with TTL's review that it doesn't account for the lower price of 5820k now (obviously not his fault, the review is 10 months old) and the fact that Skylake is pretty much the same price and also requires DDR4.

Pretty much all 5820k will hit 4.4ghz. All that seems to vary is how much volts and hence heat it needs. I got lucky. Mine does 4.5 at 1.25v and I haven't really played with it much to see if it goes even lower on the volts. Total rubbish about the turbos. All my cores run at 4.5. I think he's talking just about at stock.
 
Has anyone seen a review of Skylake yet that has minimum fps and frame time game benchmarks, with the 5820k there for comparison?

I'm still curious to know how well it does in minimum and average fps consistency.

Does the increased clock speed and ipc give it better minimum fps and more consistent frame rates compared to having more cores.

If overclocking a cpu is anything to go by, where it does just that, it should do the same in the scenario you ask about.
