Haswell -E Core i7-5960X, 5930K, 5820K specifications

[silvagti]

So which chip is looking like it'll be the buy then?
I was thinking the 5930K, but I see a lot of people saying the 5820K.

Personally the 5820k is the only one I'd consider. I'd draw the line at spending any more than £300 on a CPU and the 5930k is just a faster clocked 5820k from what I've seen. Given the 5820k is already unlocked I don't see how anyone could justify spending hundreds of pounds extra for and extra 0.3-0.4 Ghz.

5820K is only 1x16 1x8 1x4 PCI-E.

Oh how I miss the days before artificial PCIE limits.

 

[xixou]

You also get 40 pcie lanes with the 5930K

 

[DavieJG]

So 5820K unless you want multi-GPU.

 

[xixou]

Indeed.

 

[Gazb]

Is things like SATA Express not going to be eating up some PCI-e lanes?

Thanks for the info. I hadn't realised Intel actually started nerf'ing the CPU's in terms of PCI bandwidth. Personally I wouldn't go for an SLI setup but it's useful to know for anyone that will.

Would the limit make much on a noticeable difference to performance even if you did go for SLI or is it the kind of thing that would only register on benchmarks?

Whats the real word differences between 2 x 16 over 2 x 8 ?

 

[Orangey]

Huge difference with 4x GPU setup @ 4K:

No diff for 2x GPU setup:

It depends. If they're GPUs like Titans or 780ti etc then it will make a difference. It won't be massive, but, it's enough to put the enthusiast off. It will drop benchmark points, something critical to Epeen.

TBH the 5820k is Intel's way of making people pay more. What I mean is, the 5930k is poised to cost more than the 4930k does now, so how do you get away with it? simply stick in a duff product underneath it to prop it up.

Same as they did with the 3820. What a useless pile of rubbish that was* but hey, makes the 6 core CPU seem like it's good value.

*Whilst there wasn't really anything wrong with the 3820 it would be pretty insane to drop a nut building a rig with a £240 board in it and quad channel ram for such a measly CPU.

If you run one GPU, and can stand the fact your chip has stuff cut out then the 5820k will be a great CPU to have (even though it looks like it is going to cost what the 4930k does now and be missing lanes). The fact is though that Intel know what they are doing and they want people on the 5930k.

This +1. If you think about it, intel will be making a reasonable profit on the 5820k, especially considering the lack of amd competition at the moment, they can mark them up reasonably.

The 5930k is literally just a 5820k without some pci-e lanes lasered off. So anything extra is literally PURE profit for intel.

Can I have the crystal ball that you and Andy seem to wield so well?

Whilst it's easy to blame intel and say they are deliberately sabotaging the 5820k, by 'soldering off' lanes/cache - you have no way to prove this.

It's quite common practice that not all the CPU dies will fully work. Maybe some of the cache, or pci-e lanes do not function on some dies. Instead of throwing these away, Intel simply disables the faulty portions of the die and labels them as a lower performing part.

Whilst it may well be true that Intel sabotage them, to make lower performing parts, to prop up the price of the higher cpu models - they may just be binning CPU's.

I think it's quite childish to simply assume that all the Haswell-E dies are 100% perfect and during binning, all reached the same frequency in Mhz/Ghz at the same voltage. Of course they didn't - so the best CPU's which reached the highest frequency and had fully die functionality are used for the 5960X, and the cpu's that didn't reach the same frequency at that voltage were used for the lesser models etc.

I'd recommend reading up on CPU binning, before you make assumptions that you cannot backup with any facts.

Stop being so naive . Facts being its been done time and time before by both cpu manufacturers and gpu manufacturers, and that its great business sense for intel at the moment (but crap for us consumers hence me making such comment) during amd's competitive absence in this part of the market.

Yes there will be a certain element of defective cpu's of course, and they will get binned accordingly, but with the seemingly large demand for 5820k just from this thread alone, do you really think miracously hundreds and hundreds of thousands of 5820k's will conveniently have manufacture defects allowing perfectly only 1x16, 1x8 and 1x4 pci-e lanes? No. They will be lasering pci-e or whatever process used a large number of '5930k' chips to make the 5820k's. They would never keep up with demand otherwise. Intel modifying chips would greatly outweigh manufacture defects, affecting 'just' the pci-e lanes. Remember: the only difference between 5930k and 5820k are pci-e lanes, they both have 6 cores still.

Other than that you make one good point in your post, in that intel is propping up the market for their 5930k.

As i say, great for intel, not for us consumers. Haters gonna hate moaners gonna moan etc. we need to have a voice for whatever little its worth. I and i suppose many others wouldnt mind so much if we had our pants pulled down sometimes in situations like these with lack of competition, IF it wasnt the case all we have and are getting are incremental increases, larger prices and early superseding of products / overly frequent new sockets and platforms.

 

[MrMarvelous]

The 5820K will do me nicley. Would rather have 1 GPU and upgrade than have 2 GPU's and possibly have issues.

 

[Zeed]

MrMarvelous same here. Enough problems with TriDef as it is no point of adding crapfire with even more problems.

 

[ALXAndy]

Or you could try spending the afternoon doing some reading. Here's an example of my 'crystal ball'.



See that? that's a 5960x. It's also a 5960x with the lid removed, and one can clearly see that it has 12 cores, 4 of which have been disabled.

So basically, mate, it's a rebadged Xeon. One doesn't need a degree in common sense to realise that.

Gave crossfire another go this week, was awful. Even when fps were high enough there was still really bad stutter. Unparking cores, overclocking, underclocking. Nothing helps. Back to single GPU again now. At least I know for certain dual GPU's aren't for me

X99 + 5820K + single 20nm GPU is the way forward imho.

One also doesn't need to keep being so rude to other forum posters. Can't you just tone it down a bit Andy?

No, not really. Takes about an hour to go to Intel's site and look at all the Xeons before realising what's going on.

Enjoy your 12 core derped server CPU though dude. Maybe Intel will let you have all twelve for another bag of sand in about three years time.

You did enable Frame Pacing yes?

TBH it's only been about a month that I've been somewhat happy with Crossfire.

Huh what? Your original hostile comment wasn't even directed at me. I'm just saying you come across rude to a lot of people on here. There's no need mate. Just tone it down.

Oh and I will enjoy my Haswell -E chip when I get it. Thanks for your concern mate.

Yeah I tried everything, the solution in the end was to remove the second card Works great now. I'm really sensitive to micro stutter I think, not just crossfire but SLI as well. I won't mess with dual cards again.
