6700K or 5820K?

[BigDaveX]

According to the reviews on this site and Bit-Tech, there's a decent but not earth-shattering improvement between DDR4-2133 and 2666 or 2800 on Haswell-E; in the realms of about 5-10% depending on the situation.

Above that, performance increases are much less noticeable; in fact, it could get a little worse at higher speeds due to the much slower CAS timings.

I honestly can't imagine my 4770k needing to be upgraded in a long time.

The thing is that my thinking was, when I built the machine that after about three years I would have to start overclocking it to achieve a reasonable performance.

I originally had a 965X if I remember correctly and a couple of months or so later I saw an offer for the 990X which I could not refuse (the difference in the price of selling my 965X (I got more money for it than I paid for it) and buying the 990X was £75.

The thing is that even if I had kept the 965X I don't think I would be feeling a need to upgrade because of performance.

I have undervolted my 4770K by an offset of -0.09 volts and it is running nicely up to 3.9 GHz on all cores. I will keep it running at that and maybe go to -0.1 volts next week.

Hand on heart, the 990X is the first CPU that I have had that has not become VERY long in the tooth after five years. One of these days the system is going to turn into a rock, all things come to an end.

So in theory on this board you can run 8x/8x/PCIe3 off/8x/PCIe5 off and have 2x GPUs (in slots 1 and 2), a PCIe 3.0 x4 M2 SSD installed(disables slot 3), and still use PCIe slot 4 for a dedicated sound card? That's the setup I'm looking for I think.

That's how I am reading it as well. My recommendation is to verify with the manufacturer before you go out and purchase any board that has such specific requirements like you noted. For example, in theory a Black Magic 4K capture card should work in PCIe 4x, 8x or 16x, but in practice, there is a compatibility issue with certain boards/bioses in detecting it.

Are you looking to jump to the PCIe SSD this year? I mean your system is still very potent and you do not have 980Ti SLI which is why I am curious why you wouldn't wait until SK-E to do a full overhaul of your GPUs + CPU + PCIe SSD? Also, PCIe 3.0 x8 SSDs are starting to come out which makes me think that in 12 months we could see way faster PCIe 3.0 SSDs.

Another benefit to waiting a bit is DDR4-3200-3400 memory prices should drop which means removing the bottleneck for Skylake-E.

Just curious as to your thought process is. I personally think based on your usage patterns (i.e., primarily a gamer, want to maximize perf/watt) and that you upgrade fairly often (2-3 years), I think the i7-6700K would be better for you.

I don't need new GPUs. I could use the USB 3.1 and do want the faster PCIe SSD option. I'm thermal limited with my mATX motherboard because of how tightly packed it is. I want to remove that so I can spread my GPUs out better and the extra features and a faster CPU are a bonus. I'm also thinking a 6700k would be better for me because I don't do anything that a 6c/12t cpu is a real benefit, plus the thermals are a bit better on 6700k. I've been going back and forth over the past week thinking of what I want to do. Now that I have a pretty good idea on what I can do with both platforms I can make a better informed decision. I actually want to repurpose my 3570k for a relative to use.

A bit off-topic, cmdrdredd, but how many millivolts did you bump up your MSI cards for 1480/8000? I'm at 1470/7500, and I had to move the slider from 0 to 20 mV. Essentially, I have the same cards as you do.

 

[tential]

Are we expecting Skylake-E next? Will that be a "Fun" upgrade for my 4770k? Not that I need to... but I mean.... I might as well see what the next step up is on the HEDT Platform lol.

 

[myocardia]

Are we expecting Skylake-E next?

No, Broadwell-E is supposed to be released next, roughly Q1 2016, with Skylake-E coming ~12 months later.

 

[soccerballtux]

Huh? I thought DX12 was meant to put less strain on the CPU, not more?

I disagree with him and agree with you

so, why is it slower, and did they cook that in? I feel ... unimpressed with this part...given the L4 cache.

 

[CakeMonster]

I'd be willing to pay a premium for the E platform if it the new architecture was available sooner. With this the current kind of delay however, no way.

They did it at stock but it was more stable when I bumped voltage. I'll check for you when I get home and PM you.

What are we expecting from the new hedt boards/processors over haswell? I was going to get skylake-e for an upgrade over 4770k(fun) to have a hexacore cheap.

I hope ddr4 memory is cheap then I'll have a lot of fun on a next gen gaming rig with node shrinked card+cpu.

Heh, will probably be a complete new build and let me have 2 rigs in my place for gaming with friends and roommates lol.

 

[Erik Jan]

New user here with same dilemma... Buying new system now (so I won't wait too long for 'better' things next year ).
I'm not a gamer but want a system that I can use for 3-4 years and I'd like a bit high-end. I do use LightRoom (picture editing). OC... nah... not really at the top of my list as well.
Will choose i7 (don't care too much if that is overkill now; I just don't want regrets later). I think I want an NVME SSD (max SSD speed I can get now). I also want 16Gb (min - don't care too much about DDR4 or DDR3) and think I'll go for an NVidia GTX970. The rest is more or less open.
Now power supply and other stuff is something I can figure out from here myself but I'm also stuck between an 5820/X99 and the 6700/Z170 choice.
With my 'requirements' in mind; what would you think I'd do best?

(A small (?) other restriction I might have if space so maybe I want a uATX size MB but that's less relevant for now).

Any suggestions that could help me would be very much appreciated! :biggrin:

If you don't overclock the 6700k has a higher clock speed and will do better at anything that doesn't use multiple cores well. Lightroom as I understand it isn't very good at using extra cores.

 

[ioni]

I don't think it makes sense to get a 5820k if you aren't going to OC. I've never heard of uATX but maybe you mean mATX? I was all decided on building a 5820k build and also want mATX but the mobo prices for mATX 2011-v3 scared me off and I'm just going to wait for the 6700k now.

 

[MrTeal]

I don't think it makes sense to get a 5280k if you aren't going to OC. I've never heard of uATX but maybe you mean mATX? I was all decided on building a 5820k build and also want mATX but the mobo prices for mATX 2011-v3 scared me off and I'm just going to wait for the 6700k now.

Everyone abbreviates microATX as mATX, but in most fields the proper SI prefix of m is used for milli and u (or µ) for micro.

 

[Erik Jan]

Yeah sorry.. I did mean the 'one tick' smaller ATX board: my space is somewhat limited and I'll never need any additional bays in my system other than the SSD, a data HD (Seagate Black probably; 3TB) and the mentioned GTX970 (I'll for sure will never add an additional video board so cooling requirements would be limited and my case can thus remain small).
Oh... I forgot; of course I'd like USB3.1 (but that's not a big requirement).

So I understand the Skylake might be better choice then?

 

[ioni]

I almost mentioned 3.1 in earlier, but since you didn't, I didn't bring it up, but 2011-v3 mobos with 3.1 are also pretty pricey. I think the only mATX mobos with 3.1 I found the other day when I was looking to build were in the $280-$300 range. Even the ATX ones start in the mid $200s if you want 3.1.

I still think an OCd 5820k would be a better system, but I'm not sure it's worth the price premium. But again, if you aren't going to OC, Skylake is definitely the better choice.

 

[Erik Jan]

I see 4 mATX 1151 (SkyLake) MoBo's; it'll be the "ASUS Maximus VIII Gene"; if I'd go to the 2011-3 I also find 4 Mobo's (but no one with USB 3.1).
All these are between 100 and 200 (Euro) more or less...
What if I'd stick to my requirements (6700 or 5820) but release any price restrictions...? Can I buy a better 5820/X99 system for my purposes?
I think not (but remain open to suggestions).

 

[know of fence]

It's amazing that Intel can get away with selling a piece of silicon half the size for the same price, without throwing in some extra cores or bumping up the i3 to 4 cores.
In the past they could point to greater performance or smaller consumption, but performance only slightly changed while both idle an TDP went up a bit.
Though not according to AT power consumption testing, which as tradition demands is performed with dowsing rods.
Maybe a 4 core CPU is all a client will ever going to need, but intel will have to do something radical to their rather stale product line-up sooner or later. The low end will become Atom quad cores, core i3 will go away, or will be simply downclocked i5s and we get a core i9 perhaps.... Naa, that can't be right more cores do require a beefy platform as well. Though perhaps the bandwidth of later DDR4 will suffice to feed more than 4 cores.

1. i7-6700K for your description is better.
2. If you are not a gamer, 750/750Ti/950/270/270X is a better bet than a 970. Why overspend extra as it will provide no benefit for your usage?

 

[tenks]

I think I decided what I'm going to do. Skylake-E is too far away, and Haswell-E is long in tooth and 2 core generations behind. Going go with broadwell-e, hoping the Q1 is an immediate release in Jan.


Man HEDT pisses me off!

 

[alcoholbob]

Good luck trying to cool those CPUs. Haswell E is 140W. Broadwell E is listed at 160W and Skylake E up to 165W.

Chips keep getting hotter and hotter.

silly pool verdict:

most 4core users never had 6/8 cores cpu. And they can give their ignorant vote to the pool.

they re totally uninformed, their only informations are from online benchmaks. They vote only what they know (cheap stuff). Pool is biased by cheap users.

if u make a new Poll in which only Users with BOTH 4core and 6core cpus can vote, it will be way more reliable

I find it extremely hard to believe people like you actually exist. Aside from your terrible sentence structure, your posts are insulting and without merit.

People don't need to own a specific CPU to know it isn't for them. That's why they didn't buy it in the first place. Posters on anandtech are pretty well I formed by and large. They research products that fit their needs and for most, a 6 or 8 core CPU doesn't fit their needs for the price demand. You don't have to be rich it just has to fit your needs.

It's pretty simple, if you don't do rendering and photo/video work then you are probably wasting that 6core CPU.
