Skylake DDR3L/DDR4 review: 20 memory kits tested

https://us.hardware.info/reviews/6705/skylake-ddr3lddr4-review-20-memory-kits-tested


Golem tests the Core i7-6820HK, Intel's overclockable notebook CPU. They got 4.0 GHz + DDR4-2666 stable and reduced the power limit to 60W. Performance increased up to 25% (7-Zip).

Core i7-6820HK brings CPU overclocking to notebook

With 4 GHz and the Core DDR4-2666 i7-6820HK achieved a performance increase of up to 25 percent, and that the real pack of 7-Zip. We compress 10 GB of mixed files via LZMA2 algorithm with 12 threads, which helps in addition to the increase in CPU frequency, especially the higher memory clock. Instead in around 17 minutes, the packing process runs through in just under 14 minutes. A lower scale shows the Cinebench R15, which is growing on all cores at 16 percent and the single-threaded test yet to +12 percent.

The x264 benchmark benefited in the first pass, surprisingly little over the second, we measure +22 percent and +19 percent. A look at the log files showing the reason: By nature of Core i7-6820HK requires only 40 watts of power package, with overclocking he runs into limit of 60 watts and reduces the clock occasionally to 3.85 GHz. Instead 74 watts for the notebook at maximum brightness, we measured 109 watts, which seems plausible.

In games, the overclocking pays: The Elder Scrolls Online is CPU limited in cities, as medium-sized example we hergenommen Velynhafen. In 1080p with maximum details the frame rate from 34 to 41 fps rises - quite an appreciable difference.

Thanks to clockspeed, sure. Put the 5960x @ 4.0 GHz and it's a different story.

The 6700k overclocks too, buddy. Put the 6700k at 4.6Ghz and it still crushes the 5960X.

I have both and both chips are pretty good clocking samples. If you think the 6700K crushes the 5960X at anything you're sorely mistaken.

Ummm why would that be the case, when the 5960x wins some gaming benchmarks handily with a 500 MHz clockspeed deficit vs. Skylake quad + HT?

There you have it.

I wonder if a skaylake 6 core would be any better at gaming than a 4 core kabylake X. They are both using the HEDT platform, right? Hopefully Zen puts some pressure on Intel's pricing. An 8 core Skylake for less than a kidney would be pretty cool.

Well, I would say yes, but my reasoning is along these lines. I'm ok with giving up a little single thread performance to gain a substantial amount of multi-thread performance, I'm also ok with giving up a little multi-thread performance to gain substantial single thread performance. I'm basically looking for the best "blend" I can get at the time for whatever amount of money I'm willing to spend. It's this reason I stated in another thread after getting my 6700K that I wished I had bought two 6700Ks at the time, one to replace my 3930K. Keep in mind my 3930K clocks up pretty damn well too, 4.6 daily and can push up to 5.1 if I want. The 6700K is a quad core that is finally close enough in multi-thread that I'd prefer having the small loss at that and take the huge gain it has in single thread (plus you know, more modern platform benefits). I had the Asus Arctic Camo White Sabertooth in my hand too, and thought "Nah...no reason to upgrade right now" and put it back. Wish I hadn't now. Don't get me wrong, the 3930K still goes above and beyond what I need it to do, my son never has any framerate complaints to speak of, if anything the SLI 780s are where his bottleneck probably is in most games.

 

[jpiniero]

I'm assuming that Skylake-X will (over)clock well too, although not as high as Kaby-X. They did cut the L3 size for a reason.

 

[moonbogg]

Hmm. I wonder if I ignored the upgrade itch, how long it would actually take before the 3930k started running things slow and crappy. God it would probably take 8 more years.

I think platform enhancements are going to become the most compelling reason to upgrade to be honest. I'm intrigued by some of the platform enhancements coming with KabyLake and I hope Skylake X has access to them as well (I believe it will).

That 3930K probably has a ton of life left in it, esp. at 4.6GHz. :thumbsup:

Well some of the benchmarks here make me feel happy I went with Skylake over Haswell. I was so torn as I already had ample DDR 3 ram so the cost of upgrading to Haswell was significantly lower. Everywhere I saw the performance difference was considered negligible. In the end I justified the added cost for the better platform and I am glad I did.

Of course you made the right choice. Skylake is a faster chip than a comparable Haswell, had there been drastic price slashing to clearance the remaining Haswell chips a person could maybe argue otherwise, but not at normal pricing. It's not even like you would have "saved" money by staying with DDR3, you simply paid for DDR4 now rather than deferring the cost to the next build which would have almost certainly required DDR4, assuming you reuse it then.

Yes that is a good point and I was able to sell the DDR 3 ram so there is always that element which reduces the cost.

Having a Microcenter nearby, I have always gotten my CPUs from them, as they nearly always have the best regular prices, along with shorter term deal prices. There actually were some nice discounted deals on Haswell i7 CPUs, which I have not seen replicated so far with Skylake CPUs. For example, I got my i7-4770k CPU for $200. And my i7-4970k CPU for $280, but with free nice quality Z97 board. I've watched Skylake i7 CPU prices, and haven't seen anything close to those deals. Also for some reason, since introduction Microcenter has had the regular Skylake i7 at a higher price point compared to the prior Haswell and earlier i7s. Maybe Microcenter couldn't cut as good a deal with Intel this time around? In my experience, Skylake has been a bit of a disappointment in terms of cost, considering CPU cost, lack of deals found in prior gens, and cost of new gen ram required. At least DDR4 has gone down quite a bit in price from introduction, so having to buy new ram for Skylake is less painful.

 

[frozentundra123456]

Yea, microcenter had some great deals on 4790k, not so much on skylake. Maybe after a few more months. The skylake prices are even worse since the k models come without a cooler, so you have to buy an aftermarket one even if you dont overclock.

Moonbogg; with your rig, you're still up with the "big dogs" or is that CATS?:thumbsup:

The 6700k clocks higher. It has higher IPC than the 5960X.

In the vast majority of games, the 6700k is the clear winner.

Today maybe, but what about 4 years from now?

I would argue both are "good enough" for today and the 5960X has more legs in the future.

 

[frozentundra123456]

And it costs 3x as much and requires a more expensive motherboard. Problem with 5960x is that it is a generation behind and I think you are less likely to get a good overclock than you are with Skylake quad.

Actually, I think the closest competiton now is between 6700k and hex core HEDT.

 

[YBS1]

The 6700k clocks higher.

Really? How high does your 6700 clock?

 

[Dave2150]

In 4 years time, I'll be using a newer and faster CPU, with 3D Xpoint etc, so this consideration is moot for me.

I've had my 6700k for almost a year already, I tend to upgrade CPU/Motherboard every 4-5 years or so.

 

[Dave2150]

Really? How high does your 6700 clock?

4.7Ghz at 1.3V on air. On water it's capable of more, though I don't require additional performance at the moment.

What can your 5960X clock to on air?

 

[YBS1]

Why would anyone want to run such a processor on air? lol Point still stands, most modern processors are topping out a little south of 5GHz without sub ambient cooling. Don't act like Skylake clocks to the moon and the 5960X is stuck at a TDP limited 3GHz.

 

[frozentundra123456]

Dont think anybody said that. Problem is (thanks intel) HEDT has inherently lower ipc because it is a generation behind, and without heroic cooling measures, I think 8 cores are going to overclock less as well. I just dont see the point of 5960x unless you need the cores for other purposes. For the extra 700.00 or so the 5960x costs, one could do a complete upgrade in 3 or 4 years when the quad is (hypothetically) not enough cores.
