When I set out to do this initial look at Intels new X99 CPU's I wanted it to be all about how efficient the CPU is and how does it compare to the last gen. I also wanted to know how far it would Overclock on good Air cooling such as the Megahelms with two fans attached and basic custom water cooling XSPC dual rad (240mm) with raystorm cpu block setup.

For once I picked the least overclockable chips I tested from system OEM stock so all my results should be easy to replicate by all customers. Most customers want cool operating hardware so if I had to use voltages where temps go above 80C I backed off.

I ran the memory speed at DDR2400 C10 for all my initial ambient overclocking testing.

For stability testing I used Intel XTU and Prime 95 ( Not normally a choice of mine but guys on here love it!!) I ran both for one hour each.

My motherboard of choice was my ASUS Rampage V Extreme which performed flawlessly throughout with some insane DDR4 overclocking possible.

First I tested the 5960X 8c 16t CPU on Air cooling 3.9-4.0 ghz was possible with 1.1v and uncore at 3.5. For this I used Cache volts at 1.1 vccin 1.9. During loading temps where in the mid to late 70's.

The 5960x definitively benefited from water cooling with 4.2-4.3ghz being possible on water with 3.5 uncore. The volts I could use on water where 1.2 core, 1.2 cache with temps topping out at 78C.

I am sure with a quad rad on CPU even more mhz will be possible. At 4.3 this chip is a true power house.

Next I looked at the 5930K 6C 12T on good air I got this one to 4.0-4.1ghz with 1.15v Uncore was at 3.5ghz with the same volts. Temps on load peaked at 78C.

Like the X the K benefited from water cooling. I managed 4.4ghz with this sample at 1.225v with uncore at 3.5ghz on the same volts. Temps peaked at 79C.

Finally I looked at the cut down 5820K which offers 6C 12T just like the 5930K but has less PCI X lanes 28 to be precise. This means its only really suited to single GPU setups. The 5820K I expected to clock the best of all as it does have these cut down features.

This was not to be on Air the 5820K reached 4ghz at 1.125v with 3.5ghz Uncore temps around 77 C peak and on water it reached 4.2 at 1.215v with 3.5ghz uncore.Temps where again in the late 70's C.

My initial conclusion about how overclockable these chips are is they are very similar to there X79 counterparts volts for volt. But they get warm much quicker which is hardly surprising given there DDR4 onboard memory controller massive on board Cache and extra PCI Ex lanes. End users need the best cooling they can to get the most from this silicon.

After testing what ambient clocking was possible I then tested the 5930K and 5960X clock for clock performance at DDR4 2400 and DDR4 3000 against the 4930K at DDR 2400. For all these tests I used GSKILL highly overclockable and tunable 3000mhz kit. I used several benches including 3D mark, 3D mark 11, Heaven, Aida and Cinebench. Below you can see the results.



I have shown screenshot from aida further down the page so you guys can see detailed scores of how DDR4 compares to DDR3.

AIDA 4930K


AIDA 5930K DDR2400


AIDA 5930K DDR4 3000


AIDA 5960X DDR4 2400


In conclusion X99 has a lot to offer. Its DDR4 bandwidth is top notch and will only improve as DDR4 matures. As is its clock for clock performance. This translates into great speed on rendering tasks such as Cinebench and I am sure all Photo editing / sound editing type applications the same. The 8C 16t 5960X ragging through this stuff faster than any desktop part before.

I also saw excellent physics benching scores so games relying on this type of compute power will gain from X99 even if only using a single GPU.

X99 comes into its own with multi GPU setups with not only massive bandwidth but also many PCI X lanes to use.

Some games will undoubtedly get a boost from X99 but not all. Haswell on Z97 for many will be enough with single GPU but this is enthusiast level so I expect early adopters to be those gamers with multi GPU setups or professional users with a need for high and efficient core count. For these two groups X99 is great and does offer real benefits.

For me its the best benching platform so far such fun tuning GSKILL DDR4 and the potential for massive scoring. 80K plus Vantage CPU test yes please ;)!!! if your a bencher X99 is also a must.

Still get the write bug in AIDA. I think people planning on using H100 and other AIO solutions need to be very wary of PROCHOT.


Nice testing dude and great job getting on the bot so quickly. I'm sure you'll be breaking 30k in the next runs :p
 
Thanks Ian.

What I'd also be interested in is a comparison of single threaded performance on Cinebench R15 using:

3930k at 4.5GHz+, 4930k at 4.5Ghz+, 5930k/5960x at 4GHz+

My suspicion is the Haswell-Es won't overclock well beyond 4-4.2 GHz without watercooling and even then unlikely to reach the heights SB-E and Ivy-E saw. From that perspective it'll be easier to gauge what most users would get out of these in the average gaming scenarios (1-2 core useage).

Also be good to see your clocks for the different CPUs in the table.
 
My hope is that these chips do well in maintianing high/higher minimum frame rates when gaming regardless of how well they clock.
The rest of the time, I'm mainly running VM's and stuff which I'm sure will hardly cause these cpu's to break a sweat.
The IPC improvements seem nice.

Would the memory overclocking potential you speak of make much of a difference when editing and rendering some gaming footage?

8 Pack thanks finaly someone that knows what to do with them ddr4s. I just dont get the point of going for 3000mhz when you have CL of 16 :D

damn that 5820K looks good. I could run that on 4.5 with my external radiator water :)
 
8Pack thanks for your time and effort in putting these results together. There are still a few area that I want to clear up but that will come in due course. Good stuff.
 
The 4930k has slightly lower cache and suffers from the ddr3-2400 bug (slow write speed) so no improvements in IPC.
All results are about right for the slight increases in ddr4, and larger cache.
 
This was tested on air and 240 rad, right?
I have 1080 rad ( 3 x EK PE 360s) on push only, for cpu - most likely 5820k and 2 gpu's - 780s ( possible change to single Titan black or 980).
In my current setup everything runs on very low temps.
That'd with insane amount of sub 1k rpm fans of course :-)
8Pack, how do you think cooling like mine would change the peek temps on 5820k?
Would it be possible to get to 4.5k and safe temps?
 
The different speeds u can see in teh initial write up are what overclocking you can expect from a bad chip. I tested our lowest clocking system stock in each category. So 5960X you can expect 4g air 4.2 water for example.

I then did comparison of the big two vs 4930K at 4ghz. All results in the table are at 4g.

Yes reviewers no clue with DDR4. With DDR4 TWCL is a more important setting than TCL when trying to gain timing related performance gains.

I am not sure 4.5ghz with that chip. My test sample did not do well but as I said I picked bad for a reason so you guys could all attain. Temps if your clocking to limit no better as you will add extra volts to eek out more mhz. I think all chips on your cooling will do 4.4 for sure.

With these chips high cache is important also for perf so one cache multi is like 50mhz in many applications.
 
Thanks Ian.

Not much point in going single thread as users in the market for this type of chip will want all guns blazing!! My best 5960X can do 4.8 on dual rad cooler so is certainly close to my best Ivy E and beats it in benches hands down. Thats 4.8 with 4.1 cache and 3000mhz DDR4 CL11-14-15-15 1T with TWCL9. Its a silicon lottery as always. The purpose of this is to show clock for clock improvements and what everyone can get out of a chip even on basic water or air.
 
looking at these results im getting a little bit hesitant to sell up my i7 4790k that does 4.9ghz 24/7 easily...
i can only see getting this for e-peen rights lol and benching synthetic tests

for gamers this is a complete waste of time and expense.

hmmm might just hold off getting one until next year when broadwell/skylake hits.

In Cinebench not so much difference but it all depends on application. Great for physics for sure.
 
How much ram have you had a play with?? DDR4 of course!! For those that like to OC and tweak, is it worth going for the faster stuff or maybe stick with say the gskill 2666 4x4 and what could be achieved, raw mhz and best timings at 2666, with increased volts??

What would you say the 5960 clocks like on water, average??
By the way, some nice scores there with the 5960 on the Bot ;)

I tried all IC. The best at the moment for tuning and clocking are Hynix for sure. The vendors are binning hard so its likely the top speed binned kits will also tune well. The kit I am using to bench with is GSKILL 3000mhz and that tunes to 3150 11-14-15-15 1T with TWCL at 9. TWCL affects perf more the TCL in this memory. I can go C8 2750+ or C12 3200+. I have several other sticks to review and test. Corsair 280omhz 16gig kit, Avexir 2133 Value stiff to see if its a bargain!!! and soon also Kingston 3200mhz Kit. As usual I expect GSKILL to be performance king for high end.

5960 on good water 4.4+ average. Silicon lottery as always. These days you need good uncore and IMC too not just raw CPU speed.

Good info, thx ;) so are we looking at the dom plats and Gskill for the hynix chips??
