AVX instructions have very low performance
While that was mentioned in the context of Asus' non-K OC, I wonder if that applies to ASRock, and indeed, all non-K OC? If so, I'm actually relieved that I didn't get an i3, because it would have been gimped down because of that mis-feature.

We will soon see if AtenRa's prediction that i5k sales will plummet is true or not Will keep a close eye on Intel's reported desktop CPU ASPs.

Note that these are in fact BETA versions of the BIOS and there is thus a long list of issues and warnings: no IGPU, No dynamic change of CPU frequency, No C-states, No Turbo Mode, CPU temperature reading is incorrect, AVX instructions have very low performance and Windows XP ACPI not supported.

I have also said this,

I believe Intel will not have any problem to allow this only on the very expensive Z170 motherboard models.

This way only overclockers will bother to OC a Pentium or Core i3/5 and normal users will opt for a cheaper motherboard to pair it with a locked Core i5 or even Core i7.
If you need a $150-200+ motherboard to just OC a $70 CPU then for the same price most users will go for a $50 motherboard + $190-200 Core i5.

And judging by the results of this one,



I can tell you right now i would easily recommend a H110 + Core i5 6400 over Z170 + Core i3 6100 OC (for budget constrained users). Especially for gaming.

But what happens if you can OC the Core i3 6100/6300 on a H110 board ??

I will immediately recommend the H110+ Core i3 OC for low budget gaming systems over the Core i5. The only Core i5 to be recommended will be the K model for the 1% of users that will spend 300-400 for a CPU + Mobo.

And let me explain to you why Intel dont want OCable H110.

H110 + OC Core i5 6400 = Lowest margin products of each family (chipset and CPUs)

If the Core i5 6400 can reach 4.4GHz on the H110 motherboards, Z170 + Core i5 6600K sales will completely plummet.

Z170 + Core i5 6600K = Highest margin products of each Family.

In 2011 the best selling Intel CPU was the Core i5 2500K, the highest margin Core i5. In 2016 it will be the Core i5 6400, the lowest margin Core i5. It will also destroy the Core i3 sales because people will choose only two CPUs.

1. Pentium G4400 ($65) OCed to 4.4GHz + H110
2. Core i5 6400 ($190) OCed to 4.4GHz + H110

Nobody was recommending Haswell Core i3 over the Pentium G3258 or entry Core i5s in 2014/5. Same will happen in 2016 if H110 will receive an OC bios.

I mostly agree with your assessment, but I wouldn't say that "nobody" recommended the i3 over the G3258. Some people on this forum did, after some reviews came out showing the poor minimum frame-rate and stuttering issues that the G3258 had with some of the more recent modern AAA games that really wanted quad-core CPUs. Not to mention the few games that were initially released that wouldn't even start up on a dual-core.

Im one of those that did recommended the Haswell Core i3 over the Pentium. But when you can get a cheap H110 board and OC the cheapest Core i5 to 4.4GHz there is no room for the i3s.

Some impressive performance numbers by Core i7-6650U in the Surface Pro 4 performance comparison by NotebookCheck (Core m3 vs Core i5 vs Core i7). I think eDRAM is definitely improving performance in some apps/benchmarks.

- CPU





3DMark 11 Physics Score






- iGPU

Bioshock Infinite




3DMark (2013)


It provides 64-81% better performance than Core i5-6300 (HD Graphics 520) at the only game they tested, Bioshock Infinite. Considering Surface Book's dGPU is at least 20% faster than a regular Geforce GT940M, Intel is pretty close to the performance of the latter (as I expected).

Iris 540 is >2.5x as fast as HD 4400. Compared to the previous Core i7-4650U (HD 5000) powering the Surface Pro 3 we're looking at ~30% better CPU performance and 100-150% better graphics performance. Not bad Skylake.

We had our doubts on the performance of the Surface Pro 4 Core i7 configuration considering the throttling issues found on the Surface Pro 3. Luckily, we can observe no major performance issues when under high loads. The tablet is able to maintain its maximum Turbo Boost of 3.2 GHz for both cores when under Prime95 stress and Unigine Heaven stress. The integrated GPU operates at a very steady 950 MHz under similar conditions. Throttling will occur when running both Prime95 and FurMark simultaneously.

That's stupid.

Core i5 6400 on Z170 for overclocking. Recommending an H board is just plain dumb.

Yeah, it's a place where trying to shave $30 doesn't make a lot of sense. H170 would be a little less questionable if they were priced right, but given that the cheapest H170 board is the same $80 as the Asrock Pro4S, there's no reason to look elsewhere.

IMO overclocking the i5-6400 processor is the least interesting for a new gaming rig if you're wanting to OC unless your system is pretty low end. Yes you save $90 vs buying the 6600k, but even with a $200 GPU you're probably still looking at the difference being $800 vs $900. The savings aren't nothing, but given the issues you do have to question whether it's worth paying the extra for the unlocked platform. Upgrades are a different story of course. If you're already running a 2500k or similar with a 7970, <$300 for a 6400 and Z170 board with 8GB of DDR4 would be a pretty decent upgrade.

What part of "budget constrained users" did you missed ???

Not to mention the context was Z170 + Core i3 OC vs H110 + Core i5 6400.

Also, is the Core i3s default Heat-Sink enough for 4.4GHz OC ??? or do you need to spend more for an after market heat-sink ???

It's strange that NBC's sample did not throttle as much as the one shown in this video: https://www.youtube.com/watch?v=FpLLliWT5FM The sp4 i7 is known to throttle the power limit from 25w to 15w when under CPU + GPU load for ~30 seconds for the early samples. Not sure if it is fixed yet.

6th gen NUC i5 is now a bigger upgrade to i3 than the 5th gen btw.

Argument being?...

Lol I'm joking, not that stupid to ask you for arguments in your posts when we all know how you roll on this forum :awe:



I would change the H110 for a B150, they come in with better VRMs most of the time and some B150 even are identical VRM wise to the most budget Z170 some people praise here (only to suit their flawed agenda, I know, but still).

Z170+i3 is just plain dumb when you can cash in an i5 with a H110/B150 and overclocking just the same as a budget Z170 board for most of the air cooled, budget setups this very configuration applies. The RAM speeds arguments also becomes moot because with BCLK OC you can up the RAM even if the chipset artificially locks you to x21.33/x16.00 (depending on DDR3/4). BCLK OC is a win-win for everyone and I just hope they can eventually make the iGP work too (but i think this would need to change how the iGP clock setting in bios works, if it becomes another multiplier-based setting it might work just like RAM OC via BCLK).

Surprising results indeed. Also curious that it priorizes iGPU performance @ Prime95 + FurMark stress test, CPU clocks drop to half but graphics clocks are still pretty high.

Core i3-6100 + Z170 still costs less than Core i5-6400 + H110/B150 though.

I have a feeling Asrock will be the first to enable BCLK overclocking on the low-end chipsets at some point, but considering the relatively small price premium I'd still go Z170.

The question is this: Do you want to plan your build based on the assumption that overclocking of locked Skylake CPUs will be possible for all time going forward?

If the loophole gets closed by Intel at some point, you could end up with a system that is not very well composed anymore. Then what looked like a good deal when the system was bought no longer is... :\

I didn't "missed" anything. Z boards are now $80, which give you an overclockable quad core.

H boards are just plain stupid to buy right now.

EMCKNKV22

That's the promo code for 15% off on that $80 mobo. Yes, I ordered another one.

Also worth noting is the fact that 15W Core i7-6650U delivered nearly 85% the graphics performance of 65W Core i7-5775C at much lower TDP (3DMark 11 and Firestrike). I have a feeling Iris Pro 570/580 (GT4e) is going to pack some serious punch next quarter.

Like I have said before, though, the problem with Iris pro is that you have to pay a *very* high price premium to get it.

Hard to say, there's only one Skylake-U GT3e product on the market right now (as far as I know), the Core i7 version of the Surface Pro 4. ARK prices are very similar for HD 520 and Iris 540 based processors, they might not reflect reality but I don't think there's a huge premium for GT3e. These chips will likely be used in the 2016 Macbook Air lineup.

BTW it's Iris, Skylake with Iris Pro comes in Q1-2016 (BGA).

Actually the Macbook Air might be going away since it's kind of redundant with the Retina Macbook. Apple might be interested in the Skylake 4+4e though for a new Macbook Pro if it's in any kind of realistic volume.

60 bucks difference between the 6100 and 6400, 29 bucks difference between the lowest priced Z170 and the lowest priced H110. You are telling me people wont try to save 31 bucks and avoid going 2c4t in 2015 when overclockable 4c4t is just around the corner? I stay firm in my stance that you cant beat that kind of value, 6100+H110 is another matter and I find it more appropiate to compare against the other solution. A $129 CPU with a $80 motherboard will never make the same sense to me as a $189 CPU with a $51 mobo. The days of motherboards making such a huge impact in performance are long, long gone and now we just have to deal with the absurd artificial crippling Intel does to their chipsets.
