Intel Skylake / Kaby Lake

[Dufus]

@inf64 I concur and get a little over 3900 ST at 4.25GHz with an i7-4700MQ.

So Core i5 Skylake-S was 15.8% faster in ST and 17.7% faster in MT despite Core i7 Haswell's extra cache. Impressive.

Sweepr, you appear to be doing it again. Do you know for sure if the i5-6600K wasn't overclocked?

Take the i5-6400T, scores 2871 ST with what looks like 4GB RAM (single channel). If I run my dual core Haswell, which has less cache all round, at 2.8GHz and single channel 4GB RAM it scores 2655 ST which means ~8% improvement. Lots of if's not to mention memory bandwidth effects.

It just throttles until it reach 130C. But ye, you can run it without heatsink and not worry if the pump fails

I dont even think its possible to reach the shutdown temp, unless you disable all security features or use a blowtorch on it.

There is a big i7-6700k and i5-6600k (ES) test in PCGH magazine which I received today. As of the editorial deadline Intel didn't sample them with official informations and therefore no NDA was signed.

CPU performance is nothing special to be honest, in most games ~5% faster than Haswell. Battlefield 4 runs slower, possibly a game bug. x264 on i7-6700k 13-14% faster than i7-4790k. iGPU results are mixed with 1-2 driver issues (WoW crashed, Skyrim some odd slowdowns) but I think there is potential, similar to Ivy Bridge when it launched. It is obvious this is an overhauled Genx. 24 bit/32 bit IOPS in AIDA64 improved from 46 GIOPS to 153 GIOPS.

Single Precision computing power as expected not much difference 414 Gflops vs 459 Gflops measured from Aida64 (20% more EUs but also 100 Mhz slower GPU clock). Nevertheless there are big improvements in some games they did test, clearly a Genx overhaul.

BCLK will be possible on non-K CPUs and another good thing, CPU load temperature lower than Haswell.

Guess it depends on how much clearance you need

With a 6700K I need to buy a cooler. Its been a long time since.

Thinking on this:

http://www.zalman.com/global/product/Product_Read.php?Idx=468

Since it needs to fit in ITX case too. And it looks very good, good cooling, very silent.

Unless, anyone else got better idea?

Two heatpipes won't carry much heat, despite the clever layout. Look over at the Noctua stuff. They have some low-profile heatsinks. Start with their website.

An educated guess. From previous leaks Skylake-S does really well @ Geekbench. Most leaks are from stock clocked OEM systems.

Thats where I started. But their coolers seem to have trouble at 95W. And most are 65W in the area I want.

In reality I could settle with a standard boxed 95W intel cooler. But they are removed from K models with Skylake.

Going through their list. Very nice link!

Also no tower coolers. And I guess no taller than 100mm. Plus restrictions to how much space they take to the sides.

Not sure I trust Geekbench results all that much. 6700k scores are all over the map for it: https://browser.primatelabs.com/geekbench3/search?utf8=✓&q=6700k

 

[Dufus]

I think that goes for a number of benches, really need to confirm clocks and memory.

The 6400T benches http://browser.primatelabs.com/geekbench3/search?q=i5-6400T

 

[ehume]

I tested a tandem tower Noctua. It was 110mm tall. I think for low profile heatsinks, you are stuck at blow-down. But when you look at comparative studies, make sure they are running as hot as possible. Some heatsinks keep up as long as the temps are low. The others tend to shine only at hot temps. That's why counting heatpipes is a good rough guide to cooling capacity.

As for standard Intel heatsinks. Generally people have lots of them floating around, even in Denmark.

 

[inf64]

Yeah I would just dismiss GB3 for the time being. No accurate reports on clocks (almost all results, mine included say stock CPU clock), too much variations even between same gen of chips, very cache sensitive etc.

@ Shintai

Do you think NH-L9i could cool 6700K @ stock? That cooler got some good reviews albeit tested on SB gen of chips.

Thanks for sharing mikk. So BCLK overclocking is back, lower temps, improved IPC, new graphics architecture. Fun times ahead. Next week can't come soon enough.

I would say no. I looked at it as well, and my conclusion is its not up to it or barely.

Seems it just cant transfer heat well enough.(Without a large die).

[ComputerGuy2006]

The only remark I made about your post was to ask what your current specs are.

You seem like a very paranoid individual.

Nothing to do with being paranoid, I just do not find you very intelligent, and you have made condescending remarks in the past. So I did not want your feedback. I think your attitude in this thread just confirmed my suspicions.

Cooler with a board?

I worry if they will actually fit. Plus the issue getting cables around them and such.

This for example doesnt look like something I want.

 

[tdslam720]

Yeah probably. It's odd that GB3 is so cache sensitive, 33% more L3 gives you 10% more performance . Skylake probably has faster caches too which could explain the rather large boost we see with 6600K.

It's the cache. Look up 5820k and you get similar scores. OCed scores closer to 6000 even.

Silverstone AR06 then, ill try to find a comparison vs the Zalman

Hope you are not basing bclk on that FUBAR 6400T cpuz pic that was posted a few days ago?

 

[Wreckem]

If the EVGA Z170 Stinger got a M.2 slot on the back for SSD. (There is a M.2 riser on the front for Wifi next to the battery). Then its no competition, I will get the EVGA Z170 Stinger.

However if it doesnt, then I have no idea yet what I will do. Either another mobo with the features I wish, or a compromise.

Every Z170 mitx board will have a m.2 located somewhere on it. Any particular reason you want an EVGA Motherboard? Their previous Z series itx offerings had the least features and not so great BIOS's.

Perhaps you could try your old cooler temporarily, and if it works, just buy an Intel cooler from ebay or the like.

It was based from the PCGH test. But I didn't read all the text properly, they wrote this is possible only for K-models. This info comes from Asus. PCGH tested only K-models, they couldn't verify this.

When I have to buy one, I can just as well go the full length.

I like the build and features. And I had no issues or wierd things.
