Intel Broadwell Thread

[cytg111]

Where the hell is Broadwell-E at? Was it not supposed to be here by now?
Need to witness som some overclocked 10-core domination here..

.. The addition we noticed is that the X99 FTW K removes the PCI-e 3.0 x4 slot in place of a M.2 slot which can be used to house a fast SSD..

..There’s also switches to disable PCI-Express slots which come in handy when you want to put use of those extra PCI-e lanes elsewhere..

 

[Aristotelian]

PCI-e 3.0 x4 slots can also be used to house "fast SSDs" no? And by 'fast' I understand that to mean 'the fastest'. That's why I want a high end ATX-e board with PLX chips to ensure that there's plenty of PCI-e lane space for multiple SSDs on top of two GPUs in sli/crossfire.

You can use the lanes for anything. That's also why newer boards sports M.2/U.2 slots.

 

[Aristotelian]

If PCI-e ssds are faster than other ssd solutions, from a performance perspective it looks like a bad thing to remove PCI-e slots in order to provide for the other storage solutions. I don't mean to come across as elitist here because I'm not, but I thought the "FTW" line of motherboards represent the offering to premium/high end market.

On the Broadwell-E itself, I think I tried asking this question earlier - apparently the 'memory controller' within the chip itself is the salient factor in Memory Speeds, and apparently this has been upgraded compared with Haswell-E. Would any of you know if this is the case? It would allow us to couple faster DDR4 with Broadwell-E which could, in some circumstances, provide added benefits.

 

[ShintaiDK]

M.2/U.2 SSD can be connected with up to PCIe 3.0 x4. That is quite fast.

 

[Sweepr]

Maintenance Bot @ Overclock.net got early access to the Core i7-6850K and ran some benchmarks (clock-per-clock comparison with Haswell-E):

Broadwell-E is thinner:

www.overclock.net/t/1599068/6850k-vs-5820k

~10% faster @ Cinebench R15 MT.

[Shivansps]

Pentium D? Fail

 

[Aristotelian]

Thanks Sweepr. Clock for clock it's faster than Haswell-E. That poster didn't push a max overclock (he's using an intel air cooler from what I can tell) and boy, I'd love to see some memory overclocking too. I can't wait to push the 10 core under custom water and see how far I can go. Fingers crossed for the chip lottery.

Aristotelian: From what I read Broadwell E's shrink to 14nm includes improved memory management with the controller having DDR4-2400 capability vs DDR4-2133 capability in Haswell E.

Obviously DDR4 ram can be overclocked but this spec improvement alone seems to indicate support for much higher ram speeds.

I would hope that clock for clock Broadwell E is faster than Haswell E, the question is how much more.

Finally, it sounds like you are building a whole new rig. Do you have the custom cooling ready to go?

 

[LTC8K6]

Overall, that comparison is pretty encouraging for BW-E.

you're comparing chips with IGP's. Broadwell-C is not Broadwell-E

same architecture....

 

[ShintaiDK]

Different uncore.

 

[Sweepr]

Indeed. Broadwell-K with eDRAM is (only) ~5% faster than Haswell in this benchmark.

I have read about the improved memory controller too because there have been quite a number of posts complaining about memory speeds with Haswell-E, especially with boards like the ASUS X99-e WS, where it was clarified that the memory speed (overclocking) is partly dependent on the property within the chip itself. From benchmarks I have seen on this forum (e.g., does RAM speed matter? type threads) it seems that over specific levels (e.g., 3000), the increase in DDR4 ram speed will eventually be offset by the increased latency at those high speeds and - furthermore - that the increase in RAM speed brings a negligible performance boost. So around the time when I build for Broadwell-E I'll probably create a thread in the memory subforum asking for help finding the blisteringly quick 3000 or so speed ram.

At this stage - for someone like me about to build an entirely new rig, I'm drooling and waiting for Broadwell-E reviews which I hope come soon. I know there are probably people reading this who are under NDA, but I wonder if it violates an NDA to even hint at when the NDA period finishes?

[Off-topic disclaimer] Yeah - I am building a whole new rig man, completely watercooled - and thanks for your contributions in the other sub-forum in that 'ultimate water cooling setup' thread. I am working with one of Europe's best modders to build a bit of an artistic thing, but there'll be 3x480mm radiators (EK), 16 GT 1850 rpms (only one rad can fit 8 in push/pull in the Core X9). The radiators are really thick man and even in that case I'd have clearance issues if I did all the radiators in push pull fan setups.[/end]

So the Broadwell-E will go under a fairly ambitious watercooling setup and I'll look to people here (and elsewhere) for tips on pushing it to its most stable limit! As Adamk47 would say - Broadwell-E and Pascal/Polaris coming soon is going to put a major dent in my wallet. And my wife would have my head if I bought the new Dell OLED at the same time. Luckily, OLEDs seem to be coming out around Christmas, so I can gift one to myself due to a negotiated marriage clause And I'll stick with the Dell U2711 until then (lol!)

 

[tenks]

same architecture....

Yea, gotta love these statements. Not even going to waste my time on this one.




Anyway Aristotelian, I'm with you! I'm building a whole new rig myself Broadwell-E & Polaris/Pascal depending on the price/performance shakes out. I'm really excited.

Not so fast.. Seen the new 65w Skylake quad's?

http://www.anandtech.com/show/10281...65w-edram?_ga=1.239515594.81743884.1447038657

 

[Head1985]

His 5820K results are very low.And R15 is very random.
old ivy bridge at 4.2Ghz have 1121points.
And from another site they tested 5820K at 4.2ghz and results are 1273points.
So most likely 3% IPC just like haswell vs broadwell in CB.

 

[guskline]

Aristotelian, yes it violates NDA so we have to wait. I played around some with DDR4 clock speed on my 5960x but settled in on 2133 at 4.4 so I could run benchies forever without errors. I tweeked my bios to raise the mem cache speed. I'm extremely happy with my Haswell E and I'm sure when you put together that 10 core monster like AdamK47 you also will be happy.

Good luck.

Can you say iMac???

Again though, seems like a great product limited to a small (most likely expensive), segment of the market.

Intel really reminds me of General Motors is the US in the 80s I think it was. Well, Intel's products are better, but there is just such a dizzying array of models the average or even well-informed consumer can barely figure out what is what.

 

[Qwertilot]

It is a bit baffling At least they're not really selling their CPUs direct to people....
