Just noticed that finally some Skylake CPUs are available http://www.ncix.com/article/intel_athexa.htm

Wondering if anyone has any numbers about Rosetta performance - I'm specifically interested to see how performance per watt might improve. Hoping this new architecture + 14nm process node will mean I can stuff more CPUs into my crunching farm without exceeding the maximum noise and heat levels that my wife will put up with :P

The reviews I've seen have said it's another iterative update - nothing ground-breaking, but consistent improvements at around 5-6% over Haswell and slightly lower power consumption too (in part due to DDR4). They might overclock a lot better than Haswell/Ivy Bridge did though.

I think the previous gen Broadwell chips with Iris Pro graphics are interesting - I'd like to see how they do on Rosetta because of the EDRAM L4 cache.

Also, the Haswell generation (22nm) i7-5820k is a comparative bargain now at £250 for 6 cores so I'd go for that if I were in the market at the moment.

apparently the big improvements seemed to be in the on chip graphics

http://www.tomshardware.com/reviews/skylake-intel-core-i7-6700k-core-i5-6600k,4252-10.html

however gpu based computation i.e. opencl didn't seem to have made too much a difference

http://techreport.com/review/28751/intel-core-i7-6700k-skylake-processor-reviewed/11

the core cpu computations performance seemed more or less comparable to the haswells

it would appear that the skylakes would probably perform similar to haswells (e.g.i7 4790k) running rosetta, possibly marginal improvements

Unless the developers provide new binaries that actually utilize some newer instruction sets, this is pretty much irrelevant for crunching.

Maybe if you overclock the 6700k, you'll see some speedup but it's all due to the higher frequency and energy usage.

Where are the SSE3 binaries? Can't be that hard?! I'd choose any minor speedup over nothing.

It's sort of useless to rely only on higher frequencies...

.. still, everything I'm running currently is 22nm, this shrink to 14nm must bring some power efficiency improvements (again, the whole noise limit thing means this could be a huge difference for me in growing my crunching farm without the wife complaining about fan noise, etc. Not to mention savings on the power bill.)

Hoping someone takes the leap and can post some Points Per Day estimates and maybe if possible some sort of Power Consumption vs. Points type metric (I can dream).

If I get my grubby hands on one I will, but it's not looking likely in the short term!

How about a big water cooling loop for your existing rig? There are power savings at 14nm but there's more electrical leakage with the smaller processes and the temps tend to be higher because everything is denser which increases resistance so it's not a huge power saving.

I'd expect you'd save more by getting the temps of your 22nm stuff down as low as possible.

As the Dr says, a release with SSE3 or 4.1 might make a big difference to throughput - not heard anything on the ralph forum for a while so it might be next semester before there's any news on that.

Really? I'd be interested at that price, where did you see it?

Newegg, but having looked further, it doesn't include VAT :(

Still, at £300 I'd go for it over the alternatives at the moment:

We have to wait September for restart the optimization, i think
In the other thread i suggest to contact another volunteer expert in boinc app development

Hmmm best I could find was 270 at http://aqalabs.com/epages/950018197.sf/en_GB/?ObjectPath=/Shops/950018197/Products/2107 so was surprised to see your post. Hopefully the skylake introduction will drop the price. We'll see

is anyone here running rosetta@home on the latest skylake cpus this time round?

care to share the experience?

what are the benchmarking gflops seen with boinc? what kind of credits/points is scored for rosetta@home work units? (do provide more details like the cpu time those work units ran etc). other key parameters, e.g. i7 6700k / i5 6600k / O/S 32/64 bit / overclocked / cpu temps / heat sink (cpu cooler) used etc? :)

As mentioned in a previous post, I am forced to stick with ultra-small-form-factor boxes (see this picture of my crunching farm) as to maintain approval of the wife who doesn't want my hobby taking up space or creating noise.

I'm super happy to see that there are now '~T' series skylake CPUs (thermally efficient ones that can run full tilt in these mini-ITX formfactors) starting to become available from Dell (I have my eye on the i7-6700T (SkyLake) OptiPlex 7040 Micro) and other OEMs. Once they come down a little bit in price I will add another box or two to my super dense crunching farm. (The two Micro form factor Lenovo boxes in my pic above I picked up for under $900 CDN, compared to the $1,600CDN price tag of these new boxes) XD

The i7-5820K lacks a GPU, so unless you're running headerless that's a small extra cost that you'll have to add. Also it has a TDP of 140W which might put some people off.

5000 series wouldn't be Skylake but rather Broadwell. So, thanks for the heads up about the lack of GPU support, but it's not related to this thread.

It's because I mentioned the 5820k as potentially a better-value option than the Skylake chips further down.

My guess is that the Skylake chips with eDRAM will be really good at Rosetta. Does anyone know how to get an idea of the likely speed-up available from eDRAM from the cache stats?

I don't have a link at the moment, but the two reviews I saw showed little improvement of Skylake over Haswell, which was not that much of an improvement over Ivy Bridge.

More than brute performance improvements I'm chiefly interested in power efficiency improvements at load, ie. "Performance-per-Watt". At first glance, it looks like the newer SkyLake models of the T series are able to achieve 8 threads X 2.8GHz clock speeds in the same 35Watt envelope my 4785Ts are only able to push 2.2GHz (at the same wattage). This looks like some sizable efficiency improvements in Clock-rate-per-Watt alone, afforded I presume by the move to 14nm manufacturing process. This kind of improvement is paramount to how much I can contribute given limits on allowed noise/power consumption as per wife. XD

You could heat your house with enough computing power. A bit of liquid cooling and creativity could go a long way!

I'm not in on this thread, but that deserves a lol on any platform :)

Skylake is undoubtedly more efficient, but the lower temperatures on the CPU are due in part to taking the voltage regulator off-chip. That does not save power, only lowers the CPU temp.
