I would like to see someone put up 2 identical systems, at the same time, running the same profile, one with i5 and one with i7 and see what the real differences are, including electrical usage.

That's pretty much what I was hoping someone else had already done, an apples to apples, clock to clock, i5 vs i7 BOINC shootout. Help me buy one of the processors and I'll tell you.

mmm... 70% seems like too much. I don't crunch on it anymore but I recall my i5 @ 3Ghz netting ~4K and my 3770K does 5K w/HT and a 500Mhz advantage per core.

 

[xvi]

I guess I tend to focus mainly
on multisocket server chips which I assume all have HT. I think there are some single socket Xeons that don't but I dont' recall seeing MP chips that don't.

My dual LGA771 Xeons do not have HyperThreading. AFIK, no LGA771 Xeons do. I think the more recent Xeons are pretty much HT only though.

Anyway, I'm curious about Skylake. I haven't really kept up with the tech and I need to get back into that to some extent, so what makes it so special as compared to Haswell. I know from wikipedia and couple of other articles that it's a die shrink but I didn't see anything about performance improvement. I noticed that it will have an on-die GPU with multiple EUs but unless those can be used for crunching, I'm not sure what makes the chip worth waiting for. Thanks.

I don't think we'll see performance numbers any time soon since the release date is speculated to be pretty far away. Wasn't Devil's Canyon the die shrink? Won't Skylake be Intel's "Tock" cycle? I thought we'd see a new architecture. GPU side, I heard we'll see Iris Pro.

Judging by those numbers, it's about a 7% increase per clock.

Looking at my i5's, a 2500k @4ghz on linux and a 3570k @4.6ghz on windows, on boinc stats I get an average credit of 4800ppd. I game quite a bit on the 3570k' or else it would be higher. Like today the 3570k got 5542 ppd according to boincstats. When I had my 2500k @4.8ghz on linux it was getting a bit over 7k ppd if I remember correctly.

I5 2500k's have been going for $125 on that reddit link I posted way back.

@xvi Yeah, it's a tock cycle but a die shrink from Haswell - that's what I meant. 14nm from what I read. But it looks like it's also delayed from some recent articles I saw. Looks like Q4 of 2015 - http://www.itworld.com/article/2842...release-of-skylake-generation-processors.html

We're getting to the point where die shrinks are going to become increasingly problematic. At least that's what I read a couple of years ago. You're starting to get into the range where you need to worry about quantum effects like tunneling. I wasn't sure when they might start hitting that but I've seen some comments that said around 10nm. But maybe they're having some issues already. Although Broadwell doesn't seem to be delayed, so maybe it's just issues with the new architecture.

Kinda quiet tonight. Guess everyone is out shopping. I'm a little bummed that Colbert will be off the air as of tomorrow. [sigh]

I've been quiet since I assume the team doesn't want to hear about my pc issues or my wife's baby issues


But...

The wife is complaining of pain in the ribs, not sure what's going on. The doctor the other day said the baby is breached so kicking in the ribs is ruled out, but her main doctor said the baby wasn't breached and that pain is normal. Doctors... they know what's going on



Anyway, got my main rig back installed welland boinc running. My 4790 rig has been hit and miss because I just got an xbox and have been messing with that (on the same outlet as the pc and share an ethernet so I've been using only one at a time).


And I don't want to mention alcohol because I don't want to rub anyone the wrong way... Kai....

 

[twilyth]

Yeah, finding a good doctor is rough. But breach vs not breach - seems bizarre they can't figure that one out. They've heard of ultrasound right? LOL. These aren't the kinds of doctors that have a bone through their nose or something (j/k ).

You're electrical issues remind me of my place. I can use either the microwave, digital toaster oven, Keurig or espresso machine since they're on one circuit. The other circuit has a toaster, vacuum hot water dispenser and counter top dishwasher. I keep the dispenser at 175F for tea so I only need to worry about that when I boil a full batch, otherwise it stays hot mostly on its own. And the dishwasher is pretty small so that's never been an issue. Canadian brand - Danby. Love that thing.

At my Grandmother's house you have to shut off the kitchen light to use the microwave!

Hey, that sounds like this POS that I live in. My computer room, the bedroom, and the living room are all on the same.....................Frigging 15 amp breaker.

 

[twilyth]

I got a little gizmo to try to map my outlets to breakers but it doesn't seem to work. You're supposed to plug it into the outlet and then put the sensor over each breaker and its supposed to indicate which one the transmitter is connected to. Probably did something wrong. Should probably dig it out and try again at some point.

 

[agent00skid]

My mothers house have 3 circuits for general power, but they're wired through a 3-phase circuit breaker, so if one of the circuits overload, all of them gets turned off.

 

[Tallencor]

Then what am I doing wrong? 2600K @ 4.2 under Mint is averaging 6255. My 2600K @ 4.4 W7 system, that's also Folding, so therefore is only using 7 threads is averaging 5872. The only thought I have is that I am pushing CEP because I'm behind (must have run times even, ya know) with CEP. (currently only accepting work from CEP, UGM and OET)
@xvi I was seeing about 2000 ppd more for my OC'd i7's than I was for my i5-3450.

Okay so.
Home pc. 3770k 4.3 o/c h.t.
Work pc 3570 3.8 stock turbo non h.t.
I landed over the last 13 days boinc points.
632 for the I7 3770k and 629 for the I5 3570
Omg? I use both randomly so I guess the best time to get some more accurate #'s is challenge time or over the holidays I need a week of little to no usage for both. But I didn't expect it to be "that" close.
Edit: I will stock the 3770k with turbo on to be fair.

I've been thinking about swapping out the i3 2100 for a 2500k, but I've been waiting for a nice deal to come around. By the time I'm ready, I may find a nice price on a 3570k.

???? "3-phase?"

I am to assume your not in the US? Usually 3 phase is set to 277 volt and above in the US.

They seem to be going for $150ish. Really though, these are great high performance per dollar with low wattage crunchers.


I am leaving for the holidays apparently, and decided to bring some movies and other files on my flashdrive. 8gb of files transferred in 1.3 minutes with usb 3. 0. Gosh I love those little blue ports.

All sorts of power out there... USA, in general, goes from 110v single phase up to 480v 3 phase

 

[agent00skid]

Here it's ~400v if you run phase to phase and ~230v if you run phase to neutral.

 

[twilyth]

Higher voltage means fewer amps to get the same power/wattage so it's considered safer - is that how it works?

Tempting to reply to this 110 V thread but I pass

You guy's are offending my "Caveman Ancestry" with all this talk of electricity and such......can we go back to Alcohol please...????

 

[AlienIsGOD]

looks like i have to get a new case for the X41 as it has 140mm mounting holes. Looking at the Corsair 760T, if anyone has any other ideas http://www.canadacomputers.com/index.php?cPath=6_111&bsort=0&brand=0&price=0&location=KING feel free to chime in, just keep in mind that i have a E ATX mobo and need a 140mm fan mount (rear pref. ) It kinda has to be Canada Computers as its the only place i can spend that much cash (ie. no CC or PayPal)

 

[Norton]

I like the Fractal Define XL and Arc XL cases but everyone has their own tastes.....

*note- you should be able to use a mid-tower with 8 expansion slots rather than a full tower (CM HAF XM for example)
