I just ordered a i7-4770K, a MSI board and G.Skill ram to replace my current main rig. Been itching too long to build a new main rig:) I also have two MSI GTX 780's coming to replace the 7970's.

Using the ppd above, and these wattage numbers:
5.3k ppd/ 166 watts = 31 ppd/watt
5.75k ppd/ 213 watts = 27 ppd/watt

Roughly going by amazon prices I would say $300 for 3770k and $180 for 8350.
5.3k ppd/ $300 = 17 ppd/$
5.75k ppd/ $180 = 31 ppd/$

5.3k ppd/ 166 watts/$300 = 0.106 ppd/watt/$
5.75k ppd/ 213 watts/$180 = 0.15 ppd/watt/$

I was doing this math for my own curiosity but thought I would share.

lol, at least AMD reduced the 4.8GHz overclock wattage by ~220w with the FX-8350. I'd be interested to see some results from more modest frequencies e.g. 4.2-4.4GHz where you don't need a practically exponential voltage increase to be stable. I think we can agree that the first-gen FX chips were horrible, though.

EDIT: Some more numbers for you. Both my 3770K chips at 4.3GHz/1.2v read about 65w under full BOINC load at the package, and my 2600K at 4.0GHz/1.275v reads 85w under the same load. Package wattage was obtained using OpenHardwareMonitor and likely doesn't account for VRM or any other losses. Maybe sometime this week (like when I tear down my rig) I will get some numbers at the wall of my 3770K with integrated graphics and a Gold rated PSU. We'll see.

What is the ppd of the fx8350? What is its ppd/watt compared to say the 3770k?
PPD/W is certainly much better on the Intel CPU. From AnandTech's measurements, a loaded FX-8350 uses about a hundred watts more than a loaded 3770k--or nearly twice as much. But it's also $140 cheaper initially, so that helps.
I just ordered a i7-4770K, a MSI board and G.Skill ram to replace my current main rig. Been itching too long to build a new main rig:) I also have two MSI GTX 780's coming to replace the 7970's.
So many changes! Are you going to keep around the old equipment for crunching?

Maybe sometime this week (like when I tear down my rig) I will get some numbers at the wall of my 3770K with integrated graphics and a Gold rated PSU. We'll see.

CPUID HWMonitor says that my 3770ks @ 4.3/1.16v are low-60w at the package running a mix of WCG projects. Even with a crappy, massively-overrated 80+ PSU like I have it can't be more than 100w AC (running an otherwise minimal build with a pump, one fan, one RAM stick, and one HDD).

You guys really are tempting me into a FX---we'll see. Still more stuff to sell, and then it's a possibility :)


James, if you want to re-calculate I have to imagine that a minimal system is more efficient than the ones bit-tech is using (at least Justin's i7s and my i7 are much less than theirs are using).

I don't know about a vanilla clocked FX-8350, but my whole FX-8320 box pulls 280W[1] from the power grid when crunching.
Clocked @ 3.9GHz, it does over 6K ppd. That is, when I run it full time (which I rarely do lately due to a lot of gayming while booted to windoze)

[1] Note that my box has three HDDs, an optical drive, a shitload of high performance of fans and runs the Nvidia's GTX 560 (AKA Fire Hazard Chip) in its full power mode / top clocks [to drive two monitors w/ high refresh rate]. Thus, I'd guesstimate the CPU itself pulls at most 180W.
Also, I don't remember seeing it pull more than 140W as reported by HWMonitor while running linpack.

Just my 0.02€ into the topic.

If the CPU is rarely more than 140w then I'd imagine a bare-bones setup (1 HDD, 1 or 2 fans, and like a Geforce 8400GS) would be no more than 200w load, even with a relatively inefficient PSU. Gold could probably get it down to maybe 175w.

My FX-8120 box draws 150W from the grid. Runs @ 3.5 GHz and does ~6.1K ppd.
It would draw less, but I have a PSU with piss-poor efficiency.

Yes I am!
My system specs are up to date here on the forums, showing the OSes.
('cept that the CPU / memory clocks listed there for my main box are "gayming" clocks. I use that for, uhm... "gayming", OFC. :laugh: But too hot / inefficient to crunch.)

Well, all things considered 6.1k PPD from 150w isn't too bad. What PSU do you have it running with?

Wow--I should really put Linux on my dedicated crunchers. That's quite a good bit better (by about 25-30%) than I'm getting under Win7 on my 3770k.

:eek:

Wow. I'd imagine that Linux+24/7 on the 3930k would get 11-14k then---shame that neither of those are feasible. At least I can probably get more out of the 3770k and then the 2700k and whatever else I have as dedicated crunchers this fall..
and alas:

It's Corsair CX500
:p

That's not that bad...
I thought that it was like a Dynex or something junky like that. Even the cheap Corsair PSUs do fine.

wow, why would that be? I'd think that both 64bit clients would give the same ppd regardless of OS. I know that Windows uses more resources than Linux but even Vista idles at 1-2% load.

Two options: either the BOINC benchmark on Linux scores higher (this is why x64 is better than x86, mostly, as the benchmark scores higher) or there are things under the hood that are more efficient. I am surprised, however, as with a modern system idle load is basically 1% or less--which wouldn't be responsible for the 25%+ delta seen.

I will look for some other wattage numbers, bit-tech was the first I found.

I poked around through about 6 different 3770k reviews. Load wattage ranged from 112-222 with most having ~140. If I changed the wattage to the numbers you guys give me:

Using the ppd above, and these wattage numbers:
5.3k ppd/ 100 watts = 53 ppd/watt
5.75k ppd/ 150 watts = 38 ppd/watt

Roughly going by amazon prices I would say $300 for 3770k and $180 for 8350.
5.3k ppd/ $300 = 17 ppd/$
5.75k ppd/ $180 = 31 ppd/$

5.3k ppd/ 100 watts/$300 = 0.17 ppd/watt/$
5.75k ppd/ 150 watts/$180 = 0.21 ppd/watt/$

This will be my first water cooled cruncher/folder project using the PowerColor LCS 7970 that I've just received from the54void :)

I will start a thread of the rig rebuild later in the week but here's the quick rundown of the pieces.

Case- Fractal Define R4
Mobo- Asus M5A97 Evo
CPU- FX8350
Ram- 2x4GB Corsair DDR3 1600
GPU- PowerColor LCS 7970
Cooler- Swiftech H220 (customized)
PSU- Corsair TX850 or SeaSonic X-Gold 750 (haven't decided yet)
Fans- Yes... plenty
*final specs may change during the rebuild

This a rebuild of the Norton 3 rig in my sig and all possible due to the generousity of the54thvoid (Thanks again Bud!) :toast:
