E8400 is amazing!
Okay, so I JUST got it installed, and the drivers running. Pics are coming soon. But here's some tastey tidbits for you so far....
Power Consumption:
Old system 5000+ Black Edition @ 3.0GHz // Gigabyte M55 nForce 4 SLI motherboard
CnQ idle: 86W
F@H (50-60% CPU load) 136W
New motherboard/CPU @3.33 GHz
EIST Idle: 74W
F@H (50% cpu load): 89W !!!!!
I'm not sure if core temp is working, because it's been reporting 37C with no variance. I can tell you that I'm running the ninja SEMI-passive as you'll see when I get the pics up.
Right now I'm folding to check stability and make sure my temps are good, and to break in the AS5... folding should be a nice little benchmark as well.
Speedfan isn't really giving me believeable temps either. The Intel sensor is telling me 0C, and I've got 2 other temps that say 33C... which sounds more reasonable.
I can only speculate if I had gotten an E8200, stock speed, undervolted, with the brand new power saving motherboard what the numbers would be like.
EDIT: so far, 17 minute checkpoints on FAH, as compared to 25min on the AMD.....

F@H only stresses 100% on a single core, or roughly 50% on a dual core, unless you have the SMP client. I'm currently not running SMP client because I had some problems with the work units I was getting.
It would be fantastic for an HTPC based on the low amount of heat it produces and the per-clock cycle efficiency.
Motherboard is a Gigabyte GA P35 DS3R, it's the cheapest "ultra durable 2" motherboard I could find. They have newer, more efficient designs of this board they just came out with.

Thanks. I'm interested in using the GA-73PVM-S2H board. It has the integrated HDMI ports and supports the 3.0 shaders and stuff. I'll look into it some more.
3Dmark06 score:
(previous score same video card and ram was 9852)
Did I mention there is no fan directly on the Ninja? Here's how I'm running it right now.
There's an 800rpm noctua case fan about 1.5" away, there is also about 1" of the scythe slipstream 800rpm that blows through the S1, past the video card. and up on the ninja. The ninja is only about 1" away from the power supply fan, as well.

Can you please state what you old system was since you have updated your sig to the new system?djkest wrote: Power Consumption:

I’m curious to know what the power consumption is if you run Orthos (large in-place FFTs). It’s a commonly used utility for benchmarking so there’s a lot of data for power consumption.
How about trying to under-volt at stock speed and testing power consumption; a lot of people are interested to know how well these under-volt.
Finally, what is the full spec for your system including VGA and power supply? (I've just noticed your sig so I assume that was the spec you tested with)

and/or use the Intel Thermal Analysis Tool.

Side topic: The Slipstream will perform better on the back of the case than the noctua S12 (and the noctua will do fine on the video card heatsink) so you might want to swap those

Which fan is quieter the Scythe or the Noctua? I have some Yate Loon DS12L that I want to replace, the bearing noise is noticeable up until 5V. I heard that the Noctua's don't perform well with pressure? How are the Scythe SS 800RPM in comparison. Which has better bearing noise?

djkest: it would be really nice to see some undervolting results. lovest stable voltage, and power consumption during dual prime95, orthos or...
the more i read, the more i see how crazy this cpu actually is. passivly cooled at 3,6ghz its just insane. im using a TRUE and a noctua @ 600 rpm, meaning i could probably run this baby close to 4,0ghz without a sound

I'll do some testing pretty quick here for the undervolting crowd. Right now I'm running 3.6GHz with a modest bump in voltage. To get faster I had to use quite a bit more voltage, which... makes more heat and power. Oh yeah, temps are good at 38C while folding via SMP client, 100% load on 2 cores.
I've got Prime 95 25.5, I can use that for a good benchmark for power testing. System specs are in the sig. A big part of my "success" is the Corsair VX450 that I recently added. Thing is amazing.

I suppose they are 6 months away or so. I expect the E4x00 series will be replaced with 1066 FSB and 3 MB cache chips. I wonder what the E21x0 chips will be replaced with, 1.5MB cache!mcv wrote:A cheap low-end version of the E8x00 would be very interesting.
I suppose the Celeron dual-cores might jump up to 1MB cache which would make them more competitive as the current 512MB cache is too compromised in many situations.
