The Clarkdale Review: Intel's Core i5 661, i3 540 & i3 530

Power Consumption: Great but not as Good as Lynnfield
The biggest efficiency advantage Lynnfield held over Bloomfield was its extremely low idle power consumption. Clarkdale seems to ruin that thanks to its 45nm IMC/GPU on package. Idle power isn't bad, but noticeably worse than Lynnfield. Update: Many have pointed out that this may be a characteristic of our ASUS H57 motherboard, and that idle power is much more reasonable on Intel's H55 board. We're currently in Las Vegas for CES but upon our return we'll look into this further.
Load power is just dreamy though. This is ultimately what makes Clarkdale competitive. The i3s have the performance to compete with AMD's low-end triple and quad-core CPUs, but if they're anything like the i5 661 they have much better power characteristics than the competition.

If this is a sign of things to come from intels 32nm, AMD must be laughing their asses off.Every one of these cpu's is an overpriced piece of garbage.

Phenom II X2 550 should be on this list, it's the direct competitor to the i3 -- dual core with real cache. It beats the Athlon II X4 processors and the Athlon II X2 don't even belong.ereavis - Monday, January 4, 2010 - link
blasted no edit function. The 550 is also about the same price point.Guess I didn't combine criticism with the fact that this review was exactly what I've been waiting for and very well written, I like the added IGP page as I'm sitting on a 785 IGP while discrete cards are in between releases. All of which may get passed on to my mom's dying Sempron if an I3 deal pops up.
Also minor correction, the Phenom II 925 is an X4. Where are the release dates?

I second your question to Intel about the pricing of the 32nm i5 chips...who the hell is going to buy that? The i3's are looking pretty sweet as an alternative to an AMD HTPC platform at that low price point, though. March should make for an interesting competition once AMD launches their new RD890G (4350 based) chipsets. I'm guessing those will thoroughly trounce the GMA part on these chips as well as having quite a few features that the Intel HD stuff can't do, but at least Intel put something up that isn't completely laughable for once.Cogman - Monday, January 4, 2010 - link
x264 is NOT a codec. Let me repeat that, x264 is NOT a codec. It is an ENCODER. The video output from x264 is in the H.264 standard (or codec if you like).Saying that x264 is an alternative to H.264 is retarded. It isn't an alternative, it USES the H.264 standard. Its like trying to say that mySQL is an alternative to the Ansi SQL standard. It isn't an alternative, it is an implementation of it.

hahaha..that always gets on my nerves too!but you can take it as a compliment that x264's popularity is strong enough that people mistake it for h264..
people make the same mistake with divx, kleenex, qtip, xerox, etc...

My apologies for sounding like a fool :-) I've updated the text. I just meant that it was an alternative to closed source H.264 encoders but my phrasing was absolutely horrendous for that purpose.Thanks for pointing out the error :)
Take care,

I would like to see you measure the power consumption on the DH55TC using the integrated graphics.Legitreviews shows Idle/Load of 49/99W for the 661 in that setup.

Agreed - I'll do it as soon as I'm back in the office. Just gotta survive CES :)Take care,

Dual core 3.3Ghz CPU + Radeon 5870 consuming only 110 watt at load???
