Two Cores, Four Threads

Clarkdale is the spiritual successor to Conroe - one of our favorite dual-core processors of all time. It's a dual core chip but with all of the magic of Nehalem. Meaning you get a 64KB L1 per core, 256KB L2 per core but only a 4MB L3 cache. Remember that the L3 cache is shared among all cores and Intel likes to keep the ratio at 2MB per core.

Each core is capable of executing two threads (Hyper Threading). There's of course going to be turbo mode, although the upside shouldn't be too huge on desktop Clarkdale processors.

A Clarkdale mini-ITX system

Clarkdale, like the rest of the Nehalem/Westmere family makes extensive use of clock gating. You also get a ~1M transistor PCU that is in charge of keeping power consumption at a minimum. The result is a chip that truly sips power:

69.8W under Cinebench load

Intel's Clarkdale mini-ITX system used less than 30W at idle and only 70W under load running Cinebench's multi-threaded test. The idle performance is particularly impressive - that's not too far off from an Ion system honestly, but with much better performance.

27.6W at idle

    "The problem is that when we go to buy a pc all we see is a processor name--i7 , i5, blah blah"

    No offense meant, but since I found Anandtech, I have never had to "go to buy a pc".

    All the info you need in order to build your own pc, to whatever specifications is all right here. Anandtech has "roudups" for different budget levels to help clear things up.

    It is sort of funny though, because I found the site originally after getting caught not knowing the difference between a "williamette", and a "northwood" when I tried to upgrade my own motherboard.

    Since then I've overclocked the snot out of every chip I've bought.

    Going to buy a pc for me means going to the it mall to a pc shop and choosing the mb cpu etc... and then the shop will put it together for me. and yes I agree that Anandtech has great advice on budget and other systems. the pc shops have pricelists of cpu's mb etc..--nowhere will those lists include terms like clarksdale or westmere or whatever--the wont even mention nm size.
    just choose your mb, cpu, video, ram etc...

    With a little patience you could build your own, with more power, better warranties, and best of all lower price. And to help, sites like Newegg, or Tigerdirect use the codenames in most of their product listings, and newegg can seperate by socket type. You sould give it a try it's fairly simple since SATA, you don't have to worry about hdd jumpers anymore, so it's pretty much just matching up similar connections. The real value though is in overclocking. ie 2.4 P4 @3.2, or 2.4 E6600@ 3.3, or a 2.4 Q6600 @ 3.6, or my newest 3.0 E8400 @ 3.6 it's free performance, and that is whats got me so excited about each die shrink. Every time the die gets smaller, the easy overclocking potential goes up.
    I'm looking forward to redoing and shrinking my HTPC, since my rig now is a full blown 680i Q6600 system, Not exactly efficient or quiet. sorry for the rant.

    except, the article focuses on the laptop cpu... which, last I checked, you can't really build yourself. Reply

    Evidentally you missed page 1. blah blah blah" Intel Clarkdale Desktop Processors"....."socket LGA 1156"...or maybe it was the title you missed."The Real Conroe Successor: Clarkdale & All You Need to Know about Westmere", or maybe it was in page 1 where a simple table states "Clarkdale | Desktop | 2 | 32nm"

    beside my response was agreeing that the code names are confusing.

    That's amazing, but good news because it will give AMD a great opportunity to recover. They can sell a quad against any Intel dual as long as the base clocks have the same first digit. Nobody (statistically) is going figure that even a double-throwdown super-trick over-and-under hyperthreaded handshaking pair will beat four of a kind, across the board. It might be true, but it won't sell at Best Buy. Reply
