VR-Zone.com managed to lay our hands on Intel's latest Little Falls ES mini-ITX solution, featuring their latest low power processor, the Intel Atom. The Atom on the board is based on the Diamondville core, clocked at 1.6Ghz and comes with Hyperthreading technology. This is the first time that Intel incorporated their own chipset into their mini-ITX solution, previously employing SiS chipset solutions with their processors. we ran some power test on the board, and together with our FSP Everest power supply, 7200rpm 80gb hard drive and a sata dvd-rw, it draws roughly about 32 watts (assuming 80% efficiency, power meter shows about 39watts) of power. Something cool, check the video out for more information. Read More >>

2. You did nothing except to insist that I was not making any difference but first of all, he was not even accurate in his post and you were and still are trying to justify that. As I've said, if you can do a better job, prove it and I'll shut-up.

3. I can cook and I have a huge tolerance when it comes to food. If I'm going to slam any cook, odds are the food is way-worse than combat rations.

4. It's not a mistake as far as I'm concerned. I've already explained in my previous post with regards to the PSU. Since you can't understand some basic logic and math, I shall stop replying after this.
1. Good. Next time your car break down, take it to the nearest bicycle repair shop will ya?

2. Nope. Didn't say "you didn't make a difference". Said "your shoddy justifications didn't make a difference as the fact that the reviewer didn't have the equipment THEN he should warn the readers that those are rough figures BECAUSE he is unable to estimate the efficiency of his PSU." By saying "Oh I am using a 80% efficient PSU..." We less proficient readers tend to think "Oh the total power drawn is 100W. 20% is lost... so actual draw is 80W or thereabout. Sweet." And Oh if readers are expected to more expert than that... then that reader should be the one doing the review instead.

3. Nowhere did I slam the reviewer. In fact I appreciate the review as I am looking forward to the Atom. I merely questioned your stupidity in slamming the poster who highlighted issues with the review which help readers adjust the meaningfulness of the figures provided.

4. Have a nice day. Let's stop talking to each other. Thank you.

2. I made no criticism except to point out that the point made by that guy is perfectly valid and justified. I assume people here have passable comprehension but obviously short and sweet comment won't work. Smartalecs would equate short posts with "pruss one" posts it seems.

3. So you go to a restaurant and the food is bad. However you can't cook. Thus you can't criticise the bad food. If that is your opinion, have a nice day.

4. It is not a point of whether I am capable or not, the point is the reviewer made a careless mistake (or maybe he didn't know the 20/50/80 at all, I will be the 1st to admit I didn't until Jack commented).

5. Good to know that you are such a loyal friend that no one can make any negative comments on the articles of your friends.

6. I don't like to make long negative posts but well done you forced me to.

Obviously, you're expecting what is above and beyond the limitations faced by the team without making any useful contributions or even offering any useful comments. You might as well have posted a +1 and that would have been a better post.
I don't like to make such posts but it's blatantly obvious that something so simple is completely oblivious to you. Nothing irks me more than people who insist on critising others when they have nothing to show that they are capable of better.

the point is this -> wait till the final product then we'll see. By then, we'll all keep quiet and wait.

for all

Furthermore, DC-DC convertors require the use of external switching adaptors that probably do not meet 80+% efficiency themselves and you're back to square one.

Since this is a quick preview (the Little Falls production prototype is actually still classified as Intel Top Secret), it obviously spells of the tight timeline and you cannot plausibly and reasonably expect the labs to acquire a DC-DC convertor or a 200W Flex-ATX 80+ PSU; nor should you expect a review site that typically runs Kentsfield, Yorkfields and SLI/ Crossfire setups to actually possess one of these.
So... does this make a difference to the point raised?

Could you please disclose how much the system used in idle?
39W full load is nice, but I really want to know if <20W idle is possible with the Atom.
