Intel's Atom Architecture: The Journey Begins

The Product Lineup
Alongside the technology disclosure, Intel is also unveiling the first five Atom processors that will be shipping this year:
| Clock Speed | TDP | Average Power | Idle Power (C6) | FSB | SMT | Price | |
| Intel Atom Z500 | 800MHz | 0.65W | 160mW | 80mW | 400MHz | No | $45 |
| Intel Atom Z510 | 1.1GHz | 2W | 220mW | 100mW | 400MHz | No | $45 |
| Intel Atom Z520 | 1.33GHz | 2W | 220mW | 100mW | 533MHz | Yes | $65 |
| Intel Atom Z530 | 1.60GHz | 2W | 220mW | 100mW | 533MHz | Yes | $95 |
| Intel Atom Z540 | 1.86GHz | 2.4W | 220mW | 100mW | 533MHz | Yes | $160 |
We originally expected Atom to top out at 1.60GHz but it looks like Intel wanted an even higher performing 1.86GHz part in the mix. At 1.86GHz, the Atom should offer performance beyond that of a 1.0GHz Pentium M - not bad for having a 2.4W TDP.
The pricing is admittedly higher than expected, at least for the chips with Hyper Threading (SMT) enabled. Given that the Atom processor is effectively targeting UMPCs and MIDs, the pricing structure makes sense but in order to get x86 everywhere Intel is going to need to offer higher performance at its lower price points.
Centrino Atom
As we've reported before, along with the Intel Atom brand comes the new Centrino Atom brand. The requirements are as follows:

This was an absolutely fantastic article as far as I'm concerned. One of the best I've read from AnandTech. I'm truly impressed with the amount of effort and dedication that the engineers at Intel put into the Atom. Thought the consumer may not see its importance today the Atom will continue to develop one throughout the next 2 years and show why this is such a huge step in the right direction. I really think that this article outlines very well the architecture involved and where it intends to lead Intel and others in the future.I'm always impressed to see Intel take architecture that was revolutionary in its time 15 years ago in the Pentium and Pentium Pro and resurrect it in modern day fashion with help of the Dothan Pentium M architecture and even things borrowed from the miserable Netburst technology that 15 years later I believe will once again create a product revolutionary in nature. I was never able to appreciate it in the days of the Pentium but certainly can now.
This is one product I think is deserving of being excited about.

What does an on-die memory controller have to do with ILP?Anand Lal Shimpi - Wednesday, April 2, 2008 - link
Woops, I've clarified the statement :)Take care,
Anand

I was thinking that this would be a fantastic platform for making a small, silent HTPC box for doing streaming media, but the lack of 1080p output kills that to a large extent. I know it's not a big priority for the first revision given the UMPC targeting, but I hope the "Atom 2" does try to squeeze that feature in.FITCamaro - Wednesday, April 2, 2008 - link
It could always be paired with a different, more capable graphics core.ltcommanderdata - Wednesday, April 2, 2008 - link
It;d be very interesting to see how the 1.86GHz Silverthorne stacks up against a 1.8GHz P4 Northwood, a 1.86GHz Dothan, a 1.8GHz Conroe-L based Celeron, and a 1.8GHz Athlon 64.I wonder if Apple is going to refresh AppleTV with Silverthorne since it seems ideal with replace the current 1GHz ULV Dothan in there.

Well at least Intel did not name their Atom CPUs the 'Atom Z80' . . . heh.Anyways, this is good for our future, as the mITX, and pITX 'systems' now days are still kind of large-ish, and cost quite a bit of money for what they are. Though, I think that putting a web browser on just any old appliance in the house would be way overkill, and possibly a very serious mistake. A TV with a web browser ? An Oven ? Please . . . this is why we have PCs, and micro mobile devices.
Recently a friend and myself have been working on an embedded project, and I can see the potential here, but a 'problem' does exist. Some of the things you would want to do with such a processor . . . well lets just say there still would not be enough processing power. That being said, I do not see why these could not help make a TVs/HD-DVD player menu operate faster.

It certainly sounds nice, but the atom processor cost alot because some of the higher end models cost more than $100 each. I find it surprising that their Polosbo chipset is manufactured at 130mm. It probably came from one of their foundries that was due to upgrade to 32mm sometime next year anyways. They could've earily manufactured at 65mm.Somehow I don't see their product as mature and maybe the next gen product they would have a cpu and the north/south bridge in the same die.

I honestly don't get the excitement. Should I? I mean, I wouldn't feel comfortable with one gigantic company controlling every single electronics in our life. If Intel opens up the X86 and everyone can compete on even end, then maybe. Since that won't happen, the future looks scary enough.clnee55 - Wednesday, April 2, 2008 - link
NO, how can you get excitement. I am already bored with your conspiracy theory. Let's talk about tecnical issue here.
