Intel's embedded IA roadmap
Single digit TDP envelopes for all!

As if Intel needed any more reasons for people to like Yonah, the company just announced plans to build a 1.2GHz, 65nm Yonah processor with a 533MHz FSB and 2MB L2 cache.  But here's the kicker, the processor has a TDP envelope of 9W.  The new processor will sell under the name Intel Core Duo U2500.

Intel previously had a Pentium M Dothan SKU, the Pentium M LV 738, which had a TDP envelope of about 10W, but was a single-core processor.  Both the Pentium M LV 738 and the Core Duo U2500 are BGA processors, meaning they are soldered directly onto the motherboard.  These embedded processors are used for things like ultra portable tablets, UMPCs and Ethernet switches.  The Core Duo U2500 should be available immediately. 

Furthermore, Intel's roadmap reveals that 65nm Merom processors will also have Low Voltage variants.  At the Intel Developer Forum earlier this year Intel representatives announced that Merom would have more robust features when it comes to power management.  It certainly isn't hard to fathom that single digit TDP envelopes may become commonplace in the near future. Merom is expected to launch this August, although the Low Voltage variants of processors from Intel typically launch a few months after the main segments is announced.

completly silent?

Would this allow for a completely passive cooled HTPC (and silent!)? 1.2Ghz isnt speedy, but it should be fine for a HTPC...

Yes. Cooling 9watts is trivial even with a small heatsink. And don't forget it's 2 x 1.2Ghz and mhz to mhz Yonah is faster than A64 or Pentium M. Oh, and no need for active PSU.

heard of samsung's 32gb nand ssd?
think i read somewhere that it will be down to about $300 by the end of 2007.

Incorrect. MHz to MHz, Yonah is slightly slower than Dothan - I've measured this myself and was a little disappointed.

Nope. I really doubt you were the only one to get "proper" results. It is a fact that Yonah is faster than pentium M per Mhz. I've read at least 15 reviews and have empirical experiance.

Same here - I benchmarked a Pentium-m 533Mhz 2Ghz and a Yonah at 1.9Ghz (1.83Ghz with 5% overclock) - the Yonah was faster in every application I tested which were all single threaded running one at a time.

Does it switch of the second core off while running on batteries to keep TDP below 9w ?
Power and performance while connected to mains -vs- batteries ?

Umm, the original post was about an HTPC. You'd get annoyed not being able to watch HD pretty quick considering how much content there is.

720p AVC should be fine if the decoder can use both cores. Maybe even more if you add a passive nvidia or ATI card that can help out a bit.

Just drop in any nvidia card based on the last 3 generations and you should be just fine. Even 1080p content on my 3.4GHz only uses 10-15% CPU.

--[Just drop in any nvidia card based on the last 3 generations and you]--

...no longer have a 9W thermal envelope? :)

Seriously, I'm not sure I've seen many graphics cards designed for cool running, though perhaps they exist.

If the HD decoder can take advantage of both cores, then it should be speedy enough.

This was a good one . Pretty funny stuff . It seems Intel is like a fat guy who lost wieght after those hungry P IVs now it's all about low calories .
You show em' how it's done Intel , it consumes under 10 W and it still tastes yummy . No MHz to show off but you can't have them all can you ...

All the waste light from your overhead lighting and monitor, just recycle it with a solar cell.

And all the heat from your processor? Generate steam.

75 W?

It seams to me a maximum 75 watt power supply should be able to power a whole machine then.

At 75W this would make a perfect - lite 1U server. Very low maintiness.

I tend to follow DailyTech news through my google home page. However, it seems that not all news shows up there. For example this news item doesn't show. What's the deal?

9W max
By bombledmonk on 5/30/2006 4:21:20 PM , Rating: 3
I think some are also missing the point that this is 9W max, idle consumption will be much lower.

This type of processor is ideal for ultra portable notebooks and tablet PC's. I'm not really sure how anyone can call this useless. It is a very powerfull chip and could add tons of processing power where nobody is looking at the moment.




HiDef & HD noise

"you wouldn't be able to watch high definition content at full fps"

I wouldn't be so sure about that, dual 1.2 is pretty powerful. But anyway, once they release a 64 bit version of this that should help frame rates once Vista arrives. Also, don’t forget that integrated chipsets will have H.264 support soon, if I’m not mistaken.

As for quiet hard drives, use a laptop drive, they can be really quiet if you pick the right one.




HDD Silencers
By eckre on 5/30/2006 3:59:53 PM , Rating: 2
This HDD silencer is the only one that makes it QUIETER and COOLER. All the other ones seem to act as a oven, rather than a heat sink. Makes is a LOT quieter. Only audible while seaking, playing audio in a HTPC silent.

You probably won't even need a heat sink at all to keep it in the operating temp range.

You did realize this was BGA. No one can buy it of the shelf. Of course companies want to buy a processor with a guaranteed TDP and mhz instead of downclocking available socket-cpu's.

Benefits to consumers are devices like the following:

1. Low-cost, low-power embedded devices
2. Ultra/mini-PC's
3. Silent media center PC's

I think the nearest competitor from AMD is a 35W model, although I'm not totally up-to-speed on all their offerings.

The Turion MT-37 and MT-40 are both 25W TDP (which is probably around 20W if using Intels TDP scheme) running at 2GHz and 2.2GHz.

They also have an embedded memory controller, which means the motherboard would use less power than Intels. This is a pretty impressive chip, though.


RE: ZERO value to most consumers
By TomZ on 5/30/2006 10:54:00 PM , Rating: 2
So you're assuming that the memory controller only would be more than 35-9 = 26W? Not!

Intel also designed the chipset to be power efficient whereas the Turion processors have to make do with whatever VIA or Sis produce and even then it's not going to make a significant difference against the low wattage of the ULV processors.
