News - Intel-powered notebooks won’t support USB 3.0 until 2012

Early details about Chief River platform suggest high-speed interface is still a long way off.

My guess is it's a power thing - Intel doesn't want to push up the power consumption of its latest chipset because on the current process node USB 3.0 is still a bit hungry.

Besides, 480Mbps is enough for anyone. ;)

I am reporting that as flamebait ;)
It's a pain for me though, I am in a market for new laptop, and size and GPU aside, connectivity is very important to me. I won't consider a laptop without 3 USB ports with at least one port that's sufficiently fast to keep up with an external HD (eSATA or USB3).

I wonder how much power demand Lightpeak will add to the chipset compared to USB 3.0.

Pete, it would be very useful if you told us where we can voice our criticism to intel. I will try to find their feedback page later if i get some time. Without them coming up with a final usb 3 header pinout design, no company will commit themselves to usb3

If I knew, I'd tell you!

Unfortunately, Intel doesn't have an Apple-esque direct line/e-mail to the CEO.

Sounds right. Same reason gigabit ethernet is often hard to come by. Yes there is a cost difference in parts, but that is tiny. The power difference can be quite meaningful though.

Once I need USB3, I think I'll just end up with a little ExpressCard for a while.

Thread revival but I am looking for a laptop and I think its best to wait for this chipset (Chief River / Ivy Bridge or HM76 USB3.0 / HM77 +raid equipped) to be officially released, which by all accounts is this month and it hasn't happened yet.

does anyone know any more?

and I have just spotted Dell's New Alienware lineup in Q2. So I am inclined to think that the Ivy Bridge chipset will not be released for a few more months.

Most ultrabooks have USB3 NOW, whats the problem?

Decent Graphics card, more HDD's, ultrabooks are not what I am looking for. I'd like a desktop replacement so why not wait a few months when its likely to be round the same price as it's only the motherboard that will change.

How come AMD can integrate both USB3.0 and SATA3.0 on it southbridges and keep power consumption down?? Reviews indicate the Hudson D3 southbridge consumes relatively little power.
