L2400, Core Duo 15W

I must have missed this one.

That's going to be an interesting processor for new thin and light models because 1) it's not slower than regular 31W Core Duo processors (T2400 and L2400 both have 1.66GHz clock speeds) and 2) it's a full dual core processor. Intel is even listing the Core Duo on the desktop page, something they didn't do with Pentium M (yeah, i know VIIV): http://www.intel.com/products/processor/index.htm?iid=HMPAGE+Header_2_Product_Processors

this is the low-voltage version which is normally packaged as microFCBGA. these are usually the dies located at the edge of the wafer. some of these dies also end up as Celeron-M during the time of Banias and Dothan.

Whoa, hold on a second. The sweet spot on a wafer is the middle, not the edges. It should be pretty obvious why since it uses optical masks.

What I pointed out above was that 1.66GHz is both a regular launch speed grade and a low voltage speed grade. If you look at previous Banias or Dothan LV chips, they top out where regular mobile chips started. For example, Dothan launched at 1.7/1.8/2GHz (lower speeds came later) and the low voltage chips (7x8 models) top out at 1.6GHz to this day. The Dothan LV launched at 1.4GHz: the Pentium M 738 10W TDP. Ultra low voltage Pentium M chips (7x3 models) top out at 1.3GHz, and were launched at 1.0GHz and 1.1GHz, 5W TDP. The speed/power grade on this L2400 is unique, which was what I was trying to point out.

But you are somewhat right about the edge chips being used as Celeron-Ms. Sometimes they are and sometimes they aren't.

Wow, that is quite revealing of the quality of Intel's 65 nm Yonah yields. Intel seems to be very satisfied with, or at least confident of their current yields.
