Intel has emphasized on Menlow 2008 platform during IDF and unveiled 5 Atom “Silverthorne” processors along with Poulsbo chipset. Intel called Poulsbo chipset as a System Controller Hub (SCH) that basically combines the MCH and ICH into a single chip. VR-Zone learned that there will be 3 SKUs; US11L supporting 400FSB Silverthorne, 512MB DDR2, 100MHz graphics core clock, SD Video only and up to 800×480 resolution, US15L supporting 400FSB Silverthorne, 1GB DDR2, 200MHz graphics core clock HD Video Decode and up to 1366×768 resolution and US15W that has similar features set as US15L but supporting 533FSB Silverthorne.

UMPC Roadmap Intel UMPC & MID Roadmap Unveiled

Intel has emphasized on Menlow 2008 platform during IDF and unveiled 5 Atom
"Silverthorne" processors along with Poulsbo chipset. Silverthorne is 45nm based
and has 512KB of L2 cache. The 533MHz FSB models (Z520, Z530, Z540) supports
Hyper-Threading and the 400MHz models (Z500, Z510) do not. The TDP ranges from
0.65W for the Z500 to 2.4W for the Z540.

3 SKUs; US11L supporting 400FSB Silverthorne, 512MB DDR2, 100MHz graphics core
clock, SD Video only and up to 800×480 resolution, US15L supporting 400FSB
Silverthorne, 1GB DDR2, 200MHz graphics core clock HD Video Decode and up to
1366×768 resolution and US15W that has similar features set as US15L but
supporting 533FSB Silverthorne. The 3D graphics core is powered by PowerVR SGX
Series5 instead of Intel integrated graphics cores like GMA 3000, X3100 etc.

Although Menlow 2008 platform is about one third smaller than the McCaslin
2007 platform but it is still too huge to be used for Smartphones so it can only
be targeted for MIDs and UMPCs segment right now. Intel has shrank the CPU
significantly by employing 45nm process technology for Silverthorne vs 90nm for
Stealey, however, the Poulsbo chipset which is made on 130nm is still too large.
Intel needed something much smaller fast so they have a Moorestown platform
slated for 2009. Moorestown platform is indeed much more exciting where Intel
touted a Lincroft CPU that has on-die graphics core and memory controller and a
Langwell IOH that supports solid state devices. Moorestown total footprint is
only half of Menlow which makes it an ideal candidate for smartphones but only
consumes only half the power and essentially doubled the battery life.
