Intel has released some information about Silverthorne, its upcoming x86 design for UMPC's and laptops.

Justin Rattner, Intel's CTO told ZDNet.co.uk that Silverthorne was:

• fully Core 2 Duo compatible
• hyperthreaded
• Virtualization support
• usable performance at 1/2W
• dynamic power usage - it will use more power when more performance is needed

There was also some news on the Tukwila front:

• 65nm Itanium based design
• 2 Billion transistors
• 30MB of on-chip cache
• dual integrated memory controllers
• QuickPath interconnect
• runs at up to 2GHz
• multi-threaded quad core (eight threads total)
• more than twice Montvale 9100 performance
• uses only 25% more power than Montvale 9100

Intel was also talking about phase change memory, a possible successor to flash. This technology will store two bits per cell by storing one of four possible states in each cell. Intel also apparently discussed a new type of DRAM that is as fast as SRAM, but with twice the density.
