CPU
The EPIC/PM is available with an Intel® Mobile Pentium®-M or Celeron®-M central processing unit
(CPU) from 0.8GHz up to 1.8GHz or 1.8GHz. However, other GHz as well as Celeron®-M versions (half
cache size, no SpeedStep® technology) of this board are available.
Intel® Mobile Pentium®-M CPU features include:
®
Supports Intel® Architecture with Dynamic Execution
®
High performance, low-power core
®
On-die, primary 32-kbyte instruction cache and 32-kbyte write-back data cache
®
On-die, up to 2-MByte (depends on CPU) second level cache with Advanced Transfer
Cache Architecture
®
Advanced Branch Prediction and Data Prefetch Logic
®
Streaming SIMD Extensions 2 (SSE2)
®
400-MHz, Source-Synchronous processor system bus
®
Advanced Power Management features, including Enhanced Intel SpeedStep®
technology (only for Pentium® M processors)
Chipset
The chipset of the EPIC/PM consists of the Intel® 855GME chipset GMCH (Graphics and Memory
Controller Hub) and the Intel ® 82801DB ICH-4 (I/O Controller Hub 4).
