EEE PC - CPU for 700, 701 and 900

There is a lot of confusion about the EEE PC CPU, especially about CPU clock and cache size.
All models released so far use an Intel Celeron-M ULV (Ultra Low Voltage), model 353.

CPU Cache (from the Celeron M 353 datasheet) :

• 32KB L1 instruction + 32KB L1 data cache (write back)
  
• 512KB L2 cache

CPU frequency

• EEE PC 700 (2G) : 571 MHz (from original 800 MHz)
• EEE PC 701 (4G, 8G) : 630 MHz (from original 900 MHz)
• EEE PC 900 : the original 900 MHz

Front Side Bus: 400 MHz (original...)

It is possible (and you void the guarrantee!) to overclocking the CPU and/or replace the CPU with a Pentium-M ULV.
