ExtremeTech have a nice article about VIA's C5P processor, the codename for the C3 CPU that will live inside next year's Nano-ITX motherboards. The C5P is a more efficient design of the C5XL (Nehemiah C3) processor. When designing the C5P, VIA took away around 280,000 transistors and added around 180,000 for new security features, keeping all the instructions of the previous Nehemiah and drawing less energy at 1GHz (allowing for a smaller die size). More about those security features - the existing Nehemiah C3 processor already has a hardware RNG (Random Number Generator - useful for encryption), and the son-of-C5XL (C5P) will add to this with full hardware-based AES encryption. This is a canny route for VIA to take - initial tests have shown that an inexpensive C5P based PC will encrypt in hardware with a throughput an order of magnitude faster than the fastest Pentium IV can encrypt in software.
