Early look at GIGABYTE P55-UD5 and UD4P mobos
GA-P55-UD5, the high-end mainstream board with Intel Core i5 support
actually a P57 motherboard as it includes an Open NAND Flash Interface
(ONFI) slot, which adds flash memory to the system to speed up access
times and improve performance. This will not be supported by the P55
chipset.
the P55 based UD5 mobo is that it has - get ready for it - a grand whopping
total of 24 CPU power phases
Power over eSATA allows users to power external eSATA hard drives with a
single cable.data and power can be delivered over a single eSATA cable. Not
many devices support it at the moment
The next new feature on the list for both P55 boards is SATA-III / SATA 6
Gbit/s support. the chip used is from Marvel and is a SATA-II/III combo
design. It supports four SATA-III ports and six SATA-II ports with RAID 0
and 1 support as well as port multiplier
The major new piece of software is GIGABYTE Smart TPM,
The main difference between the UD5 and the UD4P is that the UD4P has
less power phases and less DIMM slots.
