Gigabyte P55-UD6 and P55M-UD4 Motherboard Reviews

Jump To:


Gigabyte’s P55 Lineup

Today for the P55 launch we have two of Gigabyte’s 11 P55 motherboards up for review. The GA-P55-UD6 is their high-end P55 motherboard with every feature known to man crammed onto an ATX motherboard. Ok, maybe not a every feature but close. The GA-P55M-UD4 is their high-end P55 mATX motherboard featuring the vast majority of the options on the GA-P55-UD6 albeit laid out on a compact mATX canvas. The only thing missing on the GA-P55M-UD4 is the TPM security module, the onboard LED debug reader, half(12) of the power phases, and a few expansion slots which might sound like a lot but in reality isn’t nearly that much.

Gigabyte P55 Motherboards

Intel’s LGA1156 is a new socket with new processors and a new chipset. Codenamed Ibex Peak, Intel’s P55 platform consists of the LGA1156 processor and a platform controller hub(PCH) which contains the SATA and USB controllers. Since the PCI Express controller has been removed from the chipset and placed on the CPU, the processor now communicates to the PCH via a direct a direct media interface in a similar fashion that the X58 north-bridge communicates with the ICH10R south-bridge on LGA1366 boards. This also means that the chipset now consists of just the PCH chip, making board design all that easier. Below are the specification lists for the two motherboards we will be reviewing today.
