Released in 2010, the Asus P7H55-M Pro and MSI H55M-E33 are desktop motherboards from Taiwan computer technology manufacturers ASUSTeK Computer Incorporated and Micro-Star International, respectively. Both components are incredibly similar, particularly in their naming; they are named after the Intel H55M Express chipset that they bear. They also have a few differences.
Form Factor, Processor and Memory
Both the ASUS P7H55-M Pro and MSI H55M-E33 use the Micro Advanced Technology eXtended, or microATX form factor measurement of 9.6 inches by 9.6 inches, or 24.5 centimeters by 24.5 centimeters. They are made for the i3, i5 and i7 processors that comprise semiconductor company Intel Corp.'s Core series, each of which are fitted on Socket 1156 to physically and electrically connect it with the motherboard.
Expansion Ports
Each ASUS P7H55-M Pro and MSI H55M-E33 offers four memory module slots, which can bear up to 16 GB of memory based on double data rate synchronous dynamic random access memory architecture, or DDR3 SDRAM. While the ASUS motherboard supports memory access speeds of 1,066 MHz, 1,333 MHz and 2,133 MHz, the MSI motherboard supports rates of 1,600 MHz and 2,000 MHz as well. Each motherboard has four Peripheral Component Interconnect ports for expansion cards such as sound cards, modems and TV tuner cards.
Audio/Video
The audio capabilities of the ASUS P7H55-M Pro and MSI H55M-E33 consist of an eight-channel Realtek sound driver called the ALC889, with an optical Sony Philips Digital Interface output. The video/graphics controller is also built onto the motherboard, with that of the ASUS taking up to 1.7 GB and that of the MSI using up to 512 MB for video memory. The video connectors consist of a Video Graphics Array port for analog video signals and Digital Visual Interface for digital video signals, as well as a High Definition Multimedia Interface for transmitting uncompressed digital audio/video content.
Other Connectors
Each ASUS P7H55-M Pro and MSI H55M-E33 has a built-in Ethernet driver -- with accompanying RJ-45 jack -- that provides up to 1,000 megabits, or one gigabit, per second in data transmission for wired networking. Other connectors apart from the Ethernet jack include six USB 2.0 ports, six Serial Advanced Technology Attachment interfaces for disk drives and each providing a transfer rate of 3 GB per second, and a Parallel ATA port accommodating 100-MHz and 133-MHz data transfer speeds.
