Comparison of 7-series motherboard specifications

As the number of models reaches nine, including four z77, z77, z75, and b75 desktop models, the specification differences between five models of the notebook hm77, hm76, hm75, hm70, and um77 are rather cumbersome. Therefore, we specially collected some official technical materials from Intel, summarize the differences and differences between the nine chipsets.

Intel 7 Series chipset adopts 65nm technology and FCBGA encapsulation. The desktop version has 27x27mm, 942 welding balls, 0.7mm Ball spacing, 6.7 thermal design power consumption, and 25x25mm mobile version, the number of welding balls is 989, the ball spacing is 0.6mm, the thermal design power consumption is 4.1 W, and the standby power is 3.7 W. Only um77 for Ultrabook is 3.0 W.

The price is the same as previously disclosed. The four desktop versions are USD 48, USD 43, USD 40, and USD 37 in sequence, only $48 and $43 for hm77 and hm76 are available in the mobile edition. Others are unknown.

Analysis --

PCI-E 2.0 port: In addition to hm70, um77 are four, the other are eight, can be split into x1, x2 or X4.

PCI Bus: Only b75 retains native support, and all others are cut off. The corresponding motherboard can only be supported by a third-party bridge chip.

USB 3.0/2.0 interfaces: z77, h77, z75, and hm77 are all complete 4/10, b75 and hm76 are reduced to 4/8, um77 is 4/6, and hm70 is only 2/6, hm75 is 0/12 (USB 3.0 is not supported ).

SATA 6 Gbps/3 Gbps interfaces: z77, h77, z75, hm77, hm76, and hm75 are all complete 2/4, b75 is changed to 1/5, and hm70 and um70 are 1/3.

Integrated graphics core: all supported, p67 and other tragedies will not be repeated.

Video output: Except um77 does not support VGA/LVDS (this is not available in ultrabodes), all other specifications are supported, including VGA/DVI/HDMI/displayport/EDP.

Widi 3.0 Wireless Display Technology: All models of the notebook are available, but the corresponding modules need to be used.

Ahci: all supported.

RAID 0/1/5/10 disk array: supported by z77, h77, z75, hm77, and um77.
