B85 and Z87 are 8 series motherboards, suitable for use with Intel's four-generation Haswell processors, these two processors are currently the main installed users choose the largest number of motherboards, the difference between the two, we can use the following picture, easy to understand.
From the above B85 Z85 contrast, Z87 and B85 of the corresponding slot type of the motherboard is LGA 1150, the main difference is:
Z87 motherboards Support overclocking , support SLI or CF, RAID-enabled, rich interface;
The B85 motherboard does not support overclocking, does not support CF or SLI, does not support RAID, the interface is relatively small, but basically enough.
B85 and Z87, which one?
So which of these two model boards is good? For this issue, we also need to consider from the CPU, price/performance, such as Xeon E3 1230v3 support B85 and Z87 motherboard, but because E3 1230v3 does not support overclocking, so the best match or lower price of the B85 motherboard, with better cost-effective.
The Z87 motherboard is better suited to support overclocking high-end Intel processors, such as i5-4570k, i7-4770k, and so on.
For users, the B85 motherboard has USB3.0 and SATA3.0 and other mainstream interface, enough practical, and lower price, the best match is i3-4130, i5-4570, E3 1230v3, etc. do not support overclocking middle and high-end processor;
Z87 motherboard price more expensive, but support Overclocking is the biggest selling point, therefore more suitable to match i5-4570k, i7-4770k and so on high-end lock frequency, overclocking processor collocation.
