The following is the positioning of the Intel platform:
Z: represents the high-end chipset, the highest specifications, the best general materials, can overclock K processor;
H: indicates mid - and low-end chipsets with low specifications and normal materials. Overclocking is not supported. (But some manufacturers will also crack support for overclocking, but immediately blocked by Intel)
B: Actually, it is a commercial chipset. Since the B75 was developed, it has been used as a mid - and low-end consumer chipset and does not support overclocking.
P: There is no official definition of this letter. Some manufacturers use this on low-end H chipsets to indicate that no output is displayed. Such as Gigabyte GA-P85-D3, GA-P81-D3, in fact, is still B85, H81 chipsets)
In 2018, the Ryzen series of processors on the AMD platform also had a similar positioning after the launch:
X: represents the high-end chipset, the highest specifications, the best general materials, can be overclocking processor;
B: indicates the mid-end chipset. The chipset specifications and materials are normal, and overclocking is supported.
A: represents the low-end entry chipset, due to the poor power supply of this motherboard CPU, although it can also be overclocked, but this motherboard overclocking damage to the motherboard is relatively large, and the CPU power supply is not conducive to overclocking;
