lpddr4x内存什么意思(lpddr4x内存默认频率是多少)

LPDDR4X (LowPowerDoubleDataRate4eXtended) is an energy-saving optimized version of LPDDR4 memory. It is developed on the basis of LPDDR4 and mainly improves power management, thereby reducing power consumption.
Compared with LPDDR4, LPDDR4X achieves lower power consumption by optimizing the power pin design and test specifications on the package while maintaining the same frequency, bandwidth and operating voltage. Depending on the manufacturer, LPDDR4X can achieve approximately 10-20% power reduction.
LPDDR4X is mainly used in mobile devices, such as smartphones, tablets and other portable devices, which have higher requirements on battery life. Its low power consumption makes it ideal for this type of device, while still providing high-speed data transfer performance. Due to its high efficiency and low power consumption, LPDDR4X has become one of the mainstream mobile device memory solutions on the market.

The difference in power consumption, speed and bandwidth capacity.
1. Difference in power consumption and speed: lpddr4x has low power consumption and slow speed, while lpddr5 has higher power consumption but provides faster data transmission speed.
2. Difference in bandwidth capacity: lpddr4x provides low memory bandwidth and low data transmission efficiency, while the new technology of lpddr5 can provide higher memory bandwidth, thus improving data transmission efficiency.
