高通骁龙865曝光:支持LPDDR5内存

4月11日消息,知名爆料人士Roland Quandt透露,内部型号为SM8250的高通下一代旗舰平台支持LPDDR5内存(高通骁龙855支持LPDDR4X内存),虽然高通暂未公布SM8250的最终命名,但是按照以往命名规则,SM8250应该会被命名为高通骁龙865(高通骁龙855内部型号为SM8150)。

LPDDR5是今年2月20日才公布的全新低功耗内存标准,相比LPDDR4的I/O速度从3200 MT/s 提升到6400 MT/s,实现了翻倍增长。如果匹配高端智能机常见的64位总线,每秒可以传送51.2GB数据;要是PC的128位总线,每秒可达到100GB。另外,LPDDR5还引入了链路ECC纠错,信号电压250mV,Vddq/Vdd2电压还是1.1V。

Roland Quandt称高通公司已经拥有搭载LPDDR5内存+骁龙865旗舰平台的样机,目前正在进行测试。遗憾的是,暂时还不清楚高通骁龙865旗舰平台的时钟频率及其它细节。

此外,Roland Quandt透露高通还有一款尚未发布的5G调制解调器SDM55,其代号为“Huracan”。它可能像X50一样通过外挂方式支持5G网络,另一种可能是骁龙865集成SDM55 5G调制解调器,实现对5G网络支持。如果为真,高通可能是第一个将5G基带集成到SoC的芯片商。

按照惯例,高通骁龙865旗舰平台预计会在2019年年底推出,2020年年初会有相应的终端上市,届时相信还很可能搭配最新的UFS3.0闪存,智能手机的读写性能将进一步提升,值得期待。
