This happened a little bit quietly last week – but Qualcomm has announced the first product that I’m aware of that will use LPDDR4 memory.
The processor is the Snapdragon 810 and you can read the press release here.
Naturally, these devices support the latest 64-bit mobile CPUs, native 4K video, image sensors up to 55MP, HDMI 1.4, Cat6 LTE, USB 3.0, Bluetooth 4.1, UFS Gear2, eMMC 5.0, SD 3.0 (UHS-1) and 802.11AC; all manufactured on 20nm process technology.
The memory performance is LPDDR4 1600MHz (assuming 3200Mbps data rate) with 2 64-bit channels giving an aggregate bandwidth of 25.6GByte/sec bandwidth according to the spec sheet here.
Qualcomm says that these products, the Snapdragon 810 and its sister product the Snapdragon 808, will “begin sampling in the second half of 2014 and expected to be available in commercial devices by the first half of 2015.”
Roll on, LPDDR4!
