Samsung Semiconductor proposed an LPDDR4 variant that it called LPDDR4X. [22]: 11 LPDDR4X is identical to LPDDR4 except additional power is saved by reducing the I/O voltage (Vddq) from 1.1 V to 0.6 V. On 9 January 2017, SK Hynix announced 8 and 16 GB LPDDR4X packages. [23] [24] JEDEC published the LPDDR4X standard on 8 March 2017. [25]
Because power consumption increases with speed, the reduced voltage allows higher speed operation without unreasonable power and cooling requirements. DDR4 RAM operates at a voltage of 1.2 V and supports frequencies between 800 and 1600 MHz (DDR4-1600 through DDR4-3200).
The electrical interface for UFS uses the M-PHY, [6] developed by the MIPI Alliance, a high-speed serial interface targeting 2.9 Gbit/s per lane with up-scalability to 5.8 Gbit/s per lane. [ 7 ] [ 8 ] UFS implements a full-duplex serial LVDS interface that scales better to higher bandwidths than the 8-lane parallel and half-duplex interface of ...
DDR5, DDR4, LPDDR5, and LPDDR4X memory support Up to DDR5-4800; Up to DDR4-3200; Up to LPDDR5-5200; Up to LPDDR4x-4267; XMP 3.0 [1] Dynamic Memory Boost [1] Integrated Thunderbolt 4 and WiFi 6E support [26] Supported via PCH on desktop processors; Directly supported by CPU on non-HX mobile processors
Each test measures the data rate for the download direction, i.e. from the server to the user computer, and the upload data rate, i.e. from the user's computer to the server. The tests are performed within the user's web browser or within mobile apps. As of 17 February 2024, over 52.3 billion Internet speed tests have been completed. [8]
Apple M1 is a series of ARM-based system-on-a-chip (SoC) designed by Apple Inc., launched 2020 to 2022.It is part of the Apple silicon series, as a central processing unit (CPU) and graphics processing unit (GPU) for its Mac desktops and notebooks, and the iPad Pro and iPad Air tablets. [4]
On November 11, 2020 Intel launched the H3C XG310 data center GPU consisting of four DG1 GPUs with 32 GB of LPDDR4X memory on a single-slot PCIe card. [50] [51] Each GPU is connected to 8 GB of memory over a 128-bit bus and the card uses a PCIe 3.0 x16 connection to the rest of the system. The GPUs use the Xe-LP (Gen 12.1) architecture.
Adreno is an integrated graphics processing unit (GPU) within Qualcomm's Snapdragon applications processors, that was jointly developed by ATI Technologies in conjunction with Qualcomm's preexisting "QShader" GPU architecture, and coalesced into a single family of GPUs that rebranded as Adreno in 2008, just prior to AMD's mobile division being sold to Qualcomm in January 2009 for $65M.
