MSI’s business & productivity laptop comes with a charming ultra-thin design and the perfect balance between performance and battery life. LPDDR4x memory is actually a part that can’t be ignored. Here’re the reasons how LPDDR4x can achieve the demands of this series of laptops.
What’s LPDDR4x Memory
LPDDR memory was designed for mobile devices to ensure powerful computing, high-resolution video, larger displays with more pixels, and an enhanced user experience, while maximizing battery life. LPDDR4x, the latest DDR memory for mobile applications, includes a number of features that enable SoC designer to reduce overall system power consumption. SO-DIMM memory (standard socketed memory) is often used in systems that have limited space, which include laptops, small-footprint personal computers, high-end upgradable office printers, and networking hardware such as routers and NAS devices. Systems using LPDDR3, LPDDR4 and LPDDR4x tend to have fewer memory chips on each bus and has shorter interconnects, in order to consume less power than regular SO-DIMM DDR4 systems.
LPDDR4x Memory Optimize Power Consumption
Both LPDDR4x and LPDDR4 are used on across a wide variety of devices and could lead to confusion due to their names are almost identical. In fact, LPDDR4x is not the next-generation memory of LPDDR4, but it can be regarded as the optimized power saving version of LPDDR4. Other LPDDR4x features are as same as LPDDR4, allowing extreme memory bandwidth to supply the heavy demands of multi-core CPU and GPU subsystems in modern smartphone SoCs.
↑ LPDDR4x voltage is 55% lower than LPDDR4, hence drains less power (lower is better)
LPDDR4x Memory for Laptop
How about laptop? Can it benefit from the LPDDR4x memory? The answer is yes, since the Intel 10th Gen. Core i7-1065G7 supports dual-channel LPDDR4x-3733 or DDR4-3200. However, the fastest LPDDR4x 4267 is only supported on the very recent Intel 11th Gen. Intel CPU, much faster than the LPDDR4x-3733 on the previous 10th Gen. platform.

Comparing LPDDR4x and SO-DIMM Memory
By offering a smaller package size and higher capacity without the socket module, the breakthrough of LPDDR4x memory is enabled the evolution of ultra-slim devices. The speed has also been increased from 3200MT/s to 4267MT/s (without OC) and it takes lesser space on-chip as single package can consist of up to 12GB of DRAM.
↑ LPDDR4x-4267 memory occupies smaller space by mounted on the motherboard and shorten the trace for better signal transmission
Here’s a soft reminder about the capacity of memory. MSI suggests that users choose the laptops with at least 16GB LPDDR4x memory because it is unable to do any futher memory upgrade. Just the operation system itself will consume around 2.7GB of memory after laptop is booted. MSI also suggests that optimization is often needed for the memory to keep the performance stable if the laptop has only 8GB memory or less. That’s the way how MSI’s business and productivity laptops with up to 32GB LPDDR4x memory to fulfill every demand in daily work and life.
Besides the size and power consumption, the performance is another key to know whether if the LPDDR4x SDARM is a good choice or not. The architecture of LPDDR4x memory supports dual-channel for laptops. In single-channel, data signal traveled a long distance from memory array to I/O, hence consumed more power to transmit data. On the other hand, dual channel provided a shorter distance which leads to reduced delay and power consumption to output data thus achieving higher bandwidth with low power consumption. That is also the reason the LPDDR4x-4267 has a much better AIDA 64 Cache & Memory benchmark result than DDR4-3200 single-channel.
↑ LPDDR4x-4267 memory has impressive performance in AIDA64 Cache & Memory Benchmark
Power-Performance Balance for Ultra-thin Laptop
All in all, the new LPDDR4x memory is the best solution for ultra-thin laptop since it has increased performance and also reduced the power consumption and comes with smaller the package size. That’s why MSI Summit E14, Prestige 14 Evo & Prestige 14 have chosen the LPDDR4x memory to build perfectly balanced ultra-thin and high-performance laptops for business users.
