Hand-held gaming consoles based on notebook platforms (such as the Valve SteamDeck, ASUS ROG Ally, and the MSI Claw) are one of the fastest growing segments in the PC gaming market. The form-factor of such systems has created a demand for M.2 2230 NVMe SSDs. Almost all vendors have a play in this market, and even Micron has OEM SSDs (such as the Micron 2400, 2550, and 2500 series) in this form-factor. Crucial has strangely not had an offering with its own brand name to target this segment, but that changes today with the launch of the Crucial P310 NVMe SSD.
The Crucial P310 is a family of M.2 2230 PCIe Gen4 NVMe SSDs boasting class-leading read/write speeds of 7.1 GBps and 6 GBps. The family currently has two capacity points - 1 TB and 2 TB. Micron claims that the use of its 232L 3D NAND and Phison's latest E27T DRAM-less controller (fabricated in TSMC's 12nm process) help in reducing power consumption under active use compared to the competition - directly translating to better battery life for the primary use-case involving gaming handheld consoles.
Based on the specifications, it appears that the drives are using 232L 3D QLC. Compared to the recently-released Micron 2550 SSD series in the same form-factor, a swap in the controller has enabled some improvements in both power efficiency and performance. The other specifications are summarized in the table below.
| Crucial P310 SSD Specifications | ||
| Capacity | 2 TB | 1 TB |
| Controller | Phison E27T (DRAM-less) | |
| NAND Flash | Micron 232L 3D QLC NAND | |
| Form-Factor, Interface | Single-Sided M.2-2230 PCIe 4.0 x4, NVMe |
|
| Sequential Read | 7100 MB/s | |
| Sequential Write | 6000 MB/s | |
| Random Read IOPS | 1 M | |
| Random Write IOPS | 1.2 M | |
| SLC Caching | Yes | |
| TCG Pyrite Encryption | Yes | |
| Warranty | 5 Years | |
| Write Endurance | 440 TBW 0.12 DWPD |
220 TBW 0.12 DWPD |
| MSRP | $215 | $115 |
The power efficiency, cost, and capacity points are plus points for the Crucial P310 family. However, the endurance ratings are quite low. Gaming workloads are inherently read-heavy, and this may not be a concern for the average consumer. However, a 0.12 DWPD rating may turn out to be a negative aspect when compared against the competition's 0.33 DWPD offerings in the same segment.
StorageAs Qualcomm's exclusivity for Arm-powered processors for Windows PCs is reportedly coming to its end, other chipmakers are getting ready to offer their Arm-based system-on-chips for Windows computers. And, according to a new report from Reuters, MediaTek will be among the companies jumping into the Windows-on-Arm field, with plans to launch their first PC processor late next year.
MediaTek's system-on-chip for Windows PCs will rely on Arm's 'ready-made designs,' according to Reuters. Which in turn hints that MediaTek would be using Arm's compute sub-system (CSS) for client PCs, a building block designed to significantly speed up development of SoCs.
With the vauge nature of the Reuters report, however, which version of Arm's IP MediaTek might be using remains unclear, and the answer to that will largely hinge on timing. Arm refreshes its client cores and IP offerings yearly – typically announcing them to the public in May – with finished chips rolling out as early as later in the year. So depending on just how late in the year MediaTek is planning to launch their chip, the company has a large enough window to potentially use either the current 2024 client designs, or next year's 2025 designs.
For reference, Arm's 2024 CSS for client systems is quite powerful on its own. It includes two ultra-high-performance Arm Cortex-X925 cores (each with up to 3MB L2 cache and clock speeds over 3.60 GHz, supporting SVE and SVE2), four high-performance Cortex-A725 cores, two energy-efficient Cortex-A520 cores, and an Immortalis-G925 graphics processor. And, of course, MediaTek has the expertise to skip Arm's CSS and build their own bespoke designs as well, if that's what they'd prefer.
Overall, the latest client designs from Arm can accommodate up to 14 CPU cores – Arm intentionally leaves headroom for designs to be scaled-up for laptops – which would make for quite a formidable chip. But the PC SoC market has no shortage of capable contenders with their own designs; besides Qualcomm's Snapdragon X processors, MediaTek would also be going up against the latest designs from Intel and AMD. All of whom are planning to make big plays for the mobile PC market in the next several months. So MediaTek will need to make a serious effort if their effort to jump into the PC SoC market are to succeed.
Since 2016, Microsoft has partnered with Qualcomm to bring Arm's processor architecture, which is widely used in smartphones, to Windows PCs. Qualcomm has an exclusive agreement to supply these chips for the next several months (the exact timing remains unclear), after which other designers like MediaTek can enter the market. Qualcomm, for its part, has benefited greatly from collaborating with Microsoft, so it will be interesting to see if Microsoft extends a similar hand out to other Arm chip makers.
Ultimately, the market for Arm PC SoCs has the potential to get crowded quickly. According to previous reports from Reuters, both AMD and NVIDIA are also developing Arm-based chips for Windows. So if all of those projects come to fruition, there could potentially be several Arm SoCs available to PC manufacturers around the same time. All of which would be a massive change from the past 20 years of the PC, where Intel and AMD have been the entire market.
Both MediaTek and Microsoft have declined to comment on the ongoing developments, the news agency states.
CPUsAs LPCAMM2 adoption begins, the first retail memory modules are finally starting to hit the retail market, courtesy of Micron. The memory manufacturer has begun selling their LPDDR5X-based LPCAMM2 memory modules under their in-house Crucial brand, making them available on the latter's storefront. Timed to coincide with the release of Lenovo's ThinkPad P1 Gen 7 laptop – the first retail laptop designed to use the memory modules – this marks the de facto start of the eagerly-awaited modular LPDDR5X memory era.
Micron's Low Power Compression Attached Memory Module 2 (LPCAMM2) modules are available in capacities of 32 GB and 64 GB. These are dual-channel modules that feature a 128-bit wide interface, and are based around LPDDR5X memory running at data rates up to 7500 MT/s. This gives a single LPCAMM2 a peak bandwidth of 120 GB/s. Micron is not disclosing the latencies of its LPCAMM2 memory modules, but it says that high data transfer rates of LPDDR5X compensate for the extended timings.
Micron says that LPDDR5X memory offers significantly lower power consumption, with active power per 64-bit bus being 43-58% lower than DDR5 at the same speed, and standby power up to 80% lower. Meanwhile, similar to DDR5 modules, LPCAMM2 modules include a power management IC and voltage regulating circuitry, which provides module manufacturers additional opportunities to reduce power consumption of their products.

It's worth noting, however, that at least for the first generation of LPCAMM2 modules, system vendors will need to pick between modularity and performance. While soldered-down LPDDR5X memory is available at speeds up to 8533 MT/sec – and with 9600 MT/sec on the horizon – the fastest LPCAMM2 modules planned for this year by both Micron and rival Samsung will be running at 7500 MT/sec. So vendors will have to choose between the flexibility of offering modular LPDDR5X, or the higher bandwidth (and space savings) offered by soldering down their memory.
Micron, for its part, is projecting that 9600 MT/sec LPCAMM2 modules will be available by 2026. Though it's all but certain that faster memory will also be avaialble in the same timeframe.
Micron's Crucial LPDDR5X 32 GB module costs $174.99, whereas a 64 GB module costs $329.99.
MemoryThe CXL consortium has had a regular presence at FMS (which rechristened itself from 'Flash Memory Summit' to the 'Future of Memory and Storage' this year). Back at FMS 2022, the company had announced v3.0 of the CXL specifications. This was followed by CXL 3.1's introduction at Supercomputing 2023. Having started off as a host to device interconnect standard, it had slowly subsumed other competing standards such as OpenCAPI and Gen-Z. As a result, the specifications started to encompass a wide variety of use-cases by building a protocol on top of the the ubiquitous PCIe expansion bus. The CXL consortium comprises of heavyweights such as AMD and Intel, as well as a large number of startup companies attempting to play in different segments on the device side. At FMS 2024, CXL had a prime position in the booth demos of many vendors.
The migration of server platforms from DDR4 to DDR5, along with the rise of workloads demanding large RAM capacity (but not particularly sensitive to either memory bandwidth or latency), has opened up memory expansion modules as one of the first set of widely available CXL devices. Over the last couple of years, we have had product announcements from Samsung and Micron in this area.
At FMS 2024, SK hynix was showing off their DDR5-based CMM-DDR5 CXL memory module with a 128 GB capacity. The company was also detailing their associated Heterogeneous Memory Software Development Kit (HMSDK) - a set of libraries and tools at both the kernel and user levels aimed at increasing the ease of use of CXL memory. This is achieved in part by considering the memory pyramid / hierarchy and relocating the data between the server's main memory (DRAM) and the CXL device based on usage frequency.
The CMM-DDR5 CXL memory module comes in the SDFF form-factor (E3.S 2T) with a PCIe 3.0 x8 host interface. The internal memory is based on 1α technology DRAM, and the device promises DDR5-class bandwidth and latency within a single NUMA hop. As these memory modules are meant to be used in datacenters and enterprises, the firmware includes features for RAS (reliability, availability, and serviceability) along with secure boot and other management features.
SK hynix was also demonstrating Niagara 2.0 - a hardware solution (currently based on FPGAs) to enable memory pooling and sharing - i.e, connecting multiple CXL memories to allow different hosts (CPUs and GPUs) to optimally share their capacity. The previous version only allowed capacity sharing, but the latest version enables sharing of data also. SK hynix had presented these solutions at the CXL DevCon 2024 earlier this year, but some progress seems to have been made in finalizing the specifications of the CMM-DDR5 at FMS 2024.
Micron had unveiled the CZ120 CXL Memory Expansion Module last year based on the Microchip SMC 2000 series CXL memory controller. At FMS 2024, Micron and Microchip had a demonstration of the module on a Granite Rapids server.
Additional insights into the SMC 2000 controller were also provided.
The CXL memory controller also incorporates DRAM die failure handling, and Microchip also provides diagnostics and debug tools to analyze failed modules. The memory controller also supports ECC, which forms part of the enterprise... Storage
