CAMM2 vs. DDR5 DIMM and What’s Next After RAM

The world of computer memory is undergoing an exciting transformation with the arrival of CAMM2 (Compression Attached Memory Module) technology. Developed to address the needs of both laptops and desktops, CAMM2 is positioned as a promising alternative to traditional DDR5 DIMMs. Recently, MSI tested Kingston’s DDR5-7200 C38 CAMM2 memory against conventional DDR5 DIMMs, offering a detailed comparison of their performance. Beyond these benchmarks, exploring what comes next after RAM reveals a broader picture of the evolving technology landscape.

Benchmark Performance: CAMM2 vs. DDR5 DIMM

MSI’s recent evaluation has provided some intriguing insights into how CAMM2 compares to DDR5 DIMMs:

• Memory Read Speed: CAMM2 clocked in at 105.83 GB/s, just shy of DDR5 DIMMs’ 106.76 GB/s.
• Memory Write Speed: Here, DDR5 DIMMs had a clear advantage, hitting 91,821 MB/s compared to CAMM2’s 88,637 MB/s.
• Memory Copy Speed: Both technologies performed nearly identically, with CAMM2 at 94,772 MB/s and DDR5 DIMMs at 94,619 MB/s.
• Memory Latency: CAMM2 had a latency of 66.3 ns, slightly higher than the DDR5 DIMM’s 65.3 ns.

Overall, while DDR5 DIMMs exhibit a slight edge in write speeds, CAMM2 performs comparably in most other areas, highlighting its competitive stance in the memory market.

CAMM2 Design and Benefits

CAMM2’s design introduces several key benefits over traditional memory modules:

• Reduced Z-Height: The thinner profile of CAMM2 modules makes them a great fit for ultra-thin laptops and compact desktop setups.
• Single Module Dual-Channel Configuration: CAMM2 can deliver dual-channel bandwidth with just one module, simplifying motherboard design and potentially lowering costs.
• Enhanced Capacity and Flexibility: CAMM2 supports higher capacities and various memory types like DDR5 and LPDDR5X, providing more options for manufacturers.
• Improved Stability and Thermal Management: The CAMM2’s compression connector mounts securely to an interposer on the motherboard, helping with stability and better thermal management by reducing vertical space.

Challenges and Adoption

Despite its advantages, CAMM2 faces some hurdles:

• Standardization and Adoption: CAMM2 needs widespread industry support from chipset makers and motherboard designers to become mainstream.
• Cost and Complexity: Initial CAMM2 modules may be pricier due to their innovative design and installation process.
• Motherboard Design Changes: The CAMM2 design requires some motherboard modifications, like relocating the 24-pin power connector, which might affect case compatibility and cable management.

Future Prospects

CAMM2 is a noteworthy advancement in memory technology, especially for thin laptops and high-performance desktops. Its innovative design could shape future hardware trends. The true measure of CAMM2’s success will depend on how quickly the industry can adopt and integrate this new technology.

As more manufacturers embrace CAMM2 and refine its design, we can expect broader implementation and potential performance gains. CAMM2’s ability to match DDR5 DIMMs while offering a glimpse into a more adaptable future for memory modules is promising.

What’s Next After RAM?

Looking ahead, the evolution of memory technology hints at some exciting developments:

• 3D XPoint Technology: This technology offers faster data access speeds and improved endurance compared to traditional NAND flash, potentially changing how we approach storage and memory expansion.
• MRAM (Magnetoresistive RAM): By using magnetic states for data storage, MRAM could offer high speeds and durability, possibly serving as an alternative to DRAM.
• ReRAM (Resistive RAM): With its potential for high speed, low power consumption, and non-volatility, ReRAM could revolutionize data storage.
• Neuromorphic Computing: Mimicking the human brain’s neural architecture, neuromorphic chips could enhance efficiency in tasks like pattern recognition and learning.
• Unified Memory Systems: Integrating various types of memory into a single architecture could optimize performance and power efficiency.

These advancements are set to drive the next wave of computing innovation. Staying updated on these developments will be crucial as they begin to reshape the future of technology.

Conclusion

The arrival of CAMM2 marks a significant milestone in memory technology, bringing a new form factor that promises enhanced performance, flexibility, and efficiency. While CAMM2 currently matches DDR5 DIMMs in several key areas, its future impact will depend on how quickly it is adopted and integrated into mainstream products.

As we look beyond RAM, emerging technologies like 3D XPoint, MRAM, and ReRAM, along with advancements in neuromorphic computing and unified memory systems, hold the potential to transform the computing landscape. As these technologies mature, they will likely play a pivotal role in shaping the future of our digital world.
