Snapdragon 8 Gen 4 May Adopt LPDDR6; Apple A18 Pro to Likely Feature LPDDR5T

The upcoming Snapdragon 8 Gen 4 mobile processor from Qualcomm could be a game-changer, packing potentially faster memory than its competitors. According to a recent report, the chip might be one of the first to support a new type of memory called LPDDR6. This could give smartphones powered by the Snapdragon 8 Gen 4 an edge in performance, especially for tasks involving artificial intelligence (AI).

LPDDR6 vs. LPDDR5T: A Battle of Memory Speeds

LPDDR stands for Low-Power Double Data Rate, a type of memory specifically designed for mobile devices. The number following LPDDR (like 5 or 6) indicates the generation, with each new generation offering improvements in speed and efficiency. LPDDR6 is expected to be significantly faster than the current LPDDR5 standard, allowing data to flow more quickly between the processor and memory.

Here's a quick breakdown:
  • LPDDR6: Faster speeds, potentially better suited for demanding AI tasks on smartphones. (Availability might be limited in 2024)
  • LPDDR5T: Currently the fastest available RAM in smartphones, offering speeds of up to 9.6 Gbps.

Apple's A18 Pro Likely Sticking with LPDDR5T:

Reports suggest Apple's upcoming A18 Pro chip, expected to power the next iPhone, might rely on the tried-and-tested LPDDR5T memory. However, there are rumors that Apple is exploring alternative solutions for on-device AI tasks, such as storing large language models (LLMs) on NAND flash memory. This could potentially allow iPhones with less RAM to compete with devices boasting faster memory.

Uncertainly Surrounds LPDDR6 Availability:

While LPDDR6 promises better performance, there are concerns about its mass production this year. The report suggests there might be challenges that could delay widespread availability until 2025. This means even if Qualcomm integrates LPDDR6 into the Snapdragon 8 Gen 4, it might not be a common feature across all devices using the chip.

Final Thoughts:

The battle for mobile supremacy continues on the memory front. Qualcomm's rumored adoption of LPDDR6 could be a significant leap forward, particularly for AI applications. However, with production hurdles and Apple's potential alternative solutions, it's still unclear which approach will reign supreme. Consumers will likely have to wait until the official launch of these new chipsets to see how this memory race plays out.
