Faster Performance and Improved Efficiency

Intel’s new Optane M15 series has been announced for 7th Gen and above Intel Core processor systems, and it becomes the first iteration to attach via your motherboard’s PCIe 3.0 x4 NVMe interface, with the previous M10 Series using just two PCIe lanes.

The M15 Series will be available as before in 16GB / 32GB / 64 GB modules and offers significant performance uplift compared to the M10 series with sequential and random read/write speed gains across the board, as well as reduced latency.

"The Intel Optane memory M15 features two extra PCIe lanes that enable higher throughput bandwidth for enhanced system acceleration and responsiveness. Intel Optane memory M15 also adds incremental NVMe features, improved low power states, and improved power state transitions—all of which enable a higher level of performance than its predecessor, Intel Optane memory M10."

Intel has worked on efficiency as well with the M15 series, and while active power with the largest module has risen from up to 3.5W to up to 5.5W, the M15 series offers improved power state transitions and low-power states, now with just <5mW Deep Sleep/L1.2 compared to 11mW from the M10 series.

The new Intel Optane Memory M15 will go on sale in mid-Q3.
