Samsungs Exynos 8895 features custom CPU cores, first 10nm chip to market

Mobile World Congress doesn’t start for a few days, but Samsung has already jumped the gun to announce its own SoC. The Exynos 8895 will be the first 10nm chip produced in commercial volume, and it’ll feature a new custom CPU core of Samsung’s own design.

We’ve discussed Samsung’s M1 processor before, since that chip featured in some versions of the Galaxy S7, but there’s no word on what kind of features or capabilities Samsung has baked into the core. With this version of the core following hard on the heels of the previous, it seems safe to assume it’ll be a tweaked version of the M1 core, optimized for better performance and the 10nm process, but not a new architecture or huge overhaul of the CPU core.

Samsung has previously described its 10nm LPE process as offering either 27% improved performance or 40% reduced power, and the Exynos 8895 is still an eight-core design with four Cortex-A53s and four Samsung M2 CPUs running at an unknown clock speed.

The Samsung M1 is a wide design capable of decoding four instructions per cycle. It can retire and rename four micro-ops per cycle and can issue up to seven micro-ops per cycle. Its L2 cache is 2MB (split between cores), with a 22 cycle latency — relatively high, as such things go, but this likely saves power compared with a more aggressive design.
