MediaTek just unveiled its new Helio P65 chipset, with faster CPU cores as well as a beefed up NPU. It's not a strict upgrade over the older Helio P60 chipset (and the very similar P70), however. The MediaTek Helio P65's CPU features two Cortex-A75 and six Cortex-A55 cores. For comparison, the Helio P60/P70 used four A73 and four A53 (older generation, but a different proportion of big/little cores). According to ARM, the A75 is on average 22% faster than an A73. The A55 gets a similar 18% boost over the A53. So, expect higher single-threaded performance but a lower multi-threaded...
