엥? 375는 neon 첨가! 370은 없어영~ 라고?!?!
The Armada 375 resembles the Armada 370, which has one of Marvell’s ARMv7-compatible PJ4 cores running at 1.2GHz. Although this home-grown CPU is clocked 20% faster than the 375’s Cortex-A9 cores, it lacks Neon extensions and has a less capable version of the VFP unit.
