Compared to the AllWinner H5, the RK3328 adds USB 3.0, HDMI 2.0a with 4K60p video decoding and DDR4/LPDDR3 memory support. Remaining features are on or almost on parity with the AllWinner H5, although the RK3328 has a weaker GPU and can only encode video at 30fps, whereas the H5 can encode at 60p, both limited to 1080p.
