This is pretty much the same as for lpc16, though it only improves half as large prediction orders. With 128-bit vectors, this gives: C V old V new 1 69.2 181.5 95.5 2 107.7 180.7 95.2 3 145.5 180.0 103.5 4 183.0 179.2 102.7 5 220.7 178.5 128.0 6 257.7 194.0 127.5 7 294.5 193.7 126.7 8 331.0 193.0 126.5 Larger prediction orders see no significant changes at that size.
