Hello FRANK CHU, 
 The ADAU1452WBCPZ is a 294.912MHz (commonly called as 300MHz) clock speed variant. It will have 6144 instructions per sample period at 48KHz sample rate. whereas the ADAU1452WBCPZ150 is slower grade which has 147.456MHz (commonly called as 150MHz variant) system clock. So, the total number of MIPS will be halved. (It will have 3072 MIPS per sample period at 48KHz sample rate). The memory and all other resources will be exactly the same between these variants. 
 Regards, 
 Harish)
