The 8088 has a external 8 bits bus. The performance improvement hardware 16 bits ALU is neglected by the slower memory access.
And that memory access was also the reason a 6502 carefully programmed will have better performance than a 8088 with 5x the clock speed. The first 256 bytes (0 pages) had better access performance.
