Similar IPC but less performance. What does that mean?

Performance can be different if clock speeds are different.

The stranger part in the Helio X30’s design is that MediaTek decided to stick to using a four-core Cortex-A53 as well.

Another reason might be cost. A53's are much smaller than A73's, and I have a feeling that ARM charges more for its newer, more power-efficient A35 than the first-gen 64-bit A53's.

Also, the A53's are about 26% faster, per clock. Scale this by the clock speed ratio, and you get about 46% speed difference, between those cores.

BTW, consider that the dual-A73's should about 61% faster than the quad-A53 cluster. Of course, these are all very rough generalizations. NEON-heavy code will exhibit an even greater performance disparity between the A73's and the rest.
