No, benchmarks show the mobile i7 in last year's MBP as faster 
than your old desktop core i5, so the iPad Pro is faster than 
your desktop. :P Of course, the TDP of your desktop i5 is twice 
the mobile i7 and almost 10 times the A12X in the new iPad Pro, 
so Apple completely blows away Intel on the 
performance-to-power-dissipation ratio.

There are 64-bit ARM workstations and server cores if you want
