How do the cores in an i.MX7Dual compare to an i.MX6ULL?

I'm particularly interested in double precision floating point performance. I've benchmarked a 528MHz i.MX6ULL and need more DP FLOPS. Can I expect a 1GHz i.MX7Dual to give me ~2x the DP FLOPS for each core?

 

I understand it may seem a strange question but I benchmarked a 1GHz TI Cortex-A8 part this week and that was significantly slower than the 528MHz i.MX6ULL for double precision MACs. Double the speed for integers but it seems it has a less capable Neon. ARM's documentation on the subject is quite dense.

 

So, before I buy yet another EVK ... Are each of the Cortex-A7 MPCores in an i.MX7Dual the same as the one in the i.MX6ULL?
