These were discussed at UDS: http://kernel.ubuntu.com/~cking/x32/Quantal-x32-power-memory-comparisons.ods comparing 64/64 64/32 32/32 kernel/userspace for various tasks, memory usage, power consumption, and duration where approporiate. What I can deduce from those is that 32-bit userspace definitely uses 15-20% less memory. power consumption was the same within 1% for most tests, but 10% and 4% worse on 32bit for 2 tests (no idea why).
