what's the benefit of capability1.3 in coalesced memory access, compared to capability1.1

Accelerated Computing CUDA CUDA Programming and Performance

I’m new in cuda and,

My graphic card is gtx285 and the capability is 1.3(I think so, because I tried devicequery and it said the major reversion is 1 and the minor reversion is 3)

So if I want a coalesced memory access, in 1.3, should the pattern that the alignment of the data address and the same index of the threadidx and data relative-position be matched?

and how about the bank?

thanks

There is no coalesced and non-coalesced anymore with CC 1.3, it is now the number of memory transactions that counts. Having said that: if your memory accesses are coalesced on 1.0/1.1 hardware, then you also have the minimum amount of memory transactions
