There are many SPs in device, are they different? Are they all generic?

Hello Forum,
There are many SPs on the device, is there any difference between these SPs?
For example, one part dedicated to texture-related tasks, another part dedicated to 8-bit data, another part dedicated to 16-bit data, etc.? Or, are all SPs the same, all generic?

There are many (more than 2) types of functional units in a SM. A functional unit is designed to handle certain types of instructions. For example the LSU (Load/Store Unit) is a functional unit that handles, you guessed it, load and store instructions.

A SP is a functional unit that handles single-precision floating point add, multiply, and multiply-add instructions.

Given that definition, there is no functional difference between SPs. There are certainly functional differences between functional units of different types (e.g. between a LSU and a SP).

Given this definition, there are presumably other functional units (you may also see this referred to as “pipes” in the profiler terminology) that handle instructions that target, for example, double-precision floating point, or 16-bit floating point, or integer ops, etc.

Some of this is evident by reading any of the architecture whitepapers.

Thanks for your reply! This is very helpful for me!
