AIM is an independent benchmark (like SPEC) that tests the overall performance
of a system, rather than just the CPU (as in SPEC). It is a better form of
benchmarking since it tests the entire system from the CPU, the system bus,
memory access, disk io, compilers upto the operating system. Real applications
uses all of these components and not just the CPU. However, if the application
is very CPU intensive then one would probably pay more attention to the SPEC
numbers. However, this does not take into account the fact that some of these
applications may have data swapping in and out of disk.

There are various suites of the benchmark:

AIM System Benchmark Suite-III
AIM Workstation Benchmark Suite-VI
AIM MultiUser Benchmark Suite-VII
AIM Independent Resource Benchmark Suite-IX

For example, the AIM Workstation Benchmark Suite-VI is a multi-threaded
benchmark that tests workstations under different application loads. It is a
set of 49 tests designed to apply specific application loads to a system
dedicated, typically, to single user workstation applications, and to measure
the systems multitasking performance.

Hope this helps.
