It's a comprehensive batch of tests that puts your entire system -- CPU, RAM, HDD, GPU, even PSU -- through the wringer. S&M v.1.90 will test everything in your CPU, including the integrity of its L1 and L2 caches, the integer calculator, and the Floating Point Unit calculator. The FPU test, in particular, generates the absolute highest temps that I've ever observed in a stress test (for both Intels and AMDs, mind you; it's on a par with Intel's TAT). The difference in peak load temperatures generated is, on average, five degrees Centigrade higher on S&M than on any other stress test I know of. This is one reason why I deem it the ultimate stress test, as well; it will really tell you how good your thermals are.
There's a four-stage RAM test, though I cannot be more precise in the description of the tests. This is one test, though, which exposed a weakness in some parts I used to have. It literally broke
a set of Corsair DDR500s I used to have; on the other hand, this same RAM kit never was able to run at advertised specs fresh from the box, so it had definite weaknesses and defects from the factory. S&M just pushed it over the edge.
The program tests your PSU, as well, by incorporating a GPU load test. I've never ever failed this test, so I cannot describe what would constitute a failure trigger. I suspect, though, that it will detect a severe load voltage drop and therefore indicate a test failure.
There is also a HDD test with three stages: "Interface;" "Surface;" and "Positioner."
Clearly, a comprehensive testing suite.
I've attached some screen shots, too, so you can have a look at it. The CPU test screens were taken a little over a month ago, but the RAM and HDD test screens were taken just now (which would explain the different desktop). These were done on my gaming rig, FYI.
Hope this helps!
