The benchmarks that Thomas ran a couple of days ago for his story Windows 8: Does AMD's Bulldozer Architecture Benefit? did not include Futuremark's synthetic PCMark and 3DMark tests. After all, although they're based on real-world Windows applications, there are times where we simply cannot reconcile the numbers we generate with these tests to our application testing.
What PCMark does do, however, is give us a more holistic look at system performance, whereas our application-based metrics generally isolate the CPU. With that in mind, let's have a look at how one machine handles two operating systems.
For the most part, we see similar performance in both operating systems. The only exception is the Physics sub-test, where Windows 7 surprises us with a win. This benchmark is decidedly threaded, and there really isn't any good reason we can come up with for this difference to exist.
Again, it's not necessarily clear why the results pan out the way they do, with Windows 8 claiming big leads in the overall benchmark and particularly the Computation sub-test. However, that result (based on a very processor-heavy workload) seems to contradict the 3DMark Physics sub-test (also very CPU-dependent). Could the difference be in PCMark's handling of Quick Sync technology, which we've seen in the past affects this benchmarks results heavily?
