We ran the test rig through Futuremark’s latest system performance metric PCMark Vantage as well. This benchmark suite creates a host of different usage scenarios to simulate different types of workloads including High Definition TV and movie playback and manipulation, gaming, image editing and manipulation, music compression, communications, and productivity. We like the fact that most of the tests are multi-threaded as well, in order to exploit the additional resources offered by multi-core processors.
One thing to keep in mind when comparing PCMark Vantage results is that the benchmark's margin of error is fairly wide—we'd estimate 5-7 percent. Relevant factors include whether or not the hard drive was defragmented immediately prior to the run and whether Vantage was run immediately following OS+driver installation, or only after a full suite of tests and other benchmarks had been run.
The Lenovo M90z doesn't do badly for an all-in-one, but the newer ET2400 leverages its quad-cores and more powerful GPU to good effect. Both of these systems use conventional hard drives which explains why these results might be lower than those you see elsewhere on the site.
