Geekbench is the system benchmark that people salivate over. But I wonder how effective it is in representing real-world system performance for the kinds of workloads that people actually use. Geekbench measures things like CPU performance, memory access, and GPU performance. But, while these are important measurements, aren't there other tests which represent actual system usage with real world applications? Of course there are, by the bazillion. Every application vendor has their own suite of them. But which one is the one which is the best at representing what the real world user experience is for a new device like the 10.5 iPad? That would necessarily include things like transactions and testing of other capabilities which would extend beyond just the local platform. Networking and database come to mind. I know system performance measurement is often black magic. I've been involved in various testing efforts using things like TPC-D. That's a few levels above the iPad. But I'd rather to have a measurement of normal usages that typical users would do, than just a very granular benchmark that measures specific system component performance. The point is that while the CPU/GPU are important to system performance, there's a lot more to the user experience than just those, and it would be useful to know how this experience changes from one device version to the next.
