Benchmarks certainly can't tell the whole story. I originally had a ITX based i5 build upstairs to stream my mkvs to the upstairs TV. The Intel chip was supposed to have much better IPC than the Kaveri based APU alternatives and use far less power.
In practice however, the i5 had strange driver issues with its internal GPU. The driver would error whenever I tried to play older 2D PC games from my steam list. Also, I would randomly get a driver error that would kill .mkv playback on my PC. I would have to hard shutdown the software and go back in. No amount of updating the drivers from Intel resolved these issues.
I eventually scrapped that system an built an A10 replacement in a Wesena case. Ultra low profile HTPC chassis.
None of those issues surfaced in the APU build. I pretty much stick to AMD APUs for any builds without a discreet GPU after those experiences.
