And even those numbers on the front page are out of date :) (we're even faster now: https://github.com/soumith/convnet-benchmarks/pull/96, which is from a few weeks ago.)

The field is moving quickly enough that many published benchmarks are stale within 3 months, and it's a lot of hard work to maintain up to date benchmarks, given how many frameworks there are. Also there are performance/memory/scalability/flexibility tradeoffs everywhere, so it's hard to capture everything in one number without a tremendous number of caveats.
