WordPress does not fall over under load, poorly configured Apache servers do that. When WP sites fall over in heavy traffic it's because they're on a small VPS or shared host, and Apache was allowed to spawn more processes than there is available memory. They only run into this condition when there's enough traffic that the baseline number of worker processes all get used up and new ones are spawned. It doesn't matter what's running on the server. I have done no special configuration and use no caching whatsoever, and my WordPress blog has been on HN's front page with hundreds of concurrent visits several times.

WordPress sites with a moderately complicated theme and several plugins can easily crumble under load even with an nginx+PHP-FPM setup. Yes, you can throw more hardware power at it, but that's true with Apache as well. If you're expecting a lot of visitors to a WordPress site, you will generally want to make sure you have a good cache.
