How is Vulkan similar to Mantle and what are the differences?

The original proposal for Vulkan was basically a cleaned up version of Mantle. AMD got the conversation going, but over an 18-month period there were contributions from many other Khoronos members. Some are small tweaks and others are major features. For example, render pass was never in Mantle, yet it’s a core part of Vulkan now.

Some of the API names are the same, but it is a significant update. There are some very important differences and enhancements, and Vulkan is cross-vendor, cross-platform, so we’ve landed in a really good place. Overall Vulkan is truly a better API.
