We've known for some time that publisher Electronic Arts has adopted the powerful Frostbite Engine tech from its Swedish subsidiary DICE, as the defacto technology that many of its upcoming non-sports titles, and according to comments from DICE Technical Director Johan Anderson, those titles number more than 15.
The number was casually offered in a Twitter response to a fan question about utilising the benefits of AMD's recently revealed Mantle API across Frostbite 3 games, to which Anderson replied "yes the plan is once Mantle in #BF4 is done it's part of Frostbite & Mostly 'out of the box' to use the rest of our 15+ games"
points out seven of EA's currently announced titles known to be in active development on Frostbite tech, which include Battlefield 4, Mirror’s Edge 2, Star Wars Battlefront, Need For Speed: Rivals, Dragon Age: Inquisition, Plants vs. Zombies: Garden Warfare, and the next Mass Effect game, then the upcoming free-to-play Command & Conquer game would make eight.
It seems unlikely that performance benefits from Mantle would be retroactively pushed out to older, Frostbite 2.0 engine games like Battlefield 3 and need for Speed: The Run, but DICE is also known to be working on a Frostbite GO engine tailored to mobile devices, so perhaps there'll be some mantle action there also.
DSO also notes another tweet
from Anderson that confirms that all of Frostbite 3 does not have any optimisations that work on Windows 8.1 and not Windows 8, so no rush for eager BF4 players to upgrade to Microsoft's latest OS update there.
