Microsoft has yet to launch its next-generation DirectX 12 multimedia API, but AMD and Nvidia are both ready with hardware to support it.

For AMD, its Radeon HD 7000 and Radeon R200 series will support the API, while over at Nvidia support will come from the Fermi, Kepler and Maxwell generation of GeForce GPUs.
DirectX 12 isn't just a small tweak applied to the top of the existing DirectX 11 API; it's a big revision. It brings to the table a significant number of benefits, as listed by AMD:

  • Better use of multi-core CPUs
  • More on-screen detail
  • Higher min/max/average framerates
  • Smoother gameplay
  • More efficient use of GPU hardware
  • Reduced System power draw
  • Allows for new game designs previously considered impossible due to restriction by older APIs
