the introduction of Trinity-based APUs in 2012, which replaced the K10 cores in the APU with Bulldozer-derived cores. Family 11h and 12h derivatives Turion X2 Ultra Family 11h The Family 11h microarchitecture was a mixture of both K8 and K10 designs with lower power consumption for laptop that was marketed as Turion X2 Ultra and was later replaced by completely K10-based designs. Fusion Family 12h The Family 12h microarchitecture is a derivative of the K10 design: Both CPU and GPU were re-used to avoid complexity and risk Distinct Software and Physical integration makes Fusion (APU) microarchitectures different Power-saving improvements including clock gating Improvements to hardware pre-fetcher Redesigned memory controller 1MB L2 cache per core No L3 cache Two new buses for on-die GPU to access memory (called Onion and Garlic interfaces) AMD Fusion Compute Link (Onion) – interfaces to CPU cache and coherent system memory (see cache coherence) Radeon Memory Bus (Garlic) – dedicated non-coherent interface connected directly to memory Media discussions Note: These media discussions are listed in ascending date of publication.
