Advanced Micro Devices on Tuesday unveiled additional details about its forthcoming code-named A-series “Kaveri” accelerated processing unit and also confirmed plans to launch them on January 14, 2014. As it appears, Kaveri will fully support all AMD’s latest technologies, including unified CPU-GPU memory, TrueAudio, DirectX 11.2, Mantle as well as HSA [heterogeneous system architecture].

 

AMD A-series “Kaveri” will feature two dual-core x86 Steamroller modules (two integer units per module), one FPU with two 128-bit FMACs, one MMX unit, Radeon R7 graphics processing unit with 512 stream processors (eight GCN compute units) as well as HUMA [heterogeneous unified memory architecture] shared memory controller. The total compute performance of AMD A10-7850K (3.7GHz x86 core clock-rate, 720MHz graphics engine frequency) “Kaveri” APU will be around 856GFLOPS, which is quite a lot.

The new series of APUs will support all the technologies that AMD introduced along with its latest family of graphics processors – which feature improved second-gen GCN architecture – including TrueAudio as well as DirectX 11.2 and Mantle application programming interfaces.

One of the key innovations of Kaveri is its HUMA shared memory controller that fetches data to both x86 and GCN processing units as well as acts like a dispatcher/hub. The unit supports heterogeneous queuing that defines how processors interact equally and enables uniform visibility into the entire memory space by both GPU and CPU.

Unlike in cases of previous-generation Fusion products, AMD will first release desktop versions of the accelerated processing units. The first bunch of such FM2+ chips will emerge on January 14, 2014, around two months from now. Later on Kaveri-like chips will be available inside notebooks, servers and embedded systems. Revenue shipments of the chips will begin this quarter.
