AMD A10-7850K Kaveri APU Processor Review

Article Index:
AMD Kaveri

Back in 2011, AMD released their APU line of processors. The APU features a processor and a “powerful” GPU on the same chip. The on-board GPU in the APU line is considerably less powerful than its desktop component counterpart, but more powerful than other comparable integrated graphic products. In the beginning 2014, AMD released the new Kaveri APU. The new APU consists of a quad core processor and a Radeon R7 built into the chip and a slew of other features that are designed to enhance the user experience while using an AMD Kaveri powered system. The ideal behind Kaveri is not just to build a processor, but a whole system that yields good performance yet doesn’t break the bank doing so.

AMD A10-7850K APU

The Kaveri APU rolls out with an updated version of the AMD’s Bulldozer architecture called Steamroller. The Steamroller architecture focuses more on improving the IPC of the APU. IPC is Instructions Per Clock cycle. IPC also determines how “fast” the CPU is. The Kaveri also uses a new manufacturing process that moves to 28nm. This allows the Kaveri to contain a Hawaii based GPU on board. The Kaveri APU contains 4 Steamroller cores and 8 GCN cores for a total of 12 “compute” cores in the A10-7850K.

The Kaveri APU introduces Heterogeneous System Architecture or HSA. With HSA the GPU and CPU are treated like equals. The CPU and GPU are able to work on the same data in the same memory space. Both have equal access to the memory space. HSA unlocks performance, as it is able to leverage the entire chip for processing functions. However, in order for the system to leverage HSA the applications need to up updated or written to use HSA. AMD expects HSA enabled applications in the wild over the next 12 to 18 months.

Since the Kaveri APU features a Hawaii based GPU, TrueAudio support is available for the applications and games that support it. TrueAudio is supposed to give more realistic audio while unloading the audio processing from the CPU.
