2014 saw the release of the first heterogeneous-system-architecture (HSA) enabled processor. The A10-7850K contained four of AMD’s new “Steamroller” cores (two modules), along with 8 GCN compute-capable cores. Together, they formed the foundation of the Kaveri APU. On July 31st, AMD released their second batch of APUs using the Kaveri architecture. While one of those APUs (the A8-7600) was announced in January and makes its retail appearance this summer, the other two are new additions to the Kaveri lineup: the single module/dual core A6-7400K, and the multiplier-locked, tuned for efficiency version of the A10-7850K, the A10-7800.

Sporting a configurable TDP and all of the Kaveri features (GCN graphics cores, Steamroller CPU cores, HSA, etc.), the A10-7800 which Benchmark Reviews will be looking at today sits right in between the A10-7850K and A10-7700K. What type of performance was AMD able to extract from this 65W APU? Read on to find out.

AMD_A10_7800_TopIn this review, I’ll mostly be concentrating on the performance of the A10-7800 and its Radeon R7 integrated GPU. I’ll include results at the 65W and 45W configurable TDP points, as well as an A10-7850K, A10-5800K and i5-4430 “analogue” (an i5-4670K clocked down to match i5-4430 specs). AMD’s marketing materials and pricing target the beginning of Intel’s i5 range, so we’ll take a look and see how the new A10-7800 compares.
