The A10-7870K is a 95W Kaveri APU which uses the FM2+ platform. It fills the pricepoint  left by the A10-7850K.

The A10-7870K has four Steamroller cores, 4 MB of L2 cache, and DDR3-2133 support.  It also has eight Radeon GPU GCN architecture based cores.

The A10-7870K has increased clock speeds over the A10-7850K it is now 3.9 GHz with a turbo frequency of 4.1 GHz.  The A10-7850K  was 3.7 GHz  boosted to 4.0 GHz

The GPU has  a 20 percent clock speed boost, from 720 MHz  to 866 MHz  over 512 shader processors, 32 TMUs and 8 ROPs.

AMD is pairing the ship against the Core i3-4370 which it conviently outperforms i3-4370 in CPU-heavy workloads such as PCMark 8, and completely kicking it to death in compute workloads like 3DMark.  This is mostly because of AMD’s better GPU performance.

The A10-7870K goes on sale today for $137, which is less than Intel's $150 Core i3-4370. AMD says that the APU delivers "Core i5 performance at Core i3 pricing.
