In 20 new models with two to four enhanced Steamroller B cores were released as Kaveri-refresh / Godavari. Top of the line model in 2014 was the quad-core A10-7850K APU, with a 3.7В GHz core frequency and 4В MB L2 cache, incorporating a 720В MHz GPU with 512 stream processors and over 856 GFLOPS of total processing power.

Desktop budget and mainstream markets (FM2+): The Trinity / Richland APU line was replaced in January 2014 by the Kaveri APU line, as the third generation of A10, A8, A6 and A4 series for the desktop market.

Main articles: 'Kaveri' desktop processors and 'Kaveri' mobile processors Features ДЄPU features table Processors APU lines Starting from May 2015 till March 2016 new APUs were launched as Kaveri-refresh (codenamed Godavari). In January 2014, the first Kaveri APUs became available. On 21 September 2011, leaked AMD slides indicated that this third generation of Bulldozer core was codenamed Steamroller. In 2011, AMD announced a third-generation Bulldozer-based line of processors for 2013, with Next Generation Bulldozer as the working title, using the 28В nm manufacturing process. Steamroller, the microarchitecture for CPUs, as well as Graphics Core Next, the microarchitecture for GPUs, are paired together in the APU lines to support features specified in Heterogeneous System Architecture. The final result was a 9% single-threaded IPC improvement, and 18% multi-threaded IPC improvement over Piledriver. Improvements center on independent instruction decoders for each core within a module, 25% more of the maximum width dispatches per thread, better instruction schedulers, improved perceptron branch predictor, larger and smarter caches, up to 30% fewer instruction cache misses, branch misprediction rate reduced by 20%, dynamically resizable L2 cache, micro-operations queue, more internal register resources and improved memory controller.ДЄMD estimated that these improvements will increase instructions per cycle (IPC) up to 30% compared to the first-generation Bulldozer core while maintaining Piledriver's high clock rates with decreased power consumption. The focus of Steamroller is for greater parallelism. Steamroller still features two-core modules found in Bulldozer and Piledriver designs called clustered multi-thread (CMT), meaning that one module is equal to a dual-core processor.
