• Bobcat-based CPU
• Evergreen/VLIW5-based GPU (branded Radeon HD 6000 series and Radeon HD 7000 series)
• Northbridge
• PCIe support.
• DDR3 SDRAM memory controller to arbitrate between coherent and non-coherent memory requests. The physical memory is partitioned between the GPU (up to 512 MB) and the CPU (the remainder).
• Unified Video Decoder (UVD)

The AMD Brazos platform was introduced on 4 January 2011, targeting the subnotebook, netbook and low power small form factor markets. It features the 9-watt AMD C-Series APU (codename: Ontario) for netbooks and low power devices as well as the 18-watt AMD E-Series APU (codename: Zacate) for mainstream and value notebooks, all-in-ones and small form factor desktops. Both APUs feature one or two Bobcat x86 cores and a Radeon Evergreen Series GPU with full DirectX11, DirectCompute and OpenCL support including UVD3 video acceleration for HD video including 1080p.

AMD expanded the Brazos platform on 5 June 2011 with the announcement of the 5.9-watt AMD Z-Series APU (codename: Desna) designed for the Tablet market. The Desna APU is based on the 9-watt Ontario APU. Energy savings were achieved by lowering the CPU, GPU and northbridge voltages, reducing the idle clocks of the CPU and GPU as well as introducing a hardware thermal control mode. A bidirectional turbo core mode was also introduced.

AMD announced the Brazos-T platform on 9 October 2012. It comprised the 4.5-watt AMD Z-Series APU (codenamed Hondo) and the A55T Fusion Controller Hub (FCH), designed for the tablet computer market. The Hondo APU is a redesign of the Desna APU. AMD lowered energy use by optimizing the APU and FCH for tablet computers.

The Deccan platform including Krishna and Wichita APUs were cancelled in 2011. AMD had originally planned to release them in the second half 2012.

An AMD A4-5300 for desktop systems

An AMD A10-4600M for mobile systems

• Steamroller-based CPU with 2–4 cores
• Graphics Core Next 2nd Gen-based GPU with 192–512 shader processors
• 15–95 W thermal design power
• Fastest mobile processor of this series: AMD FX-7600P (35 W)
• Fastest desktop processor of this series: AMD A10-7850K (95 W)
• Socket FM2+ and Socket FP3
• Target segment desktop and mobile
• Heterogeneous System Architecture-enabled zero-copying through pointer passing

The third generation of the platform, codenamed Kaveri, was partly released on 14 January 2014. Kaveri contains up to four Steamroller CPU cores clocked to 3.9 GHz with a turbo mode of 4.1 GHz, up to a 512-core Graphics Core Next GPU, two decode units per module instead of one (which allows each core to decode four instructions per cycle instead of two), AMD TrueAudio, Mantle API, an on-chip ARM Cortex-A5 MPCore, and will release with a new socket, FM2+. Ian Cutress and Rahul Garg of Anandtech asserted that Kaveri represented the unified system-on-a-chip realization of AMD's acquisition of ATI. The performance of the 45 W A8-7600 Kaveri APU was found to be similar to that of the 100 W Richland part, leading to the claim that AMD made significant improvements in on-die graphics performance per watt; however, CPU performance was found to lag behind similarly specified Intel processors, a lag that was unlikely to be resolved in the Bulldozer family APUs. The A8-7600 component was delayed from a Q1 launch to an H1 launch because the Steamroller architecture components allegedly did not scale well at higher clock speeds.

AMD announced the release of the Kaveri APU for the mobile market on 4 June 2014 at Computex 2014, shortly after the accidental announcement on the AMD website on 26 May 2014. The announcement included components targeted at the standard voltage, low-voltage, and ultra-low voltage segments of the market. In early-access performance testing of a Kaveri prototype laptop, AnandTech found that the 35 W FX-7600P was competitive with the similarly priced 17 W Intel i7-4500U in synthetic CPU-focused benchmarks, and was significantly better than previous integrated GPU systems on GPU-focused benchmarks. Tom's Hardware reported the performance of the Kaveri FX-7600P against the 35 W Intel i7-4702MQ, finding that the i7-4702MQ was significantly better than the FX-7600P in synthetic CPU-focused benchmarks, whereas the FX-7600P was significantly better than the i7-4702MQ's Intel HD 4600 iGPU in the four games that could be tested in the time available to the team.
