Puma (microarchitecture)

The Puma Family 16h is a low-power microarchitecture by AMD for its APUs. It succeeds the Jaguar as a second-generation version, targets the same market, and belongs to the same AMD architecture Family 16h. The Beema line of processors are aimed at low-power notebooks, and Mullins are targeting the tablet sector.

This article is about the microarchitecture. For the 2008 mobile platform, see AMD mobile platform § Puma platform (2008).

Design

The Puma cores use the same microarchitecture as Jaguar, and inherits the design:

Instruction set support

Like Jaguar, the Puma core has support for the following instruction sets and instructions: MMX, SSE, SSE2, SSE3, SSSE3, SSE4a, SSE4.1, SSE4.2, AVX, F16C, CLMUL, AES, BMI1, MOVBE (Move Big-Endian instruction), XSAVE/XSAVEOPT, ABM (POPCNT/LZCNT), and AMD-V.[1]

Improvements over Jaguar
  • 19% CPU core leakage reduction at 1.2V[3]
  • 38% GPU leakage reduction
  • 500 mW reduction in memory controller power
  • 200 mW reduction in display interface power
  • Chassis temperature aware turbo boost[4]
  • Selective boosting according to application needs (intelligent boost)
  • Support for ARM TrustZone via integrated Cortex-A5 processor
  • Support for DDR3L-1866 memory[5]

Puma+

AMD released a revision of Puma core, Puma+, as a part of the Carrizo-L platform in 2015. The differences in the CPU microarchitecture are unclear. Puma+ featured 2 or 4 cores up to 2.5GHz and required the newer FP4 socket.[6]
