Puma is a low-power SoC microarchitecture by AMD. It succeeds Jaguar, targets the same market and belongs to the same AMD architecture family 16h. The Beema line of Jaguars processors are aimed at low-power notebooks, and Mullins are targeting the tablet sector.

Design[edit]

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

Instruction set support[edit]

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]
