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.
Design The Puma cores use the same microarchitecture as Jaguar, and inherits the design: Out-of-order execution and Speculative execution, up to 4 CPU cores Two-way integer execution Two-way 128-bit wide floating-point and packed integer execution Integer hardware divider Puma does not feature clustered multi-thread (CMT), meaning that there are no "modules" Puma does not feature Heterogeneous System Architecture or zero-copy 32 KiB instruction + 32 KiB data L1 cache per core 1–2 MiB unified L2 cache shared by two or four cores Integrated single channel memory controller supporting 64bit DDR3L 3.1 mm2 area per core
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.
Improvements over Jaguar 19% CPU core leakage reduction at 1.2V 38% GPU leakage reduction 500 mW reduction in memory controller power 200 mW reduction in display interface power Chassis temperature aware turbo boost Selective boosting according to application needs (intelligent boost) Support for ARM TrustZone via integrated Cortex-A5 processor Support for DDR3L-1866 memory
Puma+ AMD released a revision of the Puma microarchitecture, Puma+, which is integrated into the Carrizo-L APU platform.
