History
Predecessor	Jaguar - Family 16h

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^[2]
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.^[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 the Puma microarchitecture, Puma+, which is integrated into the Carrizo-L APU platform.
