The AMD Jaguar Family 16h is a low-power microarchitecture designed by AMD, and used in APUs succeeding the Bobcat Family microarchitecture in 2013 and being succeeded by AMD's Puma architecture in 2014. It is two-way superscalar and capable of out of order execution. It is used in AMD's Semi-Custom Business Unit as a design for custom processors and is used by AMD in four product families: Kabini aimed at notebooks and mini PCs, Temash aimed at tablets, Kyoto aimed at micro-servers, and the G-Series aimed at embedded applications. Both the PlayStation 4 and the Xbox One use chips based on the Jaguar microarchitecture, with more powerful GPUs than AMD sells in its own commercially available Jaguar APUs.^[2]

Design

• 32 KiB instruction + 32 KiB data L1 cache per core, L1 cache includes parity error detection
• 16 way, 1-2 MiB unified L2 cache shared by two or four cores, L2 cache is protected from errors by the use of error correcting code
• Out-of-order execution and Speculative execution
• Integrated memory controller
• Two-way integer execution
• Two-way 128-bit wide floating-point and packed integer execution
• Integer hardware divider
• Consumer processors support 2 DDR3L DIMMs in one channel at frequencies up to 1600 MHz^[3]
• Server processors support 2 DDR3 DIMMS in one channel at frequencies up to 1600 MHz with ECC^[4]
• As a SoC (not just an APU) it integrates Fusion controller hub
• Jaguar does not feature clustered multi-thread (CMT), meaning that execution resources are not shared between cores

Instruction set support

The Jaguar 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 Bobcat

• Over 10% increase in clock frequency^[5]
• Over 15% improvement in instructions per clock (IPC)^[5]
• Added support for SSE4.1, SSE4.2, AES, CLMUL, MOVBE, AVX, F16C, and BMI1^[5]
• Up to 4 CPU cores
• L2 cache is shared between cores
• FPU datapath width increased to 128 bit^[5]
• Added hardware integer divider
• Enhanced cache prefetchers
• Doubled bandwidth of load-store units
• C6 and CC6 low power states with lower entry and exit latency^[5]
• Smaller, 3.1 mm² area per core
• Integrated Fusion controller hub (FCH)
• Video Coding Engine

Processors

Consoles

• ² Pixel fillrate is calculated as the number of ROPs multiplied by the base core clock speed.
• ³ Texture fillrate is calculated as the number of TMUs multiplied by the base core clock speed.
