Jaguar, or Family 16h, is the codename for the next generation low-power SoC microarchitecture by AMD. It forms the basis for 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. In addition to the previous four product families, this microarchitecture also forms the basis for AMD's Semi-Custom Business Unit. Both the PlayStation 4 and the Xbox One use chips based on the Jaguar microarchitecture.[3]
Improvements over Bobcat
- Over 10% increase in clock frequency[4]
- Over 15% improvement in instructions per clock (IPC)[4]
- Added support for SSE4.1, SSE4.2, AES, CLMUL, MOVBE, AVX, F16C, and BMI1[4]
- Up to 4 CPU cores
- Up to 2 MB 16-way associative L2 shared cache for 4 cores
- Turbo Dock Technology
- FPU datapath width increased to 128 bit[4]
- Added hardware integer divider
- Enhanced cache prefetchers
- Doubled bandwidth of load/store units
- C6 and CC6 low power states[4]
- 3.1 mm2 area per core
- Integrated Fusion Controller Hub (FCH)
Design
- 32 KiB instruction + 32 KiB data L1 cache per core
- 1 MiB unified L2 cache shared by two cores
- 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[5]
- Server processors support 2 DDR3 DIMMS in one channel at frequencies up to 1600 MHz with ECC[6]
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]
