The AMD Bobcat Family 14h is a microarchitecture created by AMD for its AMD APUs, aimed at a low-power/low-cost market.[1]
It was revealed during a speech from AMD executive vice-president Henri Richard in Computex 2007 and was put into production Q1 2011.[2] One of the major supporters was executive vice-president Mario A. Rivas who felt it was difficult to compete in the x86 market with a single core optimized for the 10–100 W range and actively promoted the development of the simpler core with a target range of 1–10 W. In addition, it was believed that the core could migrate into the hand-held space if the power consumption can be reduced to less than 1 W.
Bobcat cores are used together with GPU cores in accelerated processing units (APUs) under the "Fusion" brand.[3][4] A simplified architecture diagram was released at AMD's Analyst Day in November 2009. This is similar in concept with earlier AMD research in 2003,[5] detailing the specifications and advantages of extending x86 "everywhere".
Design
The Bobcat x86 CPU core design has since been completed and implemented in AMD APU processor products with a TDP of 18 W or less. The core is targeted at low-power markets like netbooks/nettops, ultra-portable laptops, consumer electronics and the embedded market. Since its launch, Bobcat-based CPUs have also been used by OEMs on larger laptops. Architecture specifics:[6]
- 64-bit core
- Out-of-order execution
- Advanced branch predictor
- Dual x86 instruction decoder
- 64-bit integer unit with two ALUs
- Floating-point unit with two 64-bit pipes
- Single channel 64-bit memory controller
- 32 KiB instruction + 32 KiB data L1 cache
- 512 KiB - 1 MiB L2 cache
- MMX, SSE, SSE2, SSE3, SSSE3, SSE4A, ABM
In February 2013, AMD detailed plans for a successor to Bobcat codenamed Jaguar.

- ↑ No APU models. Athlon X4 845 only.
- ↑ Unified shaders : texture mapping units : render output units
- ↑ To feed more than two displays, the additional panels must have native DisplayPort support.[14] Alternatively active DisplayPort-to-DVI/HDMI/VGA adapters can be employed.
- 1 2 To play protected video content, it also requires card, operating system, driver, and application support. A compatible HDCP display is also needed for this. HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup.
- 1 2 DRM (Direct Rendering Manager) is a component of the Linux kernel. Support in this table refers to the most current version.
