Bobcat is a microarchitecture created by AMD aimed at low-power/low-cost market.
It was revealed during a speech from AMD executive vice-president Henri Richard in Computex 2007 and was put into production Q1 2011. 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 Watts range and actively promoted the development of the simpler core with a target range of 1-10 Watts. 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. 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, detailing the specifications and advantages of extending x86 "everywhere".
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:
- 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
In February 2013, AMD detailed plans for a successor to Bobcat codenamed Jaguar.
