The '''AMD Bobcat Family 14h''' is a microarchitecture created by AMD for its AMD APUs, aimed at a low-power/low-cost market.<ref name=leon>{{cite web|title=List of AMD CPU microarchitectures - LeonStudio|url=http://leonstudio.org/p/165|website=LeonStudio - CodeFun|access-date=12 September 2015|date=3 August 2014|archive-date=26 September 2020|archive-url=https://web.archive.org/web/20200926092938/http://leonstudio.org/p/165|url-status=dead}}</ref>
It was revealed during a speech from AMD executive vice-president Henri Richard in Computex 2007 and was put into production Q1 2011.<ref>{{cite web | url=http://hothardware.com/News/AMD-FlipFlops-Llano-Later-Bobcat-Bounding-Forward/ | title=AMD Flip-Flops: Llano Later, Bobcat Bounding Forward | date=July 16, 2010 | first=Joel | last=Hruska | publisher=HotHardware | access-date=July 17, 2010 | archive-url=https://web.archive.org/web/20100721024445/http://hothardware.com/News/AMD%2DFlipFlops%2DLlano%2DLater%2DBobcat%2DBounding%2DForward/ | archive-date=July 21, 2010 | url-status=dead }}</ref> 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.<ref name="DailyTech1">{{citation |url=http://www.dailytech.com/Article.aspx?newsid=7623 |title=Gunning for Mobilty: Intel and AMD Bet on a Mobile Internet |publisher=Dailytech.com |date=2007-06-13 |access-date=2012-01-27 |archive-url=https://web.archive.org/web/20140202121630/http://www.dailytech.com/Article.aspx?newsid=7623 |archive-date=2014-02-02 |url-status=dead }}</ref><ref>{{cite web | url=http://ir.amd.com/phoenix.zhtml?c=74093&p=irol-analystday | title=Analyst Day 2009 Presentations | date=November 11, 2009 | publisher=AMD | access-date=2009-11-14 | archive-url=https://web.archive.org/web/20170417070752/http://ir.amd.com/phoenix.zhtml?c=74093&p=irol-analystday | archive-date=April 17, 2017 | url-status=dead }}</ref> 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,<ref>AMD 2003 Microprocessor Forum Slides: [http://pc.watch.impress.co.jp/docs/2007/0529/kaigai363_05l.gif Slide 11] and [http://pc.watch.impress.co.jp/docs/2007/0529/kaigai363_04l.gif Slide 22]</ref> 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.

In February 2013, AMD detailed plans for a successor to ''Bobcat'' codenamed ''Jaguar''.
