Bulldozer was AMD's microarchitecture codename for server and desktop [[AMD FX]] processors, first released on October 12, 2011. This [[Zen 4|family 15h microarchitecture]] is the successor to the [[AMD 10h|family 10h (K10)]] microarchitecture design. Bulldozer was a clean-sheet design, not a development of earlier processors.<ref>{{Citation |title=Bulldozer 50% Faster than Core i7 and Phenom II |date=January 13, 2011 |url=http://www.techpowerup.com/138328/Bulldozer-50-Faster-than-Core-i7-and-Phenom-II.html |publisher=techPowerUp |access-date=January 23, 2012}}</ref> The core was specifically aimed at 10–125&nbsp;W [[Thermal Design Power|TDP]] computing products. AMD claimed dramatic performance-per-watt efficiency improvements in [[high-performance computing]] (HPC) applications with Bulldozer cores. While hopes were high that Bulldozer would bring AMD to be performance-competitive with Intel once more, most benchmarks were disappointing. In some cases the new Bulldozer products were slower than the K10 models they were built to replace.<ref>{{Citation |title=Analyzing Bulldozer: Why AMD's chip is so disappointing |newspaper=Extremetech |date=October 24, 2011 |url=http://www.extremetech.com/computing/100583-analyzing-bulldozers-scaling-single-thread-performance |publisher=extremetech.com |access-date=November 30, 2013|last1=Hruska |first1=Joel }}</ref><ref>{{Citation |title=Lab Tested: AMD's Bulldozer Packs Plenty Of Cores, But Not Enough Power |date=October 12, 2011 |url=http://www.pcworld.com/article/241812/lab_tested_amds_bulldozer_packs_plenty_of_cores_but_not_enough_power.html |work=PC World |access-date=November 30, 2013}}</ref><ref>{{cite web |date=October 20, 2011 |title=Can AMD survive Bulldozer's disappointing debut? |url=https://arstechnica.com/gadgets/2011/10/can-amd-survive-bulldozers-disappointing-debut/ |access-date=November 30, 2013 |publisher=ars technica}}</ref>

===== Low-power Cat cores =====
{{Main|Bobcat (microarchitecture)|l1=Bobcat microarchitecture|Jaguar (microarchitecture)|l2=Jaguar microarchitecture|Puma (microarchitecture)|l3=Puma microarchitecture}}
The [[Bobcat (microarchitecture)|Bobcat microarchitecture]] was revealed during a speech from AMD executive vice-president Henri Richard in [[Computex]] 2007 and was put into production during the first quarter of 2011.<ref name="Hruska" /> Based on the difficulty competing in the x86 market with a single core optimized for the 10–100&nbsp;W range, AMD had developed a simpler core with a target range of 1–10&nbsp;watts.<ref>{{cite web |last=Stokes |first=Jon |date=August 26, 2010 |title=AMD's Bobcat mobile architecture will play it straight |url=https://arstechnica.com/business/2010/08/amds-bobcat-plays-it-straight/ |access-date=July 11, 2017 |website=Ars Technica}}</ref> 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&nbsp;W.<ref>{{Cite news |last=Kirsch |first=Nathan |date=August 6, 2007 |title=AMD and Intel Rivalry Moves to Hand-Held Market |publisher=Legit Reviews |url=https://www.legitreviews.com/amd-and-intel-rivalry-moves-to-hand-held-market_3781 |access-date=July 11, 2017}}</ref>
