At the 2013 California Raw Championships, he set the American Powerlifting Record for the state of California for his weight class and age group in bench press, dead lift, squat, and all three combined lifts.<ref>{{Cite web |url=https://www.openpowerlifting.org/u/davidpatterson3 |title=Open Powerlifting Record for David Patterson}}</ref>

On February 12, 2015, IEEE installed a plaque at UC Berkeley to commemorate the contribution of RISC-I<ref>{{cite web|url=https://r6.ieee.org/sv-techhistory/?p=297|title=IEEE SCV Silicon Valley Technology History Committee|website=[[IEEE]]}}</ref> in Soda Hall at UC Berkeley. The plaque reads:
* ''IEEE Milestone in Electrical and Computer Engineering''
* First RISC (Reduced Instruction Set Computing) Microprocessor
*''UC Berkeley students designed and built the first VLSI reduced instruction-set computer in 1981. The simplified instructions of RISC-I reduced the hardware for instruction decode and control, which enabled a flat 32-bit address space, a large set of registers, and pipelined execution. A good match to C programs and the Unix operating system, RISC-I influenced instruction sets widely used today, including those for game consoles, smartphones and tablets.

On March 21, 2018,  he was awarded the 2017 ACM A.M. [[Turing Award]] together with [[John L. Hennessy]] for developing RISC.<ref name=nytimes/> The award attributed them for pioneering "a systematic, quantitative approach to the design and evaluation of computer architectures with enduring impact on the microprocessor industry".<ref name=turing>{{Cite web|url=https://www.acm.org/media-center/2018/march/turing-award-2017|title=John Hennessy and David Patterson will receive the 2017 ACM A.M.

In 2022 he was awarded the [[Charles Stark Draper Prize]] by the [[National Academy of Engineering]] alongside [[John L. Hennessy]], [[Steve Furber]] and [[Sophie Wilson]] for contributions to the invention, development, and implementation of [[reduced instruction set computer]] (RISC) chips.<ref name=risc>{{cite web|url=https://www.nae.edu/55291/DraperWinners|website=nae.edu|title=Recipients of the Charles Stark Draper Prize for Engineering}}</ref><ref name=draper>{{cite web|url=https://www.nae.edu/20681/DraperPrize|website=nae.edu|title=Charles Stark Draper Prize for Engineering}}</ref>

===Charitable work===
From 2003 to 2012 he rode in the annual Waves to Wine MS charity event as part of [[Bike MS]]; a 2-day cycling adventure. He was the top fundraiser in 2006, 2007, 2008, 2009, 2010, 2011, and 2012.<ref>{{cite web|url=http://anti-ms-crew.berkeley.edu/theteam.shtml|title=Berkeley's Anti-MS Crew|website=anti-ms-crew.berkeley.edu}}</ref>
