Much of the Game Gear's internal hardware is derived from the [[Master System]], as the handheld was designed to be compatible with that system's library of games. It shares the same CPU, the [[Zilog Z80]],<ref name="Japanese Manual page 18">{{cite book |date=1990 |publisher=[[Sega Enterprises Ltd.]] |page=18 |language=ja |script-title=ja:ゲームギア 取扱説明書 |trans-title=Game Gear Instruction Manual}}</ref> an [[8-bit processor]] clocked at 3.5{{nbsp}}MHz, and the same sound chip, a [[Texas Instruments SN76489]], a [[programmable sound generator]]. The chip generated [[stereo sound]],  audible using [[headphones]] as the device only included a single [[monaural]] speaker. The system also contains 8{{spaces}}[[kilobyte|KB]] of [[random-access memory|RAM]] and 16{{spaces}}KB of [[video RAM]].

The Game Gear measures {{convert|210|mm|sp=us}} wide, {{convert|113|mm|abbr=on}} high, {{convert|38|mm|abbr=on}} deep,<ref name="Japanese Manual page 18" /> and was designed to be played horizontally.<ref name="IGNGG">{{cite web|url=http://uk.retro.ign.com/articles/918/918381p1.html|title=Remember Game Gear?|author=Buchanan|first=Levi|date=October 9, 2008|website=[[IGN]]|archive-url=https://web.archive.org/web/20180623173244/http://www.ign.com/articles/2008/10/09/remember-game-gear|archive-date=June 23, 2018|url-status=live|access-date=March 29, 2009}}</ref> At the center of the device is a color [[liquid-crystal display]] that measures {{convert|3.2|in}} diagonally and is able to display up to 32 simultaneous colors from a total palette of 4,096,<ref name="allgame">{{cite web|url=http://www.allgame.com/platform.php?id=25|title=Sega Game Gear - Overview|author=Beuscher|first=David|publisher=[[AllGame]]|archive-url=https://web.archive.org/web/20141114094408/http://www.allgame.com/platform.php?id=25|archive-date=November 14, 2014|access-date=July 8, 2013}}</ref> with a [[frame rate]] of about 60{{nbsp}}[[Hertz|Hz]]{{efn| The exact frame rate was 59.922751013551{{nbsp}}Hz<ref>{{Cite web|url=http://tasvideos.org/PlatformFramerates.html|title=TASVideos / Platform Framerates|website=tasvideos.org|access-date=March 4, 2020}}</ref>}} with 160{{nbsp}}×{{nbsp}}144 [[Pixel aspect ratio|non-square pixel]]s.<ref name="RetroGamer" /><ref name="encyclopedia">{{cite book|title=The Encyclopedia of Game.Machines: Consoles, Handhelds, and Home Computers 1972-2005|author=Forster|first=Winnie|publisher=Variant Press|year=2005|isbn=3-0001-5359-4|page=139}}</ref> The screen is backlit for low light using a small [[cold cathode fluorescent lamp]] tube. 

The Game Gear is powered by six [[AA battery|AA batteries]] which provide an approximate [[Battery (electricity)#Battery lifetime|battery life]] of 3 to 5 hours. This was a source of significant criticism from reviewers.<ref name="RG2" /> In response, Sega released two types of external rechargeable battery packs, intended to lengthen play time and reduce consumer cost.<ref name="allgame" /><ref>{{cite magazine|date=April 1994|title=GamePro Labs|pages=104–106|magazine=[[GamePro]]|publisher=[[International Data Group|IDG]]|issue=57|url=https://archive.org/details/GamePro_Issue_057_April_1994/page/n89/mode/2up}}</ref>

Available accessories included a [[Tuner (radio)#Television|TV Tuner]] with a [[whip antenna]] for the cartridge slot, to become a [[handheld television]]. Released at {{GBP|74.99}} (equivalent to {{US$|{{to USD|74.99|GBR|year=1991|r=-1}}}}), the add-on was expensive but unique for collectors and contributed to the system's popularity.<ref name="RetroGamer" /> The Super Wide Gear magnifies the screen. The Car Gear adapter plugs into [[cigarette lighter receptacle|cigarette lighter]]s to power the system while traveling, and the Gear to Gear Cable (VS Cable in Japan) establishes a data connection between two Game Gear systems using the same [[Multiplayer video game|multiplayer]] game.<ref name="allgame" />  Master Gear enables the Game Gear to play Master System games.<ref name="Game Gear Compatibility">{{cite web|title=GameSpot Presents: The History of Video Game Compatibility|url=http://www.gamespot.com/gamespot/features/video/compat/p3_02.html|url-status=dead|archive-url=https://web.archive.org/web/20041031213027/http://www.gamespot.com/gamespot/features/video/compat/p3_02.html|archive-date=October 31, 2004|access-date=August 6, 2008|website=[[GameSpot]]}}</ref>
