'''Sandy Bridge''' on varjunimi Inteli protsessorite mikroarhitektuurile, mis on järglaseks [[Nehalem]] mikroarhitektuurile.

*Protsessorituumad ja graafikaprotsessor asuvad samal kiibil (Nehalem protsessoritel asus erinevatel kiipidel aga samal plaadil)
*Iga tuuma kohta on 32&nbsp;kB andmete ja 32&nbsp;kB koodi L1 [[vahemälu]] (3&nbsp; takti) ning 256&nbsp;kB L2 vahemälu (8&nbsp;clocks)
 
==Ivy Bridge==
Ivy Bridge on Inteli varjunimi Sandy Bridge protsessoritele, mis on valmistatud 22 nm tootmismeetodil. Inteli 22 nm tootmismeetodi põhiliseks uuenduseks peale väiksemate kiipide on kolme väravaga ehk 3D transistorid. Inteli sõnul on selle tehnoloogia abil võimalik kiipide voolutarvet tunduvalt vähendada.<ref name="5Gx1n" />
Ivy Bridge protsessorid on tagasiühilduvad Sandy Bridge tooteperekonnaga. Siiski vajavad vana kiibistikuga emaplaadid baasvahetussüsteemi uuendust. Intel plaanib välja anda ka uue emaplaadi kiibistiku ([[Panther Point]]) koos Ivy Bridge protsessoriga. Panther Pointi peamiseks uueks funktsionaalsuseks on kiibistikku sisseehitatud USB 3.0 tugi ja [[PCI Express]] 3.0 siini tugi.<ref name="mAT5J" />

==Viga Cougar Point kiibistikus==
[[Image:P67_SATA_ports.jpg|220px|right|thumb|Kaks SATA III porti (valged) ja kolm SATA II porti (sinised) Gigabyte P67 kiibistikuga emaplaadil.]]
31. jaanuaril 2011 teatas Intel, et eemaldab müügilt ning kutsub tagasi kõik seni müüdud P67 ja H67 (mudel SLH84/SLH82) kiibistikul põhinevad emaplaadid. Sandy Bridge kiibistikel Z68 ja Q67 seda probleemi ei esinenud.<ref>{{cite news|titlename=Intel's"VUxsR" Sandy Bridge chipset flaw: The fallout|url=http://news.cnet.com/8301-13924_3-20030070-64.html | work=cnet.com | date=2011-01-31|accessdate=26. november 2011}}</ref>
Tagasikutsumise põhjuseks oli probleem kiibistikus, mis võib lõppeda SATA-II värati ülesütlemisega. Väratiga ühendatud kõvaketastele ja neile salvestatud andmetele ohtu ei ole.<ref>{{cite news|titlename=Tom's"p58mT" Hardware,Intel Identifies Cougar Point Chipset Error, Halts Shipments |url=http://www.tomshardware.com/news/cougar-point-sandy-bridge-sata-error,12108.html|accessdate=26. november 2011}}</ref>
Inteli sõnul esineb see probleem keskmiselt 5% kasutajatel 3 aasta jooksul. Vea tõenäosus kasvab, kui kasutaja salvestab või loeb andmeid kõvakettalt intensiivsemalt.
 
Intel peatas ajutiselt 67 seeria kiibistiku müügi oma partneritele. Kaks nädalat hiljem Intel siiski taastas vigase kiibistiku müügi arvutitootjatele tingimusel, et seda kasutatakse ainult sellistel emaplaatidel, kus see viga ei avaldu.<ref>{{cite news| titlename=Intel will continue shipping flawed Sandy Bridge chipsets| url=http://www.theinquirer.net/inquirer/news/2024817/intel-continue-shipping-flawed-sandy-bridge-chipsets|accessdate=26. november"di4Gg" 2011}}</ref>
14. veebruaril alustas Intel parandatud kiibistiku müüki (mudel P67 SLJ4C ja H67 SLJ49). Inteli hinnangul läks see probleem ettevõttele maksma 1 miljard dollarit.<ref>http: name="Kj4Pt" //www.theregister.co.uk/2011/01/31/intel_cougar_point_update/</ref>
Emaplaatide tootjad (nagu [[ASUS]] ja [[Gigabyte Technology]]) ja arvutite tootjad (nagu [[Dell]] ja [[Hewlett-Packard]]) lõpetasid vigase kiibistikuga toodete müügi ning hakkasid pakkuma kas vigase toote asendamist või ostetud toote eest raha tagasi.<ref>{{cite news| titlename=Intel"olhy5" chip bug affects HP, Dell, Samsung and Lenovo | url=http://www.bbc.co.uk/news/technology-12354263 | work=BBC News | date=2011-02-03|accessdate=26. november 2011}}</ref><ref>{{cite news|titlename=HP"hcoV2" to offer refund for PCs with flawed Intel chip | url=http://www.reuters.com/article/2011/02/02/uk-intel-hp-idUKTRE7118OL20110202 | work=Reuters | date=2011-02-02|accessdate=26. november 2011}}</ref>
 
==Kriitika==
Üldiselt on tehnikaajakirjanikud Sandy Bridge arhitektuuriga protsessorid positiivselt vastu võtnud. Kritiseeritakse vaid Inteli otsust lubada ülekellata väheseid Sandy Bridge protsessoreid. K-versiooni mudelid on ainukesed, mida on võimalik ülekellata, aga nendegi puhul on vähem võimalusi kui Nehalem arhitektuuri puhul.<ref name="1wZoq" />{{cite<ref newsname="KCubo" />

==Järeltulijad==
Sandy Bridge ja [[Ivy Bridge]] järeltulijaks on mikroarhitektuur ''[[Haswell]]''. Eeldatavalt tulevad Haswell arhitektuuril põhinevad protsessorid turule aastal 2013.<ref>{{cite news |titlename="rwMtl" Haswell chip completes Ultrabook 'revolution' |work=The Circuits Blog |publisher= CNET.com |date=14. september 2011 |url=http://news.cnet.com/8301-13924_3-20106098-64/haswell-chip-completes-ultrabook-revolution/ |accessdate=24. november 2011 }}</ref> Tootmiskulude vähendamiseks soovib Intel Haswell protsessoritel [[pingestabilisaator]]id otse protsessori plaadile panna.
