Qual­comm Snap­dragon S4

Gadgets and Gizmos (India) - - LIVING TECH -

Last year, the smart­phone in­dus­try up­graded to dualcore pro­ces­sors from sin­gle-cores. In rapid suc­ces­sion, the year 2012 is all set to be dom­i­nated by the smart­phones and tablets run­ning on quad-core pro­ces­sors. All chip­mak­ers are bet­ting high on their new chips sup­port­ing quad-core CPUS, among them Qual­comm. From the Sys­tem 1 that was meant for mass mar­ket smart­phones to S2 and S3 for high per­for­mance smart­phones/tablets and mul­ti­task­ing and ad­vance gam­ing, Qual­comm has now in­tro­duced the all-new Snap­dragon S4 chipset. The Snap­dragon S4 is a pow­er­ful chip meant to do much more for next gen­er­a­tion de­vices. The S4 means the in­tro­duc­tion of Qual­comm’s sec­ond gen­er­a­tion CPU named the ‘Krait ’. This new mi­cro-ar­chi­tec­ture in­creases the per­for­mance by 60 per cent over the ex­ist­ing Scor­pion pro­ces­sor. The S4 pro­ces­sor fam­ily also in­cludes the Adreno 225 GPU that de­liv­ers 50 per cent greater graph­ics pro­cess­ing power over the ex­ist­ing Adreno 220 and can go up to Adreno 320. In sim­ple terms, the Snap­dragon S4 fam­ily will of­fer chips in fu­ture with sin­gle, dual and quad core CPUS with ‘Krait ’ ar­chi­tec­ture that can be clocked at a speed of up to 2.5GHZ. Like the S3 chipsets, even the S4 will be ca­pa­ble of cap­tur­ing full HD video (1080p res­o­lu­tion). In­ter­est­ingly, the new chip sup­ports up to three cam­eras with up to 20 megapixel along with a stereo­scopic kit that en­ables 3D video play­back, 2D to 3D con­ver­sion and 3D con­tent cap­ture. Along with the su­pe­rior speeds, the de­vices pow­ered by S4 are likely to of­fer su­perb gam­ing ex­pe­ri­ence and graphic in­ter­face. The S4 chip also in­te­grates the 4G/LTE mode. This new pro­ces­sor has been man­u­fac­tured us­ing 28 nanome­ter process tech­nol­ogy in­stead of the 45 nano­mater used in the ear­lier chips. The net re­sult is that the same work is now be­ing han­dled by a much smaller chip that will in­herit ad­van­tages in fre­quency scal­ing, power con­sump­tion and size re­duc­tion. Dr Paul Ja­cobs, Chair­man and CEO, Qual­comm, said at Las Ve­gas, “There are al­ready 300 de­vices us­ing Snap­dragon and an­other 350 in de­vel­op­ment.

Snap­dragon pro­ces­sors are all about do­ing more and charg­ing less”. Also, the Snap­dragon pro­ces­sors are not just re­stricted to smart­phones and tablets any­more. The chipsets are all set to power Wi-fi dis­plays and Smart TVS as well.
