Kab lus no piv ob qhov tsis ntev los no System-on-Chips (SoC), Apple A5 thiab Qualcomm Snapdragon S3, tsim los rau cov neeg siv khoom siv hluav taws xob los ntawm Apple thiab Qualcomm feem. Hauv Layperson lub sij hawm, SoC yog lub computer ntawm ib qho IC (Integrated Circuit, aka nti). Technically, SoC yog IC uas koom ua ke cov khoom siv hauv lub computer (xws li microprocessor, nco, input / output) thiab lwm lub tshuab uas ua haujlwm rau hluav taws xob thiab xov tooj cua. Ob lub Apple A5 thiab Qualcomm Snapdragon S3 yog Multiprocessor System-on-Chip (MPSoC), qhov twg tus tsim siv multiprocessor architecture rau kev siv lub computer muaj zog. Thaum Apple tso A5 thaum Lub Peb Hlis 2011 nrog nws iPad2, Qualcomm Snapdragon tso tawm thaum xyoo 2010.
Feem ntau, cov khoom tseem ceeb ntawm SoC yog nws CPU (Central Processing Unit) thiab GPU (Graphics Processing Unit). Cov CPUs hauv Apple A5 thiab Qualcomm Snapdragon yog raws li ARM's (Advanced RICS - Txo Cov Kev Qhia Teeb Meem Computer - Tshuab, tsim los ntawm ARM Holdings) v7 ISA (Instruction Set Architecture, ib qho uas yog siv los ua qhov chaw pib tsim lub processor). Ob lub MPSoCs yog tsim nyob rau hauv TSMC's (Taiwan Semiconductor Manufacturing Company) 45nm technology.
Apple A5
A5 yog thawj zaug ua lag luam thaum Lub Peb Hlis 2011, thaum Apple tso nws cov ntsiav tshuaj tshiab, iPad2. Tom qab Apple lub iPhone tsis ntev los no clone, iPhone 4S tau tso tawm nrog Apple A5. Apple A5 yog tsim los ntawm Apple thiab tsim los ntawm Samsung sawv cev ntawm Apple. Raws li kev tawm tsam rau nws thawj Apple A4, A5 muaj dual cores hauv nws ob qho tib si CPU thiab GPU. Yog li, technically Apple A5 tsis yog SoC xwb, tab sis kuj yog MPSoC (Multi Processor System ntawm Chip). A5's dual core CPU yog raws li ARM Cotex-A9 processor (uas siv tib yam ARM v7 ISA uas yog siv los ntawm Apple A4), thiab nws cov tub ntxhais dual GPU yog raws li PowerVR SGX543MP2 cov duab processor. A5's CPU feem ntau yog clocked ntawm 1GHz (lub clocking siv zaus scaling; yog li ntawd, lub moos ceev yuav hloov ntawm 800MHz mus rau 1GHz, raws li lub load, lub hom phiaj txuag lub zog), thiab nws GPU yog clocked ntawm 200MHz. A5 muaj ob qho L1 (kev qhia thiab cov ntaub ntawv) thiab L2 cache nco. A5 los nrog 512MB DDR2 nco pob uas feem ntau clocked ntawm 533MHz.
Snapdragon S3
Qualcomm tau tso tawm ntau tus Snapdragon SoCs nyob rau peb lub xyoos dhau los raws li cov npe lag luam sib txawv xws li MSM7230, MSM7660 thiab lwm yam; Txawm li cas los xij, nyob rau lub Yim Hli 2011, lawv tau txiav txim siab muab tag nrho lawv nyob rau hauv plaub lub npe yooj yim, uas yog Snapdragon S1, S2, S3 thiab S4, kom cov neeg siv tuaj yeem nkag siab zoo dua lawv cov khoom thiab zam kev tsis meej pem. Yog li ntawd, cov npe loj ntawm SoCs Ameslikas muaj npe ntawm tus kheej tau muab tso ua ke rau hauv cov pab pawg saum toj no thiab cov npe ntawm cov pab pawg raws li, tus lej loj dua, cov yam ntxwv ntau dua hauv SoC (piv txwv li, Snapdragon S3 yuav muaj cov yam ntxwv siab dua li Snapdragon. S2). Cov SoCs nrov uas tau muab faib rau hauv Snapdragon S3 yog raws li hauv qab no: 8X60 [APQ8060, MSM8260, MSM8660].
Txawm hais tias Scorpion siv ARM's v7 ISA (kev qhia teeb tsa architecture, ib qho uas yog siv los ua qhov chaw pib ntawm kev tsim cov processor), lawv tsis siv ARM's CPU tsim xws li nrov ARM Cotex series rau lawv cov qauv tsim. Thawj lub Snapdragon S3 MPSoC tau tso tawm nyob rau lub quarter thib peb ntawm 2010. Thawj lub xov tooj ntawm tes siv MPSoC no yog HTC's Sensation mobile xov tooj, uas tau tso tawm thaum lub Tsib Hlis 2011. Tom qab ntawd, ntau lwm yam khoom siv tes siv tau siv Snapdragon S3 raws li lawv xaiv MPSoC thiab. qee qhov ntawm lawv yog HP Touchpad, HTC Vivid, HTC EVO 3D, ASUS Eee Pad MeMO, thiab HTC Puccini Tablet.
Lub S3 xa tawm Scorpion dual core CPU (uas siv ARM's v7 ISA) thiab Adreno 220 GPU ntawm lub nti. Cov CPUs siv feem ntau yog clocked ntawm 1.2GHz thiab 1.5GHz. Snapdragon S3 muaj ob qho tib si L1 cache (kev qhia thiab cov ntaub ntawv) thiab L2 cache hierarchies, thiab nws tso cai rau ntim txog li 2GB qis zog DDR2 nco modules.

Summary
Hauv cov ntsiab lus, Apple A5 thiab Qualcomm Snapdragon S3 muaj cov yam ntxwv sib piv. Ob leeg siv CPU architecture zoo sib xws [ISA tib yam, sib txawv hardware architecture] (nrog rau lub moos nrawm dua hauv Snapdragon S3). Apple A5 siv lub GPU zoo dua nrog cov duab ua haujlwm nrawm dua vim nws lub zog dual PowerVR SGX543MP2 GPU. Nws tau raug pov thawj tias GPU siv hauv Apple A5 ua tau zoo tshaj qhov siv hauv Snapdragon S3.
