Apple A5 vs TI OMAP4430 Cov Txheej Txheem | TI OMAP 4430 vs Apple A5 Ceev, Performance
Apple A5 thiab Texas Instruments OMAP4430 yog System-on-Chips (SoC) xa mus rau hauv cov khoom siv hluav taws xob los ntawm Apple thiab Texas Instruments (TI) 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 TI OMAP4430 yog Multiprocessor System-on-Chip (MPSoC), qhov uas tus tsim siv multiprocessor architecture rau kev siv lub computer muaj zog. Apple tau tso tawm A5 thaum Lub Peb Hlis 2011 nrog nws lub iPad2, thiab TI's OMAP (cov ntawv luv rau Qhib Multimedia Application Platform) 4430 tuaj rau lub khw ib puag ncig tib lub sijhawm.
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 TI OMAP4430 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, uas yog siv los ua qhov chaw pib tsim lub processor), thiab tsim los siv cov tshuab semiconductor hu ua TSMC's (Taiwan Semiconductor Manufacturing Company) 45nm.
Apple A5
A5 tau muag thawj zaug hauv 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.
TI OMAP 4430
OMAP 4430 tau tso tawm hauv thawj peb lub hlis twg ntawm 2011 thiab raws li PDAdb.net nws tau xa mus ua ntej hauv BlackBerry's Playbook. Ntau lwm yam khoom siv xws li xov tooj, PDAs thiab ntsiav tshuaj, tom qab siv nws. PandaBoard, lub zej zog nto moo txhawb nqa kev txhim kho pawg thawj coj saib, muaj OMAP 4430 ua nws cov txheej txheem tseem ceeb. CPU siv hauv OMAP 4430 yog ARM's dual core Cotex A9 architecture thiab GPU siv yog PowerVR's SGX540. Hauv OMAP 4430, CPU yog clocked ntawm 1GHz, thiab GPU yog clocked ntawm 304MHz (uas yog kuj siab dua piv rau clocking ntawm tib GPU nyob rau hauv lwm yam SoCs qhov twg SGX540 tau deployed). Lub nti tau ntim nrog ob qho L1 thiab L2 cache hierarchies hauv nws lub CPU dual core thiab tau ntim nrog 1GB DDR2 tsawg zog RAM.
Kev sib piv ntawm Apple A5 thiab TI OMAP4430 yog tabulated hauv qab no.

Summary
Hauv cov ntsiab lus, Apple A5 thiab TI OMAP4430 muaj cov yam ntxwv sib piv. Muab hais tias lawv tau tso tawm tib lub sijhawm, lawv tau siv cov thev naus laus zis zoo sib xws ntawm lub sijhawm ntawd. Ob leeg siv tib CPU architecture (nrog zoo sib xws clocking zaus). Qhov sib txawv tseem ceeb ntawm ob tuaj yeem pom hauv lawv qhov kev xa tawm ntawm GPUs; thaum Apple A5 tau siv dual core GPU tshiab los ntawm PowerVR, TI OMAP4430 tau siv GPU qub nrog lub moos zoo dua qub (Hwj chim SGX543MP2 @ 200MHz vs. PowerVR SGX540 @ 304MHz). GPU teeb tsa siv los ntawm Apple A5 yuav tsum ua kom zoo dua qhov siv los ntawm TI OMAP4430. Txawm hais tias, ob leeg muaj qhov zoo sib xws CPU cache configurations, OMAP4430 muaj ib tug loj dua (1GB vs. 512MB) nco thiab, yog li ntawd, yuav outperform rau nco tshaib plab daim ntaub ntawv.
