Apple A4 vs Samsung Exynos 3110 |Samsung Exynos 3110 vs Apple A4 Ceev thiab Kev Ua Haujlwm
Cov kab lus no piv ob qhov tsis ntev los no System-on-Chips (SoC), Apple A4 thiab Samsung Exynos 3110, ua lag luam los ntawm Apple thiab Samsung feem tsom rau cov khoom siv tes tuav. 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. Thaum Apple tso nws A4 processor nyob rau hauv lub Peb Hlis 2010 nrog nws inaugural ntsiav tshuaj PC, Kua iPad, Samsung tso Exynos 3110 nyob rau hauv Lub rau hli ntuj 2010 nrog nws Samsung Galaxy S ntse xov tooj.
Feem ntau, cov khoom tseem ceeb ntawm SoC yog nws CPU (Central Processing Unit) thiab GPU (Graphics Processing Unit). CPUs nyob rau hauv ob qho tib si A4 thiab Exynos 3110 yog raws li ARM's (Advanced RICS - Txo Kev Qhia Teeb 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) thiab Ob lub SoCs yog tsim los siv lub tshuab semiconductor hu ua 45nm.
Ob Samsung Exynos 3110 thiab Apple A4 yog raws li SoC tsim co-tsim los ntawm Samsung thiab Intrinsity (lub tuam txhab tsim nti tom qab tau los ntawm Apple) hauv qab lub npe hummingbird. Thaum Samsung coj Hummingbird rau nws tus qauv Exynos 3110, Apple tau hloov kho qhov hloov kho ntawm Hummingbird rau nws A4 processor. Thaum lub sijhawm tsim, Hummingbird tau suav tias yog SoC rau cov tiam tom ntej kev ua haujlwm siab thiab cov khoom siv hluav taws xob tsawg.
Apple A4
A4 yog thawj zaug ua lag luam thaum Lub Peb Hlis 2010, thiab Apple siv nws rau lawv Apple iPad, thawj ntsiav tshuaj PC ua lag luam los ntawm Apple. Tom qab kev xa tawm hauv iPad, Apple A4 tom qab tau xa mus rau hauv iPhone4 thiab iPod kov 4G. A4's CPU yog tsim los ntawm Apple raws li ARM Cortex-A8 processor (uas siv ARM v7 ISA), thiab nws GPU yog raws li PowerVR's SGX535 graphics processor. CPU hauv A4 moos ntawm qhov ceev ntawm 1GHz, thiab GPU lub moos ceev yog qhov tsis paub (tsis tau qhia los ntawm Apple). A4 muaj ob qho tib si L1 cache (kev qhia thiab cov ntaub ntawv) thiab L2 cache hierarchies, thiab nws tso cai rau ntim DDR2 nco blocks (txawm hais tias nws tsis muaj lub cim xeeb module ntim thaum chiv thawj). Qhov ntau thiab tsawg ntawm lub cim xeeb ntim sib txawv ntawm cov khoom siv sib txawv xws li 2x128MB hauv iPad, 2x256MB hauv iPhone4.
Samsung Exynos 3110
Lub Rau Hli 2010, Samsung hauv nws Galaxy S thawj zaug xa tawm Exynos 3110 (aka Samsung S5PC110). Cov neeg tsim qauv siv ARM's Cotex A8 architecture rau nws CPU thiab PowerVR's SGX540 architecture rau GPU. Ib qho tseem ceeb CPU hauv Exynos 3110 siv ob qho tib si L1 (kev qhia thiab cov ntaub ntawv) thiab L2 cache hierarchies. Lub SoC yog stacked feem ntau nrog 512MB DDR2 (Double Data Rate Synchronous Random Access Memory, version 2 - DDR2 SDRAM), tawm ntawm 128MB yog siv los ntawm GPU ua nws cov cache. Nrog rau qhov tshwj xeeb (thiab weird) cache configuration, tus tsim qauv thov tsis tau xav txog kev ua haujlwm siab ntawm cov nti no.
Kev sib piv ntawm Apple A4 thiab Exynos 3110 yog tabulated hauv qab no.

Summary
Hauv cov ntsiab lus, Apple A4 thiab Samsung Exynos 3110 muaj cov yam ntxwv sib piv. Muab hais tias lawv tau tso tawm rau lub sijhawm zoo sib xws, lawv tau siv cov qauv zoo sib xws. Ob leeg siv tib lub CPU architecture (nrog rau tib lub moos zaus) thaum Exynos 3110 siv GPU zoo dua nrog kev txhawb nqa cov duab nrawm dua (tsuas yog vim nws tshwj xeeb GPU cache thiab vim nws nrawm dua GPU clocking zaus). Txawm hais tias, ob qho tib si muaj qhov zoo sib xws CPU cache configurations, Exynos 3110 muaj ntau lub cim xeeb hauv nws thawj zaug tso tawm (384MB zoo hauv Galaxy S vs. 256MB hauv iPad). Txawm li cas los xij, tom qab xa tawm ntawm Apple A4, xws li ib qho hauv iPhone4 muaj 512MB ntim nrog nws. Thaum qhov kev tso tawm thawj zaug tau txiav txim siab, Samsung Exynos 3110 me ntsis ua tau zoo dua Thov A4 (uas feem ntau xav tau hauv hom thev naus laus zis no nrog peb lub hlis ncua sijhawm rau kev ua lag luam).
