NVIDIA Tegra 3 vs Samsung Exynos 4210 | Samsung Exynos 4210 vs NVIDIA Tegra 3 Ceev, Performance
Kab lus no piv ob qhov tsis ntev los no System-on-Chips (SoC), NVIDIA Tegra3 thiab Samsung Exynos 4210, xa mus rau cov neeg siv khoom siv hluav taws xob los ntawm Apple thiab Samsung 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 leeg NVIDIA Tegra3 thiab Samsung Exynos 4210 yog Multiprocessor System-on-Chip (MPSoC), qhov twg tus tsim siv multiprocessor architecture rau kev siv lub computer muaj zog. Thaum Exynos 4210 tuaj rau lub Plaub Hlis 2011; Samsung tso nws Galaxy S2 nrog Exynos 4210; NVIDIA tso Tegra3 thaum Lub Kaum Ib Hlis 2011, thiab nws tseem tsis tau siv rau hauv cov khoom siv hluav taws xob.
Feem ntau, cov khoom tseem ceeb ntawm SoC yog nws CPU (Central Processing Unit) thiab GPU (Graphics Processing Unit). Cov CPUs hauv NVIDIA Tegra3 thiab Exynos 4210 yog raws li ARM's (Advanced RICS - Txo Cov Kev Qhia Teeb Lub Computer - Tshuab, tsim los ntawm ARM Holdings) v7 ISA (Instruction Set Architecture, ib qho uas yog siv los ua qhov chaw pib ntawm kev tsim lub processor).
NVIDIA Tegra3 (Series)
NVIDIA, Ameslikas yog GPU (Graphics Processing Unit) lub tuam txhab tsim khoom [tau lees tias tau tsim GPUs hauv lub nineties lig] tau tsis ntev los no tau tsiv mus rau hauv kev lag luam txawb, qhov twg NVIDIA's System ntawm Chips (SoC) tau xa mus rau hauv xov tooj, ntsiav tshuaj thiab lwm yam khoom siv tes tuav. Tegra yog SoC series tsim los ntawm NVIDIA lub hom phiaj xa mus rau hauv kev ua lag luam txawb. Thawj MPSoC hauv Tegra3 series tau tso tawm thaum lub Kaum Ib Hlis 2011 thiab tseem yuav raug xa mus rau hauv cov khoom lag luam muag.
NVIDIA thov tias Tegra3 yog thawj lub xov tooj ntawm tes super processor, muab quad core ARM Cotex-A9 architecture thawj zaug. Txawm hais tias Tegra3 muaj plaub (thiab yog li ntawd quad) ARM Cotex-A9 cores raws li nws lub ntsiab CPU, nws muaj ib qho auxiliary ARM Cotex-A9 core (lub npe hu ua tus khub tub ntxhais) uas zoo ib yam hauv architecture rau lwm tus, tab sis yog etched ntawm lub zog qis. ntaub thiab yog clocked ntawm ib tug tsawg zaus. Thaum lub cores tseem ceeb tuaj yeem ua haujlwm ntawm 1.3GHz (thaum tag nrho plaub lub cores ua haujlwm) mus rau 1.4GHz (thaum tsuas yog ib qho ntawm plaub cores ua haujlwm), cov tub ntxhais tseem ceeb yog clocked ntawm 500MHz. Lub hom phiaj ntawm lub auxiliary core yog khiav cov txheej txheem tom qab thaum lub cuab yeej nyob rau hauv standby hom; yog li ntawd, txuag lub zog. GPU siv hauv Tegra3 yog NVIDIA's GeForce, uas muaj 12 cores ntim rau hauv nws. Tegra 3 muaj ob qho tib si L1 cache thiab L2 cache, uas zoo ib yam li Tergra 2, thiab nws tso cai rau ntim txog li 2GB DDR2 RAM.
Samsung Exynos 4210
Lub Plaub Hlis 2011, Samsung hauv nws lub Galaxy S2 thawj zaug xa tawm Exynos 4210. Exynos 4210 tau tsim thiab tsim los ntawm Samsung nyob rau hauv lub codename Orion. Nws yog ib tug successor rau Samsung Exynos 3110. Nws CPU yog dual core ARM Cotex A9 series clocked ntawm 1.2GHz thiab nws GPU yog ARM tus nto moo Mali-400MP (4 core) tsim clocked ntawm 275MHz. Exynos 4210 yog thawj SoC (lossis MPSoC) los siv ARM's Mali-400MP. Lwm qhov kev nyiam rau Exynos 4210 yog nws haiv neeg kev txhawb nqa rau peb cov lus (triple display outs: 1xWXGA, 2xWSVGA), uas yog ib qho yooj yim heev rau cov khoom siv uas tau tsom los ntawm Exynos 4210. Lub nti tau ntim nrog L1 (kev qhia thiab cov ntaub ntawv) thiab L2 cache. hierarchies thiab muaj 1GB DDR3 SDRAM inbuilt.
Kev sib piv ntawm NVIDIA Tegra3 thiab Exynos 4210 yog tabulated hauv qab no.

Summary
Hauv cov ntsiab lus, NVIDIA, hauv lub npe Tegra 3 series, tau tawm los nrog MPSoC nrog lub peev xwm siab. Nws pom tseeb tias ua tau zoo dua ntawm kev suav lub zog thiab cov duab kos duab. Lub tswv yim ntawm tus khub tseem ceeb yog qhov zoo nkauj heev, vim tias nws tuaj yeem siv siab rau cov khoom siv mobile xws li cov khoom siv nyob rau hauv hom standby ntau dua li tsis tau thiab lawv yuav tsum tau ua haujlwm tom qab. Qee tus tuaj yeem sib cav tias cov ntaub siv hluav taws xob kim kim siv hauv cov tub ntxhais sib koom ua ke tuaj yeem ua rau cov neeg siv khoom hnyav. Yuav ua li cas kev lag luam hauv xov tooj ntawm tes yuav siv lub peev xwm thiab kev ua lag luam ntawm Tegra3 tseem tsis tau pom.
