Apple A6 vs Samsung Exynos 5 Octa
Cov kab lus no tau sib piv thiab sib piv qhov sib txawv ntawm Apple A6 thiab Exynos 5 Octa, ob qho tib si niaj hnub System-on-Chips (SoC) tsim thiab tsim los ntawm Apple thiab Samsung lub hom phiaj ntawm tes. SoC yog ib lub computer ntawm ib qho IC (Integrated Circuit, aka nti). Technically, SoC yog ib qho IC uas sib txuas 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 tawm A6 thaum lub Cuaj Hlis 2012, Samsung tshaj tawm Exynos 5 Octa thaum Lub Ib Hlis 2013 (cia siab tias yuav tso tawm lub Plaub Hlis 2013).
Feem ntau, cov khoom tseem ceeb ntawm SoC yog nws CPU (Central Processing Unit) thiab GPU (Graphics Processing Unit). Cov CPUs hauv Apple A6 thiab Samsung Exynos 5 Octa 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).
Apple A6
Apple, lub cim lag luam uas paub txog kev ua txhaum kev cai, tsoo nws tus kheej kev lig kev cai ntawm kev tso tawm cov txheej txheem loj nrog nws cov iPads tshiab kawg thaum nws txiav txim siab tso Apple A6 processor nrog iPhone (iPhone 5) thaum lub Cuaj Hlis 2012. As opposed rau cov neeg nyiam ntseeg tias Apple yuav coj nws cov quad-core CPU hauv A6, A6 tau nruab nrog dual-core processor zoo ib yam li nws cov A5 processor. Txawm li cas los xij, A6 muaj qhov hloov kho ntawm ISA uas tau siv hauv A5 thiab hauv tsev processor architecture, hu ua Apple Swift (uas yog qhov zoo dua nrog qhov tseeb vector ua, hais tsawg kawg). Txawm hais tias A6 tau nruab nrog dual-core CPU zoo ib yam li A5, (1) Apple thov tias nws yog ob zaug sai li A5 thiab (2) qee qhov kev ntsuas ntsuas tau ua los ntawm cov neeg sab nrauv xyuas tau qhia tias A6 ua tau zoo dua A5, vim rau nws cov txheej txheem qhia kho dua tshiab thiab kho vajtse architecture. A6 processor ntseeg tau tias yuav tsum tau clocked ntawm 1.3GHz, sai npaum li A5. GPU siv (uas yog lub luag haujlwm rau cov duab ua haujlwm) hauv A6 yog triple-core PowerVR SGX543MP3, tsis zoo li dual-core GPU hauv A5. Yog li ntawd, cov duab ua tau zoo ntawm A6 yog qhov zoo dua li ntawm Apple A5 processor. A6 yuav tsum tau xa nrog 32KB L1 ntiag tug cache nco ib tus tub ntxhais (rau cov ntaub ntawv thiab kev qhia cais) thiab 1MB sib koom L2 cache, zoo li cache configurations ntawm nws cov thawj coj. A6 MPSoCs kuj tseem thauj khoom sai dua 1GB DDR2 (tsawg zog) SDRAMs.
Samsung Exynos 5 Octa
Raws li koj xav tau los ntawm nws lub npe, Exynos 5 Octa yuav tsum nqa 8 (yog yim!) cores hauv nws tuag. Txawm li cas los xij, nws yuav tsum ua haujlwm zoo li Quad-Core processor nyob ntawm hom nws yuav tsum ua haujlwm. Ntawm hom kev ua haujlwm siab, ARM Cortex A15 pawg ntawm cov txheej txheem (plaub cores) yuav ua haujlwm, thiab ntawm hom kev ua haujlwm siab (ua kom muaj zog txaus) ARM Cortex A7 pawg ntawm cov txheej txheem (dua ntxiv plaub cores) yuav ua haujlwm. Qhov ntawd yog A7 yog rau lub zog qis, kev ua haujlwm qis thiab A15 yog rau lub zog siab, kev ua haujlwm siab. Tag nrho 8 cores, 4 x A15 thiab 4 x A7 yuav nyob rau tib qhov tuag accustom rau lub system-on-chip. Nws tau thov tias Samsung, tsis zoo li nws cov kev lig kev cai, yuav tsis siv ARM's GPU es yuav siv Kev xav lub PowerVR SGX544MP3 (peb cores) rau nws cov duab ua haujlwm.
Cov lus qhia siv los ntawm ob pawg processors yuav yog ARMv7, thiab lawv yuav siv 28nm HKMG txheej txheem thev naus laus zis rau kev tsim cov chips. Thaum lub Cortex A15 pawg yuav tsum tau clocked ntawm 1.8GHz max, Cortex A7 pawg yuav tsum moos ntawm 1.2 GHz max. Tsis tas li ntawd, pawg qub raug xa nrog 2MB L2 cache, thiab pawg tom kawg yuav tsuas muaj ib nrab ntawm MB L2 cache.
Exynos 5 Octa xav tias yuav tso tawm nrog Samsung Galaxy S4 tom qab lub hlis no (Lub Plaub Hlis, 2013). Galaxy S4 yuav yog tus ua tiav rau lub npe nrov Galaxy SIII.

Apple A6 vs Samsung Exynos 5 Octa
Samsung Exynos 5 Octa, sib nrug los ntawm kev ua thawj yim-ntxhais MPSoC hauv kev ua lag luam, nqa ntau yam zoo nkauj xws li kev txuag hluav taws xob thiab kev siv cov txheej txheem zoo dua. Rau nws cov kev siv thiab kev ua tau zoo, peb yuav tsum tau tos ntev me ntsis. Ntxiv rau, Samsung Exynos 5 Octa muab ntau yam piv rau Apple's A6.
