Samsung Exynos 5 Dual vs Exynos 5 Octa
Cov kab lus no sib piv thiab sib piv qhov sib txawv ntawm Exynos 5 Dual thiab Exynos 5 Octa, ob qho tib si niaj hnub System-on-Chips (SoC) tsim thiab tsim los ntawm Samsung lub hom phiaj ntawm tes. Ib SoC yog lub khoos phis tawj 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 Samsung tso tawm Exynos 5 Dual thaum Lub Kaum Hli 2012, nws tshaj tawm Exynos 5 Octa thaum Lub Ib Hlis 2013.
Feem ntau, cov khoom tseem ceeb ntawm SoC yog nws CPU (Central Processing Unit) thiab GPU (Graphics Processing Unit). Cov CPUs hauv ob qho tib si Exynos 5 Dual thiab Exynos 5 Octa yog ua 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). Lub Exynos 5 Dual thiab Exynos 5 Octa yog tsim los siv cov txheej txheem semiconductor hu ua High-K Hlau Gate (HKMG) 32nm thiab 28nm feem.
Samsung Exynos 5 Dual
Samsung Exynos 5 Dual yog thawj zaug MPSoC siv dual core ARM Cortex A15 processor architecture. Thaum nws tau tshaj tawm, lub hom phiaj ntaus ntawv rau txhua lub zog Exynos 5 Dual yog lub ntsiav tshuaj PC, hu ua Samsung Chromebook Series 3. Tom qab ntawd, MPSoC tau hloov kho los ntawm lwm yam khoom siv xws li Google Nexus 10, Samsung Galaxy Mega 6.3. Ntawm qhov kev thov, Samsung tau thov tias lub processor yuav raug clocked ntawm 2GHz targeting high-end ntsiav tshuaj PCs. Txawm hais tias, ntawm kev tso tawm zaus hloov kho yog 1.7GHz.
Atypical rau MPSoC, cov lus qhia siv los ntawm processor yog ARMv7. Lub processor kuj tseem featured ARM's Mali-T604, Quad-Core kev ua haujlwm siab ntawm cov duab ua haujlwm uas yog clocked ntawm ntau zaus siab dua 500MHz. Kev ntsuas ntsuas tau ua tiav ntawm ntau qhov ua pov thawj tias ob qho tib si CPU thiab GPU ntawm Exynos 5 Dual zoo dua li Exynos 4 Quad. Zoo ib yam li Exynos 4 Dual thiab Quad, Exynos 5 Dual siv 32nm HKMG txheej txheem thev naus laus zis.
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 uas nws yuav ua haujlwm rau. 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. 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 1.2GHz 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.
