Qualcomm Snapdragon S2 vs Snapdragon S3 | Qualcomm Snapdragon S2 (MSM7230, MSM7630, MSM8255, MSM8655) vs Snapdragon S3 (APQ8060, MSM8260, MSM8660)
Snapdragon S2 thiab S3 yog ob txheej ntawm System ntawm Chips (SoC) tsim los ntawm Qualcomm hauv peb lub xyoos dhau los. SoCs feem ntau yog tsim los tsom rau kev lag luam hauv xov tooj ntawm tes thiab Snapdragon S2 thiab S3 tsis muaj kev zam. Feem ntau, SoC yog lub khoos phis tawj 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.
Txawm hais tias Qualcomm tau tshaj tawm ntau tus Snapdragon SoCs hauv peb lub xyoos dhau los raws li cov npe lag luam sib txawv xws li MSM7230, MSM7630 thiab lwm yam, thaum Lub Yim Hli 2011, lawv tau txiav txim siab muab tag nrho lawv nyob rau hauv plaub lub npe yooj yim, uas yog Snapdragon S1, S2, S3 thiab S4, kom cov neeg siv tuaj yeem nkag siab zoo dua lawv cov khoom thiab zam kev tsis meej pem. Yog li ntawd, cov npe loj ntawm SoCs Ameslikas muaj npe ntawm tus kheej tau muab tso ua ke rau hauv cov pab pawg saum toj no thiab cov npe ntawm cov pab pawg raws li, tus lej loj dua, cov yam ntxwv ntau dua hauv SoC (piv txwv li, Snapdragon S3 yuav muaj cov yam ntxwv siab dua li Snapdragon. S2). Lub hom phiaj ntawm tsab xov xwm no yog sib piv Snapdragon S2 thiab S3; Cov SoCs nrov uas tau muab faib raws li S2 thiab S3 yog raws li hauv qab no:
Qualcomm Snapdragon S2: 7X30 [MSM7230, MSM7630], 8X55 [MSM8255, MSM8655
Qualcomm Snapdragon S3: 8X60 [APQ8060, MSM8260, MSM8660
Ob leeg, Snapdragon S2 thiab S3, yog tsav los ntawm Qualcomm tus kheej Scorpion CPU (Central Processing Unit, aka processor) thiab raws li Qualcomm Adreno GPU (Graphics Processing Unit). Txawm hais tias Scorpion siv ARM's v7 ISA (kev qhia teeb tsa architecture, ib qho uas yog siv los ua qhov chaw pib ntawm kev tsim cov processor), lawv tsis siv ARM's CPU tsim xws li nrov ARM Cotex series rau lawv cov qauv tsim. Ob lub Snapdragon SoCs tau tsim nyob rau hauv cov txheej txheem semiconductor hu ua 45nm ntawm TSMC (Taiwan Semiconductor Manufacturing Company).
Snapdragon S2
Snapdragon S2 SoCs tau pom thawj zaug hauv lub quarter thib ob ntawm 2010. Thawj lub xov tooj ntawm tes siv Snapdragon S2 SoC yog HTC Vision thaum Lub Kaum Hli 2010. Txij thaum ntawd los, ntau lub xov tooj ntawm tes tau siv SoC los ntawm qhov no. pab pawg thiab rau npe ob peb: LG Optimus7, HTC Desire, HP Veer, HTC Ignite, HTC Prime, Sony Ericsson Xperia Pro, thiab Motorola Triumph.
Snapdragon S2 SoCs muaj Qualcomm Scorpion ib leeg tub ntxhais CPUs (uas siv ARM's v7 ISA), uas feem ntau yog moos ntawm 800MHz-1.4GHz. GPU ntawm kev xaiv rau cov SoCs no yog Qualcomm's Adreno 205. Snapdragon S2 muaj ob qho tib si L1 cache (kev qhia thiab cov ntaub ntawv) thiab L2 cache hierarchies, thiab nws tso cai rau ntim txog 1GB qis zog DDR2 nco modules.
Snapdragon S3
Snapdragon S3 SoCs (los yog MPSoC - Ntau Cov Txheej Txheem Txheej Txheem ntawm Chip) tau tso tawm nyob rau lub quarter thib peb ntawm 2010. Thawj lub xov tooj ntawm tes siv MPSoC no yog HTC's Sensation xov tooj, uas tau tso tawm thaum lub Tsib Hlis 2011. Tom qab ntawd, ntau lwm yam khoom siv tes siv tau siv Snapdragon S3 raws li lawv xaiv MPSoC thiab qee qhov ntawm lawv yog HP Touchpad, HTC Vivid, HTC EVO 3D, ASUS Eee Pad MeMO, thiab HTC JetStream Tablet.
Lub S3 tau xa tawm Scorpion dual core CPU (uas siv ARM's v7 ISA) thiab Adreno 220 GPU ntawm lub nti. Cov CPUs siv feem ntau yog clocked ntawm 1.2GHz thiab 1.5GHz. Snapdragon S3 muaj ob qho tib si L1 cache (kev qhia thiab cov ntaub ntawv) thiab L2 cache hierarchies, thiab nws tso cai rau ntim mus txog 2GB qis zog DDR2 nco modules.
Kev sib piv ntawm Snapdragon S2 thiab Snapdragon S3 yog tabulated hauv qab no:
| Snapdragon S2 | Snapdragon S3 | |
| Hnub tso tawm | Q2 2010 | Q3 2010 |
| Type | SoC | MPSoC |
| Thawj Device | HTC Vision | HTC Sensation |
| Lwm yam khoom siv | LG Optimus7, HTC Desire, HP Veer, HTC Ignite, HTC Prime, Sony Ericsson Xperia Pro, Motorola Triumph | HP Touchpad, HTC Vivid, HTC EVO 3D, ASUS Eee Pad MeMO, thiab HTC Puccini Tablet |
| ISA | ARM v7 | ARM v7 |
| Qualcomm Scorpion (ib leeg tub) | Qualcomm Scorpion (dual core) | |
| CPU's Clock Speed | 800 MHz - 1.4 GHz | 1.2 GHz – 1.4GHz |
| YGPU | Qualcomm Adreno 205 | Qualcomm Adreno 220 |
| CPU/GPU Technology | TSMC's 45nm | TSMC's 45nm |
| Memory | Txog 1GB DDR2 | Txog 2GB DDR2 |
Summary
Nws tau lees paub los ntawm Qualcomm tias lawv cov Snapdragon S3 MPSoCs zoo dua thiab muaj cov yam ntxwv siab dua li Snapdragon S2 SoCs. Nws tsim nyog sau cia tias HTC zoo li yog lub chaw tsim khoom siv xov tooj ntawm tes uas vam khom feem ntau ntawm Qualcomm SoCs, vim tias lawv yog thawj tus siv Snapdragon S2 thiab S3 hauv lawv cov khoom siv.
