期的跡象顯示,SoC與CPU存在明顯的沖突。微軟的Surface平板電腦突顯出OEM廠商在在決定處理器架構(gòu)時(shí)擁有更多的選擇。這款平板電腦將做成兩種版本──其一使用基于ARM的SoC處理器(Nvidia Tegra 3),另一版本使用基于英特爾x86 CPU(Ivy Bridge)。表1對(duì)這兩種版本的相關(guān)規(guī)格作了比較,圖1顯示兩種晶片及其架構(gòu)圖。從中可明顯看出,基于SoC的設(shè)計(jì)更能有效適應(yīng)超行動(dòng)裝置用戶對(duì)于外形尺寸的要求──重量輕和電池壽命長(zhǎng)比塬始性能高顯得更有價(jià)值。
圖1:由核心/繪圖主導(dǎo)的典型CPU設(shè)計(jì)(英特爾Ivy Bridge)與高度整合的SoC(Nvidia Tegra)的比較。這種整合的SoC設(shè)計(jì)在平板電腦和ultrabook架構(gòu)中具有明顯的優(yōu)勢(shì)(來(lái)源:英特爾/Nvidia網(wǎng)站)。
基于CPU的設(shè)計(jì)需要依賴更多晶片實(shí)現(xiàn)必要的硬體整合,不僅會(huì)消耗更多功率,而且導(dǎo)致最終產(chǎn)品更重30%也更厚40%。有趣的是,基于Nvidia SoC的設(shè)計(jì)採(cǎi)用落后的40nm微影制程,而基于英特爾CPU的設(shè)計(jì)使用的是領(lǐng)先兩代的22nm微影製程。當(dāng)SoC公司轉(zhuǎn)向使用高k值/金屬閘電晶體的28nm技術(shù)時(shí),上述比較將更值得玩味。Surface平板電腦將成為重要的比較標(biāo)準(zhǔn),因?yàn)樗诠δ芊矫婧统杀痉矫娑寄芴峁┠壳?領(lǐng)先CPU與突破性/邊緣性SoC之間的直接比較。
