去年 iPhone 6s 的 A9 處理器,分別找上台積電和三星電子代工,結果兩個版本的處理
器效能不一,引發網友不滿,爆發「晶片門」風波,不少用戶要求退換貨,改用台積版。
如今類似的測試結果又在 iPhone 7 的 modem 上演!
i7 系列的 modem,分別由高通(Qualcomm)和英特爾(Intel)供應。測試顯示,高通版
modem 明顯優於英特爾,下載速度更快、訊號也更強,差距達 30% 之多。
AppleInsider、Fortune 20 日報導,高通是 modem 晶片領導者,數十年來稱霸市場;英
特爾近來才加強研發,參與戰局。去年的 iPhone 6s 全數採用高通 modem,今年
iPhone 7 改變策略,把 modem 訂單從高通全包,改成由高通和英特爾分食。
Cellular Insights 找來搭載高通和英特爾 modem 的 iPhone 7 Plus 做測試,比較兩款
晶片在不同訊號強度下的表現。他們模擬真實世界情況,用戶接近基地台時訊號最強、遠
離時訊號轉弱。與此同時,由於各國和各電信商採用不同 LTE 頻段,他們也以 3 種
LTE 頻段進行試驗。
結果發現,幾乎在各種情況下,高通版表現都優於英特爾版。平均而言,高通 modem 表
現比英特爾好上 30%;在訊號較弱的狀況下,高通版更大勝 75%。這表示買到高通版
iPhone 7,下載速度更快、訊號更好。Cellular Insights 表示,在所有測試中,高通
modem 都明顯優於英特爾,不清楚蘋果為何要找兩家 modem 供應商。
Forbes 批評,此一測試結果相當重要,消費者可能用同樣的錢,卻買到品質較差的
iPhone 7。蘋果向來自豪於品質優越、表現一致,試驗結果卻並非如此。
心得:
繼去年 iPhone 6s 的 CPU 晶片門事件,今年的 iPhone 7 一樣也出了晶片門事件,只是
主角變成 modem 晶片而已。目前業界大概也僅蘋果有這個本事能由兩家不同的廠商提供
同一功能晶片,但是在效能不可能完全相同的情況下,蘋果還沒從上次的晶片門學到教訓
嗎?除非蘋果原本就是打算要讓使用者公測不同來源晶片的效能,還是不要在同規格的機
型混用不同廠商提供的晶片吧!
