新聞標題: 台積電 4 奈米果然贏三星?聯發科「天璣9000 」能耗、效能皆擊敗高通 S8
Ge
在推出首款最頂規的行動處理晶片「天璣 9000」後,聯發科稍早也釋出工程機的效能測
試成績。而據知名自媒體《極客灣》及聯發科官方數據,「天璣 9000」的效能在 CPU 部
份,亦超越了高通的 Snapdragon 8 Gen 1 約 17%,以及蘋果前一代的 A14 處理器,成
為目前 Android 陣營 CPU 效能最高的晶片。
此外,儘管 CPU 效能領先高通,但「天璣 9000」在能耗上亦展現優勢,雖然仍比蘋果的
A15、A14 高,但多核時 9.8W、單核時 3.5W 的成績,皆領先高通的 11.1W,這意味著
「天璣 9000」能以較少的能耗,繳出比 Snapdragon 8 Gen 1 更好的效能成績。

《極客灣》認為,由於架構相近,「天璣 9000」與高通 Snapdragon 8 Gen 1 的效能差
距,可能更多地反映了台積電 4 奈米製程相比三星,確實在能耗方面有更多優勢。
不過,「天璣 9000」在 GPU 圖像方面,則仍然落後 Snapdragon 8 Gen 1,前者在
GFXBench 繳出 100 分的成績,而 Snapdragon 8 Gen 1 則是 115 分,亦不如蘋果前代
A14 的 108 分。

不過如同 CPU,GPU 的能耗仍是「天璣 9000」的優勢,平均為 8.2W,領先高通的
11.2W 不少,這也讓「天璣 9000」的能耗比得以超越高通的 Snapdragon 8 Gen 1。
至於在實際遊戲體驗方面,若以高畫質開啟《原神》,「天璣 9000」的平均能耗則為
6.8W,同樣領先高通,幀率能達到 60fps,亦是聯發科晶片的歷來最佳,同時是聯發科
首次能繳出此一表現;若將遊戲時間拉長,「天璣 9000」則為能耗 5.7W,搭配 48fps,
整體水準則和高通前一代的 Snapdragon 888 差不多,但能耗同樣優於前者,以及高通新
的 Snapdragon 8 Gen 1。

若改以中畫質開啟《原神》,「天璣 9000」則會有與 Snapdragon 8 Gen 1 相當的表現
。《極客灣》並總結,「天璣 9000」在 CPU 部份確定成為 Android 手機龍頭,而 GPU
圖像雖然不如大躍進的高通,但仍然有一定水準,預估在遊戲體驗上,也能藉由能耗優勢
,繳出和 Snapdragon 8 Gen 1 相近的成績,不過因「天璣 9000」的能耗仍算不上低,
最終表現仍得視手機廠商的調校而定。
《極客灣》也認為,對在意效能的用戶來說,2022 年將可以開始考慮入手採用聯發科高
階晶片手機,且若後者的終端產品定價更低,可以立刻決定改買搭載「天璣9000」的產品
。
