Pixel 6a

Google 每年秋季登場的新一代 Pixel 新機總是讓人充滿期待,但其實次年夏天的 Pixel-a 系列手機也不遑多讓。雖然它不像旗艦 Pixel 機種一樣,有著最先進的硬體,但通常都是在中階價位中數一數二的好選擇,特別是在拍照方面,向來都保持著與旗艦 Pixel 機種相同的硬體配置。

不過,今年的 Pixel 6a 上 Google 做出了重大的改變,讓它不是繼承 Pixel 6 的相機,而是選用了與 Pixel 6 / 6 Pro 相同的 Tensor 處理器,讓它在實質上成為與 6 / 6 Pro 相同的「旗艦」。當然,為了維持中階的定價,Pixel 6a 還是要有所犧牲,那究竟差在哪裡呢?讓我們一起來看看吧。

和所有的 a 系列 Pixel 機種一樣,6a 在設計上同樣承繼了 Pixel 6 Pro / Pixel 6 的設計語言。在背後的上側是一條非常醒目的黑色「護目鏡」橫幅,內藏有 Pixel 6a 的兩顆鏡頭和 LED 補光燈,而橫幅也同時將背板切成了上下兩個部份。在小編拿到的這台「灰綠色」Pixel 6a 上,黑橫幅以上的部份是較淺的青綠色,而以下的部份則是較深的灰綠色;而 Pixel 6a 還有「粉炭白」(淺灰+白)和「石墨黑」(深灰+黑)兩個配色。

雖然說設計上雷同,但相對於 6 / 6 Pro(上圖右),6a(上圖左)的鏡頭部份只有突出來非常小的一點點,這讓它放到桌上時不會像 6 / 6 Pro 翹起那麼多。除開了背面的不同,Pixel 6a 與 Pixel 6 的設計非常近似,都是黑色的霧面中框,搭配正面的全平面打孔屏,打孔的位置也都在上方中央。不過雖然設計近似,在零件的選擇上還是有些許不同的 —— Pixel 6 採用的是 Gorilla Glass Victus 的正面玻璃,背面也是玻璃材質,而 Pixel 6a 則是 Gorilla Glass 3 的正面玻璃,背面也是「熱壓成型的 3D 複合材質機背」(塑膠),但其實握在手中的觸感基本上是一樣的,都很滑溜。

Pixel 6a 整體來說比 Pixel 6 要小一圈,成為這一代 Pixel 三兄弟中最小的一支。它採用的 6.1 吋螢幕大小適中,算不上是大螢幕手機,但也沒有像 iPhone SE 的 4.7 吋那麼小。機身全重 173g,比 Pixel 6 輕了約 30g,當兩支手機一起拿在手中時差距相當明顯。

Pixel 6a 為 IP67 的防水防塵等級,稍差兩個兄弟的 IP68 一線,但對於一般日常使用應該是沒有太大的差別。比較可惜的是,到 Pixel 5a 為止每一代 Pixel a 系列都有耳機插孔,這次卻被移除了,或許 Google 認為 Pixel Buds a 系列已經將無線耳機的價位降至一般人也能接受的程度了吧。

螢幕顯示、指紋辨識

Pixel 6a 的 6.1 吋 OLED 螢幕解析度為 2,400 x 1,080(20:9),與 Pixel 6 相同。這意味著 Pixel 6a 有著略高的畫素密度,但其實實際看起來並沒有太明顯的分別。然而,Pixel 6a 的面板只支援最高 60Hz 的更新率,遜於 Pixel 6 的 90Hz,更別說 6 Pro 的 120Hz 了。60Hz 面板究竟算不算是缺點,小編覺得是很看個人的,有些人對於高更新率很敏感,但小編自己是屬於看不太出來分別的那一類人。最明顯的可能是在快速卷動的時候,60Hz 的畫面會看起來有點卡卡的,但這也要兩支手機同時放在一塊對比才看得出來,小編自己是覺得在一般日常使用上沒有太大的不同的。

和 Pixel 6 / 6 Pro 一樣,Pixel 6a 也是採用了屏下指紋的設計。 Pixel 6 / 6 Pro 的屏下指紋被很多用戶嫌速度慢,但小編自己用 6 Pro 這麼多個月,也是早就習慣了。Pixel 6a 的指紋辨識感覺在辨識速度、辨識準確性上都和 6 / 6 Pro 沒有太大的區別,同樣要等個小半秒才會解鎖,但準確度是沒問題的。

相機

這麼多年以來,每次講到 Pixel a 系列手機時,其最大的賣點總是在於「平價機種,搭載著 Google 最先進的相機」,但這次 Pixel 6a 卻打破了這個慣例,並沒有採用 Pixel 6 / 6 Pro 的 50MP 主鏡,而是保持了 12.2MP 的主鏡。Pixel 的老用戶聽到「12.2MP」大概就會抖一下,而各位並沒有猜錯,這就是 Google「祖傳」的那顆 12MP IMX363 感光器,從 Pixel 3 一直用到現在。

雖然說已經用了快四年,但實話說 Google 當年靠著 AI 運算,已然將這個感光器推上超一流的水準,即使過了這麼多年,在各家廠商的技術皆已推陳出新之下,它拍出來的照片依然有一流的水準。何況 Google 對這顆感光器的調校可以說是瞭若指掌,在色彩和低光處理上的表現,甚至可以說比新的 50MP 感光器都要更穩定一些。即便不是最新一代的感光器,Pixel 6a 的拍照表現在中階機依然是數一數二的呢。

而且,Pixel 6a 的副鏡選擇了 12MP 的超廣角鏡,在實用性上小編認為還是副鏡中比較高的。畢竟「微距鏡」、「景深鏡」都有點湊數的意味,而「望遠鏡」則是可以用裁切來替代,真正無法被取代的,果然還是超廣角吧。

雖然說感光器是舊的,但 Pixel 6a 一樣是能享受 Pixel 6 / 6 Pro 的一些軟體工具,像是可以智慧移除多餘背景人物的「智慧橡皮擦」、可以在低光環境中保持人臉清晰不模糊的「人臉清晰功能」,以及「自然色調」功能等。可以預見的是,未來 Google 推出更多這種靠 AI 運算而來的功能時,Pixel 6a 也都能繼續享受呢。

Tensor 晶片、電力

說到 AI 運算功能,那就要談到 Pixel 6a 的核心 —— Tensor 晶片了。相對於過去 Pixel a 系列都是繼承旗艦機種的相機,而此次卻是採用了與 Pixel 6 / 6 Pro 相同的 Tensor 處理器,就能看出 Google 在著眼點上與過去的不同。Google 希望 Pixel 6a 在 AI 功能上能與 Pixel 6 / 6 Pro 同步,而且更重要的,在未來 Google 推出更多 AI 功能時,也不會讓 Pixel 6 家族中有所落差,而是所有的機種都能一併獲得。

當然,這麼一來的附加好處,就是 Pixel 6a 在使用體驗上完全是旗艦機的水準,無論是在 app 間切換、玩遊戲、拍攝 4K/60p 影片等,都是無比滑順。不過,Tensor 晶片的發熱量比較高不是什麼祕密,Pixel 6a 自然也難以例外,當你進行比較「高強度」的活動(像是拍照)時,就能感受到中框開始升溫,更別說是原神,中框發燙不說,背後也是相當熱。Pixel 6a 搭了 6GB 的 RAM,也是少於 Pixel 6 的 8GB 或 Pixel 6 Pro 的 12 GB 的。

Pixel a 系列向來有著不錯的電池壽命,而 6a 也不例外。雖然說換上了更強力的 Tensor 晶片,但大概是因為 60Hz 面板這邊又省下了不少電,總體來說 Pixel 6a 的 4,410mAh 電池在一般使用上比 Pixel 6 / 6 Pro 兩兄弟都還要再長一些,用得省一點的話,大概撐到接近兩天都可以。比較可惜的,是 Pixel 6a 沒有加入無線充電,但 Pixel a 系列向來也都是沒有無線充電的,倒也不能說是缺點就是了。

結語

Sam Rutherford / Engadget

Pixel 6a 代表著 Pixel a 系列手機的一個新方向,雖然說它依然是家族三兄弟最便宜的一員,但其旗艦級的處理器,保證了未來至少數年內只要是 Pixel 6 或 Pixel 6 Pro 能獲得的新 AI 機能,Pixel 6a 也將能享用。當然,為了要達成 NT$13,990 這樣的中階價位,Google 依然必需要在他處進行取捨,像主鏡感光器是用了 N 年的 12.2MP、螢幕為較小的 6.1 吋更新率僅有 60Hz、且背蓋為塑膠材質等等。但這些顯然都是 Google 考量過 Pixel 客群的需求後,進行取捨的結果,畢竟快速、乾淨的介面,以及強大的 AI 功能,才是 Pixel 手機最大的賣點吧。就這點來說,Pixel 6a 無疑是在中階機當中畫出了屬於自己的地盤了呢。

Pixel 6a 目前在台灣已經開始預購,且 7 月 31 日前購入 Pixel 6a 的話,就送 Pixel Buds A 系列真無線耳機,也算是解決了沒有耳機孔的問題。正式開賣為 7 月 28 日,屆時預購手機也將陸續出貨。
