官方宣稱PS4主機的運算能力大約是PS3主機的二十倍,遊戲畫面進一步提升解像度到“高達1080P”、每秒顯示張數“高達每秒60張”。對比PS3,PS4加入不少特色,例如跨遊戲語音聊天功能、轉型成真實好友構成的網絡以及透過Ustream和Twitch網路串流實況轉播遊玩畫面。據稱有更多的PS4機能將會陸續推出。[19]
在主机开发过程中,为了避免过于追求性能而使制作游戏软件更加困难的情况的发生,索尼放弃了 PlayStation 3 原有的设计,重新选择了与个人电脑相同的 X86 架构,使得游戏开发更加容易[20];但是缺點是與PS3、PS2或是PSone®遊戲不相容。
PlayStation 4使用了由索尼與超微半導體合作開發的處理器,整合了中央處理器(CPU)、圖形處理器(GPU)以及包括内存控制器和視訊編解碼器在內的其他元件。[22]其共計八核心的中央處理器是由兩個x86-64架構的四核心AMD Jaguar模組組成。[22][23]圖形處理器由18個運算單元組成,理論上具有最高每秒1.84兆次的浮點運算能力(TFLOPS)。[24]主機的GDDR5記憶體的最高運作時脈為2.75 GHz(每秒5500 MT),其最大記憶體頻寬為每秒176 GB。[24][25][26]PlayStation 4配有共8 GB的GDDR5記憶體,[24][27]是PlayStation 3系統的16倍之多,被認為將可讓主機的市場壽命更長。[28][29]主機內另配有一個專責處理下載、上傳和社群遊玩相關功能的次要處理器。[30][31]這些功能可在遊戲進行中或主機待機時在背景執行。[32]主機內也包含了一個音訊模組,能夠支援遊戲內語音交談,以及在遊戲中處理「十分大量」的音訊串流。[33]
PlayStation 4搭載的唯讀式光碟機能讀取藍光光碟(PlayStation 4成为PlayStation系列首款未升级光盘介质的游戏机),其讀取速度最快可達到PS3的三倍,光碟置入方式與PS3一樣為無托盤的吸入式(slot-in)。[29][34]主機內建硬體解壓縮模組,能夠加快光碟的讀取速度,並在遊戲不需存取光碟內容時將尚未讀取的資料暫時保存,這項功能是索尼「PlayGo」策略的一部份。[33]雖然主機具有4K解析度照片和影片的播放能力,但無法渲染解析度超過1080p的遊戲。[35][36]主機內建500 GB容量的硬碟作為額外的儲存空間,[37]使用者也可自行升級更換硬碟(支持7mm与9mm厚的2.5英寸规格硬盘)。[38][39]
PlayStation 4支援WiFi、乙太網路連結和藍牙傳輸,並有兩個USB 3.0連接埠。[24][29]此外也有一個可連接動作感應裝置PlayStation Camera的接孔。[24]主機包裝內付有一個可與DualShock 4連結的單聲道耳機麥克風組。[40]視訊和音訊的輸出界面支援HDMI和光纖S/PDIF音訊。[24]主機無法輸出類比視訊和音訊。[41]
PlayStation 4內建支援110-240伏特的通用交流電電源供應器,[45]其最大電源值為250瓦特。根據Eurogamer網站的測試,主機在操作選單時消耗約80瓦特的電力,在遊戲進行中則會提升至110-120瓦特,在選單模式和遊戲中最高可達到140瓦特的功耗。[46]而自然資源保護協會(NRDC)的測試結果也顯示了相近的數據,在遊戲進行時最高功耗為137瓦特(包含連結PlayStation Camera);在待機模式下(連結網路)測量的功耗為8.8瓦特,而關機狀態下則為0.5瓦特。[47]
控制器
主条目:DualShock 4和PlayStation Move
DualShock 4
PlayStation 4的主要控制器是DualShock 4,透過藍牙2.1+EDR與主機連結[48],舊款控制器DualShock 3則無法在PlayStation 4上使用[49]。DualShock 4加入了數項全新的功能,包括正面配有可按壓的雙點電容式感應觸控板[40]。此外控制器亦支援動態感測,內建三軸陀螺儀和三軸加速器,其震動功能亦有改進[40][48]。DualShock 4也是第一款正式支援Windows個人電腦的PlayStation原廠控制器[50]。控制器內建不可拆除的充電式鋰電池,容量為800 mAh[51][40]。控制器重量約為210克,尺寸為162x52x98毫米,使用橡膠與塑膠材質增加握持感[48][51]。
PlayStation Camera是一個可另選購的動態感測配件。其包含兩個1280x800像素的鏡頭,光圈值為f/2.0,焦距為30cm,具備85度的視野範圍[40]。雙鏡頭的設計能依據各種應用來改變操作模式[53]。兩個鏡頭同時使用下可在攝影機視野範圍內對物體進行深度偵測[54],與Xbox的Kinect系統原理相同[55]。此外,其中之一的鏡頭可進行影像拍攝,而另一個鏡頭則可用來偵測動作[56]。
PlayStation Camera亦內建一組四聲道麥克風[40],可幫助降低背景噪音,並可接收語音控制命令[53]。攝影機的尺寸為186x27x27厘米,重量為183克[40]。攝影機與主機上的AUX連接埠相連,可錄製RAW和未壓縮的YUV格式影像[40][49]。
軟體與服務
参见:PlayStation 4系统软件
PlayStation 4使用者界面
PlayStation 4上運行的作業系統名為「Orbis OS」,改寫自FreeBSD 9.0作業系統[57][58]。索尼電腦娛樂的網站上證實Orbis OS使用了FreeBSD的核心架構[59]。
PlayStation 4在推出後透過軟體更新提供播放數位音樂光碟(CD)、MP3和DLNA伺服器媒體的功能。[67]
使用者界面
PlayStation 4放棄了PlayStation 3中的跨界導航選單(XMB),改用了全新設計的使用者界面,稱為「PlayStation動態選單」(PlayStation Dynamic Menu)[44][68][69]。玩者的使用者檔案中會顯示近期的活動記錄、獲得的獎盃,以及其他進一步的資訊[70]。系統的主畫面也會顯示可自定的好友動態等內容。此外,各項如Netflix、Hulu等第三方服務也能透過新界面啟動[71]。系統亦支援多工處理,例如在進行遊戲的同時開啟網路瀏覽器等[24]。
PlayStation 4在發售時所提供的第三方線上服務依據國家而有所不同。PlayStation 4在2013年11月15日於美國上市,同時提供的數位娛樂軟體共有11款,包括Amazon Instant Video、Crackle、Crunchyroll、EPIX、Hulu Plus、NBA Game Time、Netflix、NHL GameCenter LIVE、Redbox、VUDU和YuppTV[72][73][74]。在日本則預計將推出「JOYSOUND DIVE 2」(名稱暫定)線上卡拉OK服務[75]。
PlayStation 4最初在2013年11月15日於北美州市場率先發售,接著於歐洲、南美洲、大洋洲、非洲、中東和亞洲(日本和中國大陸除外)地區陸續上市。其中與過往PlayStation系列主機不同的是,在亞洲市場中,韓國、香港、台灣比日本更早推出[122]。製造商索尼所屬的國家日本則是在2014年2月22日上市[123]。

Plato, the Greek philosopher, is universally known by a single name. A mononymous person is an individual who is known and addressed by a single name, or mononym. [a] [b] In some cases, that name has been selected by the individual, who may have originally been given a polynym ("multiple name"). In other cases, it has been determined by the custom of the country [c] or by some interested segment. In the case of historical figures, it may be the only one of the individual's names that has survived and is still known today.
