简介
在PlayStation 3发布7年后,PlayStation 4终于横空出世了!和我们一起踏上PS4的拆解之旅吧~况且这台PS4还是北美第一批主机的其中一台!顺便感谢一下我们的合作伙伴Chipworks。

视频概述
-
-
-
开拆之前,先看看PS4的一些参数:
-
8核的AMD “Jaguar”架构 x86-64 CPU;
-
1.84 TFLOPS AMD Radeon GPU;
-
8GB GDDR5内存;
-
500GB硬盘,可自行替换/升级;
-
802.11 b/g/n无线网络及蓝牙2.1;
-
USB 3.0和10/100/1000M有线网络;
-
1.21G瓦的Flux电容(好吧,这个的可能性确实不大)(注:这个东西出自作品《回到未来》,它“使穿越时空成为可能”)
-
-
在这个步骤中使用的工具:Precision Tweezers Set$11.95
-
想要继续深♂ 入PS4主机,就不得不搞掉保修标签了。当然,这个教程里保修标签是用iFixit自家的镊子揭开的。
-
底下的螺丝是内六角梅花螺丝,这种螺丝对于我们来说当然是小菜一碟的。
-
在Pro Tech Screwdriver Set(专业技术螺丝刀套装)的加持下, 特殊螺丝也不过如此。
-
虽然我们乐于看到这不是被死死贴上去的,但在给可修复性打分时,我们绝对会记下这一笔的。
-
-
-
-
在索尼自己做的PlayStation 4拆解里,索尼的工程总监Yasuhiro Ootori向我们展示了下PS4那直径85毫米的涡轮风扇。
-
当然,左边的这个视频不是索尼官方的,而是我们的首席信息架构师Miroslav Djuric对PS4风扇的看法。
-
-
-
你还没逃过这次拆解,电源供应器。是时候揭露你那令人好奇的秘密了。
-
将电源供应器从其外壳中取出后,呈现出的景象正如我们所料:大电容,但其中没有任何我们正在寻找的“通量”。
-
看来这个电源供应器只会随时间前进。(叹气)
-
现在电源供应器已经拆下,你终于可以 清洁你的散热风扇了。
-
-
-
我们要拆解的目标是光驱,它由几颗螺丝固定。
-
遗憾的是,PS4 不向下兼容 PS3、PS2 或 PS1 游戏。虽然这个光驱 可能会读取你旧有的光盘,但它无法运行这些游戏。
-
奇怪的是,它也不能播放音乐 CD,不过这看起来仅仅是个软件限制,索尼计划在之后的更新中修复它。
-
但既然我们已经掌握了 云端的力量,谁还需要光驱呢?
-
鉴于此,索尼计划在 2014 年推出一项由 Gaikai 技术支持的游戏流媒体服务,让你能在 PS4 上游玩 PS3 游戏。所有的处理工作都将由索尼的服务器在“云端”完成,并仅将视频画面传输到你实际的主机上。
-
话说得虽好,但还是让我们回到真正关心的问题上:我们能玩到 古惑狼 吗?

-
SCEI CXD90025G 用于网络任务的辅助/低功耗处理器

-
人们总说,隔壁的集成电路(IC)总是更“绿”一点……
-
Genesys Logic GL3520 USB 3.0 集线器控制器
-
Samsung K4G41325FC-HC03 4 Gb (512 MB) GDDR5 内存(共 8 x 512 MB = 4 GB)
-
International Rectifier 35858 N326P IC2X
-
Macronix 25L1006E CMOS 串行闪存
-
39A207 1328 E1 3FU

-
-
你问一号门后面是什么?
-
Panasonic MN86471A HDMI 通信 LSI
-
那二号门后面呢?
-
Marvell Wireless Avastar 88W8797 7 集成式 2x2 WLAN/蓝牙/FM 单芯片 SoC
-
Skyworks 2614B 315BB
-
-
最后的想法
- 没有使用粘合剂,使得拆卸和重新组装变得容易。
- 非专有硬盘易于拆卸和更换,且更换硬盘不会使你的保修失效。
- 安全螺丝和防拆密封条会阻止用户自行拆卸和维修 PS4。
- 你需要拆卸相当多的部件才能触及风扇进行清洁,若要更换风扇则需拆卸更多部件。
- 如果在拆卸过程中不小心,锋利的中框边缘可能会划伤你的手指。

extra 256mB DDR3 chip eh? strange design. sat normally everything is upside down in the case.. and the way it sucks air through the power supply, then through the heatsink and up into the case.. guess the hot air blows out of the front? or is there something on the other side of the bottom cover to guide it towards the back? also saw that replaceable cr2032 battery... that will be dead in 4 years and I don't think anyone's gonna be replacing it.. wonder why they didn't stick in a rechargeable one like the dreamcast. or make it a user changeable one like the wii/wii u
Traditionally, blower fans blow air out of a system (hence the name). So no, it isn't drawing air in through the PSU, that wouldn't make much sense.
Also, I've seen plenty of 10+ year old systems with BIOS batteries that are still fine, so I've no idea where you've got that 4 year life from.

Figuring out the airflow of the PS4 is like doing origami. The air comes in from the top of the back and goes out the bottom of the back. There is a aluminum-mobo-aluminum sandwich about a half inch thick in between.
The air come in through the top slots, over and through the bottom of the sandwich as the mobo is upside down. The air cools the sheet, cools the memory chips by little dimples on the sheet and then is sucked through the sandwich by many small holes in the sheet metal and then through the mobo- yes, there are airholes strategically placed on the the mobo! Look by the battery for most of them that are directly over the fan intake.
Now the air comes to the fan intake via those small holes and a couple of vents over the hard drive. The cutouts over the fan intake are particularly strange, square holes, small round holes, L shaped holes. From there it is out the fan across the top sheet, then the CPU/GPU heatsink, again with memory dimples, and out through the hot parts of the power supply.

You may be right John - from the blower design I'd assumed there were vents on the bottom, but there don't appear to be, at least from the unboxing videos I've seen. Having the intake and exhaust right next to each other is traditionally a no-no for cooling, off the top of my head I can't think of any other piece of consumer electronics that does it like this.

the dreamcast DID have a cr2032, in both the console AND the VMU's
