No official Wi-Fi or flash memory card readers were ever released by Sony for the 20 GB system, although Sony had plans to do so. This was due to the removal of 'Graphics Synthesizer' GPU, which stripped the units of all PlayStation 2 based hardware. The 40 GB, 80 GB (CECHL, CECHM, and CECHK) and 160 GB models have two USB ports instead of the four USB ports on other models and do not include multiple flash card readers, SACD support, or backward compatibility with PlayStation 2 games. Due to the elimination of the 'Emotion Engine' and its replacement with a software-emulated version, the level of PlayStation 2 compatibility was slightly reduced. However, it retains the 'Graphics Synthesizer' GPU resulting in a hybrid hardware and software emulation. The European 60GB model (CECHC), the South Korean and North American CECHE 80GB model excludes the PlayStation 2 ' Emotion Engine' CPU chip with it being replaced by an emulated version via the Cell Broadband Engine. In terms of hardware, the 80 GB model CECHE released in South Korea is identical to the 60 GB model CECHC released in the PAL regions, except for the difference in hard drive size. In addition to all of the features of the 20 GB model, the 60 GB model has internal IEEE 802.11 b/g Wi-Fi, multiple flash card readers (SD/MultiMedia Card, CompactFlash Type I/Type II, Microdrive, Memory Stick/PRO/Duo) and a chrome colored trim. All models, excluding the 20 GB model, include 802.11 b/g Wi-Fi. Compatibility issues with games for both systems are detailed in a public database hosted by the manufacturer. The original and CECHExx models were also the only video game consoles ever made to feature a Super Audio CD player.Īll models support software emulation of the original PlayStation, but support for PlayStation 2 backward compatibility diminished with later compatible models and the last model to have integrated backward compatibility was the NTSC 80 GB (CECHE) Metal Gear Solid 4 Bundle. All retail packages include one or two Sixaxis controllers or a DualShock 3 controller (beginning J ), one Type-A to Mini-B USB cable (for connecting the controller and PlayStation Portable to the system), one composite video/stereo audio output cable, one Ethernet cable (20, 60 and CECHExx 80 GB only) and one power cable.

The only difference in the appearance of the first five models was the color of the trim, number of USB ports, the presence or absence of a door (which covers the flash card readers on equipped models) and some minor changes to the air vents.

Although referred to by their HDD size, the capabilities of the consoles vary by region and release date. There are several original PlayStation 3 hardware models, which are commonly referred to by the size of their included hard disk drive: 20, 40, 60, 80, or 160 GB.
