A ceramic white PSP-1000. The shoulder buttons are on top, the directional pad on the left with the analog 'nub' directly below it, the PlayStation face buttons on the right and a row of secondary buttons below the screen.

The PlayStation Portable uses the common "slab" or "candybar" form factor, measures approximately 17 x 7.3 x 2.2 cm (6.7 x 2.9 x 0.9 in), and weighs 280 grams (9.88 ounces). The front of the console is dominated by the system's 11 cm (4.3 in) LCD screen, which is capable of 480 x 272 pixel video playback with 16.77 million colors. Also on the front are the four PlayStation face buttons (Triangle, Circle, X, Square), the directional pad, the analog 'nub', and several other buttons. In addition, the system includes two shoulder buttons and a USB 2.0 mini-B port on the top of the console and a WLAN switch and power cable input on the bottom. The back of the PSP features a read-only UMD drive for movies and games, and a reader compatible with Sony's Memory Stick Duo flash cards is located on the left of the system. Other features include an IrDA compatible infrared port (discontinued in PSP-2000 and later series), built in stereo speakers and headphone port, and IEEE 802.11b Wi-Fi for access to the Internet, ad-hoc multiplayer gaming, and data transfer.[7]

The PSP uses two 333 MHz MIPS32 R4000-based CPUs [101], a GPU with 2 MB onboard VRAM running at 166 MHz, and includes 32 MB main RAM and 4 MB embedded DRAM in total.[7][102] The hardware was originally forced to run more slowly than it was capable of and most games ran at 222 MHz.[103] However, with firmware update 3.50 on May 31, 2007, Sony removed this limit and allowed new games to run at a full 333 MHz.[104]

The PSP includes an 1800 mAh battery that will provide about 4–6 hours of gameplay, 4–5 hours of video playback, or 8–11 hours of audio playback.[29][105] Official accessories for the console include the AC adapter, car adapter, headset, headphones with remote control, extended-life 2200 mAh battery, battery charger, carrying case, accessories pouch and cleaning cloth, and system pouch and wrist strap.[106]

The system's processor is a 200 MHz SH-4 with an on-die 128-bit vector graphics engine, 360 MIPS and 1.4 GFLOPS (single precision), using the vector graphics engine. The graphics hardware is a PowerVR2 CLX2 chipset, capable of 7.0 million polygons/second peak performance and trilinear filtering. Graphics hardware effects include gouraud shading, z-buffering, anti-aliasing, per-pixel translucency sorting and bump mapping. The system supports approximately 16.78 million colors (24-bit) color output and displays interlaced or progressive scan video at 640x480 video resolution.

For sound, the system features a Yamaha AICA Sound Processor with a 22.5 MHz 32-Bit ARM7 RISC CPU operating at 45 MHz,[17], 64 channel PCM/ADPCM sampler (4:1 compression), XG MIDI support and 128 step DSP.

The Dreamcast has 16 MB 64 Bit 100 MHz of main RAM, 8 MB 4x16-bit 100 MHz video RAM and 2 MB 16-bit 66 MHz sound RAM. [18] The hardware supports VQ Texture Compression (5:1 texture compression)[17]

The system reads media using a 12x maximum speed (Constant Angular Velocity) Yamaha GD-ROM Drive. The Dreamcast can also read data from a Visual Memory Unit ("VMU") removable storage device and 4x memory cards that hold four times as much data. Input devices such as game controllers are connected to four USB-like "Maple Bus" ports.
A black 56k Dreamcast modem

In most regions, the Dreamcast included a removable modem. The original Asia/Japan model had a 33.6 kbit/s; consoles sold in Japan after September 9, 1999 had a 56 kbit/s modem. All American models had a 56 kbit/s modem, while all PAL models had a 33.6 kbit/s modem. Brazilian models manufactured under license by Tec Toy did not include a modem, which was available separately. The regular modem could be replaced with a broadband adapter that was sold separately.
