Guest Eagan469 Report post Posted July 29, 2003 PSP Specs Revealed Processing speed, polygon rate and lots more. July 29, 2003 - At a press briefing held in Japan today, Sony Computer Entertainment at last revealed detailed specs for its PSP (PlayStation Portable) portable system. Although first unveiled at E3, Sony left showgoers in the dark about what form the system would actually take. Today's announcement covers most bases, from planned CPU speed and memory space all the way to networking ability. As its CPU, PSP will make use of twin MIPS R4000 32 bit processors running at max 333 Megahertz. One of these units is referred to as the Media Engine, and is to be used for sound, movies and I/O management. In addition, the system will include a so-called VFPU floating point vector unit with calculation capability of up to 2.6 Gigaflops. This latter unit is meant for assisting the CPU in 3D calculations. Memory for the system is divided into two areas. In all, the system is expected to feature 8 Megabytes main memory with bandwidth of 2.6 Gigabytes per second along with two megabytes of sub-memory, also at 2.6 Gigabytes per second, which will be used by the Media Engine. Outside of the CPU and main memory, the system will of course include a graphics processing unit (GPU). The GPU is made up of a Rendering Engine and a Surface Engine and has access to 2 Megabytes of VRAM with a bandwidth of 5.3 Gigabytes per second. The hardware will include support for traditional polygons as well as curved surface primitives along with such things as clipping, morphing and more, freeing up software from having to deal with these. Sony claims a theoretical polygon performance of 33 million polygons per second. The system's UMD (Universal Media Disc) optical disk format has also been clarified a bit. A UMD is a 60 millimeter dual layered disk that can store up to 1.8 Gigabytes of data. Transfer rate for the reader unit is 11 Megabits per second, which is twice the transfer rate of a standard DVD system. Sony is also promising the highest level of copy protection for these discs using DiscID and AES encoding technology. Multimedia support is big for the system. Sony announced MPEG4 support at E3, and now they've gotten a bit clearer, revealing that the PSP will use the AVC decoder, which has a high encoding rate. This will allow the UMD to store up to two hours of DVD quality video. Sound is also taking a high place on the system's feature list. The PSP will feature reconfigurable DSPs which can be rewritten allowing for support for the latest sound technology. Sony announced today compatibility with the ATRAC3 plus format along with AAC and mp3. In addition, the system will support playback of 3D and 7.1 channel sound. On top of all this is Wireless Lan. The system will include as standard IEEE802.11 wireless LAN. Sony had originally intended to make this an option, but game creators were pretty adamant about its inclusion. Sony revealed no further details about the system's networking features, unfortunately. The PSP will, of course, play games as well. Sony will be tapping into its PlayStation heritage and including the familiar triangle, circle, X, square, start, select, L1 and R1 buttons on the system. These will be digital. In addition, the system will include a single analogue thumb pad. For a list of specs on the system, see just below this article. If you find yourself salivating at these specs, you're not alone. Unfortunately, Sony shared nothing but words today. A prototype of the PSP will debut at E3 of next year (May of 2004) with 2004's Tokyo Game Show (September of that year) expected to bring with it the unveiling of the system's game lineup. A worldwide simultaneous launch for the unit is expected for the fourth quarter of 2004.

Guest KoR Fungus Report post Posted July 29, 2003 Damn that sounds awesome. How much is this supposed to cost? Share this post Link to post Share on other sites
Guest MarvinisaLunatic Report post Posted July 29, 2003 So basically its a portable Mp3/Video system first, and the games are just sort of an afterthought.. Ok then. Share this post Link to post Share on other sites
Guest Brush with Greatness Report post Posted July 30, 2003 So when I looked to the side and saw "Last post by..." Marvin is a Lunatic, something told me that he would be saying something negative. Funny how that is. Slap a Nintendo label on it and he'd be all over it like flies on shit. Share this post Link to post Share on other sites
