+ Texture buffer bandwidth: 9.6 GB/s

+ Frame buffer bandwidth: 38.4 GB/s

o DRAM Bus width: 2560-bit (composed of three independent buses: 1024-bit write, 1024-bit read, 512-bit read/write)

o Pixel Configuration: RGB: Alpha:Z Buffer (24:8, 15:1 for RGB, 16, 24, or 32-bit Z buffer)

o Dedicated connection to: Main CPU and VU1

o Overall Pixel fillrate: 16x147 = 2.352 Gpixel/s (rounded to 2.4 Gpixel/s)

+ Pixel fillrate: with no texture, flat shaded 2.4(75,000,000 32pixel raster triangles)

+ Pixel fillrate: with 1 full texture(Diffuse Map), Gouraud shaded 1.2 (37,750,000 32-bit pixel raster triangles)

+ Pixel fillrate: with 2 full textures(Diffuse map + specular or alpha or other), Gouraud shaded 0.6 (18,750,000 32-bit pixel raster triangles)

o GS effects: AAx2 (poly sorting required)[36], Bilinear, Trilinear, Multi-pass, Palletizing (4-bit = 6:1 ratio, 8-bit = 4:1)

o Multi-pass rendering ability

+ Four passes = 300 Mpixel/s (300 Mpixels/s divided by 32 pixels = 9,375,000 triangles/s lost every four passes)[37]

* Audio: "SPU1+SPU2" (SPU1 is actually the CPU clocked at 8 MHz)

o Sound Memory: 2 MB

o Number of voices: 48 hardware channels of ADPCM on SPU2 plus software-mixed channels

o Sampling Frequency: 44.1 kHz or 48 kHz (selectable)

o Output: Dolby Digital 5.1 Surround sound, DTS (Full motion video only), later games achieved analog 5.1 surround during gameplay through Dolby Pro Logic II

* I/O Processor

o I/O Memory: 2 MB

o CPU Core: Original PlayStation CPU (MIPS R3000A clocked at 33.8688 MHz or 37.5 MHz)

o Automatically underclocked to 33.8688 MHz to achieve hardware backwards compatibility with original PlayStation format games.

o Sub Bus: 32-bit

o Connection to: SPU and CD/DVD controller.

 

* Interfaces:

o 2 proprietary PlayStation controller ports (250 kHz clock for PS1 and 500 kHz for PS2 controllers)

o 2 proprietary Memory Card slots using MagicGate encryption (250 kHz for PS1 cards, up to 2 MHz for PS2 cards)

o Expansion Bay (PCMCIA on early models for PCMCIA Network Adaptor and External Hard Disk Drive) DEV9 port for Network Adaptor

o Modem, Ethernet and Internal Hard Disk Drive (single IDE/ATA channel, possible to hook 2 devices to.)

o FireWire (only in SCPH 10xxx – 3xxxx)

o Infrared remote control port (SCPH 5000x and newer) — IEEE 1394 port removed and Infrared port added in SCPH-50000 and later hardware versions.

o 2 USB 1.1 ports with an OHCI-compatible controller.

 

* Disc Drive type: proprietary interface through a custom micro-controller + DSP chip. 24x speed (PlayStation 2 format CD-ROM, PlayStation format CD-ROM), 4x (Supported DVD formats) — Region-locked with anti-copy protection. Can't read Gold Discs.

 

* Supported Disc Media: PlayStation 2 format CD-ROM, PlayStation format CD-ROM, Compact Disc Audio, PlayStation 2 format DVD-ROM (4.7 GB)(some games on DVD9 8.5 GB), DVD Video (4.7 GB), DVD-9 (8.5 GB Double-Layer). Later models (starting with SCPH-50000) are DVD+RW, and DVD-RW compatible.

Senas geras PS2, dar po siai dienai kartais ji trumpam isijungiu. 10 metu, o zaidimai visai playable yra long live ps2!

tik zaisti ir zaisti dar su PS2, su next gen kartais nebuna ka veikti tikrai,ar pvz parodyt draugam,ar draugem ,zmonem kurie zino nuo senu geru laiku FF serija ,ar MGS,ar GT , ar kruva rpg,vaikam platformu ir pan.ant next gen to nerasi,ir jau deje niekas nekurs tokiu zaidimu,jie liks visam laikui su PS2.as siaip dar siemet zadu isigyti PS2 ir jam LCD ekrana,kad butu toks kaip ir portable biski,na namie,o del zaidimu tai as neturiu kartais ka losti ant next gen gal,bet ant PS2 visada yra ka losti.kad ir tuos pacius zaidimus,tas nesvarbu jie vel zaidziasi labai gerai ir maloniai.ir dar zaisis ilgai,na kol kokia nauja sony portable konsole neemuliuos ps2 zaidimu.

be to zmonem kurie nera tokie geimeriai kaip mes,jie labiau noretu pamatyti kaip yra zaidziami tie jau klasika tape ps2 hitai.,bet jime visiskai nera idomus tie nauji net gen shooteriai.
