    The PS3's 3.2 GHz Cell processor, developed jointly by Sony, Toshiba and IBM ("STI"), is an implementation to dynamically assign physical processor cores to do different types of work independently. It has a PowerPC-based "Power Processing Element" (PPE) and six accessible 3.2 GHz Synergistic Processing Elements (SPEs), a seventh runs in a special mode and is dedicated to OS security, and an eighth disabled to improve production yields. The PPE, SPE's and other elements ("units") are connected via an Element Interconnect Bus which serves to connect all of the units in a ring-style bus. The PPE has a 512 KiB level 2 cache and one VMX vector unit. Each SPE is a RISC processor with 128 128-bit SIMD GPRs and superscalar functions. Each SPE contains 256 KiB of non-cached memory (local storage, "LS") that is shared by program code and work data. SPEs may access more data in the main memory using DMA. The floating point performance of the whole system (CPU + GPU) is reported to be 2.18 TFLOPS[72]. PlayStation 3's Cell CPU achieves 204 GFLOPS single precision float and 15 GFLOPS double precision. The PS3 will ship with 256 MiB of Rambus XDR DRAM, clocked at CPU die speed.

    The Cell microprocessor allows programmers to assign SPE's different work by running individual programs on them. Programmers may also arrange data flow in different ways, for example using parallel, pipelined or streamed processing data flow models. As an example for parallel processing performance gains, one core could work on decoding and multiplexing audio, another core may perform computations on realistic projectiles ballistics, while another might govern the activities of the main character. The programmer still has three more cores not yet assigned but the only remaining tasks are to collect the work performed and display the results on the screen. Since the program code on each SPE core is executed from its local store memory, much more Element Interconnect Bus bandwidth is available to transfers of work data. An obvious downside to this is that there is a 256 KiB size restriction on SPE programs, which may present a challenge for certain programming tasks.

    The Graphics Processing Unit is based on the NVIDIA G70 (previously known as NV47) architecture, which focuses on maximizing per-pixel computation in favor of raw pixel output. The GPU will make use of 256 MiB GDDR3 VRAM clocked at 700 MHz. The GPU has access to the XDR main memory as well.

    The PS3 supports standard and HDTV resolutions (up to 1080p60) and connectivity options (such as HDMI 1.3 [74] and component video)[75]. In terms of audio, the PS3 will support a number of formats, including 7.1 digital audio, Dolby TrueHD, and others. For the optical drive, a wide variety of DVD and CD formats are supported, as well as Blu-ray Disc. A 20 GB / 60 GB 2.5" SATA150 hard disk is pre-installed and coupled with Linux. In the 60 GB configuration, flash memory can also be used — either Memory Stick, CompactFlash, or SD/MMC. For communication, the PS3 will have one gigabit ethernet port, four USB 2.0 ports, and will support Bluetooth 2.0 EDR.

    Compared to the protype version, the console has many more ventilation holes, and uses heat pipes; Sony claims the system is as quiet as a slim PS2. Physically, the PlayStation 3 is approximately 5 kg (11 lb), 9.8 cm × 32.5 cm × 27.4 cm (3.9 in. × 12.8 in. × 10.8 in.). The power supply is built into the console and a standard 3-pin IEC connector is present at the base of the console. The current Japanese console is marked as 100v externally, but internally as Universal 100V-240V and works within Europe and worldwide.

    The PlayStation 3 uses a version of the NetFront browser by Access Co. as its internal web browser. It is the same browser used in the PSP (Sony-branded NetFront 2.81) with the same interface, menus and virtual keyboard. Its user agent string is cloaked, falsely reporting as Mozilla/5.0 (PLAYSTATION 3; 1.00).

    I agree with adidas. PS2 for casual gaming for older games, or PS3 for new games and better features. As for the second part of your question, adidas already answered that in the beginning, and I quote: "...(new PS3 slim models do NOT play PS2 games)."
