The PlayStation 3 (PS3) (Japanese: プレイステーション3) is Sony's seventh generation era video game console in the market-leading PlayStation series. The PlayStation 3 is slated for release in 2006[2]. Specifically, Sony representatives have informed video game store clerks to expect a North American shipment in Summer 2006, more narrowly defined as "somewhere between June and September." It is the successor to the PlayStation 2 and will mainly compete against the Nintendo Revolution and Xbox 360. Sony has announced that the PS3 will be backward compatible with earlier PS1 and PS2 games. At the moment, little more is known in public about the PS3 apart from its hardware specifications and reports that it will be based on open APIs for game development.

History

The PS3 was officially unveiled on May 16, 2005 by Sony during the E³ conference, where the console was first shown to the public. A functional version of the console was not at E³ or the Tokyo Game Show in September 2005, although some demonstrations were held on devkits and videos of soon-to-be released games created to run on systems with the same specs as the PS3 were presented, such as Metal Gear Solid and Killzone 3.

Cost and release date

Wikinews has related news:

The system's retail price is not known.[3][4] Sony Computer Entertainment president and "father of the PlayStation" Ken Kutaragi points out "It'll be expensive" and "I'm aware that with all these technologies, the PS3 can't be offered at a price that's targeted towards households. I think everyone can still buy it if they wanted to," said Kutaragi to a mostly Japanese crowd. "But we're aiming for consumers throughout the world. So we're going to have to do our best [in containing the price]". In contrast Kazuo Hirai, president of Sony Computer Entertainment America, says the PS3 will not be expensive and that it will be competitively priced against the Xbox 360.[5]

In the same magazine, Ken Kutaragi was interviewed, and expressed little concern over the PS3's possibly high launch price, believing that customers would be willing to pay extra for a superior product, as they had in the past for the original PlayStation (¥39,800 vs. 12,500 for the Super Famicom).

Sony office press releases indicate a 2006[6] launch. Sony Blu-Ray standalone players are to be released early summer[7]. It is likely that standalone players will be released prior to PS3. The inquirer web magazine which is more often right than wrong talks about internal Sony developement: http://www.theinquirer.net/?article=28879

Manufacturing costs

Merrill Lynch Japan estimates the PS3 manufacturing costs at 54,000 yen (U.S. $494) to make, not including labor, and its selling price at $399[8]. For the consumer this means one should be able to buy a PlayStation 3 at a lower price than its actual manufacturing cost. Although manufacturing costs for Blu-Ray and the cell are unknown, it is safe to say like all new systems, they will lose money from the first year. The nature of pricing a video game system is to sell as many games possible.

Hardware specifications

A simple comparison of the system architectures appears to indicate that the floating point capability of the PS3 is better than that of the Xbox 360. This comparison is based on the combined floating point capacity of the Cell microprocessor and the RSX GPU in the PS3 compared to the combined capacity of the Xenon CPU and Xenos GPU in the Xbox 360. The amount of completely programmable floating point capacity afforded by the Cell microprocessor for general-purpose tasks, like procedural content generation and game physics, is higher than the Xbox 360's CPU, while the floating-point performance of the two systems' GPUs, which are designed specifically for graphics rendering tasks, are somewhat closer to parity. These comparisons are based on estimates of theoretical maximum performance. Real-world performance for both systems will naturally be less, and the specifications of the PS3 may undergo major changes before the system is launched. Please see the section entitled overall floating-point capability for more details on this.

According to a press release by Sony at the May 16 2005 E3 Conference, the specifications of the PlayStation 3 are as follows. [9]

Central processing unit

3.2 GHz Cell processor:

  • 1 PPE core (PowerPC-derived)
  • 7 used SPEs (Synergistic Processing Elements) vector processing cores
    • 256 KB SRAM local memory for each SPE
    • 128×128-bit SIMD general purpose register files
    • 4 Integer units
    • 4 Floating point units
    • 25.6 GFLOPS (billion floating point operations per second)
    • 25.6 GOPS (billion integer operations per second)
  • 218 GFLOPS theoretical (billion floating point operations per second)
  • 218 GOPS total (billion integer operations per second)
  • 25.2 billion shader operations per second (100 billion with GPU)
  • 234 million transistors [10]
  • 213 million available transistors due to the one disabled SPE [11] [12]
  • 2.3 MB SRAM total (512 KB L2 cache and 1.79 MB SPE local memory)

Each chip includes 8 SPEs, but one is most likely disabled to improve yields and reduce costs

Graphics processing unit

Custom "RSX" or "Reality Synthesizer" design co-developed by NVIDIA and Sony:

  • Clocked at 550 MHz
  • 1.8 TFLOPS (trillion floating point operations per second)
  • Full high definition output (up to 1080p) x 2 channels
  • Multi-way programmable parallel floating point shader pipelines
  • 136 shader operations per clock
  • 74.8 billion shader operations per second (100 billion with CPU)
  • 33 billion dot products per second (51 billion dot products with CPU)
  • 128-bit pixel precision offers rendering of scenes with high dynamic range imaging

NVidia CEO Jen-Hsun Huang stated during Sony's pre-show press conference at E3 2005 that the RSX will be more powerful than two GeForce 6800 Ultra video cards combined. Nvidia has stated that the RSX will have a lot in common with the G70 architecture used in NVidia's GeForce 7 Series GPUs which were introduced in June of 2005, and since the G70 is also capable of carrying out 136 shader operations per clock, the RSX is expected to feature the same number of parallel pixel and vertex shader pipelines as the G70 (NVidia's top-of-the-line GeForce 7800 GTX 512 currently contains 24 pixel and 8 vertex pipelines), and clocked similarly to Nvidia's highest end PC GPU based on G70 (with speculation that the RSX chip will be reworked using the new G71 architecture topping 650-700 MHz) (again, the 7800 GTX 512 is clocked at 550 MHz, which is equivalent to the 550 MHz announced for the RSX). This places both the 7800 GTX 512 and the RSX at approximately 28% faster than the 256 MB 7800 GTX. An nVidia spokesperson was quoted in PlayStation Magazine as saying that the 7800GTX "shares a lot of similar inner workings with the PS3's RSX chip, only it (the 7800GTX) isn't nearly as fast (as the RSX)."

Memory

Theoretical system bandwidth

  • 25.6 GB/s GPU to XDR DRAM: 64 bits × 3.2 GHz
  • 22.4 GB/s GPU to GDDR-3 VRAM: 128 bits × 700 MHz × 2 accesses per clock cycle (one per edge)
  • 35 GB/s GPU to CPU (Aggregated 20 GB/s (write), 15 GB/s (read))
  • 5 GB/s System Bus (Aggregated 2.5 GB/s upstream and downstream)
  • 300 GB/s Cell EIB
  • 76.8 GB/s Cell FlexIO Bus (44.8 GB/s outbound, 32 GB/s inbound)

Since the RSX is connected to the XDR DRAM and GDDR3 RAM similar to a Turbo Cached GPU it can access both memory locations at the exact same time. This gives the RSX an effective 48GB/s when sending data to/from GPU and RAM.

Overall floating-point capability

Sony comparison of PS3 performance in FLOPS with Xbox 360.

In a slide show at their E3 conference, Sony presented the "CPU floating point capability" of the PlayStation 3's Cell CPU, and compared it to other CPUs. The presentation shows that one PS3 Cell CPU alone is capable of 218 GFLOPS, compared to the Xbox 360's Xenon CPU's 115 GFLOPS. In their official press release, the same statistic regarding the PS3 as a whole was reported to be over 2.1 TFLOPS. The figures are likely rounded estimations. It was unclear how these numbers were exactly calculated, possibly based on addition of the floating point capabilities of the processing units in the Cell CPU and those of the RSX GPU. The performance statistics given for the PS3 and XBox 360 in Sony's presentation were based on the theoretical maximum performance of the systems. Inevitably, real-world performance for both systems will be lower. Additionally, programmers may find it difficult, initially, to optimize their game engines to make the best use of the highly parallel architectures of both systems, further reducing real-world performance.

According to an in-depth report compiled by IBM, the theoretical peak performance of a single SPE is 25.6 GFLOPS. The seven SPEs in the PS3, in addition to the VMX unit in the PPE, would yield a total combined single-precision floating point performance of 218 GFLOPS (the same figure quoted by Sony). It should be noted that this figure is an estimate based on ideal, 100% efficient operation of the processor. In real-world applications, IBM expects that the Cell will achieve about 75.9% of its maximum performance (or roughly 165 GFLOPS). It is still expected that the floating-point capacity of the PS3 will significantly exceed that of the XBox 360, although it should be noted that Microsoft's console, due to its 3 symmetric fully featured processor cores (which are very similar to the Cell's PPE), may fare better on dynamically branching code, like that used for artificial intelligence.

Please note that all the above figures are based on the theoretical performance of components which may change considerably before product launch. Also, real-world performance WILL be less than the theoretical maximum. Finally, whether the PS3's advantage in floating-point performance will be readily apparent in games depends entirely on whether developers are able to effectively make use of the system's unique architecture.

It should also be noted that floating-point performance is a single-dimensional metric for comparing computers, and that many other considerations (including integer performance, memory size and bandwidth, etc.) determine the "overall" performance of a computer system. Floating point calculations are very important for graphics, multimedia, and game physics, but considerably less important for other tasks like artificial intelligence.

Controller

SCEI's press release indicates that controller connectivity to the PlayStation 3 can be provided via:

The design of the controller has been likened to a boomerang or a banana by many observers (or even less flattering likenesses). However, some suggest that the controller, while a little un-traditional in contrast to the DualShock and DualShock 2 controllers, might provide adequate comfort for extended hours of play. According to the Japanese video game publication Famitsu, Sony Computer Entertainment chief technical officer Masayuki Chatani said that the controller design is a "prototype, so there could be some small adjustments."

[15] In an interview with Edge, SCEE's Chris Deering echoed these statements by describing the E3 controller as "just a design study". Some people pointed that the controller bears a similar resemblance to the old Alps Interactive 3rd party controller which was originally made for the PlayStation. [16]

Unconfirmed reports suggest that the PS3 may in fact support the older DualShock 2 controllers, however, this is thought to be true due to the Playstation 3 striving to attain backwards compatibility. The number of ports to support such backward compatibility would most likely be limited to one, although this is also an unconfirmed rumour. The PS3's specifications, and E3 display units, don't support DualShock controller ports. Though Sony itself had previously admitted at this past E3 that the controller design for their PlayStation 3 console was not finalized, GameSpot believes any purported changes will not be substantial. They downplay a new rumor suggesting Sony will unveil a revamped PS3 controller at the Consumer Electronics Show in January 2006.

Interface

According to DevStation Conference, the PS3 will use the Xcross Media Bar already used in the PlayStation Portable and PSX devices.

Games in development

Main article: List of PlayStation 3 games

As of October 2005, there are already over 150 PS3 games announced by multiple developers and publishers, like SCEA, Electronic Arts, Konami, Namco, Capcom, Square Enix and many others. The actual number in development, though undeniably fewer, should still be very high.

Most developers have already announced games for the PS3. Some anticipated ones include Metal Gear Solid 4: Guns of the Patriots, Resident Evil 5, Devil May Cry 4, Shin Megami Tensei, Armored Core 4 , Unreal Tournament 2007 and Tekken 6. In the E3 2005 Press Conference, Sony showed some pre-rendered and some real-time videos of games in development with the codenames Eyedentify, Vision Gran Turismo and MotorStorm. Also shown at E3 was a video of Final Fantasy VII 's opening sequence remade in PlayStation 3 graphics, at the time recent to the show, Square Enix stated no plans for a remake. Square Enix is however listed for a Final Fantasy game along with 70 other Japanese developers during TGS 2005. Since they aren't working on a remake then this will most likely be Final Fantasy XIII. Controversial games developers Rockstar North have also hinted that they are planning the provisionally named Grand Theft Auto 4, primarily for the PS3. One of the most, if not the most anticipated PS3 game up to this point is Metal Gear Solid 4: Guns of the Patriots, which had its first trailer shown at the Tokyo Game Show 2005 event. At this time, only three games have been mentioned as PS3 launch titles: Lair from Factor 5 Warhawk from Incognito Entertainment, and Unreal Tournament 2007 from Epic Games. In the November issue of PSM Magazine, SCEA Chief Operating Officer Jack Tretton mentioned both Lair and Warhawk as launch titles, although Sony would not expand further on his comments. In the January issue of the same publication, it was stated that Epic Games is working hard to get Unreal Tournament 2007 ready for the proposed launch in Spring 2006. However, Epic stated in response that they are working to release the PC version first and that the PS3 version has no priority for release over the PC version.

Software development kit

Sony has selected several technologies and arranged several sublicensing agreements to create the software development kit for developers. The PlayStation 3, unlike the PlayStation and PlayStation 2 systems, is based on publicly-available application programming interfaces.

The list of open standards includes:

Sublicensed technologies includes:

The list of standards they are reported to be considering includes:

In addition, Sony recently purchased SN Systems, a former provider of Microsoft Windows based development tools for a variety of console platforms including the PlayStation 2, GameCube, PSP and Nintendo DS to create additional Linux development tools. Sony is providing developers with Linux toolchains where SN Systems will provide more customer-oriented Linux tools at an additional cost.

GNU/Linux

Ken Kutaragi confirmed that the PlayStation 3 will come with GNU/Linux as its operating system. [20]

IBM had quickly sent a series of improvements to the Linux developers mailing-list regarding the Cell processor, and has publicly presented a Cell based server running Linux kernel 2.6.12. [21] Since then IBM has begun to offer detailed information and tutorials for software development on Cell based systems including the PlayStation 3. [22]

Online services

Sony has recently revealed that the online service for the PlayStation 3 will use the same non-unified architecture as that of the PlayStation 2. In the latest issue of the Official PlayStation Magazine, Sony denied rumors that it would be implementing a centralized online service similar to Microsoft’s Xbox Live. Instead, online services for PS3 games will be decentralized and left up to individual game publishers. While this will give games publishers greater freedom in terms of what they are able to offer online, some say it may make it more difficult for Sony to control the quality of the online experience.

Decentralized online services means that there will be differant useface for each game depending on the developer however not necessarily multiple accounts to access online games via the PS3 service, however they will have the advantage of being able to choose which games or services they actually want.

Sony have yet to disclose to the public their plans for the PlayStation 3 online experience. The above should be regarded as speculative commentary, the basis of which is (reasonably well informed) discussion in the gaming press. It may well be the case that the PSP provides some sort of insight into exactly what sort of online experience Sony will be offering in 2006.

Region coding

PlayStation 3 games are unlikely to be region coded, according to Sony’s Australian managing director, Michael Ephraim.

Unlike its predecessors, the PlayStation and the PlayStation 2, the PS3 is tipped to allow gaming and movie playback from downloads or discs bought in any part of the world, rather than being limited to playing discs only from a specific region. The PS3’s support for HDTV standards was cited as one of the key reasons the company has stopped the practice of region coding.

According to Ephraim, “If you look at the fact that [the PlayStation 3] will support high-definition TV, which will be a global standard, there’s a good likelihood that it will be global region, as for example we’ve done with the PSP [PlayStation Portable].”

Sony's decision to stop region coding means consumers will be able to purchase PS3 games from anywhere in the world, which may turn out to be significantly cheaper than purchasing them exclusively from their home territory, or importing the system from Japan on launch.

Blu-Ray movies played on the PS3 will use a region code. The Blu-Ray region code will be different from DVD region code. [23]

Region code Area
1 United States, Canada, Mexico, South America, Japan and East Asia (excluding China)
2 Europe and Africa
3 China, Russia, and all other countries.

Backwards compatibility

Games

The PlayStation 3 will be compatible "on the chip" with PlayStation 2 and PlayStation games, without emulation. It still isn't known how Sony has achieved this (although Sony had developed a single-chip PS2 CPU/GPU solution, used in newer revisions of the "slim" PS2). Compatibility with PS2 online games and games designed for the hard drive support hasn't been elaborated upon. In a recent interview Ken Kutaragi stated that backwards compatibility will be achieved through a combination of hardware and software.

"Third-party developers sometimes do things that are unimaginable. For example, there are cases where their games run, but not according to the console's specifications. There are times when games pass through our tests, but are written in ways that make us say, 'What in the world is this code?!' We need to support backward compatibility towards those kinds of games as well, so trying to create compatibility by software alone is difficult. There are things that will be required by hardware. However, with the powers of [a machine like] the PS3, some parts can be handled by hardware, and some parts by software."

Peripherals

The PS3 will not be backwards compatible with some of the hardware peripherals of the PS2. For example, memory cards for PlayStation and PlayStation 2 will not work on the PlayStation 3 hardware. [24] Instead it was announced that the PS3 will use the Sony memory stick to save games. This means that the PS3 will not be able to use PS1 and PS2 memory cards; however, this will allow gamers to trade saved games over the Internet more easily.


Side note

The logo of the PlayStation 3 is in the same font as the logo of the Spider Man motion pictures.

Spider-Man 2 scenes were used in the E3 2005 Sony Press Conference demonstrating the console's capabilities.
