What we know about the PS4 so far




Details on the processing specs of Sony’s PlayStation 3 successor, rumored to be codenamed Orbis, have been leaked by IGN, citing sources familiar with the company’s plans.

The custom chips to be used in the next-gen console are based on AMD’s A8-3850 APU and Radeon HD 7670 GPU, combining the performance of both integrated and discrete graphics processors. The AMD A8-3850 APU features a quad-core 2.9GHz processor with integrated graphics. It will work with the dedicated Radeon HD 7670 GPU, the HD 7670, and a DirectX 11-enabled card clocked to 1GHz with up to 1GB of dedicated VRAM. The HD 7670 is the same card that will reportedly be used in the Xbox 720, which is expected to compete head-to-head with the Orbis in discrete graphics. The Sony PlayStation Orbis is rumored to arrive in time for the holiday season in 2013. Select game developers have already begun working on titles for the console. The Orbis is said to not be backwards compatible with PS3 games and will be capable of displaying 4096 x 2160 resolution and play 3D games at 1080p.

Following continued reports last week that PlayStation 4 is to be based on AMD hardware and is being planned for a 2013 release, a  source has said Sony is aiming to get the machine to market ahead of Microsoft’s next generation Xbox.

The design goalposts for PS4, including specs, were in place at least two years ago, we were told. Our source said that Sony is “confident” it will have the console at market ahead of the next generation Xbox next Christmas. VG247 reported this morning that developers and publishers have been told that Xbox 720 will be released for Holiday 2013.

“Sony are completely in the belief that they have the jump on Microsoft this time,” they said. “You should be watching the timing of next year’s E3 keynotes, and who’s going to go first.” A second source said this morning that all next-generation systems will be in place “by 2014″. Sony has apparently already put its favoured partners in the frame as to PlayStation 4.

“Top line publishers already know about it,” our source said. “Developers working with publishers – like Ubisoft, for example – already know what’s going on. They’re already working on it.” While “most developers” will be fully briefed “by the end of this year,” some have been invited to events in May and June in the US.

Another source has told us more information is going to be issued about PS4 to developers under NDA in May. MCV reported earlier this year that both PS4 and Xbox 720 “will be shown at E3 2012,” but both Microsoft and Sony have both said nothing consumer-facing about the next generation will happen at the LA event this year.

Direct to drive

In addition, a rumour is circulating that PlayStation 4 will use DirectX as opposed to a proprietary Sony API. It was reported last week that PlayStation 4 will not be based on PS3′s Cell processor in any way, and will instead use standard AMD hardware. We were told today that Crytek was scaling its tech on the assumption that PS4 was going to be using a 24-core Cell processor as opposed to the eight-core unit in PS3. The studio was forced to halt development and start afresh when it was informed PlayStation 4 won’t be using Cell at all.

Indications are that PlayStation 4 will provide a development environment similar to that of the Xbox consoles and PC. In addition VG247 has been told that elements of Vita’s launch hardware were changed to ensure that PS4 and Vita will be able to connect in a similar style to Nintendo’s Wii U and its controller – due for release this year – with Vita’s being used to control PS4 games with both twin sticks and touch.

I just don’t see Sony going with an x86 CPU at this time. I can understand that AMD’s Piledriver will be similar in concept to the Cell but it’s not the same. Hopefully Sony will put a big chunk of XDR system ram in the PS4.

The successor to the PlayStation 3, apparently codenamed “Orbis,” will use an AMD x86 processor with an AMD “Southern Islands” GPU, according to rumors emerging last week. Xbox 360’s replacement, purported to be named “Durango”, is also rumored to use an AMD GPU—either a Southern Islands variant or an equivalent to a Radeon HD 6670—this time paired with a PowerPC CPU.

Though these rumors are thoroughly unconfirmed at the moment, they’re all well within the realm of plausibility. But if they prove true, the Orbis and Durango will be decidedly mid-range at launch when compared to top-of-the-line PC hardware. The Xbox 360, launched November 2005, and the PlayStation 3, launched November 2006, were both cutting-edge systems at their release. Their capabilities were unmatched by PCs of the time. If these rumors are to be believed, the eighth console generation won’t be a repeat of the seventh.

The stupendous seventh generation

The Xbox 360’s Xenon processor, a three-core six-thread PowerPC unit running at 3.2 GHz, had a theoretical peak number crunching throughput of 115 gigaflops. A contemporary Pentium 4 at 3 GHz had a theoretical peak of around 12 gigaflops when the system launched. The PlayStation 3 was in a similar situation; its Cell CPU, jointly developed by IBM, Toshiba, and Sony, had a theoretical throughput of 230 gigaflops. Contemporary Core 2 Duos topping out at 24 gigaflops at the time—and cost many hundreds of dollars to boot.

The GPUs found in these systems were not quite so impressive compared to those available in desktop systems at launch, but they were still high-end. Xbox 360’s Xenos was built by ATI, falling somewhere between the capabilities of its R520 (sold as the Radeon X1800 series, released in October 2005), and its R600 (retailed as the Radeon 2900 series, released in May 2007). The PlayStation 3’s Reality Synthesizer was designed by NVIDIA, as a slightly cut-down G71 (marketed as the GeForce 7900 series, released in mid-2006).

In short, the (theoretical) CPU performance of the current generation consoles was out of this world when they launched. Their GPUs went toe-to-toe with discrete cards costing as much as the consoles themselves.
