  • next generation PlayStation - and its Xbox competitor - feature eight-core CPUs clocked at 1.6GHz according to sources trusted by Digital Foundry
  • AMD Jaguar tech
  • laptop/mobile processors
  • Orbis also features Radeon HD graphics hardware - ?"Pitcairn" design - the Radeon 7970M?
  • At this time we cannot confirm the make-up of the Durango graphics hardware


This is all followed with a bunch of info to support their claims.



It's pretty funny how AMD CPUs are getting trashed like crazy by PC enthusiasts yet seems like they will be all the rage with consoles.



Hot dang. I don't know which of these rumors are true but the more I read them the more I see myself getting this thing at launch. XD



 

Playstation = The Beast from the East

Sony + Nintendo = WIN! PS3 + PSV + PS4 + Wii U + 3DS


Both the next generation PlayStation - and its Xbox competitor - feature eight-core CPUs clocked at 1.6GHz according to sources trusted by Digital Foundry. The main processor architecture driving both consoles is said to be derived the new "Jaguar" technology currently in development by Intel's arch-rival, AMD. These are low-power processor cores designed for the entry-level laptop and tablet market, offering an excellent ratio between power consumption and performance. The PC Jaguar products are set to ship later this year in a quad-core configuration - next-gen consoles see the core count double with some customisations added to the overall design.Married to the eight-core processor, Orbis also features Radeon HD graphics hardware. We'vepreviously suggested that AMD's mobile "Pitcairn" design - the Radeon 7970M - could be a strong basis for a next-gen console graphics core in terms of power consumption and die-size. Running at 850MHz and featuring 20 of AMD's "Graphics Core Next" compute units, our information suggests that Orbis shaves off 10 per cent of that number, offering up 18 CUs in total, and sees a mild downclock to 800MHz. Incorporated into a design dedicated to cutting-edge visuals and gameplay, this hardware has some serious potential.It is perhaps more than coincidence that these specs offer up the 1.84 teraflops metric for the Orbis GPU that was mooted yesterday, assuming that the figure is calculated in the same way that it is for AMD's current "Graphics Core Next" range of products. At this time we cannot confirm the make-up of the Durango graphics hardware - rumours have circulated for quite some time that it is some way behind Orbis, but equally there has been the suggestion that the GPU itself is supplemented by additional task-specific hardware. We could not confirm this, but an ex-Microsoft staffer with a prior relationship with the Xbox team says that two of these modules are graphics-related.

PlayStation Orbis: Spec highlights

Distilled down to the fundamentals, these are the details we can share about the technological make-up of the next generation PlayStation.CPU: Eight-core AMD processor running at 1.6GHzGraphics core: Radeon HD hardware, 18 compute units at 800MHzAdditional hardware: GPU-like Compute module, some resources reserved by the OSSystem-on-chip codename: LiverpoolMemory: 4GB GDDR5, 512MB reserved by the OS

However, there's a fair amount of "secret sauce" in Orbis and we can disclose details on one of the more interesting additions. Paired up with the eight AMD cores, we find a bespoke GPU-like "Compute" module, designed to ease the burden on certain operations - physics calculations are a good example of traditional CPU work that are often hived off to GPU cores. We're assured that this is bespoke hardware that is not a part of the main graphics pipeline but we remain rather mystified by its standalone inclusion, bearing in mind Compute functions could be run off the main graphics cores and that devs could have the option to utilise that power for additional graphical grunt, if they so chose.Previous rumours have suggested that Orbis runs its CPU cores along with some graphics hardware inside a standalone, custom AMD Fusion core with a separate, discrete GPU. Our sources suggest otherwise - all of these elements are embedded into the same piece of silicon, and we can confirm that the internal codename for the processor is indeed "Liverpool", as was mooted some time ago. Sony does have some form here for pushing the envelope - PlayStation Vita represents the only mobile GPU processor that combined quad-core ARM Cortex A9s with the PowerVR SGX543 MP4. Even on the power-hungry iPad 3, Apple stuck with dual-core CPU architecture at the same 45nm fabrication node.The news that so much processing power is packed onto a single processor is highly significant to the point where credibility could be stretched somewhat. However, helping to explain matters is the make-up of AMD's Jaguar tech - each core occupies just 3.1mm2of die-space at the 28nm fabrication standard. Factor in L2 cache, and the overall CPU component could be as little as 75-80mm2 in total. That's in contrast to the 235mm2 of the launch PS3's Cell processor and the 240mm2 of the Emotion Engine chip inside the original PlayStation 2 - neither of which factored in the separate graphics hardware, which in both cases was even larger. By our reckoning, the more efficient eight-core set-up still leaves plenty of space for integrating the main GPU onto the same die, with space to spare. This offers up significant production cost savings and brings down overall power consumption."Orbis has a singular focus on delivering high-end performance without breaking the bank - our take on the specs is that this is a machine built to last with a huge amount of potential."

AMD is in a serious need of money so they probably offered a lot cheaper deal for Sony and MS than Intel or IBM.



so im to tired to read the article, but if they are right, how powerful are these things going to be?



The worst part of next gen: waiting for it to arrive!



Xbox OS 3GB, that sounds like overkill

Yeah, AMD is quite competitive on price from the get go.

I like AMD CPUs myself... Most PC game benchmarks that favor Intel tend to be very biased for single threaded performance. If you run Antivirus, while streaming a video somewhere else and playing Crysis 2, AMD 8 core will be better than Intel's. And I think that's what these consoles are going for...multitasking multimedia machines.
