New PowerVR chip may give Apple's future iPhone HD, OpenCL
Hidden among the many announcements at the Consumer Electronics Show in Las Vegas is a new PowerVR mobile graphics chip that could power advanced 3D, HD video and even general computing on an eventual generation of iPhones.
Imagination Technologies has quietly slipped out word this week of a new mobile chip known as the PowerVR SGX543. The silicon is the company's fifth generation of graphics accelerators for cellphones and other handhelds and contains a much more efficient instruction set with particular optimizations for rendering graphics shaders, or the visual effects that apply to pixels onscreen and geometry in 3D views. Imagination reckons that its new technology is about 40 percent faster for "shader-heavy" software and can push as many as 50 percent more triangles when handling 3D. In practice, the technology is powerful enough to push 35 million polygons per second and 1 billion pixels per second and can thus easily drive HD resolution video output, including when 3D is involved. Moreover, the new SGX chip is very efficient and very scalable, according to the company. That same performance is achievable at a clock speed of just 200MHz, making it relatively power-efficient, but can be improved further still with new multi-core support that would let a device maker join two or more cores together to ramp up the speed in the devices with the physical space and battery power to use the hardware. But the most important aspect of the PowerVR chip may be the universal nature of its processor. The GPU is capable of handling Apple's now open and virtually finished OpenCL standard for speeding up general computing and letting it move to non-CPU technology such as graphics chips, even on mobile devices. Imagination has lately been hiring OpenCL engineers to ensure its hardware supports the compute standard. As of the present, it's unknown whether or not the OpenCL move is being made with Apple's iPhone and iPod touch in mind; the existing iPhone has used an older PowerVR MBX core for its graphics in two generations and isn't currently known to be making the leap to SGX. However, Apple is now a major PowerVR licensee and has boosted the number of shares it holds in Britain-based Imagination, all but committing iPhones to using future PowerVR advancements. SGX543's inventor pledges to provide more information about the product at the Multicore Expo in March. |

It's going to go nicely with the Quad Core ARM Cortex MPA9

Another slightly misleading post from AI.. This may be nitpicking to some, but this post makes it appear that the PowerVR "SGX" line of graphics processors was just announced.
In fact, the only thing that was newly announced at this CES was the specific "SGX543" unit. The PowerVR "SGX" line has been known about for a few years and has just recently (finally!) been integrated into system-on-a-chip platforms from T.I., Qualcomm, etc. It was actually demo'd at the ARM tradeshow in 2006. Unfortunately, unlike the PC market, the embedded moves slow in getting new stuff to market. The ARM Cortex-A8, which will most likely find it's way into the new iPhone, was also licensed since 2006. |

I still don't believe we'll see the fruits of OpenCL and the real reasons for Apple's investment in the company until the 2010 iPhone. This year's new iPhones (maybe new form factor) may have new processors but it just seems to quick that they'd get the OpenCL benefit.

Anyways, having worked for several years in the smart phone development industry and with those SOCs, I believe that people seriously underestimate the amount of work that goes into getting new platforms like the iPhone or the Palm Pre up and running, both HW and SW. It is absolutely mind boggling how complex those devices are under the hood and to make everything work smoothly and without glitches is a herculean task. |

All true but does anybody here not think that Apple has been working a SoC for awhile
Quote:
If you buy any of the above you could see where a SoC research and development for the next iPhone processor has likely been under development for at least two and a half years. So yeah this a big undertaking but one that likely has been underway for a long time. A new device with the fruits of this effort inside is very likely this year. Now I'm not going to guess as to what cores and GPUs it will have but you can't dismiss recently revealed tech. From Apples standpoint what ever they offer up will be faster and likely lower power. So maybe it ends up being nothing more than an incremental iPhone upgrade. The other thing is that Apple has varying needs with respect to handhelds so I still have this idea that there are more than one SoC underway. To this many will respond that it is way to expensive. While not cheap I do believe Apple has the device volume to justify the effort. If you look at the iPhone Nano as a real product it should be obvious that it simply won't have the battery power to drive a high performance chip nor the screen realestate to make it worthwhile. So an Appple chip would go into a low end iPhone and iPods. The higher end devices would get a faster more robust device. So is a custom SoC from PA possible this year? Certainly it just might not be what everybody wants. Dave |

This chip is going into Apples' next "Netbook"
The first generation may not have the SGX that is capable of multi-core, but it might.
Actually, calling it a Netbook would be misleading. Just imagine a multi-core Netbook capable of running hi-res games, running next-generation, Javascript-heavy web 2.0 apps, and running current generation iPhone apps. (...and imagine a slightly updated version of iPhone OS X on it) |

What we're seeing is a return to custom parts yet as you say the volume necessary to warrant going down that path. No one understood the PA Semi acquisition at first. All the press could think of was "Apple's going to use the PWRefficient chip in iPhones" which was laughable. If it's not clear to people where the next gold rush is let's make it clear. It's mobile computing and I'm not talking about laptops. I 4 years the nation will see Wimax and LTE vying for customer dollars and providing wireless bandwidth that is faster than many home broadband connections. Retail stores will feel the pinch. I think the only music retailers to survive will be the larger Brick n Mortar. Content will be available from thousands of sources in some areas 24/7 Apple is investing in Cloud (yeah yeah I know) infrastructure and aligning with ARM and Imagination to deliver low cost devices. OS X is being made more efficient (removing PPC and Carbon) and smarter about hardware (GrandCentral and OpenCL) Apple has 25+ Billion and momentum to position themselves. |

Regarding Carbon, while the UI stuff is being retired, Carbon is still used to implement a lot of OS functionality (Audio, the file system, etc). It's going to be a while before enough of Carbon is exposed by CoreFoundation-like frameworks to even deprecate it (and even then it might still run a lot of the same code), so don't expect it to be gone in 10.6 or even 10.7. |

Something folks here [most assuredly due to their lack of OEM background experience] doesn't seem to realize is that most announcements come after 18 months of partner development efforts. |

Carbon is certainly going to be around but the train has moved on. 64-bit Cocoa or bust. I'm not a Cocoa is God guy but I want one major framework to be promoted for clarity's sake. I do find it intriguing that people assume that a press release is the first time licensee get word of a new product. I imagine designing a SoC is a lot like designing software. You work on alpha and beta product and tweak your design all the way up to the final release. |

Guesses are that we'll see a PowerVR SGX 53x series mated to a faster ARM core in the next revision. The 2010 iPhone will be a powerhouse. We could see a custom chip based on ARM Cortex processing and PowerVR SGX 54X chips. Apple could also deliver a Netbook class processor in 2010 with a ARM Cortex MPA9 and a PowerVR SGX 54x running full on OS X. That would be a quick little device. |

I'm not sure what you are trying to say here.

It should be noted that Apple has the volume when iPhone and tablets are combined. Easily in fact as the volume there far outstrips the computer line up. Quote:

It is not just Mobile Me either, as one of the original motivators was iTunes. If Apple gets involved similarly with books and magazines we will be all set. Quote:

This is an interesting consideration, does focus on one ISA make the Mac better.
Quote:
As to building an OS for different ISAs well that in an of itself seems to be a good thing. It certainly has helped bring Linux to the point it is today. Then again the Linux crowd doesn't do fat binaries. My position is that supporting Mac OS on differrent ISAs is a positive thing for Apple in the same way it is positive for the Linux crowd. In Apples case a portable OS makes for the flexibility to do things like iPhone. I would be surprised if we don't see MacOS embedded in more products from Apple in the future. More importantly the cross building and optimisations act as fertilizer to grow a better mainline Mac OS kernel. Note I'm playing a little loose here with the term Mac OS as we all know the portable devices are different. Quote:
. People should realize that these are major deals or developments that take a lot of time to get ready for public consumption. Further, iPhone is basically generation ONE and was developed over a long period of time. Due to gen one performance issues I would suspect that the process to develop a custom chip started soon after the engineering started on the iPhone. I'm really holding out for mid summer but it could be earlier than that. The only problem is guessing at what the new products will be. A smaller iPhone makes a lot of sense as does a larger. That is just dedicated iPhone's, the potential for other products is huge. Personally I'm all for the larger iPhone. As to a tablet device I'm still thinking they need to start at paperback book size and go from there. Dave |

is going to have more grunt than what is currently in the OMAP3 but i'm assuming it'll also come with a higher power usage penalty. I think you're right about that Finnish company. They love power. It kind of sounds like the SGX 543 would be nicely paired with a MP Cortex-A9 for a quick MID/Netbook/UMPC or whatever you want to call it. |

I think right now Nokia only make use of openGL in the ngage console but with OMAP3 and support for 2.0 they will surley make more use of it in the UI itself as the PalmPre has. Not to mention the ability for HD playbak also. I'm sure Apple have something good in store for us. I'm just too impatient that's all.
