The Graphics Processing Unit, or GPU, of any modern computing device is an important piece of hardware that offloads 3D graphics rendering from the main processor. At CES 2010 last week, chip manufacturer Imagination Technologies may have spilled the beans on the GPU for the next generation of iPhones.

Imagination unveiled the PowerVR SGX545 GPU core design at CES, which is the only mobile phone GPU capable of OpenGL 3.2 and DirectX 10 level effects. The SGX545 also includes OpenCL support, which means that unused processing cycles on the chip can be used to offload work from the main CPU. The SGX545 is also multithreading-aware, and can provide an additional speed jump when used with multi-core processor designs such as the ARM Cortex-A9.

Imagination noted that they have produced a test chip for an unnamed "lead partner," which could very well be Apple. The Cupertino Kids have used PowerVR graphics in every iPhone and iPod touch, and many industry pundits believe the next generation of devices could be powered by a variant of the ARM Cortex-A9. Apple is also an investor in Imagination, having purchased a 9.5% stake in the chip manufacturer in 2008 and 2009. So it's very possible that the SGX545 could be churning out pixels in the next handheld you buy from the Apple Store.

Now that we have the actual ship date for Mac OS X 10.6 Snow Leopard (August 28th for those who haven't yet had a cup of coffee to wake them up), it's time to start thinking about what benefits you can gain from the newest member of Apple's cat family.

Apple has told us from the start that Snow Leopard is predominantly about streamlining both the size and speed of the operating system. Installing Snow Leopard should take about half the time of performing a Mac OS X 10.5 Leopard install, and it's expected that you'll gain about 7 GB of space back on your hard disk.

Snow Leopard is also bringing some new features to the table, including 64-bit support, Grand Central Dispatch's multicore support, and OpenCL, all of which can provide better performance for applications. There are amazing improvements to the Mac OS X Universal Access features, particularly for the vision-impaired. For those who use their Macs in a predominantly Windows office environment, the full built-in support for Exchange should make life much simpler.

TUAW would like to know what Snow Leopard feature you're anticipating the most, so we've come up with a short list for you to choose from in a poll. We'll use these results to provide you with detailed coverage about those features. If your favorite improvement or feature isn't on the list, leave a comment and tell us what you're excited about.

Tom's Hardware says that Apple will use NVIDIA's Ion platform in an updated Mac mini, and AppleInsider says it could also be used in an updated Apple TV.

NVIDIA's Ion platform is a low-cost, small-form-factor logic board that includes both an NVIDIA graphics processor and Intel CPU (among other things). According to AppleInsider, Ion uses the same 9400M chipset used in the new MacBook and MacBook Pro models. We knew that existing iMac and Mac mini models are already using the 9400M as part of the NVIDIA MCP79 platform. Either way, with the 9400M, full-screen HD decoding is built-in.

According to Tom's Hardware, the Ion package slated for use with the Mac mini includes an Intel Atom 330 processor. AppleInsider says that performance gains for a new Mac mini based on this platform could require OpenCL, a technology only available so far in builds of Snow Leopard.

Tom's expects the new Mac mini to arrive in March, while AppleInsider, says that it could arrive "this month." Fingers crossed.

The Apple TV, on the other hand, with its 1GHz CPU, would see a significant boost with Ion. The margins on the Apple TV are already tight, though, and adding more power could break the bank on Apple's "hobby" project. But what if the next-generation Apple TV and Mac mini were one and the same?

It's a floor wax! It's a dessert topping! Stop, you're both right.

Apple, not shy of shaking things up in the interface department, has been sitting on its laurels since the release of OS X earlier this decade. Sure, iPod changed the way we think about music and iPhone has completely turned the mobile phone industry around, but the Mac OS has been relatively static in terms of how users navigate within the environment since the release of 10.0. The good news, however, is that Apple is working on a way to change the way we interact with our systems.

MacRumors has uncovered information on a patent titled "Multi-Dimensional Desktop" which depicts a three-dimensional environment that looks somewhat like viewing a room from one end. The interface has methods for literally stacking files and minimized windows on top of one another as well as for dragging interface items along the multiple surfaces. An interface such as this would be fairly performance-intensive and the ratification of OpenCL along with the impending release of Snow Leopard could be just the shoes that need to drop for this to become a reality. There is no guarantee that this will ever be seen outside of Cupertino or the PTO, but if Apple does implement this interface design it would bring a whole new meaning to the term "wallpaper."

There's been quiet anticipation for the last 6 months for OpenCL (Open Computing Language), which is an Application Programming Interface standard allowing developers to take advantage of the power of Graphics Processing Units (GPUs) in parallel with multi-core processors. The result? Applications become much faster and responsive.

Apple announced in June that support for OpenCL would be built into Snow Leopard (Mac OS X 10.6). The Khronos Group, an industry consortium that creates open-standard, royalty-free APIs, put OpenCL on the fast track as a result, and announced yesterday that OpenCL 1.0 has been ratified by all of the consortium members.

Now that OpenCL has been officially blessed by the members of the consortium, could Snow Leopard be close behind? There has been speculation that the latest iteration of Mac OS X could be released as soon as Macworld Expo 2009 in early January. Snow Leopard, along with an announcement of quad-core iMacs, could throw a little fire into what is becoming an increasing chilly Expo. TUAW is attending Macworld Expo 2009 in force this year, so stay tuned for the latest news about Snow Leopard.
