  1. 1. December 29, 2011 batteryfast.co.uk CES 2012: What to Expect From CPUs Crossing the Sandy Bridge W hat does the future hold for processors? We expect more speed and less power consumption, lurking behind unassu- ming code names such as Ivy Bridge, Piledriver, and Tegra 3. As the brains of most every modern computing gadget, the central processing unit or CPU is an in- dispensable part of every desktop, laptop, phone, or tablet. The processor crunches the numbers and assigns the tasks, and it’s one of the chief pieces of hardware that determine how thick your laptop is or how long your phone’s battery will last. Every year, these slabs of silicon get smaller, stron- ger, and more energy-efficient. That’s good news for gadget mavens, as devices become faster, lighter, and generally more impressive as a result. Next In the desktop and laptop markets, there are two year will be no exception. In this article, I’ll look at major players: Intel and AMD. Of the two, Intel hashttp://www.batteryfast.co.uk/battery-technology/ces-2012-what-to-expect-from-cpus/ what’s expected from Intel, AMD, and Nvidia. It’s a gained more traction this year, bringing a number bit too soon to tell how things will shake out–expect of powerful, popular components to market–with big announcements from the CES tech trade show the promise of much more to come in the next year. in January–but I’ll try to fill in some of the blanks. Intel operates on what it calls a “tick-tock” cycle. With every “tick,” Intel introduces a new manu- facturing process. In 2010, Intel’s “Clarkdale” des- ktop processors reduced the company’s Nehalem microarchitecture to 32 nanometers, delivering im- proved performance and energy savings. With every “tock,” Intel introduces a new microarchitecture. In 2011, we got Sandy Bridge CPUs, which deliver superior performance to their Clarkdale predeces- sors while cutting power costs and improving the integrated graphics performance. We’ll see the next “tick” in 2012, when Intel shrinks the Sandy Bridge microarchitecture down to the 22-nanometer process. The resulting new CPUs, Love this PDF?

That means you’ll see laptops that provide better battery life Smaller Is Better without sacrificing speed, as well as faster desktops that are easier on your utility budget. Under the Hood Intel’s Desktop Platform RoadmapIntel has offered no confirmation of what the Ivy Bridge lineup will look like, but leaked reports obtained by Xbit Labs give some information on the new processor line’s naming convention, as well as its CPU frequencies. The new CPUs will purportedly follow the standard naming convention for Intel’s Core processors, fal- ling into the 3000 series (Sandy Bridge was the 2000 series). A refresher: Traditionally Intel divides the Core plat- form into three segments–Core i3 at the low end, Core i5 for the midrange, and Core i7 at the high end. Following that designation is a model number. You may also see a suffix at the end of the model num-http://www.batteryfast.co.uk/battery-technology/ces-2012-what-to-expect-from-cpus/ ber: K for unlocked processors, S for “performance- Most of the information we have about Ivy Bridge optimized” processors, or T for “power-optimized” comes from the Intel Developer’s Forum held earlier processors. The S and T variants are generally for this year, plus the occasional leaked PowerPoint OEM use only–expect to see them in desktops and presentation. Of primary importance is Intel’s die laptops on retail shelves. An unlocked, higher-end shrink, which moves from the 32-nanometer process Ivy Bridge CPU, for example, could be named the to the 22-nanometer process. Switching to a smaller Intel Core i7-3770K. die size allows processor manufacturers to create chips that draw less energy. We also know that Ivy Bridge will be compatible with the LGA 1155 socket–great news for Sandy Bridge Earlier this year Intel unveiled the 3D “tri-gate” owners, who may not need to buy an entirely new transistor technology that it has implemented to motherboard to upgrade. And if you just dropped a make the transition to the 22-nanometer process. few hundred dollars on Intel’s Sandy Bridge Extreme The new transistors are smaller, faster, and more Edition processor, don’t worry: When I met with power-efficient, and will be key to the performance Intel representatives, they told me that Ivy Bridge gains that Intel claims we’ll see with Ivy Bridge. Extreme Edition will use the LGA 2011 socket, so you too have a clear upgrade path. But what does all of that mean for you? Simple: An Ivy Bridge CPU will supply performance similar to Love this PDF?
