IBM Unveils Energy-Efficient PowerPC ChipsBy Jeffrey Burt | Print
Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers
The PowerPC 970GX and 750CL chips offer better performance while consuming less power, IBM says.IBM is rolling out new PowerPC processors aimed at the embedded space that are designed to improve performance while consuming less power than their counterparts.
The new chips illustrate IBM's commitment to building processors that do not rely solely on speed bumps for performance improvements, but also are energy-efficient, said Ron Martino, director of Power architecture solutions for IBM's Technology Collaboration Solutions unit, in East Fishkill, N.Y.
"It's becoming a very big issue," Martino said, referring to power consumption and leakage in chips. By introducing these low-power processors, IBM is "giving the customer choice," he said.
The 750CL is more energy-efficient than its predecessors, Martino said. The current 750CX and 750GX are in the range of 10 to 14 milliwatts per megahertz, he said, while the 750CL ranges between 3 and 7 milliwatts per megahertz. It's aimed at such areas as networking, storage and multimedia.
The 970GX offers a 1MB Level 2 cachetwice the size of the 970FXruns between 1.2GHz and 2.5GHz, and also targets communications and storage workloads, as well as multimedia and graphics-based devices.
The 750CL is sampling now, while the 970GX is available immediately.
IBM also unveiled the CPC965 companion chip for the 970 series, which is designed to offer I/O connectivity while consuming less power than other bridge chips. Samples for the companion chip will ship in March 2007.
IBM also introduced the 460 core series, including the 460s synthesizable core, which allows designers to select the size of the L1 and L2 cache and processor local bus depending on what's needed for their work.
All three coresincluding the 464FH H90 and 464 H90have low-power capability, which means they offer essentially better performance than their predecessors, with better energy efficiency and support for a wide range of embedded applications.
