Intel Shows Off 'Sandy Bridge' Processors


Intel  kicked off its Intel Developer Forum with several demonstrations of its next generation "Sandy Bridge" chips that will help power a new generation of the company's processor family with integrated graphics built-in.

Officially dubbed 2nd Generation Intel Core Processors, Sandy Bridge chips are expected to start appearing in new PCs and notebook computers by early 2011.

Intel's Sandy Bridge chips will ship early in 2011

Locked down multipliers

Sandy Bridge CPUs without the K moniker will have both practically locked down multipliers as well as that BCLK locked to 100MHz.

Dave Salazar, of the Performance Benchmarking and Analysis Group at Intel, was happy to talk about the locked clocks. "It is somewhat limited...it has to do with the fact that basically the ring-bus architecture, the cache, the CPU, all sit on the same clock domain. Bear in mind that the PCIe now sits inside the processor as well."

This means that when you try and up the baseclock of the CPU it affects a far greater number of parts reliant on that same clock generator. "While certain aspects of the part have greater tolerances to moving the baseclock," Salazar explains, "others parts do not."

The machine quietly humming away behind closed doors in the Advanced Technology Zone of IDF was one of the K series chips, and with a very healthy overclock indeed.

We are bound by NDAs, and by worries that large men in black suits will carry us away in the night. That means we can't reveal exactly what the speeds of this chip were, but running on air-cooling alone the overclocked Sandy Bridge CPU was running far quicker than the 4.2GHz you can usually squeeze out of the supposedly analogous current gen Core i7 875K.
