Intel announces energy-efficient quad-core processors that consume 50-watts of power

Intel today released two new energy-efficient quad-core Xeon processors for multi-processor servers. The new Intel Xeon L5320 and L5310 operate at 1.86 GHz and 1.60 GHz respectively. Energy-efficient Xeon models consume 50-watts of power, which translates to 12.5-watts of power per core. Intel’s regular quad-core Xeon 5300-series consume 120-watts of power.

Energy-efficient Intel Xeon L5320 and L5310 processors are nearly identical to their higher-clocked counter parts. The energy-efficient models have 8MB of total L2 cache, 4MB of shared L2 per pair of cores, as with other Xeon 5300-series models. Front-side bus of the Xeon L5320 and L5310 are clocked at 1066 MHz, similar to the normal Xeon E5320 and E5310.

Pricing for the energy-efficient Intel Xeon L5320 and L5310 is $519 and $455 in quantities of 1,000, respectively. Intel Xeon L5320 and L5310 processors are drop-in compatible with Intel’s Bensley server platform.

RE: Do low power CPUs over clock better?

They dont OC better per default. They are just running at a lower voltage. Sometimes using slower switching transistors that takes less power.

There was a person at the XS forum running a C2D at 0.88V at stock speed of 2.4Ghz. I doubt it used over 15-20W. So low voltage or ultra low voltage is the key.

I wish we could hear more often about undervolting.
