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.

PSU maker PR FUD sure works great.

Check out silentpcreview.com. I know how PSUs work and I know what are realistic power figures. The 80% efficiency quess is optimistic. It also could be around 75% thanks to 115V grid. High end power supplies peak around 85% and usually can't exceed 80% efficiency with 50% loads.

As I said. I've seen a quality 380W power supply running a FX60 + 2 x X1900XTX (OC'd) without breaking a sweat. Power consumption is a lot smaller then people think. PSU makers lie just to sell those >600W PSU's.
