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.

nurbsenvi: Obviously nothing is guaranteed in overclocking, but yes a low power/low voltage version of CPU should overclock better than the higher power version the vast majority of the time. This low power version creates less heat and uses a lower stock voltage (which are interrelated) to achieve the same speeds. Being stable at a lower voltage for the same speeds generally means a better/more efficient CPU also. And 2 of the major things that limit your maximum overclock are heat and the maximum safe voltage you can give your CPU. So if one chip can do stock speeds at lower voltage and giving off less heat you can generally assume that these differences will remain as you continue to overclock. Basically you have more "wiggle room" at the top end with the low power versions. Which is why so many overclockers have chosen in the past to run low power mobile versions of desktop CPU's in their main setup. But, like I said nothing is guaranteed.

Yehuda: While I agree and understand the benefits undervolting can have in various scenarios (especially passively cooled silent pc's, sff setups, and HTPC's for example). It can actually be quite dangerous (even more so than overvolting) depending on the type of setup you have. A64's have been known to die running low vcore and high vdimm. The combination of a low cpu voltage and high memory voltage did not play nice with the on die memory controller and a lot of people lost their A64's very fast unfortunately. This is no longer an issue with the much lower voltage used in DDR2, however if it is to be discussed more people need to be aware of possible dangers related to certain configurations.
