Macworld notes that Intel is officially announcing the availability of more power-efficient quad-core Xeon processors to be available today.
The new Xeon L5320 and L5310 processors consume only 12.5 watts of electricity per core, using 35-60% less power than the existing quad-core Xeons.
The L5320 operates at 1.86 GHz and the L5310 at 1.60 GHz. They both feature 8M bytes of on-die cache for faster memory data communication. In quantities of 1,000 units, the L5320 is priced at US$519 and the L5310 at $455.
No word on whether or not Apple is planning on using the newest Quad-core processors in upcoming Macs, despite persistent rumors of Apple introducing a 8-Core Mac Pro. These new processors, however, feature a slower clock speed (1.60GHz, 1.86GHz) than the existing less power-efficient (2.66GHz) Clovertown Quad-core processors.
For readers interested in the top end of performance, Intel revealed last week that later this year, they will be releasing a higher end 3.0GHz version of its Quad-core Xeon for customers who aren't concerned with power consumption.
The current 2.66GHz Quad-cores or these upcoming high end chips appear to be the most likely candidates for future 8-Core Mac Pro models, as power consumption is not a major consideration for Apple's high end desktop machines.
