These new Xeon L5320 and Xeon L5310 chips run at 1.86GHz and 1.6GHz, respectively. Both processors have a full 8MB of L2 cache (4MB per dual-core die) as well as a 1066MHz front-side bus. In essence, the chips have identical specs to Intel's 80W Xeon E5320 and Xeon E5310, but with a lower rated TDP. Intel isn't charging a huge premium for that lower power rating, though. The new Xeon L5320 is launching at $519, and the Xeon L5310 at $455. By contrast, the Xeon E5320 is $495 on Newegg right now, while the Xeon E5310 is $359.
