"D" stands for dual, as in dual core processor. it's amazing how much tech goes into the lower "budget" alternative!
Intel recently completed the 64-bit transition of its entire line of microprocessors from the desktop to the server with the release of its new Celeron D processors. Equipped with 256 KB of L2 cache, the EMT64-enabled Celeron D processors are available in clock speeds up to 3.2GHz. Toggling with a bus speed of 533MHz, the chips are manufactured using Intel's 90 nm process technology, available in LGA775 packaging. The low-cost chips also support the execute disable bit (a.k.a. XD, or NX--see our previous coverage), providing additional security capability for operating systems that support the feature. While Celeron D chips have typically been aimed at computers costing less than US$750, I beg to hasten the day when I can grab a few gigabytes of memory within the "Celeron budget." Nice to know the support is there.
