New Pentium Chipsets Launched 151
MojoDog writes "Today Intel has officially taken the wraps off
their new mainstream
Pentium D 820 Processor and i945 Express series chipsets.
Additionally, they also cranked up the Pentium 4 6XX sequence line-up to include
the new
Pentium 4 670 at 3.8GHz. The Pentium D 820 is Intel's new dual core
CPU clocked at 2.8GHz, which contains two Prescott cores per die but doesn't support
HyperThreading like the
Pentium Extreme Edition 840. The i945 is their new mainstream PCI
Express based chipset, one version of which has Integrated Graphics and both
supporting these new dual core CPUs. Additionally, Intel took their Pentium 4
6XX sequence processor, based on the Prescott 2M core, for a speed bump to
3.8Ghz."

Though in this case it's not so much a bad egg as a mediocre one. The current Intel design is little more than a pair of cores slapped onto a single piece of silicon, with little integration between them. The AMD design leverages the advantage of having multiple cores by allowing communication directly over the on-die system request interface rather than the external front-side bus.
