Intel's latest roadmap reveals three new Penryn based Xeon models with a higher front-side bus speed - 1600MHz. The three new processors are available in dual-core and quad-core models. Quad-core Xeon E5472 and E5462 are the first quad-core models to receive the 1600MHz FSB treatment. The Xeon E5472 features a 3.0GHz clock speed while the E5462 is clocked at 2.8GHz. Both CPUs feature 80-watt TDP. Intel plans to release these 1600 MHz front-side bus processors in Q4 2007 with the rest of the Penryn family. Pricing for the quad Xeons starts at $797 for the E5462 and $958 for the E5472, per processor, in 1,000 unit quantities. The third and only dual-core 1600MHz FSB processor is E5272. The Xeon E5272 features a 3.4GHz clock speed and is priced at $1,172. Intel has also pulled in the launch of E5272 to Q4 2007, with the quad-core processors.
