Intel is planning to release quad-core Kentsfield based Xeon 3000 seriesprocessors. The new Xeon X3220 and X3210 processors will be identical to the recently named Intel Core 2 Quadro processors and share the same Kentsfield core.

There will be no architectural or socket differences between desktop Core 2 Quadro and Xeon X3000 series processors, with the exception of product placement and marketing. The new Xeon X3220 and X3210 processors will arrive clocked at 2.4 and 2.13 GHz with a 1066 MHz front-side bus respectively. Both Kentsfield Xeon X3000 processors will feature 8MB of L2 cache. Expect the Intel Xeon X3220 and X3210 to arrive in Q1’07 for $851 and $690 in 1,000-unit lots.

Before Intel releases its Kentsfield based Xeons it will release Clovertown Xeon DP processors. The new Clovertown Xeon DP processors are quad-core and multi-processor enabled. With a compatible LGA771 motherboard users can install two Clovertown processors in a system for eight-core computing. The new Xeons will arrive in X5355, E5345, E5320 and E5310 models clocked at 2.66, 2.33, 1.86 and 1.60 GHz respectively. Intel Xeon DP models X5355 and E5345 will have a 1,333 MHz front-side bus while the Xeon DP E5320 and E5310 have a slightly slower 1,066 MHz front-side bus. All Clovertown Xeon processors will have 8MB of L2 cache. Pricing for Intel Clovertown Xeon DP processors will be $1172, $851, $690 and $455 for models X5355, E5345, E5320 and E5310 in 1,000-unit lots respectively. Availability is expected later this quarter.

Lastly on the Intel Xeon roadmap is one new Tulsa Xeon MP processor. The new dual-core Xeon MP 7150N will be clocked at 3.5 GHz with a 667 MHz front-side bus. This particular model will have 2MB of L2 cache and 16MB of L3 cache. Pricing for the new Xeon MP 7150N will be $2,622 in 1,000 unit lots. Availability is expected in Q1’07.
