Intel's 3.8GHz Pentium 4 570J has yet to be added to the chip maker's price list, but it's expected to be launched today and indeed has already started appearing in the Japanese chip stores.

Sony has even launched a Vaio Type R desktop PC based on the new processor.

With Intel's decision to drop the 4GHz P4, the 570J - the 'J' indicates support for the no-execute bit - is likely to be the highest clocked 'Prescott'-based P4 we'll see, with future incarnations of the chip boosting performance through bigger caches and faster frontside bus clocks.

The new chip uses an 800MHz FSB and offers 1MB of L2 cache, but Intel is expected to announce the P4 6xx series early next year, which include 2MB of on-die L2 cache and 64-bit addressing through EM64T support. Launched at 3-3.6GHz, a 3.8GHz P4 670 is set to ship in Q2 2005. That's it before the dual-core 'Smithfield' arrives, in Q3.

Although not yet confirmed, it's likely the 570J will be based on the E-0 P4 core stepping. Lesser-clocked P4s are due to appear in E-0 form in a week's time, on 22 November. ®
