Cleric xtx Posted February 23, 2005 Report Share Posted February 23, 2005 (edited) On Sunday Intel officially launched five new processors, the Pentium 4 600 series (which includes the 630, 640, 650 and 660 processors) and the Pentium 4 XE at 3.73 GHz. All of Intel's new processors include support for eXecute Disable (XD), AMD's x86-64 (by way of EM64T), Enhanced Intel Speedstep Technology (EIST) and 2MB of L2 cache. All are based on the Prescott 2M core. XD is a technology that helps prevent buffer overflow attacks in processors and is also supported by AMD64 processors (called NX), the Pentium 4J, Celeron J and the Itanium 2. EM64T is what Intel calls their implementation of AMD’s x86-64, and EIST is a means for changing the processors speed in order to make it run cooler. Pricing is expected to be $999 (USD) for the XE, $605 for the 660, $401 for the 650, $273 for the 640 and the 630 at $224. Personally, I don't see why they can't just give them all (or at least most) the same name. Edited February 23, 2005 by Cleric xtx Link to comment Share on other sites More sharing options...
