Intel dual desktop core chips to be called x20, x30, x40

THE LONG AWAITED Intel roadmaps which specify details of its shift from the Pentium 4 to dual core processors have been shown to its OEM customers.
And it appears that when the first "Smithfield" core processors are launched in the third quarter of next year, they will be called the x20, the x30 and the x40. An x20 is a twin 1MB L2 cache processor supporting EM64T extensions and the "execute disable" bit.
