Il futuro dei 64bit

Processore Intel Itanium, composto da 25 milioni di transistor. Si notino i due chip della cache L3, esterni al core della cpu
L'analisi passa in rassegna quelli che saranno i prossimi processori Intel per sistemi workstation e server, a partire dalla cpu Itanium 2 di prossima introduzione e dalla cpu Prescott, evoluzione a 0.09 micron del processore Pentium 4.
L'estratto seguente riporta alcune informazioni su Prescott:
Prescott is Intel's next-generation Pentium 4 processor line, which will have close to 100 million transistors and which will be produced on a 90-nanometer process. The high-end desktop chip (still 478 pin) has been rumored to include "Yamhill" technology, a sort of "Intel x86-64."
Our sources confirmed that Prescott does indeed have a lot more cache on board - a logical evolution after Northwood - most likely a larger 1 MB L2 cache. We also received some confirmation that Prescott has quite a few architectural improvements, but no indication of x86-64 support so far. Apparently, Intel has studied x86-64, but canceled the project. It is still possible that the x86-64 extensions are in the chip, but not activated.
