Sander Sassen van HardwareCentral heeft een artikel in elkaar gezet over de Intel Willamette, die in oktober gereleased wordt en aan het einde van dit jaar kloksnelheden van 1.5GHz moet trekken. In het artikel o.a. uitleg over SSE2, de 20-stage pipeline en Trace Cache. Hieronder een hap uit de conclusie:
Although Intel’s Willamette will probably be the first CPU to break the 1.5 GHz mark, due to its long pipeline and long latencies, the actual performance of the Willamette in comparison to the Pentium III Coppermine may not be all that spectacular if we compare them running at similar clockspeed.However if Intel can give software developers enough incentive to start using SSE2 for doing floating point calculations, the Willamette will offer a performance level which is unparalleled by any current or upcoming CPU. It takes time to build up software support and re-write applications, but Intel has proven to be very good at supporting developers in the past, thus they could very well pull it off.
Overall, Intel has implemented quite some inventive solutions in the Willamette CPU to be able to reach clockspeeds in excess of 1.5 GHz. The new SSE2 instructions, the long pipeline, the trace cache and the improved branch prediction algorithms all attribute to a CPU that could promise to be a wolf in sheep’s clothing. We at HardwareCentral are keeping our eyes open for future developments.
