I’m sure you’ve all seen it by now, maybe you haven’t, but Intel has shelved plans for the release of a 4GHz P4. The chip was due out by the beginning of next year, but they’re focusing on cache improvements instead. The vanilla P4’s will now carry 2MB of cache, like their Xeon bretheren…. what’ll keep people buying Xeons now?
"Instead, Intel will boost performance on its chips by increasing the size of the cache, a pool of memory located on the processor for rapid data access. Current mainstream Pentium 4s now have 1MB cache. In the future, these chips will have 2MB of cache, like Intel’s Xeon server chips and the ‘Extreme Edition’ Pentium 4s designed for gaming PCs."
