No there’s no Pentium 5!
All of the currently available and upcoming Intel performance desktop processors use Pentium 4 technology. The ‘Tejas’ project which was intended to produce the ‘Pentium 5’ was discontinued and abandoned earlier in 2004, and just lately Intel has also abandoned plans to produce a 4 GHz Pentium 4 processor as well. Intel is in a ‘bit of a pickle’!
The ‘Tejas’ project was not the only one discontinued by Intel, and the next couple of years might prove to be a slow period for the processor ‘Giant’ until new projects are brought to fruition.
