Celeron with 2.0 GHz in the test: Does a Pentium 4 competitor overclock to 3.0 GHz?

Celeron with 2.0 GHz in the test: Does a Pentium 4 competitor overclock to 3.0 GHz?

A question of the CPU

For all friends of the no-frills theory, before we get down to the nitty-gritty, we want to take another look at the key data of the Throw opponents.

At first glance it becomes clear that the new Celeron is a real Pentium 4 apart from the 75% smaller L2 cache. However, Intel is silent about the information about the number of transistors and the DIE size. However, there are probably no deviations from the true Pentium 4, except for the fact that part of the L2 cache has been deactivated and therefore not all transistors are used.
