The good boys at Anandtech take the freshly announced Celeron budget CPU on a test ride. The new Celeron core is based on a 128KB L2 version of the original Willamette core that the Pentium 4 debuted with in November of 2000. Unlike previous-generation Celerons, the Willamette-128 core is no different architecturally than the Pentium 4's old Willamette core. The cache organization and mapping algorithms are still the same, the only difference is that the Celeron core is only outfitted with a 128KB L2 cache instead of the 256KB cache present on the original Pentium 4.
