Intel's first Celeron processor based on its 32 nanometer Arrandale design should ship this spring, a leak says today. The P4500 will clock in at just 1.86GHz but should be a dual-core example and have 2MB of Level 2 cache and perform faster than an older 45nm Celeron. Both Hyperthreading and Turbo Boost will reportedly be disabled, as with the Core i3, to keep the price down and differentiate from faster Core i5 and i7 models.
