The next generation of Celeron-branded microprocessors was based on Pentium 4 Northwood core. These Celerons were produced on 0.13 micron technology, and had almost the same microarchitecture as Pentium 4 Northwood microprocessors with a few exceptions. Even though the size of L2 cache was doubled on Pentium 4 Northwood processors, Northwood Celerons had the same 128 KB L2 cache as their predecessors - Willamette Celeron. Front Side Bus frequency of Celeron processors was also unchanged. Celeron microprocessors didn't include Hyper-Threading technology that was present on all Pentium 4 Northwood CPUs with 800 MHz FSB. On a plus side, the Northwood Celerons had lower core voltage than their Willamette processors, as a result Northwood processors ran cooler. The Celeron CPUs were packaged in 478-pin FC-PGA2 package with integrated heatsink, and required socket 478 motherboards.
Celeron (200 Series)
Celeron (Conroe-L)
Celeron 400 series family was the first family of low-cost desktop CPUs based on Core micro-architecture. The 400 series processors include basic features of the Core microarchitecture - 64-bit processing, Execute Disable bit, enhanced branch prediction, support for SSE3 and Supplemental SSE3, quad-pumped Front-side Bus, and others. As usual for all budget processors, these Celerons do not include as many features, or have inferior features as compared to desktop high-performance CPUs. The Celeron 400 series include only single CPU core, small 512 KB level 2 cache, and they do not have Enhanced SpeedStep technology.
Mobile Celeron (Mendocino)
Intel Mobile Celeron 433 - KC80524KX433128Mobile Celeron microprocessors with Mendocino core share many features with desktop Mendocino CPUs. All Mendocino Celerons are based on P6 micro-architecture, have 32 KB level 1 cache, integrate 128 KB level 2 cache running at the CPU speed, and, like almost all others P6 CPUs, support MMX instructions. Mobile Celerons have much lower power consumption than desktop Mendocino processors partly due to lower core voltage (1.6 Volt as opposed to 2 Volt for desktop processors), and partly due to two new power-saving modes - Quick Start and Deep Sleep. The Mobile Mendocino CPUs are packaged into 615-pin micro-PGA or 615-ball BGA packages - these packages are much smaller than 370-pin PPGA package of desktop microprocessors.
