Intel Celeron D (Cedar Mill-512) processors
Introduction: May 2006
The Celeron brand refered to a range of Intel's x86 CPUs for budget/value personal computers. Considered Intel's "economic" processor, the Celeron branded processors had complemented Intel's higher-performance (and more expensive) brands. Intel had given the brand the motto, "delivering great quality at an exceptional value." Celeron processors was able to run all IA-32 computer programs, but their performance was somewhat lower when compared to similar, but higher priced, Intel CPU brands. For example, the Celeron brand often had less cache memory, or had advanced features purposely disabled. These missing features had a variable impact on performance. In some cases, the effect was significant and in other cases the differences were relatively minor. Many of the Celeron designs had achieved a very high "bang to the buck," while at other times, the performance difference had been noticeable. For example, some intense application software, such as cutting edge PC games, programs for video compression, video editing, or solid modeling (CAD, engineering analysis, computer graphics and animation, rapid prototyping, medical testing, product visualization, and visualization of scientific research), etc. may not performed as well on the Celeron family. This had been the primary justification for the higher cost of other Intel CPU brands vs. the Celeron.
The Cedar Mill-512 core
Based on the Cedar Mill Pentium 4 core, this version of the Celeron D was launched May 28, 2006,and continued the 3xx naming scheme with the Celeron D 347 (3.06GHz), 352 (3.2GHz), 356 (3.33GHz), 360 (3.46GHz), and 365 (3.6GHz). The Cedar Mill Celeron D was largely the same as the Prescott-256, except with double the L2 cache (512KB) and based on a 65 nm manufacturing process. The Cedar Mill-512 Celeron D was LGA 775 exclusive. The main benefits of the Cedar Mill Celerons over the Prescott Celerons were the slightly increased performance due to the larger L2 cache, higher clock speeds, and less heat dissipation, with several models having a TDP lowered to 65 watts from Prescott's lowest offering of 73W.
In Intel's "Family/Model/Stepping" scheme, Cedar Mill Celeron Ds and Pentium 4s were family 15, model 6, and their Intel product code was 80552.
