Intel Celeron (Conroe-L) processors
Introduction: June 2007
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 Conroe-L core
The Conroe-L Celeron was a single-core processor built on the Intel Core microarchitecture and was thus clocked much lower than the Cedar Mill Celerons, but still outperforms them. It was based on the 65 nm Conroe-L core, and uses a 400-series model number sequence. The FSB was increased to 800MHz from 533MHz in this generation, and the TDP was decreased from 65W to 35W. As is traditional with Celerons, it does not have Intel VT-x instruction support or SpeedStep. All Conroe-L models were single-core processors for the value segment of the market, much like the AMD K8-based Sempron. The product line was launched on June 5, 2007.
On October 21, 2007, Intel presented a new processor for its Intel Essential Series. The full name of the processor was a Celeron 220 and was soldered on the D201GLY2 motherboard. With 1.2GHz and a 512KB second level cache it had a TDP of 19 watt and can be cooled passively. The Celeron 220 was the successor of the Celeron 215 which was based on a Yonah core and used on the D201GLY motherboard. This processor was exclusively used on the mini-ITX boards targeted to the sub-value market segment.
