We already published the basic consumer qualities of single core processor celeron of 4xx (Conroe- L). The announcement of this processors family will take place in the beginning of June, already after April prices reduction for processors series core 2 Duo.
Until now we did not have a clear idea about on which stepping will be based core Conroe- L. To us there was known only CPUID value , which corresponds to the sequence ( 00010661h ).
As in case of stepping B2 core conroe, signal about the passage of Intel processors on new stepping arrived from mobile segment in the form of special notice (33 KB). Intel company officially reported that single core mobile processors celeron M 520 (1.6 GHz) with 1 mb cache in the second level will be transferred from stepping B2 on new stepping A. in the revision log, was noted about the reduction in area core. IN allendale crystal , the second core was simply disconnected , and part cache in the second level was disabled.
The processors Merom- L stepping A will start to be proceed to Intel partners in the type of engineering models in first June this year, in sale they will appear after sixth July. Most likely, desktop processors Conroe- L on stepping A will appear during June. aSRock Company in the end of March , already updated the BIOS of its desktop motherboards LGA 775, after preparing them for the support of processors conroe stepping A1. For sure we deal here with the single core processors Conroe- L, which will give life to the family celeron 4xx.
