Intels desktop Celeron D chips are to be the latest processors to get the chip giants NetBurst core update, The Register has learned. According to Intel documentation, Celeron model numbers 326, 331, 336, 341, 346 and 351 will switch from todays E-0 core to the updated G-1 core on 2 December.
The G-1 core stepping will not only be compliant with European Reduction of Hazardous Substances (RoHS) regulations, courtesy of a "lead-free second level interconnect", but add two new instructions to Intels AMD64-like EM64T 64-bit addressing system. Intel is adding the LAHF and SAHF AMD64 instructions to its own 64-bit instruction set architecture. It has been alleged that they were missing from the original EM64T specification because the AMD documents used by Intels engineers pre-dated AMDs addition of the two mnemonics.
