Intel and AMD's 2005 Plans Revealed 272
Takemedown writes "There's a good article on CTZ that talks about Intel and AMD's plans. Intel, continuing on their 18-month chipset refresh rate, will introduce their Glenwood and Lakeport chipsets for the Smithfield dual core desktop microprocessor in 2005. The chipsets will support SATA II, Matrix RAID and a higher system bus speed for the new Pentium 4 name holder.
As far as Intel's dual core strategies are concerned, they will most likely bring their dual core additions by the very end of Q2 or Q3 this year, so for those waiting for these next generation chips are better off with a due upgrade. Secondly, if you are hoping for a noticeable performance gain in regular computing tasks are in for a disappointment. Dual core microprocessors are for those who like to do multitasking or work on multithreaded applications. For example, if you are gaming and burning a DVD at the same time, dual core chips will come in handy and will definitely give a smooth computing experience."

This can be achieved on a commodity single-core processor using pure software techniques. The technique is known as Error-Detection through Duplicated Instructions (EDDI), and is implemented as a compilation step between assmbly code generation and object file generation. Stanford has done a bunch of work on this at their Center for Reliable Computing. I don't have any links readily available, but I'm sure that if you Google on EDDI and the ARGOS project you'll find some good info.
Note that IIRC experiments at Stanford showed that when using EDDI on a modern super-scalar processor the EDDI instructions can take advantage of unused portions of the pipeline, resulting in a significant reduction in overhead. You might still experience a slight performance hit, but on the other hand you don't need to add a whole new processor or core.

Mostly, though, the advantage will be social -- if a large fraction of systems have multiple processors, as they will soon, then more and more applications will be written to take advantage of them.
