Consumers who think six or 8 cores are many in a processor probably never had a reason to look up parallel chips and digital signal processors (DSP), but French company Kalray may change that.
What they've announced is a DSP chip which, thanks to its 256 individual cores (yes, that many) can perform 500 billion operations per second (200 GigaFLOPS). One would think that something like that would require a lot of power, but that does not apply here. The processor actually makes do with 4W, less than the average mobile chip. For comparison, a mighty Tesla series GPU has a performance of 1,030 to 2,280 (single-precision). A factor of 5-10 isn't bad at all really. Granted, being a digital signal processor, Kalray's...
