According to a historic scientific research in the new edition of Wisden Cricketers' Almanack Australia, all-rounder Kapil Dev was second in list while the Delhi-based opener is the fifth fastest in the world.
The full list - the Hurricane Hundred - is published in the 2004-05 edition of Wisden Australia, which will hit the stands on November 3.
It is the first serious undertaking ever attempted to calculate the batting strike rates of every Test cricketer since 1877, a website reported on Thursday.
Gilchrist comfortably tops the chart with a strike rate of 81.9 runs per 100 balls.
"It is fair to say that Gilchrist, taking both batting average and scoring speed into account, is the most dynamic batsman the game has ever seen," says Charles Davis, the Melbourne-based cricket scientist who conducted the research.
"One advantage he has, as with Viv Richards, is that he plays in a supremely dominant side. But even when he is exposed to predicaments demanding fierce resistance, his response is invariably aggressive."
