The Power Macintosh was formally introduced at the Lincoln Center for the Performing Arts in Manhattan on March 14. Pre-orders for the new Power Macintosh models were brisk, with an announced 150,000 machines already having been sold by that date. MacWorld's review of the 6100/60 noted that "Not only has Apple finally regained the performance lead it lost about eight years ago when PCs appeared using Intel's 80386 CPU, but it has pushed far ahead." Performance of 680x0 software is slower due to the emulation layer, but MacWorld's benchmarks showed noticeably faster CPU, disk, video and floating point performance than the Quadra 610 it replaced. By January 1995, Apple had sold 1 million Power Macintosh systems.
