Today Primate Labs reported about the Geekbench results for the new 21.5-inch iMac showing fairly strong increase in performance compared to the previous generation of computers. The report focuses on the 21,5''iMacs, as the 27''models will not be available for 2-3 more weeks. The new iMacs scored about 25% higher than its counterpart launched in 2011 and even outperformed the high-end 27-inch iMac from 2011 by about 10%.
