That machine earned a Speedmark 9 score of 350. The strongest-performing Mac we’ve tested thus far is a custom-built Late 2013 Mac Pro with an eight-core 3.0GHz Xeon E5 processor, 512GB of flash storage, 32GB of DDR3 memory, and AMD FirePro D700 dual graphics with 6GB of dedicated video memory on each video card. Our baseline system, which is assigned a score of 100 and whose performance serves as the reference value that we compare the individual test performance of every other system to, is a 2011 13-inch MacBook Air laptop with a dual-core 1.7GHz Core i5 processor, a 256GB solid-state drive, 4GB of DDR3 memory and integrated Intel HD 3000 graphics. This single result compiles the performance scores from the 14 individual tests and boils them down to a single number. To find out which system performs best overall, we use a Speedmark 9 score.
