Haswell: What Intel's new processor promises for Mac users

Roman Loyola | June 13, 2013
Intel's Haswell processors are geared for better power management and graphics performance.

Apple says that the HD Graphics 5000 in the new MacBook Air is 40 percent faster than Intel HD Graphics 4000 found in the previous MacBook Air. Macworld Lab will be testing this claim as part of our benchmarks.

Overall performance
The emphasis with Haswell's microarchitecture is power management and graphics speed. While Intel says the new CPU will be faster than its Ivy Bridge predecessor, the changes to the CPU processing aren't major, and the boost may be 10 percent--a slight bump compared to, say, the boost experienced when transitioning from Sandy Bridge to Ivy Bridge processors. (Macworld Lab saw a 15 to 21 percent increase in the 2012 MacBook Air when it switched from Sandy Bridge to Ivy Bridge processors.)

Our sister publication, PCWorld, hasn't yet benchmarked the mobile Haswell processors, but it has tested the desktop Haswell CPUs, and the results seem to bear this out (at least on Windows).
