Apple's dual-core A6X ARM-based SoC runs at 1.4GHz with 1 GB. The new chip includes four PowerVP SGX 554MP4 GPUs clocked at 300MHz plus twice the video memory. While Apple's new part might be faster than its old one, Intel's Core i5 still cleans its clock. In the absence of review units, we took to the Web and found Intel running rings around Apple. We even found one using Geekbench, which put i5's floating point performance and overall score at more than four times that of A6X, which would put it among the Test Center's top 10 fastest laptops.
Surface and iPad are available with 64 GB or 128 GB of storage, but Windows 8 Pro eats into a significant amount of device storage. Still, Surface is the more powerful platform by far.
