Intel Core i5 vs. Core i7.
These two chips look similar, with the same cache, almost the same clock speed, and similar GPUs–but they have different operating TDPs and hence offer different user experiences.
## Core i7 chips carry either 6MB or 4MB of cache. Core i5 chips run the gamut here.
## Intel’s Core i7 processors are quad-core chips with Hyper-Threading enabled.
## Intel’s dual-core mobile Core i7 chips typically have higher clock speeds than their Core i5 counterparts, even at the same TDP.
