i7 with 4 cores. "Great" refresh. The model number cannot get more confusing. I feel Intel needs to clean this mess up soon. We used to have i3, 5, 7 and 9 to clearly demarcate the different tier of processors where the higher the number, the more cores/ more power they become. Now they have a few i7 models, some with 4, some with 8 cores. Then they have the G7(suffix) to indicate the iGPU config, which can differ in specs (different number of EUs) as well. I really feel Intel is running in every direction in panic.
Intel probably created these skus for certain OEMs for differentiation with their competition. Microsoft for example in their surface lineup never used the mainstream U-series skus - they used the i7 6600U, 7600U, 8650U instead of, respectively, the mainstream i7 6500U, 7500U, 8550U.
