AnandTech offers some commentary about the three new Ice Lake CPUs that appeared in the Intel ARK database. The Core i7-1060NG7, the Core i5-1030NG7, and the Core i3-1000NG4 are new 10nm parts with a slightly higher base clock and a slightly higher TDP than previous parts.
The site believes these are the processors that are used by Apple's new MacBook Air laptops. When asked about these chips, an Intel representative stated that the "N" denotes a customer-specific version of those SKUs:
When we approached Intel asking what these CPUs were, and the official line is:
“The ‘N’ notes a slightly differentiated, customer-specific version of those SKUs. Those slight differences require a signifier for our internal SKU management and ordering systems. The N is not a new subfamily or directly connected to a specific set of features, for example.”
This goes in line with what we stated above about customer-specific binning. Apple will no doubt be ordering a few million of these CPUs, so Intel is prepared to add an extra binning step just for the business.
