TechPowerUp spotted a weird Intel Core i7-8670 processor in the database of the GFXBench benchmark. This chip breaks Intel's typical naming convention, and seems to be a six-core chip with twelve threads. It has a 3.1GHz base clock and has the Intel UHD 630 integrated graphics.
The processor's name breaks Intel's naming conventions of reserving the 87xx model number for Core i7 MSDT (mainstream desktop) SKUs, and 86xx for Core i5 SKUs, based on the 8th generation "Coffee Lake" silicon.
Perhaps this is a cheaper 12-threaded part to heat up competition with AMD.
