Each core has a dedicated 256k level 2 cache, shares 4 MB of level 3 cache, and has an integrated memory controller (dual channel).

This system also supports 'Turbo Boost 2.0' - which 'automatically increases the speed of the active cores' to improve performance when needed (up to 3.6 GHz for this model) - and 'Hyper Threading' - which allows the system to recognize four total 'cores' or 'threads' (two real and two virtual).ДЄ MacBook Pro (2017) with 2.5GHz dual-core 7th-generation Intel Core i7 processorДetails: This model is powered by a 14 nm, 64-bit 'Seventh Generation' Intel Mobile Core i7 'Kaby Lake' (I7-7660U) processor which includes two independent processor 'cores' on a single silicon chip with 64 MB of eDRAM embedded on the processor die.

Your current Macwith 2.9 GHz Intel Core i7Дetails: This model is powered by a 22 nm, 64-bit Intel Mobile Core i7 'Ivy Bridge' (I7-3520M) processor which includes two independent processor 'cores' on a single silicon chip. What you should do is compare the processors. Not only does the newer MacBook processor have more cores (in one case), they are both a newer generation processor.
