Does Macos Catalina Improve Performance
| Processor Speed: | 2.5 GHz | Processor Type: | Core i7 (I7-4870HQ) |
| Details: | This model is powered by a 22 nm, 64-bit 'Fourth Generation' Intel Mobile Core i7 'Haswell/Crystalwell' (I7-4870HQ) processor which includes four independent processor 'cores' on a single silicon chip. Each core has a dedicated 256k level 2 cache, shares 6 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 3.7 GHz for this model) -- and 'Hyper Threading' -- which allows the system to recognize eight total 'cores' or 'threads' (four real and four virtual).
