The Core Duo uses “2” instead, signifying its two processing units. As a dual-core CPU, the Core Duo has twice the amount of processing power as the Core Solo. Speed and Motherboard.
processor Intel core 2 duo E7400 2.80 GH; Ram 2 GB Disk 500 GB. I am already using Ubuntu 19 in my laptop .So I want to try something new , lite and faster os . I will remove windows completely and install Linux. Suggest OS that works fast in this configuration and does not freeze up. This cpu better at multitasking and single threaded application than the core 2 duo. How is this possible you may ask? Well with intel speed boost technology, that cpu can be a 1.6-1.7 GHz quad core/8 thread cpu or it can be a 2.8 GHz single core/ dual thread cpu. The turbo boost mode and speed is: 4 and 3 cores @ 1.7 GHz 2 cores @ 2.4 GHz yYEZ0.
