ThinkPad T470 is powered by Intel core i5-7200U CPU. This is part of the Kaby Lake architecture (Intel’s 7th generation). This processor is still very capable to handle most of the daily tasks.  

Clock Speed and Turbo Boost: The i5-7200U operates at a base frequency of 2.5Ghz, which is significantly high when compared to modern laptops whose base frequency keeps on reducing to increase the battery life. With Turbo boost technology, the processing speed can increase to 3.1Ghz when the workload requires it. 

Cores vs. Logical Processors: This processor has a 2-core, 4 logical processor architecture. For tasks, such as Web development, office administration, and virtual meeting, it gets the work done very smoothly.
   •Physical Cores: The two physical cores handle the heavy lifting.
   •Hyper-Threading: Intel’s hyper-threading technology is configured to allow 2 tasks                                simultaneously. This gives you 4 logical processor, and a very smooth performance when multi-        tasking. While working, it allows Windows update, Antivirus scan to run alongside primary                  applications. 

The Cache Hierarchy: The Speed of Information: The T470’s cache configuration is optimised for low-latency performance:
   •L1 Cache (128 KB): It is the fastest, sitting right on the core to handle immediate instructions.
   •L2 Cache (512 KB): Acts as a middle-ground buffer.
   •L3 Cache (3.0 MB): Known as the Smart Cache, this is shared across all cores, ensuring that data-      heavy applications have a “reserve tank” of memory.
