Before the Coffee Lake architecture, most Xeon and all desktop and mobile Core i3 and i7 supported hyper-threading while only dual-core mobile i5's supported it. Post Coffee Lake, increased core counts meant hyper-threading is not needed for Core i3, as it then replaced the i5 with four physical cores on the desktop platform. Core i7, on the ...

Computer processing efficiency, measured as the power needed per million instructions per second (watts per MIPS) Instructions per second (IPS) is a measure of a computer's processor speed.
Ideally, a dual core processor would be nearly twice as powerful as a single core processor. In practice, the performance gain is far smaller, only about 50%, due to imperfect software algorithms and implementation. [94] Increasing the number of cores in a processor (i.e. dual-core, quad-core, etc.) increases the workload that can be handled.

The Time Stamp Counter was once a high-resolution, low-overhead way for a program to get CPU timing information. With the advent of multi-core/hyper-threaded CPUs, systems with multiple CPUs, and hibernating operating systems, the TSC cannot be relied upon to provide accurate results — unless great care is taken to correct the possible flaws: rate of tick and whether all cores (processors ...
