iCOMP for Intel Comparative Microprocessor Performance was an index published by Intel used to measure the relative performance of its microprocessors.. Intel was motivated to create the iCOMP rating by research which showed that many computer buyers assumed that the clock speed – the “MHz” rating – was indicative of performance, regardless of the processor type. iCOMP ratings based on ...
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 ...

Itanium processor featuring an all-new microarchitecture. [26] 8 cores, decoupling in pipeline and in multithreading. 12-wide issue with partial out-of-order execution. [27] Kittson the last Itanium. It has the same microarchitecture as Poulson, but slightly higher clock speed for the top two models.

Further, a "cumulative clock rate" measure is sometimes assumed by taking the total cores and multiplying by the total clock rate (e.g. a dual-core 2.8 GHz processor running at a cumulative 5.6 GHz). There are many other factors to consider when comparing the performance of CPUs, like the width of the CPU's data bus , the latency of the memory ...
