Intel 4th generation processors were originally released back in June 2013. Intel has now updated the chipsets with some improvements. Intel updated the lineup with 4 “Bay Trail” SoCs which are designed for users having low budget, 3 Haswell SoCs for ultrabooks and ultra-thin laptops and 4 Haswell CPUs for high performance and gaming laptops.
New SoC’s include Core i5-4278U, i5-4308U and i7-4578U, clocked at 2.6 GHz, 2.8 GHz and 3 GHz respectively. All processors are dual core mobile CPUs. All of them support Hyper-Threading and Turbo Boost technologies. Turbo Boost technology lets your processor increase its clock speed when needed. Processor will automatically boost its clock speed when a heavy task is demanded. And Hyper Threading technology lets your processor different tasks in threads. In this way a dual core processor can work in 4 threads.
In H series processors, there is a flagship Core i7-4980HQ which is clocked at 2.8 GHz and has a maximum Turbo Boost of 4 GHz. It has 4 cores and 8 threads. Other processors in category are shown below. Three of them are high performance Intel Core i7 with 4 cores and 8 threads. Here is the full list:
Intel also introduce 4 Celeron and Pentium class processors. These processors use very low power and are cheaper to use in low power notebooks. These include 3 Intel Celeron processors and a Pentium processor with 4 cores. All Celeron processors are priced at $107 while Pentium processor is priced at $161. Here is the full detailed list:
