The Intel Core Ultra CPUs

April 19, 2025 by Rob Last

Intel\’s latest CPU lineup showcases their \”15th generation” processors, known as \”Arrow Lake.\” These CPUs prioritize power efficiency and enhanced performance. Intel has introduced a new naming system called \”Core Ultra,\” which is intended to “simplify choices and highlight advancements”.

The \”Hybrid Core Architecture\” merges Performance-cores (P-cores) and Efficient-cores (E-cores) to achieve optimal performance and power efficiency. Most models come with Intel Xe-LPG graphics, “. . . making them suitable for everyday tasks and light gaming.”

So, the familiar “i Series” processors seem to have gone the way of 486 SX and the Pentium 4. But, what about hyperthreading? Well, it seems hyperthreading technology is still a feature in Intel\’s latest generation processors.  Hyperthreading is typically enabled on the Performance cores, allowing them to handle more tasks concurrently.

Intel claims their 15th generation processors have gained popularity in the computing world due to their focus on power efficiency and performance improvements. The new naming system, \”Core Ultra,\” is part of this lineup.

Here are some examples of popular Intel 15th gen CPUs:

  1. Intel Core Ultra 9 285K: This flagship model boasts a 24-core CPU design with eight \”Lion Cove\” performance cores and 16 \”Skymont\” efficiency cores. It has a maximum boost clock of 5.7GHz and “. . . is renowned for its impressive power efficiency and thermal gains.”
  2. Intel Core Ultra 7 265K: Featuring a hybrid core design with eight performance cores and 12 efficiency cores, this model offers a boost clock of 5.5GHz and is optimized for performance and power efficiency.
  3. Intel Core Ultra 5 245K: This processor combines six performance cores and eight efficiency cores, with a boost clock of 5.2GHz, making it suitable for various desktop computing needs.

Intel states that these CPUs are designed to handle demanding tasks while minimizing power consumption, “. . . making them popular choices for both everyday computing and gaming.”

What happened to the i3?

Regarding the Intel i3 series: This series has undergone changes over the years. Once a popular entry-level processor for basic computing tasks, Intel discontinued the series in 2020 to make way for newer, more powerful processors like the Core i5 and Core i7. They state that “The decision was driven by the need to provide better performance and advanced features for users, as the i3 processors were primarily designed for basic tasks.” So, this shift allowed Intel to focus on processors that cater to a wider range of computing needs, from everyday use to more demanding applications.
