Intel’s 15th Gen Arrow Lake CPUs: No Hyper-Threading or Rentable Units

Intel’s upcoming 15th Gen Arrow Lake processors are stirring up the tech world with their unique features and advancements. These processors will be the first in a long time to lack hyper-threading (SMT), a technology that has become a staple in Intel’s lineup. Additionally, they won’t feature Rentable Units, which is a surprising move for the company.

The confirmation of these changes comes from @xinoassassin1 on X, a reliable source in the tech community. According to them, the decision to drop hyper-threading in the Arrow Lake processors is a strategic move to prepare for the shift to Rentable Units in future generations. While this may disappoint some users who rely on hyper-threading for improved multitasking performance, it signals Intel’s commitment to exploring new technologies and pushing boundaries.

The 17th Gen Nove Lake processors will be the first to adopt the next-gen multi-threading technology, which is an exciting prospect for enthusiasts and professionals alike. However, it’s the 15th Gen Arrow Lake processors that will be the true successors to the popular Alder/Raptor Lake on desktop. These processors will feature the upgraded Lion Cove and Skymont cores, promising significant improvements in performance and efficiency.

One notable upgrade in the Arrow Lake processors is the “Lion Cove” P-Cores, which are expected to increase their L2 cache by 50% to 3MB per core. This enhancement, combined with the advanced 2nm-class Intel 20A process, is projected to deliver impressive single-threaded performance gains. Early estimates suggest that Arrow Lake could see a performance uplift of up to 20% compared to the Raptor Lake Refresh. The most significant improvements are expected in Floating Point and Memory-sensitive workloads, including gaming.

But it’s not just the CPU performance that’s getting a boost. The integrated graphics, known as the iGPU, will also receive a makeover in the 15th Gen Arrow Lake family. Thanks to the Xe-LPG Gen 2 graphics architecture, these processors will offer at least twice the performance of their predecessors. In benchmark tests, such as 3DMark Time Spy and Wildlife Extreme Unlimited, the Arrow Lake processors have shown improvements of 2.4x and 2.2x, respectively.

Looking ahead, Intel has plans for a refresh of the Arrow Lake family that could feature up to 40 cores (8P + 32E) on desktop platforms. The mobility segment might also see a new architecture, possibly named Panther Lake. Intel has been prioritizing the mobility market with new process nodes and core architectures, as seen with previous releases like Ice Lake, Tiger Lake, and Meteor Lake. This approach not only reduces the load on new nodes but also ensures a consistent roadmap for future innovations.

In conclusion, Intel’s 15th Gen Arrow Lake CPUs are shaping up to be an exciting addition to the company’s processor lineup. With the absence of hyper-threading and Rentable Units, these processors represent a significant shift in Intel’s strategy. However, the upgraded Lion Cove and Skymont cores, along with improvements in cache size and graphics performance, promise to deliver impressive gains in single-threaded performance and overall user experience. As we eagerly await their release, it’s clear that Intel is determined to stay at the forefront of CPU technology and continue pushing boundaries for the benefit of consumers and professionals alike.

Technology Explained


CPU: The Central Processing Unit (CPU) is the brain of a computer, responsible for executing instructions and performing calculations. It is the most important component of a computer system, as it is responsible for controlling all other components. CPUs are used in a wide range of applications, from desktop computers to mobile devices, gaming consoles, and even supercomputers. CPUs are used to process data, execute instructions, and control the flow of information within a computer system. They are also used to control the input and output of data, as well as to store and retrieve data from memory. CPUs are essential for the functioning of any computer system, and their applications in the computer industry are vast.


iGPU: An integrated Graphics Processing Unit (iGPU) is a component built into a computer's central processing unit (CPU) or system-on-chip (SoC) that handles graphical tasks. Unlike dedicated graphics cards, which are separate components, an iGPU shares system resources with the CPU, allowing for basic graphics capabilities without the need for an additional card. While typically less powerful than dedicated GPUs, iGPUs are energy-efficient and well-suited for everyday computing tasks


P-Cores: P-Cores (Performance Cores) are a type of processor technology developed by Intel that is designed to improve the performance of computer systems. This technology is based on the concept of multi-core processors, which are processors that contain multiple cores or processing units. P-Cores are designed to increase the speed and efficiency of computer systems by allowing multiple cores to work together in parallel. This technology is used in a variety of applications, including gaming, video editing, and data analysis. P-Cores are also used in servers and other high-performance computing systems. The technology is also used in mobile devices, such as smartphones and tablets, to improve battery life and performance. P-Cores are an important part of the computer industry, as they allow for faster and more efficient computing.


SMT: Simultaneous multithreading (SMT) is a technology that allows a CPU core to process two tasks (threads) simultaneously. It is crucial to the swift operation of modern-day CPUs. SMT is AMD’s brand of multithreading, while Hyperthreading is Intel’s
