Intel’s Meteor Lake CPUs Could Face Latency Issues, Impacting Gaming Performance

Summary: Upcoming Intel Meteor Lake processors generating buzz, but recent leaks suggest potential memory latency challenges and caution should be exercised until official release and independent tests provide a clearer picture of performance.

  • First AI-ready chips from Intel
  • Modular design with heterogeneous core mixture
  • Design choice reduces chances of latency penalties


Intel’s upcoming Meteor Lake processors have been generating quite a buzz in the tech world. Marketed as the first AI-ready chips from Intel, these CPUs are also the company’s first foray into chiplet-based (modular) designs, featuring a heterogeneous core mixture and varying process technology. However, recent leaks suggest that these processors may face some challenges when it comes to memory latency, potentially impacting gaming performance.

According to leaked information, the Intel Core Ultra 9 185H, part of the Meteor Lake lineup, recorded an L3 cache latency of 49 ms. This is nearly three times higher than the existing Raptor Lake processors. Additionally, the L3 read/write and copy speeds were only a third of the expected values, dropping to 568/s|303GB/s and 372GB/s, respectively. These figures might represent the memory bandwidth/latency of the LP cores on the SoC die, but it’s important to note that AIDA64, a popular system diagnostics and benchmarking tool, has released a beta patch to address reported figures on hybrid core processors.

While these leaks certainly raise concerns about potential latency issues with Intel’s Meteor Lake CPUs, it’s crucial to approach them with caution. Without official confirmation or third-party benchmarks, it’s impossible to draw a definitive conclusion at this point. We’ll have to wait for the official launch and independent tests to get a clearer picture of the performance of these chips.

One aspect worth highlighting is that unlike AMD’s chiplet CPUs, where different cores are spread across multiple dies, all of Intel’s P and E cores in the Meteor Lake processors reside on the same die. This design choice reduces the chances of experiencing latency penalties, except when considering the LP cores on the SoC die. This could potentially be a factor contributing to the reported memory latency issues.

As enthusiasts eagerly await more information and concrete performance data on Intel’s Meteor Lake CPUs, it’s important to remember that leaks and rumors should always be taken with a grain of salt. While they provide an intriguing glimpse into what’s to come, they don’t always reflect the final product. So, let’s reserve our judgment until the official release and comprehensive reviews shed light on the true capabilities of these AI-ready chips.

Technology Explained


chiplet: Chiplets are a new type of technology that is revolutionizing the computer industry. They are small, modular components that can be used to build powerful computing systems. Chiplets are designed to be used in combination with other components, such as processors, memory, and storage, to create a complete system. This allows for more efficient and cost-effective production of computers, as well as more powerful and versatile systems. Chiplets can be used to create powerful gaming PCs, high-end workstations, and even supercomputers. They are also being used in the development of artificial intelligence and machine learning applications. Chiplets are an exciting new technology that is changing the way we build and use computers.


L3 cache: L3 cache is a type of computer memory that is used to store frequently used data and instructions. It is located between the processor and main memory, and is used to reduce the amount of time it takes for the processor to access data from main memory. This helps to improve the overall performance of the computer. In the computer industry, L3 cache is used in many applications, such as gaming, video editing, and web browsing. It can also be used to improve the performance of servers and other high-performance computing tasks. By providing faster access to data, L3 cache can help to reduce the amount of time it takes for a computer to complete a task.


latency: Technology latency is the time it takes for a computer system to respond to a request. It is an important factor in the performance of computer systems, as it affects the speed and efficiency of data processing. In the computer industry, latency is a major factor in the performance of computer networks, storage systems, and other computer systems. Low latency is essential for applications that require fast response times, such as online gaming, streaming media, and real-time data processing. High latency can cause delays in data processing, resulting in slow response times and poor performance. To reduce latency, computer systems use various techniques such as caching, load balancing, and parallel processing. By reducing latency, computer systems can provide faster response times and improved performance.


SoC: A System-on-Chip (SoC) is a highly integrated semiconductor device that encapsulates various electronic components, including processors, memory, input/output interfaces, and often specialized hardware components, all on a single chip. SoCs are designed to provide a complete computing system or subsystem within a single chip package, offering enhanced performance, power efficiency, and compactness. They are commonly used in a wide range of devices, from smartphones and tablets to embedded systems and IoT devices, streamlining hardware complexity and facilitating efficient integration of multiple functions onto a single chip.
