Intel’s 1st Gen Core Ultra CPUs Lag Behind AMD’s Ryzen 7000 Chips in Speed and Power Efficiency

Intel has recently released its 1st Gen Core Ultra processors, which mark the debut of the 4nm-class Intel 4 process node. These new Meteor Lake chips are the first from Intel to utilize a modular architecture with the iGPU/SoC dies fabricated on TSMC’s 4nm/6nm nodes. While Intel’s official benchmarks may have painted a picture of modest improvement over their previous Raptor Lake chips, unbiased third-party reviews tell a different story.

According to a review by NBC, the Intel Core Ultra 7 155H falls short in both speed and power efficiency when compared to AMD’s year-old Ryzen 7 7840S. In various workloads such as content creation, productivity, and gaming, the Core Ultra 7 155H consistently lags behind its AMD counterpart. For instance, in Cinebench 2024, the Core Ultra 7 155H scores up to 747 points, while the Ryzen 7 7840S achieves a higher score of 853 points. Similar performance gaps are observed in other benchmarks like R23 and PCMark 10.

The power efficiency of the Core Ultra 7 155H is also notably lower than that of AMD’s Ryzen 7940HS. The Ryzen chip achieves up to 254 points per watt, while the Intel chip is limited to only 189.7 points per watt. This performance gap is particularly evident at lower power limits, with the multi-core deltas expanding to nearly 2,000 points in R23.

The disappointment continues when it comes to gaming performance. Despite being marketed as a key feature, the Xe-LPG Arc GPU on the Core Ultra 7 155H falls short of AMD’s Radeon 780M (R7 7840) in every game, with worse power efficiency. In popular titles like Dota 2, Final Fantasy XV, GTA V, and The Witcher 3, the Core Ultra 7 155H consistently underperforms compared to the Radeon 780M.

The power efficiency figures for the Core Ultra 7 155H’s iGPU are also disappointing. The Xe-LPG graphics score only 0.46 FPS per watt, while the Radeon 780M achieves nearly 0.6 FPS per watt. Overall, the Meteor Lake chips from Intel seem to lack the necessary performance and efficiency upgrades, making them a less appealing choice compared to AMD’s Ryzen 7000 series.

In conclusion, Intel’s 1st Gen Core Ultra CPUs have fallen behind AMD’s Ryzen 7000 chips in terms of both speed and power efficiency. Despite Intel’s efforts to introduce a modular architecture and leverage TSMC’s advanced process nodes, third-party reviews reveal that the Core Ultra 7 155H fails to deliver competitive performance in various workloads and gaming scenarios. With AMD’s Ryzen 7000 series offering superior performance and efficiency, Intel’s Meteor Lake chips may struggle to find a place in the market.

Technology Explained


GPU: GPU stands for Graphics Processing Unit and is a specialized type of processor designed to handle graphics-intensive tasks. It is used in the computer industry to render images, videos, and 3D graphics. GPUs are used in gaming consoles, PCs, and mobile devices to provide a smooth and immersive gaming experience. They are also used in the medical field to create 3D models of organs and tissues, and in the automotive industry to create virtual prototypes of cars. GPUs are also used in the field of artificial intelligence to process large amounts of data and create complex models. GPUs are becoming increasingly important in the computer industry as they are able to process large amounts of data quickly and efficiently.


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


Radeon: AMD Radeon, a product line by Advanced Micro Devices (AMD), consists of graphics processing units (GPUs) recognized for their strong performance in gaming, content creation, and professional applications. Powered by innovative technologies like the RDNA architecture, Radeon GPUs deliver efficient and powerful graphics processing. The brand also supports features like FreeSync, enhancing visual fluidity and reducing screen tearing during gaming. Moreover, AMD Radeon GPUs embrace real-time ray tracing for heightened realism in lighting and reflections. With a balance between price and performance, Radeon competes with NVIDIA's GeForce graphics cards and remains a popular choice for a wide range of users.


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.
