Let’s dive into a comprehensive comparison to find out.
Architecture: Zen 4 vs. Raptor Lake
The AMD Ryzen 9 8945HS is built on the latest Zen 4 architecture, boasting a significant leap in performance compared to its predecessors. This architecture features a refined design with improved instruction set extensions and a higher clock speed. On the other hand, the Intel Core Ultra 5 135U is based on the Raptor Lake architecture, which is an evolution of the Alder Lake design. This architecture introduces a new hybrid core design, combining high-performance P-cores with energy-efficient E-cores for optimal performance.
Core Count and Thread Count: A Close Race
Both CPUs are equipped with a significant number of cores and threads, making them suitable for demanding workloads. The AMD Ryzen 9 8945HS boasts 8 cores and 16 threads, while the Intel Core Ultra 5 135U packs 10 cores and 18 threads (6 P-cores and 4 E-cores). This means that both CPUs can handle multiple applications and tasks simultaneously without compromising performance.
Clock Speeds: Reaching New Heights
When it comes to clock speed, the AMD Ryzen 9 8945HS takes the lead. It boasts a base clock speed of 3.0 GHz and a boost clock speed of up to 5.2 GHz. The Intel Core Ultra 5 135U offers a base clock speed of 1.3 GHz and a boost clock speed of up to 5.0 GHz. However, it’s important to note that the Intel CPU‘s boost clock speed applies to the P-cores only, while the E-cores operate at a lower frequency.
Performance: Benchmarks and Real-World Usage
The AMD Ryzen 9 8945HS and Intel Core Ultra 5 135U demonstrate impressive performance in various benchmarks and real-world scenarios. In synthetic benchmarks like Cinebench R23, the AMD Ryzen 9 8945HS often scores higher in multi-core performance, showcasing its strength in multi-threaded workloads. However, the Intel Core Ultra 5 135U shines in single-core performance, which is crucial for tasks like gaming.
In real-world usage, both CPUs deliver smooth performance for everyday tasks like web browsing, document editing, and basic video editing. However, the AMD Ryzen 9 8945HS tends to excel in demanding tasks like 3D rendering, video editing, and gaming, thanks to its higher core count and clock speeds. The Intel Core Ultra 5 135U might struggle with these more intensive workloads due to its lower core count and reliance on E-cores.
Power Consumption and Battery Life: Efficiency Matters
Both CPUs are designed for mobile devices, so power consumption and battery life are crucial factors. The AMD Ryzen 9 8945HS utilizes a 45W TDP (Thermal Design Power), while the Intel Core Ultra 5 135U has a 15W TDP. This means that the Intel CPU is more energy-efficient and could potentially deliver longer battery life in laptops. However, the AMD Ryzen 9 8945HS can achieve higher performance due to its higher TDP, making it a suitable choice for users who prioritize performance over battery life.
Integrated Graphics: A Contested Battlefield
Both CPUs feature integrated graphics, making them capable of handling basic graphics tasks and even some light gaming. The AMD Ryzen 9 8945HS integrates the Radeon 780M graphics, while the Intel Core Ultra 5 135U features the Intel Iris Xe graphics. The Radeon 780M generally offers better performance than the Intel Iris Xe graphics, especially in demanding games. However, both integrated GPUs are not designed for high-end gaming and will struggle to deliver smooth frame rates in demanding titles.
Price and Availability: Finding the Right Value
When it comes to price, the AMD Ryzen 9 8945HS is typically more expensive than the Intel Core Ultra 5 135U. This price difference can be attributed to the higher performance and features offered by the AMD processor. However, the Intel Core Ultra 5 135U provides a more affordable option for users who prioritize value and battery life.
The Verdict: Choosing the Right CPU
The choice between the AMD Ryzen 9 8945HS and the Intel Core Ultra 5 135U ultimately depends on your individual needs and priorities. If you prioritize performance for demanding tasks like gaming, content creation, and multi-tasking, the AMD Ryzen 9 8945HS is the superior choice. Its higher core count, clock speeds, and integrated graphics deliver a significant performance advantage.
However, if you prioritize battery life, affordability, and a balance of performance, the Intel Core Ultra 5 135U is a compelling option. Its lower TDP, energy-efficient design, and lower price point make it a suitable choice for users who value efficiency and affordability.
Beyond the Benchmarks: The Bigger Picture
While performance benchmarks provide valuable insights, it’s important to consider other factors beyond raw CPU power. The overall performance of a laptop is influenced by various components, including RAM, storage, and the overall design of the device. Therefore, it’s crucial to compare the specifications of the entire laptop, not just the CPU, before making a decision.
The Future of Mobile Computing: A New Era of Innovation
The AMD Ryzen 9 8945HS and Intel Core Ultra 5 135U represent the latest advancements in mobile computing. As technology continues to evolve, we can expect even more powerful and efficient CPUs in the future. These advancements will further blur the lines between desktop and mobile computing, enabling users to enjoy high-performance computing on the go.
