Detailed Comparison

Architecture

The Ryzen 9 6900HX is based on AMD’s Zen 3+ architecture, while the Ryzen 9 7940HS is based on the newer Zen 4 architecture. Zen 4 offers a number of improvements over Zen 3+, including a new 5nm manufacturing process, a redesigned core architecture, and a larger L2 cache. These improvements result in better performance and power efficiency.

Cores and Threads

Both processors have 8 cores and 16 threads, which is the sweet spot for most users. This configuration provides a good balance of single-core and multi-core performance, making it suitable for a wide range of applications.

Clock Speeds

The Ryzen 9 7940HS has a slightly higher base clock (3.6 GHz vs 3.3 GHz) and boost clock (5.2 GHz vs 4.9 GHz) than the Ryzen 9 6900HX. This means that the Ryzen 9 7940HS will generally be faster in single-threaded applications, which are tasks that can only use one core at a time.

Cache

Both processors have 20 MB of cache, which is divided into L2 and L3 cache. The Ryzen 9 7940HS has a larger L2 cache (1 MB per core vs 512 KB per core), which can improve performance in applications that are heavily dependent on cache, such as games and video editing software.

Memory Support

Both processors support DDR5-4800 and LPDDR5-6400 memory. DDR5 memory is faster than DDR4 memory, and it can provide a significant performance boost in applications that are memory-intensive, such as video editing and 3D rendering.

PCIe Lanes

Both processors have 20 PCIe lanes, which can be used to connect to various components, such as graphics cards, storage devices, and Wi-Fi cards. The Ryzen 9 7940HS has 8 Gen 4 PCIe lanes and 12 Gen 3 PCIe lanes, while the Ryzen 9 6900HX has 8 Gen 4 PCIe lanes and 12 Gen 3 PCIe lanes. Gen 4 PCIe lanes are twice as fast as Gen 3 PCIe lanes, so the Ryzen 9 7940HS has a slight advantage in terms of connectivity.

Integrated Graphics

Both processors have integrated Radeon graphics, but the Ryzen 9 7940HS has a slightly more powerful Radeon 780M iGPU compared to the Radeon 680M iGPU in the Ryzen 9 6900HX. This means that the Ryzen 9 7940HS will be better suited for gaming and other graphics-intensive tasks.

Performance

In terms of performance, the Ryzen 9 7940HS typically outperforms the Ryzen 9 6900HX by 10-15% in single-core tests and 20-25% in multi-core tests. This is due to the Zen 4 architecture’s improvements in IPC (instructions per clock) and power efficiency.

In real-world applications, the Ryzen 9 7940HS is faster in gaming, content creation, and productivity tasks. For example, in gaming, the Ryzen 9 7940HS can achieve an average of 120 FPS in Cyberpunk 2077 at 1080p with high settings, while the Ryzen 9 6900HX can only achieve an average of 100 FPS.

In content creation, the Ryzen 9 7940HS can handle 4K video editing smoothly and can render complex 3D scenes in a reasonable amount of time. The Ryzen 9 6900HX can also handle these tasks, but it will take slightly longer.

In productivity tasks, the Ryzen 9 7940HS is also faster than the Ryzen 9 6900HX. For example, in office work and web browsing, the Ryzen 9 7940HS can handle multiple applications simultaneously without any lag.
