AMD Ryzen 7 8845HS vs AMD Ryzen 7 8745HS: Full Comparison
Introduction
When evaluating laptops, particularly in the performance-focused segment, the processor is a critical component. AMD’s Ryzen 7 8000HS series offers compelling options for thin-and-light gaming laptops and mobile workstations. This comparison breaks down the specifications and capabilities of two models from this series: the Ryzen 7 8845HS and the Ryzen 7 8745HS. Understanding their subtle differences can help in making an informed choice based on specific computing needs, especially regarding emerging AI workloads.
Architecture and Core Specifications
Both processors are built on the same “Hawk Point” architecture, which is an optimized refresh of the “Phoenix” design. They share identical foundational specs, making them more similar than different.
- CPU Cores/Threads: Both chips feature 8 cores and 16 threads, utilizing a hybrid design with “Zen 4” performance cores.
- Clock Speeds: They share the same base and boost clock frequencies. The base clock is typically 3.8 GHz, with a maximum boost clock up to 5.1 GHz.
- Manufacturing Process: Both are fabricated on a 4nm process node.
- Thermal Design Power (TDP): Configured within a 35-54W range, making them suitable for similar laptop chassis designs focused on performance and portability.
In terms of raw CPU performance for traditional tasks like gaming, content creation, and multitasking, users can expect nearly identical results from both processors.
Graphics and Gaming Performance
The integrated graphics solution is another area of parity between these two APUs (Accelerated Processing Units).
- GPU Model: Both integrate the AMD Radeon 780M graphics.
- Compute Units: They feature the full 12 RDNA 3 Compute Units (CUs).
- Clock Speed: The graphics engine runs at the same frequency, typically up to 2.7 GHz.
This means for gaming, video playback, and light GPU-accelerated tasks, the experience should be virtually the same. Performance in these areas will be more dependent on system factors like cooling, RAM configuration (especially dual-channel and speed), and driver support rather than the choice between these two specific CPUs.
AI and NPU Performance
This is the primary differentiator between the Ryzen 7 8845HS and the Ryzen 7 8745HS. Both processors include a dedicated Neural Processing Unit (NPU) for handling AI workloads locally on the device.
- Ryzen 7 8845HS NPU: This model is equipped with an NPU rated at 16 TOPS (Trillions of Operations Per Second).
- Ryzen 7 8745HS NPU: This model features an NPU rated at 10 TOPS.
The higher TOPS rating of the 8845HS suggests it can process AI-related tasks more quickly. These tasks include features like Windows Studio Effects (background blur, eye contact), AI-assisted noise cancellation, local language model processing, and other machine learning applications that benefit from on-device processing for privacy and latency reasons. For users who frequently use such AI-enhanced features, the 8845HS may provide a snappier experience.
Platform and Feature Support
Being part of the same product family and generation, both processors support an identical set of modern platform features.
- Memory Support: Both support DDR5 and LPDDR5/x memory, with the same maximum speeds and dual-channel architecture.
- Connectivity: They integrate the same modern connectivity options, including support for Wi-Fi 6E and Bluetooth 5.3.
- Display Support: They offer the same display output capabilities, generally supporting multiple 4K displays.
- PCIe Support: Both provide the same number of PCIe lanes (typically PCIe 4.0) for connecting storage and discrete graphics.
