AMD Ryzen 7 8745HS vs AMD Ryzen 7 8700G: Full Comparison
Introduction
When evaluating AMD’s Ryzen 7 series, understanding the distinction between mobile and desktop variants is crucial. The Ryzen 7 8745HS and the Ryzen 7 8700G, while sharing the “Ryzen 7” branding, are engineered for fundamentally different computing environments. This comparison aims to clarify their architectures, performance profiles, and ideal use cases, helping users determine which processor aligns with their specific needs, whether for a high-performance laptop or a compact desktop system.
Architecture and Platform
The most fundamental difference between these two processors is their target platform, which dictates their design philosophy.
- AMD Ryzen 7 8745HS: This is a mobile processor built on the “Hawk Point” architecture, part of the 8040 series. The “HS” suffix denotes a high-performance chip designed for thin-and-light gaming and creator laptops. It operates within a configurable thermal design power (TDP) range, typically starting around 35W, to balance performance with battery life and thermal constraints in a portable chassis.
- AMD Ryzen 7 8700G: This is a desktop APU (Accelerated Processing Unit) from the “Phoenix” family, launched in the 8000G series for the AM5 socket. As an APU, it places a stronger emphasis on its integrated Radeon 780M graphics. It has a higher default TDP of 65W, allowing it to sustain higher clock speeds when paired with adequate cooling in a desktop environment.
This platform distinction means they are not interchangeable; the 8745HS is soldered onto laptop motherboards, while the 8700G is a socketed chip for DIY desktop builds.
CPU Performance and Core Configuration
Both processors share a similar core foundation built on AMD’s Zen 4 architecture, but with different clock speed optimizations.
- Core/Thread Count: Both the Ryzen 7 8745HS and the Ryzen 7 8700G feature 8 cores and 16 threads. This makes them highly capable for multitasking, productivity applications, and gaming.
- Clock Speeds: Here, the desktop-oriented 8700G generally holds an advantage. It typically features higher base and boost clock speeds to leverage the better power delivery and cooling potential of a desktop PC. The mobile 8745HS has lower base clocks to manage heat and power consumption in a laptop, though its boost clocks can be aggressive for short bursts.
- Cache: Both chips feature 24MB of total cache (L2+L3), ensuring fast data access for the CPU cores.
For sustained multi-threaded workloads like video rendering or code compilation in a well-cooled system, the 8700G will typically have a performance edge. The 8745HS is designed to deliver strong performance within the strict thermal limits of a laptop.
Integrated Graphics (iGPU) Performance
This is a major area of differentiation, especially for the Ryzen 7 8700G.
- AMD Ryzen 7 8700G: It is equipped with the Radeon 780M graphics based on the RDNA 3 architecture, with 12 Compute Units (CUs). This is currently one of the most powerful integrated graphics solutions available. It can handle 1080p gaming at medium to high settings in many modern titles and is an excellent choice for a desktop build where a discrete graphics card is not desired.
- AMD Ryzen 7 8745HS: It also features Radeon 780M graphics. However, its performance in a laptop is constrained by the system’s thermal design and power limits. While still the most capable iGPU in the mobile segment, it may not sustain the same peak clock speeds as its desktop counterpart. Laptops with this chip also commonly include a discrete GPU for serious gaming.
The 8700G’s primary value proposition is its desktop-class integrated graphics, making it a unique part. The 8745HS’s iGPU is powerful for a laptop but often plays a secondary role to a discrete GPU.
Power Efficiency and Use Cases
The intended use case is the ultimate deciding factor between these two processors.
- AMD Ryzen 7 8745HS Use Case: Designed for premium thin-and-light gaming laptops, high-performance ultrabooks, and mobile workstations. It is the right choice for users who need a balance of strong CPU performance, good battery life, and portability. Its performance is realized within the context of a complete laptop system.
- AMD Ryzen 7 8700G Use Case: Aimed at desktop users building small form factor (SFF) PCs, budget gaming rigs without a discrete GPU, or highly efficient office/Home Theater PC (HTPC) systems. It is ideal for those who want capable 1080p gaming and strong CPU performance without the cost and space requirements of a separate graphics card.

Frequently Asked Questions (FAQ)
Can I upgrade my laptop with an AMD Ryzen 7 8700G?
No. The AMD Ryzen 7 8700G is a desktop processor for the AM5 socket. Laptop processors like the Ryzen 7 8745HS are permanently soldered to the motherboard and cannot be upgraded or swapped.
Which processor has better gaming performance?
In a system without a discrete graphics card, the Ryzen 7 8700G will typically deliver better gaming performance due to its higher sustained power limit in a desktop. However, laptops featuring the Ryzen 7 8745HS almost always include a discrete GPU (like an RTX 4050 or 4060), which will far surpass the gaming capability of any integrated graphics, including the 8700G’s.
Are the integrated graphics (Radeon 780M) the same in both chips?
While they share the same name, architecture (RDNA 3), and core count (12 CUs), their real-world performance differs. The 8700G’s iGPU can run at higher clock speeds with better cooling in a desktop, while the 8745HS’s iGPU performance is limited by the laptop’s thermal design and power budget.
Is the Ryzen 7 8745HS good for content creation?
Yes. With its 8-core/16-thread Zen 4 architecture, it is a very capable mobile processor for tasks like video editing, 3D rendering, and photo editing. Performance will depend on the specific laptop’s cooling solution and power settings.
Final Thoughts
The choice between the AMD Ryzen 7 8745HS and the Ryzen 7 8700G is primarily dictated by the form factor you require.
