Quick Answer
The integrated graphics (iGPU) in AMD’s Ryzen 7000 series processors, known as Radeon Graphics, generally offer significantly higher performance than Intel’s older UHD Graphics 620. The Radeon Graphics iGPU is based on a more modern architecture, supports newer display and encoding technologies, and is capable of handling more demanding light gaming and creative tasks. The UHD Graphics 620, while sufficient for basic desktop use, is considered a legacy solution for everyday productivity.
Radeon Graphics iGPU (Ryzen 7000) vs Intel UHD Graphics 620: Full Comparison
Introduction
When evaluating a laptop or desktop for everyday use, the integrated graphics processor (iGPU) is a critical component that influences everything from display smoothness to light gaming capability. This comparison examines two distinct generations of iGPU technology: the modern Radeon Graphics found in AMD’s Ryzen 7000 series desktop and mobile processors, and the older Intel UHD Graphics 620 commonly found in 8th and 10th generation Intel Core processors. Understanding their differences in architecture, performance, and features can help clarify what to expect from systems built around these technologies.
Architecture and Technology
The fundamental difference between these iGPUs lies in their underlying architecture and the era they represent.
- Radeon Graphics (Ryzen 7000): This iGPU is based on AMD’s RDNA 2 architecture, the same technology found in many modern discrete gaming graphics cards. It features up to 2 Compute Units (CUs) on desktop “Raphael” CPUs and more on mobile “Phoenix” APUs. This architecture supports advanced features like hardware-accelerated ray tracing and variable rate shading.
- Intel UHD Graphics 620: This iGPU is based on Intel’s Gen9.5 architecture, which is several generations old. It is a part of the aging “Kaby Lake R” and “Whiskey Lake” microarchitectures. Its technology is focused on basic display output and video acceleration, lacking support for many contemporary gaming and rendering features.
The architectural gap means the Radeon Graphics solution is built on a more efficient and capable foundation designed for modern workloads.
Performance and Gaming
Performance is the most significant point of separation. Benchmarks typically show a substantial gap in graphical compute power.
- Radeon Graphics: This iGPU can handle light gaming at 720p and even 1080p low settings in many popular esports titles like Valorant, League of Legends, and CS:GO. It also provides a smoother experience in general desktop use, including basic photo editing and video playback.
- UHD Graphics 620: Performance is limited to very basic 3D tasks. It may run older or extremely lightweight games at low resolutions and settings, but it struggles with modern titles. Its primary strength is driving displays for office applications, web browsing, and video streaming.
For any task beyond basic productivity and media consumption, the Radeon iGPU typically provides a more responsive and capable experience.
Display and Media Support
Both iGPUs can drive multiple displays, but they support different sets of modern standards.
- Radeon Graphics: Supports DisplayPort 2.1 and HDMI 2.1 on modern platforms, enabling output to high-resolution, high-refresh-rate monitors. It also features AV1 video decode acceleration, which is becoming the new standard for streaming services, improving efficiency and battery life during playback.
- UHD Graphics 620: Supports older standards like HDMI 1.4 and DisplayPort 1.2. It lacks AV1 decode support, relying on older codecs like H.264 and HEVC. This can lead to higher CPU usage when playing back newer AV1-encoded content.
The Radeon Graphics iGPU offers more future-proof connectivity and media playback capabilities.
Power Efficiency and Use Cases
The intended use case and system design are important differentiators.
- Radeon Graphics (Ryzen 7000): Found in both modern desktop CPUs and efficient mobile APUs. In mobile “Phoenix” APUs, it is paired with a powerful CPU core and a more advanced manufacturing process, offering a strong balance of CPU and GPU performance for thin-and-light laptops.
- UHD Graphics 620: Almost exclusively found in older laptop CPUs and some low-power desktop chips. Systems using this iGPU are generally older models focused on maximum battery life for basic tasks, not graphical performance.
Choosing a system with UHD Graphics 620 today typically means opting for an older, often more affordable platform, while Ryzen 7000 with Radeon Graphics represents a current-generation solution.

Frequently Asked Questions (FAQ)
What is the main performance difference between these iGPUs?
The Radeon Graphics iGPU in Ryzen 7000 processors typically offers 2 to 4 times the graphical performance of Intel’s UHD Graphics 620 in synthetic benchmarks and real-world gaming. This makes it viable for light modern gaming, whereas the UHD 620 is suited only for basic display output and very old games.
Can Intel UHD Graphics 620 handle 4K video playback?
Yes, the UHD Graphics 620 has hardware decoding for HEVC/H.265 and VP9 codecs, so it can play 4K video from streaming services like Netflix and YouTube without overloading the CPU. However, it does not support the newer AV1 codec, which may lead to software decoding and higher power use for AV1 content.
Which iGPU is more power-efficient?
Efficiency depends on the specific processor and system design. Modern Ryzen 7000 mobile APUs with Radeon Graphics are built on more advanced manufacturing processes (4nm/6nm), which generally offer better performance per watt. Older systems with UHD Graphics 620 (14nm) may have lower absolute power draw but also significantly lower performance.
Do I need a separate graphics card if I have Ryzen 7000 with Radeon Graphics?
Not necessarily for everyday tasks. The Radeon Graphics iGPU is sufficient for web browsing, office applications, media consumption, and light gaming. A discrete graphics card is generally only required for demanding gaming, professional 3D rendering, or high-resolution video editing.
Final Thoughts
This comparison highlights a clear generational shift in integrated graphics technology. The Radeon Graphics solution within AMD’s Ryzen 7000 series represents a modern iGPU designed for contemporary workloads, offering competent light gaming, support for the latest display and media standards, and integration into current-generation platforms. In contrast, Intel’s UHD Graphics 620 is a capable but aging solution that serves well for basic computing needs in older systems. The choice between platforms featuring these graphics options often comes down to whether one prioritizes access to modern features and better graphical performance or is considering a system where the overall platform cost and basic functionality are the primary concerns.
