AMD Radeon Pro V620: Power for Professionals and Enthusiasts
April 2025
Architecture and Key Features
RDNA 3 Pro: Hybrid for Workloads
The AMD Radeon Pro V620 is built on a hybrid RDNA 3 Pro architecture that combines elements of gaming (RDNA 3) and professional (CDNA 2) design. This allows it to effectively handle both graphical tasks and general-purpose computations. The manufacturing process is 5 nm from TSMC, ensuring high transistor density and energy efficiency.
Unique Features:
- FidelityFX Super Resolution 3 (FSR 3): AI-supported upscaling technology that boosts FPS in games by up to 2.5 times.
- Hybrid Ray Tracing: Second-generation hardware ray tracing with optimizations for real-time rendering.
- Infinity Cache Pro: 128 MB of L3 cache that accelerates memory operations.
- ROCm 5.5: Support for open computing for machine learning and scientific tasks.
Memory: Speed and Volume for Complex Projects
HBM2e: 32 GB with 1.8 TB/s Bandwidth
The Radeon Pro V620 comes equipped with 32 GB of HBM2e (High Bandwidth Memory). This solution provides a record-breaking bandwidth of 1.8 TB/s, which is critical for processing 8K video, rendering complex 3D scenes, and working with neural networks.
Impact on Performance:
- 8K Textures: Resource loading without delays in DCC applications (Blender, Maya).
- Scientific Calculations: Speeding up tasks in MATLAB or ANSYS by 20-30% compared to GDDR6 solutions.
Gaming Performance: Not Just for Work
Average FPS in Popular Titles (2025):
- Cyberpunk 2077 (4K, Ultra, Hybrid RT): 58 FPS (with FSR 3 – up to 85 FPS).
- Starfield (1440p, Ultra): 72 FPS.
- Horizon Forbidden West (1080p, Max): 120 FPS.
Features:
- Support for 4K/144 Hz: Perfect for gamers with high-end monitors.
- Ray Tracing: Hybrid RT falls short of NVIDIA DLSS 4 in detail but gains ground with FSR 3 in the FPS/quality balance.
Professional Tasks: The Purpose of Creation
Video Editing:
- DaVinci Resolve: Rendering an 8K project in 12 minutes (compared to 18 minutes with the RTX A6000).
- Premiere Pro: Smooth playback with real-time effects.
3D Modeling:
- Blender (OptiX vs. ROCm): On a scene with 10 million polygons, the V620 shows 14 FPS in real-time mode, while the RTX A6000 shows 16 FPS.
Scientific Calculations:
- CUDA vs. OpenCL: In molecular modeling tasks (GROMACS), the Radeon Pro V620 is 15% faster due to ROCm 5.5 optimizations.
Power Consumption and Heat Dissipation
TDP 300 W: System Requirements
- Cooling: A liquid cooling solution or top-tier air coolers (e.g., Noctua NH-D15) is recommended.
- Chassis: At least 3 expansion slots, with ventilation for front and top airflow.
Tips:
- Use a power supply rated at least 850 W (e.g., Seasonic PRIME GX-850).
- For builds with overclocked CPU/GPU — 1000 W.
Comparison with Competitors
AMD Radeon Pro V620 vs. NVIDIA RTX A6000 Ada:
- Memory: 32 GB HBM2e (1.8 TB/s) vs. 48 GB GDDR6X (960 GB/s).
- Rendering Performance: The V620 excels in memory-intensive tasks (+25%), while the A6000 performs better in ray tracing (+18%).
- Price: $3200 (V620) vs. $4500 (A6000).
Within the Brand:
- Radeon Pro W7900: Better for multi-monitor workstations but more expensive ($3800).
Practical Tips
Power Supply:
- Minimum 850 W with an 80+ Platinum rating.
- PCIe 5.0 (12VHPWR) cables for stability.
Compatibility:
- Platforms: Support for PCIe 5.0 (requires motherboards with AMD X670 or Intel Z890 chipsets).
- Drivers: Adrenalin Pro Edition 2025 with "Game Ready" and "Studio Stable" modes.
Considerations:
- For Linux: ROCm 5.5 is pre-installed in Ubuntu 24.04 LTS and Fedora 40 distributions.
Pros and Cons
Pros:
- 32 GB HBM2e for handling extreme workloads.
- Best price/performance ratio in the professional segment.
- Support for FSR 3 and Hybrid RT for gaming.
Cons:
- High power consumption.
- Limited availability (only through AMD partners).
- No hardware support for equivalents of DLSS 4.
Final Verdict: Who is the Radeon Pro V620 For?
This graphics card is designed for:
1. Professionals: Video editors, 3D artists, engineers needing stability and memory capacity.
2. Enthusiasts: Gamers and streamers juggling parallel tasks (gaming + rendering).
3. Laboratories: Scientific computing based on OpenCL and ROCm.
Why V620?
It offers a unique balance between professional capabilities and gaming performance for $3200, making it a compelling alternative to NVIDIA in 2025. However, for purely gaming PCs, it's better to choose the Radeon RX 8900 XT ($1200) or GeForce RTX 5090 ($1600).
