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).

Prices are current as of April 2025. Check for availability with official AMD partners.

Memory Bus

The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.

Bandwidth

Memory bandwidth refers to the data transfer rate between the graphics chip and the video memory. It is measured in bytes per second, and the formula to calculate it is: memory bandwidth = working frequency × memory bus width / 8 bits.

ROPs

The Raster Operations Pipeline (ROPs) is primarily responsible for handling lighting and reflection calculations in games, as well as managing effects like anti-aliasing (AA), high resolution, smoke, and fire. The more demanding the anti-aliasing and lighting effects in a game, the higher the performance requirements for the ROPs; otherwise, it may result in a sharp drop in frame rate.
