AMD Radeon Pro 450: A Professional Tool for Creatives and Enthusiasts

April 2025

Introduction

The AMD Radeon Pro 450 is an updated mobile graphics card introduced in 2025, designed for professionals and users who prioritize stability, energy efficiency, and support for modern technologies. Despite its compact form factor, it delivers balanced performance in work tasks and moderate gaming capabilities. In this article, we will explore who this model is suitable for and what secrets its architecture hides.

1. Architecture and Key Features

Architecture: The Radeon Pro 450 is built on a hybrid platform RDNA 3+, combining elements of RDNA 3 and optimizations for professional applications. This allows the card to function efficiently with both graphic editors and computational tasks.

Manufacturing Process: 6 nm (TSMC) — the reduced transistor size ensures low power consumption and moderate heat generation.

Unique Features:

- FidelityFX Super Resolution 3.0 — enhanced upscaling for gaming and rendering.

- Radeon ProRender — built-in support for photorealistic rendering.

- Hybrid Ray Tracing — simplified ray tracing for modeling and visualization (not for gaming).

The card does not support hardware Ray Tracing at the level of NVIDIA RTX, but thanks to driver optimizations, it handles basic tasks well.

2. Memory

Type and Size: 8 GB GDDR6 with a 128-bit bus.

Bandwidth: 224 GB/s — sufficient for working with medium-sized 3D models and editing video at resolutions up to 4K.

Impact on Performance:

- For 1080p gaming, the memory is adequate even for high-quality textures.

- In professional applications (like Blender or AutoCAD), the memory allows for processing scenes with 5–7 million polygons without data loading delays.

3. Gaming Performance

The Radeon Pro 450 is not a gaming card, but in 2025, it performs well with less demanding projects:

- Cyberpunk 2077 (FSR 3.0, Quality): 45–50 FPS at 1080p (Low), 30 FPS at 1440p.

- Fortnite (DX12): 60–70 FPS at 1080p (Medium).

- Apex Legends: 75–80 FPS at 1080p (High).

Ray Tracing: Due to the lack of specialized RT cores, enabling Hybrid Ray Tracing reduces FPS by 40–50%. For games with RTX, it's better to look at NVIDIA models like RTX 3050 and above.

4. Professional Tasks

Here, the Radeon Pro 450 fully reveals its potential:

- Video Editing: Rendering a 4K video in DaVinci Resolve takes about 25% less time compared to the integrated graphics of Ryzen 7 8700G.

- 3D Modeling: In Autodesk Maya, the card handles scenes with 10 million polygons without lag.

- Scientific Calculations: Support for OpenCL 3.0 and ROCm 5.5 makes it suitable for basic-level machine learning (e.g., data processing in MATLAB).

Comparison with CUDA: In tasks dominated by NVIDIA CUDA (e.g., Adobe Premiere Pro), the Radeon Pro 450 lags behind competitors like RTX A2000 by 15–20%.

5. Power Consumption and Heat Output

TDP: 65 W — the card is suitable for slim laptops and compact PCs.

Cooling: Passive or active system with one fan. For stable performance in rendering, a case with 2–3 additional coolers is recommended.

Assembly Tips:

- Minimum power supply: 400 W (for PCs with Ryzen 5 level processors).

- In laptops, a quality heat dissipation module is essential — avoid ultrabooks with passive cooling.

6. Comparison with Competitors

- NVIDIA RTX A2000 (8 GB): 25% faster in compute tasks but more expensive ($450 versus $300 for Radeon Pro 450).

- AMD Radeon RX 7600M: Gaming alternative at a similar price, but without optimizations for professional software.

- Intel Arc A580: Cheaper ($250) but weaker in OpenCL applications.

Conclusion: The Radeon Pro 450 is the choice for those who need stable drivers and support for pro software.

7. Practical Tips

- Power Supply: 400–450 W with an 80+ Bronze certification.

- Compatibility: It works with PCIe 4.0 but doesn't require separate power — suitable for mini-PCs.

- Drivers: Update through AMD Pro Software — they are more stable than the gaming Adrenalin Edition.

Important: In macOS, the card shows better optimization than in Windows due to tight integration with the Metal API.

8. Pros and Cons

Pros:

- Low power consumption.

- Support for professional APIs (OpenCL, Metal).

- Affordable price ($300–$350).

Cons:

- Weak Ray Tracing.

- Limited gaming performance.

- No support for AV1 encoding.

9. Final Verdict: Who is the Radeon Pro 450 Suitable For?

This graphics card is the ideal choice for:

1. Designers and editors working in Adobe Suite or Blender on laptops.

2. Engineers who need stability in CAD applications.

3. Students looking for a budget solution for studies and hobby projects.

For gamers or machine learning specialists, it is better to look at more powerful models. However, if you need a reliable, quiet, and economical card for work — the Radeon Pro 450 will be a faithful companion.

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.
