AMD Radeon RX 6300: Budget GPU for Compact Systems and Basic Tasks

April 2025

Architecture and Key Features

The AMD Radeon RX 6300 graphics card is built on the RDNA 3 Lite architecture—a simplified version of the flagship RDNA 3 tailored for the budget segment. The chip is manufactured using TSMC's 6nm process, providing a balance between energy efficiency and cost.

Unique Features:

- FidelityFX Super Resolution 3.0 (FSR): Upscaling technology that increases FPS in games with minimal loss of detail. Supports Quality, Balanced, and Performance modes.

- Hybrid Ray Tracing: Basic support for ray tracing, but with limited performance due to the small number of RT cores.

- Radeon Anti-Lag+: Reduces input lag in competitive games.

The architecture is optimized for DirectX 12 Ultimate and Vulkan but is not designed for heavy real-time computations.

Memory: Compact Capacity and Narrow Bus

The RX 6300 is equipped with 4 GB of GDDR6 memory with a 64-bit bus. The bandwidth reaches 112 GB/s (memory clock speed of 14 GHz). This is sufficient for playing games at low and medium settings at 1080p, but scenes with highly detailed textures or enabling RTX may lead to stuttering due to a lack of VRAM.

Tip: For comfortable gaming in projects from 2023 to 2025 (such as Starfield or GTA VI), it is recommended to reduce texture quality to Medium.

Gaming Performance: 1080p as the Primary Format

In tests, the RX 6300 shows the following results (average FPS, Medium/High settings):

- Cyberpunk 2077 (FSR 3.0 Quality): 45–55 FPS (1080p, no ray tracing).

- Fortnite (DX12): 60–70 FPS (1080p Epic, with FSR).

- Apex Legends: 75–85 FPS (1080p High).

- Hogwarts Legacy: 35–45 FPS (1080p Medium, RTX disabled).

Ray tracing reduces performance by 30–40%, so it is only worth activating in less demanding projects (such as Minecraft RTX). The card is not suitable for 1440p or 4K resolutions—even with FSR, the frame rate drops below 30 FPS.

Professional Tasks: Limited Specialization

The RX 6300 is positioned as a solution for basic work tasks:

- Video Editing: Handles rendering in DaVinci Resolve and Premiere Pro (H.264/H.265) at up to 1080p resolution.

- 3D Modeling: Works in Blender and Maya on low-polygon projects, but a more powerful GPU is required for complex scenes.

- Scientific Calculations: OpenCL support allows the card to be used in machine learning (at the level of student projects), but the 4 GB of memory and weak computational power limit its application.

Important: For professional tasks, models with 8+ GB of memory are preferable (such as the RX 6600 or NVIDIA RTX 3050).

Power Consumption and Cooling

The RX 6300 has a TDP of 75W, allowing it to operate without additional power—powered through PCIe x16. The cooling system is passive or equipped with a single fan, making the GPU ideal for compact cases (Mini-ITX).

Recommendations:

- Use a case with at least one exhaust fan for heat dissipation.

- If overclocking (if supported), set a thermal limit of 80°C via Radeon Software.

Comparison with Competitors

- NVIDIA GeForce RTX 2050 (6 GB): Priced at $180, offering DLSS 2.0 and better ray tracing support, but lagging in energy efficiency.

- Intel Arc A380: Priced at $160, 6 GB of GDDR6. Stronger in Vulkan projects but weaker in DirectX 12.

- AMD Radeon RX 6400: At $170, provides 8 GB of memory but similar performance.

Conclusion: The RX 6300 ($150) is the choice for those seeking minimal cost and compactness.

Practical Assembly Tips

- Power Supply: A 400W unit is sufficient (e.g., Corsair CV450).

- Compatibility: PCIe 4.0 x8, requires a motherboard with UEFI.

- Drivers: Update Adrenalin Edition quarterly—AMD is actively optimizing FSR for new games.

Pros and Cons

Pros:

- Low price ($150).

- Energy efficiency.

- Compact design.

- Support for FSR 3.0.

Cons:

- Only 4 GB of VRAM.

- Weak performance in RTX scenes.

- Limited memory bandwidth.

Final Verdict: Who is the RX 6300 Suitable For?

This graphics card is a good option for:

1. Budget gamers playing at 1080p on medium settings.

2. Owners of small form factor PCs (HTPC, office builds).

3. Users needing a temporary GPU for basic tasks.

If you are willing to spend an extra $30–50, it’s better to opt for the RX 6400 or RTX 2050. But for modest needs, the RX 6300 remains one of the most affordable solutions in 2025.

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.
