AMD Radeon RX 6700S
AMD Radeon RX 6700S: In-Depth Analysis of the Graphics Card for Gamers and Professionals
April 2025
Since the release of the RDNA 2 architecture, AMD has continued to strengthen its position in the graphics solutions market. The Radeon RX 6700S, launched in 2023, remains a relevant choice for those seeking a balance between price, performance, and energy efficiency. Let's explore what makes it stand out in 2025 and who it is suitable for.
1. Architecture and Key Features
RDNA 2 Architecture: Optimization for Gaming and Multimedia
The RX 6700S is built on the RDNA 2 architecture, which succeeded RDNA 1. This platform brought significant IPC (instructions per clock) improvements of up to 30% compared to its predecessor. The card utilizes a 6nm process technology from TSMC, which has reduced power consumption without sacrificing performance.
Unique Features:
- Ray Accelerators: Hardware blocks for ray tracing (up to 28 units), which accelerate the rendering of realistic shadows and reflections.
- FidelityFX Super Resolution (FSR): Image scaling technology supporting FSR 3.0, which adds frame generation for increased FPS. By 2025, FSR is operational in more than 90 games, including Cyberpunk 2077 and Starfield.
- Radeon Anti-Lag+: Reduces input lag in games by 15-20%, which is critical for esports.
Lack of DLSS 4.0 Equivalent: Unlike NVIDIA, AMD has not yet implemented neural network algorithms at the level of DLSS 4.0, but FSR 3.0 remains a competitive solution for monitors with refresh rates up to 144 Hz.
2. Memory: Fast GDDR6 and Data Flow Optimization
Type and Volume: The RX 6700S features 10 GB of GDDR6 memory with a 160-bit bus. This is sufficient for gaming at resolutions up to 1440p, but 4K or heavy RT usage may result in shortages.
Bandwidth: 320 GB/s is a modest figure compared to the NVIDIA RTX 4070 (504 GB/s), but Infinity Cache technology (80 MB) mitigates this by reducing latencies by up to 30%.
Impact on Performance:
- In Hogwarts Legacy (1440p, Ultra), the cache reduces FPS drops during rapid location changes.
- For editing 4K video in DaVinci Resolve, 10 GB of memory is adequate for medium complexity projects, but for 8K rendering, cards with 16+ GB are recommended.
3. Gaming Performance: Real Numbers
1080p (Full HD):
- Apex Legends (Ultra): 144 FPS.
- Elden Ring (Max, RT off): 85 FPS.
- Call of Duty: Modern Warfare IV (DLSS/FSR off): 110 FPS.
1440p (QHD):
- Cyberpunk 2077 (Ultra, FSR 3.0 Quality): 68 FPS.
- Starfield (High, RT on): 45 FPS.
4K (UHD):
- Forza Horizon 5 (Ultra, FSR 3.0 Performance): 60 FPS.
- Assassin’s Creed Nexus (Medium): 48 FPS.
Ray Tracing:
- Enabling RT reduces FPS by 35-50%. For example, in Metro Exodus Enhanced Edition (1440p), the figure drops from 75 to 40 FPS. For comfortable gameplay with RT, activating FSR 3.0 is recommended.
4. Professional Tasks: Not Just Gaming
Video Editing:
- In Adobe Premiere Pro (PugetBench), the RX 6700S scores 820 points, which is 15% lower than the RTX 4060 Ti due to optimization for CUDA.
- Support for AV1 encoding via AMD AMF speeds up video exports by 20% compared to H.264.
3D Modeling:
- In Blender (Cycles), rendering a BMW scene takes 4.2 minutes compared to 3.1 minutes with the RTX 4070.
- The card is suitable for work in Maya or ZBrush, but professionals should consider the Radeon Pro series.
Scientific Computing:
- Support for OpenCL and ROCm 5.5 allows for GPU usage in machine learning, but libraries like TensorFlow are optimized less effectively than for CUDA.
5. Power Consumption and Heat Dissipation
TDP: 135 W — this is 25% lower than the RX 6800 but 10% higher than the RTX 4060.
Recommendations:
- Power Supply: At least 550 W (for a system with Ryzen 5 7600X).
- Cooling: A dual-slot cooler handles the load, but in compact cases (up to 20 liters), temperatures can reach 80°C. An optimal option is a case with 3-4 fans.
Overclocking: The frequency can be increased from 2.4 GHz to 2.7 GHz, but the gain will only be 5-8% FPS.
6. Comparison with Competitors
AMD Radeon RX 7600 XT:
- Pros: 12 GB GDDR6, support for DisplayPort 2.1.
- Cons: Price $450 versus $370 for RX 6700S.
NVIDIA GeForce RTX 4060:
- Pros: DLSS 4.0, better RT performance (+25%).
- Cons: 8 GB GDDR6, starting price $400.
Intel Arc A770:
- Pros: 16 GB memory, price $350.
- Cons: Low driver stability for older games.
7. Practical Tips
Power Supply: Choose models with an 80+ Bronze certification or higher (Corsair CX550, EVGA 600 GD).
Compatibility:
- Platforms: Ideally paired with Ryzen 5/7 7000-series processors.
- Ports: 1x HDMI 2.1, 3x DisplayPort 2.0 — supports up to 4 monitors.
Drivers: Adrenalin Edition 2025 offers automatic overclocking and fine-tuning of RGB lighting (for models from ASUS or Sapphire).
8. Pros and Cons
Pros:
- Optimal price ($370-400) for QHD gaming.
- Energy efficiency.
- Support for FSR 3.0 and AV1.
Cons:
- Limited capabilities for ray tracing.
- 10 GB of memory is the minimum for 2025.
9. Final Conclusion: Who is the RX 6700S Suitable For?
This graphics card is an excellent choice for:
1. Gamers who play at 1440p and are willing to reduce RT settings for stable FPS.
2. Content creators working on amateur-level video editing and 3D modeling.
3. Owners of compact PCs who value quiet operation and moderate power consumption.
If you are not chasing ultra settings in 4K and want to save $100-150, the RX 6700S remains a cost-effective option even in 2025. However, for professional tasks focused on rendering or AI, it’s better to consider the NVIDIA RTX 4070 or Radeon Pro W7700.
