AMD Radeon E9390 PCIe

AMD Radeon E9390 PCIe: Power and Efficiency for Gamers and Professionals
April 2025
1. Architecture and Key Features
RDNA 4: A Breakthrough in Energy Efficiency
The AMD Radeon E9390 is based on the RDNA 4 architecture, manufactured using TSMC's 4nm process. This has allowed a 20% increase in transistor density compared to RDNA 3, while maintaining a moderate TDP. A key feature is the improved Ray Accelerators 2.0, delivering ray tracing with minimal FPS loss.
Technologies for Gamers and Creators
- FidelityFX Super Resolution 3.5: Upscaling to 4K with AI smoothing, increasing FPS by 50-70% in "Quality" mode.
- Hybrid Ray Tracing: Combining traditional rendering with ray tracing for a balance between quality and performance.
- Smart Access Storage: Accelerating texture loading in DirectStorage-compatible games (e.g., Starfield: Odyssey).
2. Memory: Speed and Capacity
GDDR6X with 16 GB and 384-bit Bus
The graphics card is equipped with GDDR6X memory operating at 20 Gbps, providing a bandwidth of 768 GB/s. This amount (16 GB) is ideal for 4K gaming and handling heavy projects in Blender or Unreal Engine 5.
Why is this Important?
- In Cyberpunk 2077: Phantom Liberty (4K, Ultra), the E9390 uses 12-14 GB of memory, avoiding stutters.
- For editing 8K video in DaVinci Resolve, the memory reserve allows for smooth performance without cache overloads.
3. Performance in Games: Numbers and Reality
1080p and 1440p: Maximum Settings
- Call of Duty: Black Ops VI (1440p, Ultra, FSR 3.5 Quality): 142 FPS.
- Assassin’s Creed: Nexus (1080p, Ultra + Hybrid RT): 98 FPS.
4K: Challenge Accepted
- Horizon Forbidden West PC Edition (4K, Ultra, FSR 3.5 Balanced): 68 FPS.
- With full Ray Tracing enabled in Alan Wake 3 (4K, Medium RT), FPS drops to 44, but with FSR 3.5 it rises to 60.
Ray Tracing: Not Without Compromises
Ray Accelerators 2.0 reduce performance loss by 30% compared to RDNA 3, but for comfortable 4K with RT, it's better to enable FSR.
4. Professional Tasks: Not Just Gaming
3D Rendering and AI
- In Blender (Cycles), the E9390 is 15% faster than the NVIDIA RTX 4070 Ti due to optimization for OpenCL.
- For scientific calculations using ROCm 4.5, the card demonstrates 12.4 TFLOPS in FP32.
Video Editing
- Rendering an 8K project in Premiere Pro takes 20% less time than the RTX 4080, thanks to hardware encoding support for AV1.
5. Power Consumption and Thermal Output
TDP 250 W: Not the Most Power-Hungry
A recommended power supply is 650 W (for a system with Ryzen 7 8700X). The card uses 8+6-pin connectors.
Cooling
- The reference model with a triple-fan and vacuum chamber keeps temperatures under 72°C under load.
- For compact cases, it's better to choose custom solutions from Sapphire (Nitro+) or PowerColor (Red Devil).
6. Comparison with Competitors
NVIDIA RTX 4070 Ti Super
- E9390 Pros: +4 GB memory, better scaling in OpenCL, price $649 vs. $799.
- Cons: RTX wins in ray tracing with DLSS 4.0 (+10-15% FPS).
AMD Radeon RX 8800 XT
- The E9390's sibling is difficult to call a competitor: the RX 8800 XT is 8% slower at 4K but cheaper ($599).
7. Practical Advice
Power Supply and Compatibility
- Minimum of 650 W (preferably with 80+ Gold certification).
- PCIe 5.0 x16 is essential for fully utilizing the GDDR6X memory.
Drivers and Optimization
- The Adrenalin Edition 2025 automatically adjusts FSR for the monitor. For professionals, the Pro Driver is recommended for improved OpenCL stability.
8. Pros and Cons
✅ Strengths
- Ideal for 1440p/4K gaming with FSR.
- Best-in-class support for OpenCL.
- Competitive pricing ($649).
❌ Weaknesses
- Ray tracing requires compromises.
- Reference cooling is noisy at 45 dB.
9. Final Conclusion: Who is the E9390 for?
Gamers looking to play in 4K without upgrading for the next 3-4 years will appreciate the balance of price and power. Professionals working with rendering and editing will benefit from 16 GB of memory and OpenCL optimization.
Alternatives?
- If maximum RTX is needed, consider the RTX 4070 Ti Super.
- For pure gaming at 1440p, the RX 8800 XT will suffice.
The AMD Radeon E9390 is a versatile choice, where every dollar spent translates into performance "here and now."
