Features and Technology
Tracing Rays
Ray tracing on NVIDIA is more sophisticated and effective. The RTX 4090 boasts a better optimised design and a greater number of ray tracing cores. AMD’s RDNA 3 has improved, but the RX 7900 XTX still performs poorly in ray-traced workloads.
Upscaling: FSR versus DLSS
- Frame generation is included in DLSS 3.5 (RTX 4090), which provides more fluid gameplay even at low FPS levels. extensively used and included into numerous AAA games.
- Although more open, FSR 3 (RX 7900 XTX) is still lagging behind in adoption and does not perform as well in frame generation as DLSS.
Compute Tasks and AI
The RTX 4090 significantly surpasses the RX 7900 XTX in deep learning, AI inference, and CUDA-optimized professional content creation applications (e.g., Blender, DaVinci Resolve, TensorFlow) because of its Tensor cores. A similar feature set tailored to AI is not currently available from AMD.
Power Efficiency
- RX 7900 XTX: 355W TDP
- RTX 4090: 450W TDP
AMD produces less heat and requires a less taxing PSU because to its higher efficiency per watt.
Use Case Suggestions
RTX 4090:
- Top-tier 4K or 8K performance is required.
- For contemporary games, you depend on DLSS 3.5 and ray tracing.
- You use Blender, CUDA-accelerated jobs, or AI/ML apps.
RX 7900 XTX:
- You want top-tier gaming without shelling out more than $1,000.
- The majority of your gaming is done at rasterised 4K or 1440p settings.
- You want support for DisplayPort 2.1 and reduced power usage.
Benchmark Comparison

|---|---|---|
| 3DMark Time Spy (DX12) | ~30,396 | ~36,346 |
| Geekbench 6 (OpenCL) | ~224,686 | ~316,301 |
| PassMark G3D Mark | ~30,947 | ~38,586 |
Gaming Benchmarks (4K Ultra Settings)
| Game Title | RX 7900 XTX FPS | RTX 4090 FPS |
|---|---|---|
| Cyberpunk 2077 | 59 | 86 |
| Red Dead Redemption 2 | 102 | 124 |
| Assassin’s Creed Valhalla | 115 | 120 |
| Microsoft Flight Sim | 67 | 93 |
The RTX 4090 usually provides 20–35% higher frames per second in ray-traced environments and games with a lot of GPU usage. The performance difference closes in rasterised (non-ray-traced) applications, whereas the RX 7900 XTX provides high frame rates at a reduced price.
Pricing Value
| Card | Launch Price | Current Market Price |
|---|---|---|
| RX 7900 XTX | $999 | ~$950–$999 |
| RTX 4090 | $1,599 | ~$1,700–$2,000 |
Performance-per-dollar is more appealing with the RX 7900 XTX. Because of its high demand, the RTX 4090 is frequently priced higher than MSRP, particularly in countries with restricted supply.
Specifications

| Architecture | RDNA 3 | Ada Lovelace |
| Process Node | 5nm (GCD) + 6nm (MCD) | TSMC 4N |
| Transistor Count | 58 billion | 76.3 billion |
| Stream / CUDA Cores | 6,144 | 16,384 |
| Ray Tracing Cores | 96 | 128 |
| Tensor Cores | None | 512 |
| Base Clock | 1,855 MHz | 2,235 MHz |
| Boost Clock | 2,499 MHz | 2,520 MHz |
| VRAM | 24GB GDDR6 | 24GB GDDR6X |
| Memory Bus Width | 384-bit | 384-bit |
| Memory Bandwidth | 960 GB/s | 1,008 GB/s |
| TDP | 355W | 450W |
| Launch Price (USD) | $999 | $1,599 |
More AI-optimized CUDA and Tensor cores give the RTX 4090 an edge in compute-intensive circumstances. The RX 7900 XTX has DisplayPort 2.1 and improved power efficiency than the 4090’s 1.4a.
In conclusion
The performance leader is without a doubt the NVIDIA RTX 4090. It is perfect for pros and enthusiasts who require the finest, regardless of budget, because it excels in raw power, ray tracing, upscaling (DLSS), and AI workloads. However, the RX 7900 XTX offers 80–90% of the RTX 4090’s performance for 60% less money if you want pure gaming performance without ray tracing.
The 4090 is worthwhile if your workload benefits from sophisticated ray tracing, CUDA, or NVIDIA’s ecosystem. The RX 7900 XTX provides outstanding value if you want to keep your budget under $1,000 while still playing contemporary games at high resolutions.
