How Powerful is the RTX 5090 Compared to the RTX 4090?
Just when you thought the RTX 4090 was the undisputed king of GPUs, Nvidia decided to break the limits yet again with the RTX 5090. The RTX 5090 isn’t just an incremental upgrade—it’s a massive leap forward, boasting 50–70% more performance than the RTX 4090. If you thought 4K gaming at 120 FPS was impressive, imagine 8K gaming at ultra settings with ray tracing enabled—without breaking a sweat!
So, what makes this GPU so much better? Let’s break down how the RTX 5090 architecture, graphical capabilities, AI computing potential, and even crypto mining efficiency make it the most powerful graphics card ever built.
RTX 5090 vs. RTX 4090: Architectural Advancements
Nvidia’s RTX 5090 is built on the new Blackwell architecture, which is a massive upgrade from the Ada Lovelace-based RTX 4090. Here’s what makes the RTX 5090 a next-gen beast:
- Smaller Process Node: The 5090 is rumored to be built on TSMC’s 3nm process (compared to the 4nm process of the 4090). This means higher efficiency, better thermals, and more power in a smaller space.
- Increased CUDA Cores: Early reports suggest the RTX 5090 could pack up to 24,000 CUDA cores, a huge jump from the 16,384 CUDA cores in the RTX 4090.
- Massive Memory Bandwidth: The 5090 may use 32 Gbps GDDR7 memory, up from 21 Gbps GDDR6X in the 4090, which means faster data access and better performance in gaming and AI tasks.
- Higher L2 Cache: Nvidia has reportedly doubled the L2 cache, which significantly reduces latency and boosts performance across workloads.
- PCIe 5.0 Support: Unlike the RTX 4090, which still relied on PCIe 4.0, the 5090 embraces PCIe 5.0 for faster communication between the GPU and CPU.
How the RTX 5090 Delivers the Best Graphics Ever
If you thought gaming graphics couldn’t get any better, Nvidia’s RTX 5090 is here to prove you wrong. Here’s how it dominates in visual fidelity and performance:
- 8K Gaming at Ultra Settings: The RTX 5090 can deliver 60+ FPS at 8K resolution with ray tracing and DLSS enabled. That’s console-shaming power!
- Ray Tracing 2.0: With more RT cores and AI-assisted ray tracing, lighting, shadows, and reflections now look even more lifelike, reducing performance dips seen in previous generations.
- DLSS 4.0: Deep Learning Super Sampling (DLSS) 4.0 will take AI-based upscaling to the next level, making lower resolutions look like native 8K while boosting FPS.
- Better VR Support: If you’re into VR, this GPU can power 4K per eye at 120Hz, ensuring buttery smooth experiences in next-gen VR titles.
How the RTX 5090 Benefits Gamers
If you’re a gamer, here’s what the RTX 5090 brings to the table:
✔ Higher FPS in AAA Games – Play Cyberpunk 2077, Starfield, and Red Dead Redemption 2 at 8K ultra settings.
✔ Smoother eSports Performance – Competitive games like Valorant, CS2, and Fortnite will hit 1000+ FPS on high-refresh-rate monitors.
✔ Future-Proofed for Years – With such power, you won’t need an upgrade for at least 5–7 years.
✔ No More Bottlenecks – The new PCIe 5.0 support ensures maximum CPU-GPU performance with no bottlenecking.
