RTX 4090 vs RTX 5090: How Much Faster is the Next-Gen GPU?

Nvidia’s release of the GeForce RTX 5090, the flagship of its new Blackwell series, has set the tech world abuzz with discussions about its performance compared to its predecessor, the RTX 4090. With the same core fabrication technology but an expanded architecture, the 5090 pushes the boundaries of GPU performance. Let’s explore the generational leap, real-world benchmarks, and the potential impact of Nvidia’s advanced DLSS 4 frame generation in this RTX 4090 vs RTX 5090 comparison.

Familiar Tech, Bigger Scale

Unlike previous generational leaps, Nvidia has retained the 4nm fabrication process used for the RTX 4090. However, the RTX 5090 expands its architecture with a massive 744 mm² processor, a 33% increase in CUDA cores, a 512-bit memory interface, and a jump to 32GB of GDDR6X memory. These enhancements deliver a significant 77% boost in memory bandwidth and substantial increases in shader performance.

This upgrade comes at a cost: the RTX 5090 consumes up to 575 watts, a 28% increase in power usage compared to the 4090’s already demanding 450 watts. The high power draw, combined with the 5090’s immense processor size, positions it as a halo product for hardcore enthusiasts. Despite these increases, Nvidia managed to fit this powerhouse into a sleek, two-slot chassis, even suitable for small form factor PCs—a feat of industrial design.

Performance Gains: RTX 4090 vs RTX 5090

In terms of raw performance, the RTX 5090 offers a 22% to 38% improvement over the RTX 4090, averaging a 31% generational uplift. While not as dramatic as the 60-80% leap seen when transitioning from the 3090 to the 4090, this increase is still a meaningful upgrade for those seeking the absolute best in performance.

Key Benchmarks:

1. Cyberpunk 2077 (4K, Psycho RT Mode):
   • RTX 5090: 35 FPS (native), 286 FPS (DLSS 4 with 4x frame generation)
   • RTX 4090: ~27 FPS (native)
     The 5090 showcases a 30% increase over the 4090 in native rendering and significant gains with DLSS 4 enabled.
2. Alan Wake 2 (Ray Tracing, Max Settings):
   • RTX 5090 is 35% faster than the RTX 4090, delivering smoother gameplay with improved frame pacing and consistency.
3. Hitman (Non-RT, 4K):
   • The RTX 5090 boasts a 53% performance gain over AMD’s Radeon 7900 XTX and nearly 4x the performance of the older RX 6900 XT.
4. F1 2024:
   • With ray tracing disabled, the RTX 5090 delivers 30% more performance than the 4090, while drawing more power at peak workloads.

These results highlight that while the RTX 5090 is a clear winner in performance, the differences narrow at lower resolutions, reinforcing its role as a 4K or even 8K powerhouse.

DLSS 4: A New Frontier

Nvidia’s DLSS (Deep Learning Super Sampling) has been a game-changer, and DLSS 4 takes it a step further. By combining super resolution and multi-frame generation, DLSS 4 enables massive frame rate boosts in demanding titles. For example, in Cyberpunk 2077, DLSS 4 transforms a native frame rate of 35 FPS into 286 FPS—a staggering 8x improvement.

However, this technology is not without controversy. Frame generation introduces additional latency (approximately 9-10 milliseconds), which could be a concern for esports gamers who rely on ultra-responsive controls. Despite these drawbacks, the smoothness and visual fluidity offered by DLSS 4 make it a compelling feature for AAA titles, particularly for 4K gaming.

A Halo Product for Enthusiasts

The RTX 5090 cements itself as the king of GPUs, but it comes with a hefty price tag of USD $2,000. For many, the upgrade decision hinges on what they already own:

• RTX 3090/3090 Ti Owners: The 5090 offers roughly 2x the performance, making it a worthy upgrade for those looking to future-proof their setups.
• RTX 4090 Owners: With only a 25-30% performance improvement, upgrading may not make financial sense unless the additional power is critical for specific workloads.

The Future of PC Gaming

The RTX 5090 illustrates a shift in the GPU industry. As the cost of improving raw hardware performance escalates, software-based solutions like DLSS 4 will play a larger role. Nvidia’s focus on machine learning and AI-driven technologies echoes trends across the gaming and tech landscapes, from consoles like the PS5 Pro to PC hardware.

While the RTX 5090’s performance leap over the RTX 4090 might not be revolutionary, its innovations in DLSS 4 and design efficiency set the stage for the future of GPUs. It’s clear that Nvidia’s latest flagship is not just a GPU; it’s a glimpse into what lies ahead for PC gaming.

In the battle of RTX 4090 vs RTX 5090, the latter is a clear winner in raw power and technological advancements, but it also raises important questions about the future of GPU design and the balance between hardware and software innovations. For enthusiasts with the budget to spare, the RTX 5090 is the ultimate upgrade for 4K and beyond.
