The Nvidia GeForce RTX 5090: A Leap Forward, But For Whom?

Nvidia's latest flagship, the RTX 5090, promises a generational leap in PC gaming performance. However, the reality is more nuanced. While raw power is significantly boosted, the performance gains over the RTX 4090 are less dramatic than expected in many games, especially without DLSS Frame Generation. The true innovation lies in the next-generation DLSS 4, which dramatically improves both image quality and frame rates through AI-powered upscaling and frame generation.

The RTX 5090's value proposition hinges heavily on your gaming setup and preferences. For those with anything less than a high-end 4K monitor (240Hz or higher), the upgrade is unlikely to justify the cost. However, for owners of such displays, the AI-generated frames offered by DLSS 4 provide a glimpse into the future of gaming.

RTX 5090 – Specifications and Features

Built on Nvidia's Blackwell architecture (already powering leading AI models), the RTX 5090 excels in AI-related tasks. However, traditional gaming performance hasn't been neglected. The card boasts 21,760 CUDA cores (a 32% increase over the RTX 4090), significantly boosting raw processing power. Each Streaming Multiprocessor (SM) includes four Tensor Cores and one RT Core, resulting in 680 Tensor Cores and 170 RT cores. The 5th-generation Tensor Cores support FP4 operations, reducing VRAM dependency for AI workloads.

The card features 32GB of GDDR7 VRAM, a generational upgrade offering improved speed and power efficiency compared to GDDR6X. Despite this, the RTX 5090 consumes a substantial 575W, a significant increase over the RTX 4090's 450W.

DLSS 4's reliance on a Transformer Neural Network (TNN) instead of a Convolutional Neural Network (CNN) aims to enhance image quality and reduce artifacts. The introduction of Multi-Frame Generation, an evolution of DLSS 3's Frame Generation, allows for the generation of multiple frames from a single rendered image, drastically increasing frame rates. However, like its predecessor, it's most effective when paired with a solid base frame rate (around 60fps or higher).

Purchasing Guide

The Nvidia GeForce RTX 5090 launched January 30th, with a starting price of $1,999 for the Founders Edition. Third-party cards are expected to be considerably more expensive.

The Founders Edition

Despite its 575W power consumption, the RTX 5090 Founders Edition surprisingly features a smaller, dual-slot design with dual fans. Cooling performance is impressive, with temperatures peaking around 86°C even under heavy load (578W). This is achieved through a redesigned PCB layout and a unique airflow system that draws air from the bottom and expels it through the top. The card maintains a similar aesthetic to previous generations, featuring a silver 'X' design and illuminated GeForce RTX logo.

A new, angled 12V-2x6 power connector (with included adapter for four 8-pin PCIe connectors) improves upon the previous generation's design, aiming to address past power connector issues.

DLSS 4: Beyond "Fake Frames"

While the RTX 5090's raw performance is impressive, DLSS 4's Multi-Frame Generation is its defining feature. A new AI Management Processor (AMP) core efficiently manages workload distribution across the GPU, enabling a frame generation model that's 40% faster and 30% more memory-efficient than its predecessor. The AMP also employs a Flip Metering algorithm to minimize input lag.

Initial testing in Cyberpunk 2077 and Star Wars Outlaws (beta builds) showed remarkable results, with frame rates exceeding 280fps in 4K with DLSS 4 enabled. While the technology isn't magic (requiring a good base frame rate for optimal performance), it's undeniably effective for high-refresh-rate, high-resolution displays. Nvidia claims support for 75 games at launch.

RTX 5090 – Performance Benchmarks

Benchmarking revealed a generational leap in raw performance in 3DMark, with up to a 42% improvement over the RTX 4090. However, real-world gaming performance showed a more limited advantage. In many titles, even at 4K, the RTX 5090 was bottlenecked by the CPU (Ryzen 7 9800X3D), resulting in smaller performance gains (often under 10%) compared to the RTX 4090. The exception was games that heavily utilize ray tracing or lack upscaling options, where the RTX 5090 demonstrated a more substantial performance lead. One outlier was Assassin's Creed Mirage, which experienced driver-related performance issues.

Conclusion

The Nvidia GeForce RTX 5090 is undeniably powerful, currently the fastest consumer graphics card available. However, its generational leap is primarily driven by DLSS 4's Multi-Frame Generation. For those with high-end 4K displays seeking maximum frame rates, the RTX 5090 is a compelling choice. For others, the RTX 4090 remains a highly capable alternative, offering excellent performance at a significantly lower price. The RTX 5090 is a bet on the future of AI-enhanced gaming; a future that is undeniably impressive, but not yet fully realized in current game titles.
