Introduction

The landscape of PC gaming and graphics processing has been revitalized with NVIDIA's unveiling of the GeForce RTX 50 series at CES 2025. This new lineup, built on the Blackwell architecture, promises significant leaps in performance, efficiency, and AI capabilities over its predecessor, the RTX 40 series. Here, we delve into a detailed comparison, exploring specifications, performance metrics, technological advancements, and more.

Architecture and Manufacturing Process

  • RTX 40 Series: Built on the Ada Lovelace architecture, these GPUs utilize TSMC's 4nm process node, introducing third-generation RT cores and fourth-generation Tensor cores for enhanced ray tracing and AI performance.

  • RTX 50 Series: The Blackwell architecture takes a step forward, employing a refined version of TSMC's 4nm process, known as 4NP (NVIDIA Performance). This node offers better performance per watt, although not moving to a 3nm process as some anticipated. The RTX 50 series includes fifth-generation Tensor cores and fourth-generation RT cores, pushing the boundaries of AI and ray tracing further.

Key Specifications Comparison

1. CUDA Cores:

  • RTX 4090: 16,384 CUDA cores

  • RTX 5090: 21,760 CUDA cores

The RTX 5090 significantly increases the CUDA core count, enhancing parallel computing capabilities for gaming and professional applications.

2. Memory:

  • RTX 4090: 24GB GDDR6X, 384-bit memory bus

  • RTX 5090: 32GB GDDR7, 512-bit memory bus

The RTX 5090 not only offers more VRAM but also benefits from the faster GDDR7 memory, which supports a bandwidth increase to up to 1.8 TB/s thanks to a wider memory bus.

3. Clock Speeds and Power:

  • RTX 4090: Base clock 2.23 GHz, boost clock 2.52 GHz, TDP 450W

  • RTX 5090: Base clock not specified, boost clock up to 2.9 GHz, TDP 575W

The higher clock speeds of the RTX 5090, combined with an increased TDP, suggest a focus on raw performance, although this comes at the cost of higher power consumption.

4. AI and Ray Tracing Performance:

  • RTX 40 Series: Introduced DLSS 3 with frame generation.

  • RTX 50 Series: Features DLSS 4 with Multi Frame Generation, potentially doubling frame rates in supported applications, alongside enhanced ray tracing capabilities.

Features and Technologies

  • DLSS Evolution: From DLSS 3 in the RTX 40 series, which introduced frame generation, to DLSS 4 in the RTX 50 series, the technology now includes Multi Frame Generation, aiming for up to 8x performance increase in certain scenarios. This leap forward in AI-driven rendering is pivotal for next-gen gaming experiences.

  • Reflex 2 and Latency: The RTX 50 series introduces Reflex 2, which further reduces latency in competitive gaming scenarios by up to 75%, enhancing responsiveness.

  • Neural Rendering: With RTX 50, NVIDIA pushes for film-quality visuals in real-time gaming through neural rendering techniques, leveraging AI for more realistic lighting and reflections.

  • Encoding and Decoding: The RTX 50 series includes ninth-generation NVENC encoders and supports the 4:2:2 color format, offering an 11x increase in encoding speed for creators.

  • Max-Q for Laptops: For mobile gamers, the RTX 50 series brings significant improvements to battery life and thermal efficiency with new Blackwell Max-Q technologies.

Performance Gains

  • Gaming: Early benchmarks and NVIDIA's claims suggest that the RTX 5090 can outperform the RTX 4090 by at least 2x under DLSS 4, with non-DLSS performance gains estimated at 20-50%. This performance leap is attributed to higher core counts, faster memory, and improved architectural efficiencies.

  • Creative Workflows: For professionals, the RTX 50 series offers up to 2x faster performance in 3D rendering, video editing, and AI-driven content creation, thanks to the new Tensor cores and memory capabilities.

Pricing and Market Impact

  • Pricing: The RTX 5090 starts at $1,999, a significant jump from the RTX 4090's $1,599 launch price, reflecting the enhanced capabilities and power. Lower-tier models like the RTX 5080 and 5070 also see price increases but offer substantial performance improvements.

  • Market Impact: The RTX 50 series might redefine expectations for gaming and creative performance, potentially pushing competitors like AMD to innovate further or risk losing market share. However, the high pricing could also lead to a longer lifecycle for RTX 40 series cards as consumers weigh cost versus performance gains.

Future Outlook and Compatibility

  • Software Support: NVIDIA continues to enhance driver support and game compatibility, ensuring that the RTX 50 series can fully leverage its hardware capabilities. New AI models and tools are expected to be optimized for these GPUs.

  • Longevity and Upgradability: With PCIe Gen 5.0 support and DisplayPort 2.1, the RTX 50 series is future-proofed for new high-bandwidth, high-resolution displays and storage solutions.
