GTC 2025: The most important AI announcements

If you thought AI computing was already moving at breakneck speed, GTC 2025 just hit turbo mode. Nvidia unveiled game-changing advancements in AI hardware, software, and robotics—pushing boundaries in AI reasoning, inference acceleration, and 6G connectivity. With Blackwell Ultra, Dynamo, and GR00T N1, Nvidia isn’t just leading the AI revolution—it’s rewriting the rules. Let’s break down the biggest announcements.

Nvidia RTX Pro Blackwell series: AI and 3D work redefined

Nvidia has officially launched the RTX Pro Blackwell series at GTC 2025, introducing an unprecedented level of power for AI workloads and 3D processing. The flagship RTX Pro 6000 Blackwell for workstations features 96GB of GDDR7 memory, requiring 600 watts of power—an increase from the 575 watts of the RTX 5090. It boasts 24,064 CUDA cores, 512-bit memory bus, and 1792 GB/s memory bandwidth, supporting PCIe Gen 5 and DisplayPort 2.1.

This professional-grade GPU is tailored for game developers, AI professionals, and data-heavy workflows, coming in Max-Q and server variants. Nvidia has rebranded its professional GPU lineup under “RTX Pro,” replacing the previous Quadro series. The series includes RTX Pro 5000, 4000, and 4500 models for desktops and laptops, with up to 24GB of VRAM for laptop variants.

Key specifications:

• Fourth-Generation RT Cores for double the photorealistic rendering performance.
• Fifth-Generation Tensor Cores handling up to 4,000 AI trillion operations per second, with support for FP4 precision and DLSS 4 Multi Frame Generation.
• GDDR7 Memory scaling up to 96GB for professional workstations.
• Sixth-Generation NVIDIA NVDEC enhancing video processing.
• Multi-Instance GPU (MIG) for workload partitioning.

The RTX Pro 6000 will be available in April through PNY and TD Synnex, while OEMs like Dell, HP, and Lenovo will integrate it in May. Cloud providers including AWS, Google Cloud, and Azure will also adopt the GPU later this year.

Nvidia Dynamo: A 30x boost for AI inference

To address performance concerns with emerging AI models like DeepSeek R1, Nvidia unveiled Nvidia Dynamo, a parallel-processing AI inference software. This technology distributes AI workloads across up to 1,000 Nvidia GPUs, significantly increasing query throughput and efficiency.

According to Ian Buck, Nvidia’s head of hyperscale and high-performance computing, Dynamo delivers 30 times more performance using the same GPU count. This efficiency boost translates to 50 times more revenue potential for data centers utilizing Blackwell GPUs over previous Hopper-based architectures.

Additionally, Nvidia optimized DeepSeek R1 by reducing its floating-point precision to FP4, a move that increases efficiency without sacrificing accuracy. The Blackwell Ultra variant, an enhancement of the Blackwell 200, now includes 288GB of HBM3e memory and integrates with Grace CPUs in the NVL72 rack system for 50% better inference performance.

DGX Spark: The world’s smallest AI supercomputer

Nvidia introduced DGX Spark, a $3,000 personal AI supercomputer, marking a new era for desktop AI development. The device, previously codenamed “Digits,” is powered by the GB10 Blackwell Superchip, which delivers 1,000 trillion operations per second (TOPS).

Key specifications:

• 128GB of unified memory
• Up to 4TB of NVMe SSD storage
• Optimized for fine-tuning and AI inference tasks

For those needing higher performance, the DGX Station was also announced, featuring the GB300 Blackwell Ultra desktop superchip, capable of 20 petaflops of AI processing. Nvidia has partnered with Asus, Dell, HP, Boxx, Lambda, and Supermicro to launch variations of these systems.

Blackwell Ultra GB300: Nvidia’s next AI superchip

Expanding its AI hardware dominance, Nvidia unveiled the Blackwell Ultra GB300, shipping in late 2025. Despite not using a new architecture, it enhances the existing Blackwell series with 288GB of HBM3e memory and delivers 1.5x the FP4 inference performance of previous generations.

This chip forms the core of the NVL72 and NVL576 rack systems, dramatically improving AI model efficiency. Nvidia’s next-gen architectures, Vera Rubin (2026) and Rubin Ultra (2027), promise further scaling to 100 petaflops of FP4 performance.

GR00T N1: AI-Powered Robotics with Human-Like Cognition

Nvidia’s AI robotics push continues with the GR00T N1 foundation model, designed to mimic human cognition. It features:

• System 1 for fast-thinking, reflex-based actions
• System 2 for methodical, reasoning-based decisions
• Training on 780,000 synthetic trajectories for enhanced learning

The GR00T N1 model powers 1X Technologies’ humanoid robots, performing real-world tasks like household chores. Nvidia also introduced Newton, a physics engine co-developed with Google DeepMind and Disney Research, enabling precise robotic interactions.
