> NVIDIA unveils 8-way DGX Spark clusters and new Nemotron models at GTC Berlin, boosting AI inference performance by 40 percent.

At **GTC 2026 Berlin**, **NVIDIA** announced that **DGX Spark** platforms now support 8-way clusters, doubling the previous 4-way limit. This upgrade enables 128 GB systems to reach 1 TB of memory, while 64 GB configurations provide 512 GB for intensive AI workloads.

The company also launched the **Nemotron 3.5 Bolt** 74B 24GB model and Recursive Flint, a 40B MoE coding model optimized for RTX Spark. New RAM-efficient checkpoints were released for models like Qwen3.8-Flash-Next and GLM-5.3 to improve local hardware utility.

AI inference performance has increased by 40% on DGX and RTX systems. With 1 TB of memory, DGX Spark can now run models like GLM 5.3, while the **RTX PRO 6000 Blackwell** delivers a 40% uplift in Qwen 3.8 Flash-Next, significantly boosting local AI capabilities.
