NVIDIA Blackwell Consumer GPU Launch: Major Boost in Local AI Inference, Lower Barrier for Developers

NVIDIA has launched the Blackwell series consumer GPUs (RTX 5090/5080), delivering approximately 4x improvement in AI inference performance over the previous generation. With 16GB VRAM as standard, running 70B parameter models locally is now feasible. More importantly, the new GPUs feature dedicated optimizations for INT4 quantization inference, enabling large models like Qwen2.5-72B to achieve usable speeds on ordinary PCs. This is expected to further fuel the local AI development boom.
