Architect's technical teardown: VRAM capacity, memory bandwidth, TDP, and AI throughput — compared head-to-head for local LLM workloads.
The budget Blackwell entry. Optimized for 12B-14B models with the latest tensor cores for FP4 precision support.
Reliable 16GB VRAM performer. Great for high-speed inference on mid-sized language models and large-scale image generation.
