Architect's technical teardown: VRAM capacity, memory bandwidth, TDP, and AI throughput — compared head-to-head for local LLM workloads.
The previous generation's king. 24GB VRAM and high CUDA counts remain the industry standard for consumer AI development.
The budget Blackwell entry. Optimized for 12B-14B models with the latest tensor cores for FP4 precision support.
