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.
Affordable unified memory. A highly capable entry-level LLM workstation perfectly suited for developer desks.
