Architect's technical teardown: VRAM capacity, memory bandwidth, TDP, and AI throughput — compared head-to-head for local LLM workloads.
High value 12GB performer. Excellent efficiency and enough VRAM for 8B models with high-context K-V cache needs.
Affordable unified memory. A highly capable entry-level LLM workstation perfectly suited for developer desks.
