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.
The ultimate budget entry card. 12GB of VRAM provides the vital headroom needed for Llama 3 and Stable Diffusion at minimum cost.
