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.
16-core Zen 4 performance. High memory bandwidth and multi-threaded strength make it a top choice for Linux AI software stacks.
