Architect's technical teardown: VRAM capacity, memory bandwidth, TDP, and AI throughput — compared head-to-head for local LLM workloads.
The Blackwell prosumer sweet spot. GDDR7 bandwidth delivers exceptional tokens-per-second for 30B+ parameter models in a single-GPU configuration.
High-efficiency inference engine. 16GB of VRAM allows for local hosting of Llama 3 70B (distilled) and high-speed Qwen 2.5 workflows.
