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.
Apple Silicon powerhouse. M4 Max unified memory architecture enables seamless CPU+GPU memory sharing — ideal for local LLM inference without discrete GPU complexity.
