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.
The most affordable 16GB NVIDIA card. Perfect for local AI hobbyists wanting access to larger VRAM pools without the ultra-premium price.
