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.
24-core Raptor Lake flagship. High P-core and E-core counts deliver excellent multi-threaded AI preprocessing, dataset tokenization, and concurrent model loading speeds.
