Architect's technical teardown: VRAM capacity, memory bandwidth, TDP, and AI throughput — compared head-to-head for local LLM workloads.
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.
The previous generation's king. 24GB VRAM and high CUDA counts remain the industry standard for consumer AI development.
