The 16GB VRAM Threshold: The Minimum for Modern AI Work
When shopping for an AI graphics card in Kenya under KSh 150,000, the most critical specification is not clock speed—it is Video RAM (VRAM) capacity. Modern neural networks require weights and KV cache to reside entirely in GPU memory. Any model that overflows into system RAM over PCIe will crawl at 1/20th the speed.
