Tesla just taped out the AI5 chip, huge milestone for FSD, Robotaxi & Optimus.

• Single AI5 delivers ~5x the real-world compute of a dual AI4 setup

• Massive leaps: ~8x compute power, 9x memory & 5x bandwidth vs current gen

• One chip matches Nvidia H100 performance for Tesla workloads; dual setup rivals Blackwell, but at way lower cost & power draw

• Radically simplified & optimized for edge AI inference (INT4/INT2/FP8 focus), perfect for cars & humanoid robots

• Full AI5 computer targets 2,000–2,500 TOPS (vs ~300–500 for AI4)

• “AI5 will make the cars almost perfect and greatly enhance Optimus”

• “AI5 will punch far above its weight” thanks to Tesla’s tightly co-designed hardware + software stack

Built in the USA (TSMC Arizona + Samsung Texas), with Terafab scaling up.

Congratulations @elonmusk and @Tesla
