Tachyum today announced details about how its TDIMM is bringing the future of AI and computing, enabling AI models with parameters many orders of magnitude greater than those of any existing solution at a fraction of the cost. TDIMM is key to reducing the estimated cost of OpenAI data center $3 trillion and 250,000 megawatts of power to $27 billion and 540 megawatts.

Prodigy Ultimate provides up to 21x higher AI rack performance than NVIDIA Rubin Ultra NVL576. Tachyum DDR5 DIMM (TDIMM) bandwidth increase is 5.5 times, from 51 GB/s to 281 GB/s. Prodigy Ultimate's 24 channels provide 6.7 TB/s, 11x increase over 12-channel CPUs. The TDIMM supports 256 GB in standard, 512 GB in tall, and 1 TB in extra tall height, and TSV increases capacity up to 8 times to 3 PB per Prodigy node.
