I’ve seen the claim around but I’m highly skeptical of it. DDR5 is far too slow for anything where memory bandwidth really matters, any newly produced chip that’s gonna be used for AI is on HBM3 or HBM3e, or possibly GDDR6/GDDR7 if it’s a GPU pulled from the consumer segment. HBM5 is still a very, very early research project and is certainly not being produced yet.
