Certainly an interesting choice. Dramatically worse performance but dramatically larger only time will tell how it actually goes

- schmorptron 1y agoRumor has it (according to MLID, so no one knows whether it's accurate) that AMD is also looking to use regular LPDDR memory for some of it's lower end next gen GPUs to not have to contend with nvidia over limited and cartelled GDDR7 supply. Maybe they're going to increase parallel bandwidth to compensate it? Or have wholly different tricks up their sleeve.

- magicalhippo 1y agoWith 160GB, surely they can add more channels to compensate?
- benob 1y agoIs there anything preventing them from using heterogeneous memory chips, like 1/4 GDDR7 and 3/4 LPDDR? It could enable new MEO-like architectures with finer-grained performance tuning for long contexts.
