Context Before
However, Nvidia began exploring HBM-equipped variants for prefill, either via modified CPX configurations or through lower memory spec (such as using HBM3E) Rubin deployments dedicated to prefill.
Evidence
We also think a lot this shift is driven by evolving memory economics.
Context After
Conventional DRAM pricing has risen sharply: As DDR pricing increases, the relative premium of HBM compresses because pricing is more locked down in long term contracts, narrowing the cost gap between a GDDR-based CPX and lower-spec HBM configurations, therefore eliminating a lot of the cost benefits GDDR offers relative to performance. While memory bandwidth is not as important for pre-fill compare to decode, it is still necessary.
② Atomic Claim
SemiAnalysis 也認為，這項轉變很大一部分是由持續變化的 memory economics 所驅動。
