Context Before

We also think a lot this shift is driven by evolving memory economics.

Evidence

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

Context After

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

傳統 DRAM 價格大幅上漲；隨 DDR 價格上升，HBM 因長約定價較固定，其相對 premium 被壓縮，使 GDDR-based CPX 與……之間的 cost gap 縮小。
