Context Before
We also think a lot this shift is driven by evolving memory economics. **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.
Compute Tray Redesign
Evidence
This redesign of the compute tray is centered around simplifying assembly, namely eliminating cables from the compute tray as cables have been the major point of failure of GB200/300 assembly

② Atomic Claim
compute tray redesign 的核心是簡化 assembly，尤其是移除 compute tray 內的 cables，因 cables 一直是 GB200/300 assembly 的主要故障點。
