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
One of the major changes with VR NVL72 is within the compute tray
