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

Evidence

lower-spec HBM configurations, therefore eliminating a lot of the cost benefits GDDR offers relative to performance.

Context After

While memory bandwidth is not as important for pre-fill compare to decode, it is still necessary.
