Evidence
BlueField-4’s design departs significantly from BlueField-3. Instead of doing a bespoke tapeout with compute and networking, NVIDIA simply reuses their large Grace CPU die, co-packaged with a ConnectX-9 die to make an 800G DPU with massive compute capabilities. 128GB of LPDDR5 feeds the Grace CPU at half the bandwidth of regular Grace. That is 4x the memory capacity of BlueField-3. BlueField-4 can also function as a storage controller, with four BF-4 chips in each Context Memory Storage system.

② Atomic Claim
NVIDIA 不再做 compute/networking 的 bespoke tapeout，而是重用大型 Grace CPU die，與 ConnectX-9 die co-package，形成具備大量 compute capability 的 800G DPU。
