Context Before
LPU 3’s near reticle size die layout is very similar to LPU 1. a significant amount of area taken is up by the 500MB of on-chip SRAM, with a very small amount of area dedicated to MatMul cores that offer 1.2 PFLOPs of FP8 compute – a fraction of compute compared to Nvidia GPUs. This compares to LPU 1 with 230MB of SRAM and 750 TFLOPs of INT8, with the performance increase mostly driven by node migration from GF16 to SF4.
Evidence
As a single monolithic die, advanced packaging isn’t required.
Context After
One of the benefits of relying on SF4 is that it isn’t constrained like TSMC’s N3, which is putting a cap on accelerator production and is a key reason why the industry remains compute constrained. This is in addition to not having HBM which is also constrained. This allows Nvidia to ramp production of the LPU without sacrificing or eating into their valuable TSMC allocation or HBM allocations, representing true incremental revenue and capacity that noone else can access.
② Atomic Claim
由於採用單一 monolithic die，因此不需要先進 packaging。
