Unverified50% confidenceFactExact time
Graphcore's IPU uses a large-SRAM architecture; SRAM provides high bandwidth and low latency, but for trillion-parameter models capacity becomes a hard constraint, and accommodating the model by adding more chips brings cost, power, and time overhead.

Unverified片上SRAM提供了远超HBM的访问速度和带宽，消除了芯片到外部内存之间的数据搬运瓶颈75% similarUnverifiedIn the GPU memory hierarchy, SRAM is fast but has extremely limited capacity, while HBM has large capacity but relatively limited bandwidth.73% similarUnverifiedCPU-based TEE solutions (such as Intel SGX) restrict protected memory (EPC) to a small capacity, causing large model workloads to frequently trigger memory swapping, with performance overhead potentially reaching several times to tens of times.69% similar
