Graphcore details power for Bow AI unit
GraphCore详细介绍了其最新AI处理器的功耗，该处理器由第二代巨芯片和粘合的晶圆电源构建。
This Bow IPU has two wafers are bonded together to generate a new 3D die: one wafer for the AI processing, which is architecturally compatible with the GC200 IPU processor with 1,472 independent IPU-Core tiles, capable of running more than 8,800 threads and 900MB of In-Processor Memory
The second wafer adds deep trench capacitors and is bonded to the processor wafer next to the processing cores and memory to provide the higher performance, says Simon Knowles, co-founder and chief architect at Graphcore.
这使用了在TSMC开发的新技术，包括通过硅Via（BTSV）和Wafer-Wafer（WOW）混合键合的背面。
The Bow 2000 IPU provides up to 40% more performance with 16% better power efficiency for real world AI applications. The 1U unit integrated four of the new Bow processors with 3.6GB In-Processor-Memory and up to 256GB Streaming Memory with an average power of 1.25kW. This provides 1.4 petaFLOPs of AI compute.
In comparison, four of the same Mk2 chips without the wafer-on-wafer power management in the previous M2000 1U unit provides a peak performance of 1Pflop/s at 1.5kW.
Bow 2000是较大“ Pods”的构建块，从5U Bowpod16开始提供5.6 pflops。带有1024弓处理器的Bowpod 1024全机架单元将提供350个Pflops。

The power efficiency is allowing Graphcore to use the wafer on wafer technology to build a large scale AI machine 10 exaFLOPS of performance and 4Petabytes of memory and a bandwidth of 10 Pbyte/s
“Graphcore’s Bow POD systems set a new standard in artificial intelligence compute that will allow Atos customers to push their AI innovation further and achieve results faster than ever before,” said Agnès Boudot, Head of HPC & Quantum at French supercomputer developer Atos.
“随着模型的大小和复杂性的增长，图形和ATOS共同努力提供外部系统。同时，GraphCore对计算效率的不懈关注确保用户获得了AI投资的最佳回报，”她说。
US cloud service provider, Cirrascale, is making Bow Pod systems available today to customers as part of its Graphcloud IPU bare metal service, while European cloud service provider G-Core Labs has announced that it will be launching Bow IPU cloud instances in Q2 2022.
