Context Before

The MI400 Series scale-up network will use Broadcom Ethernet Tomahawk 6 switches because Marvell and Astera Labs’ UALink switches will not be ready by late 2026

Evidence

Despite these earlier points, the MI400 Series with UALink over Ethernet will still be competitive with the VR200 NVL144’s NVLink in terms of scale up bandwidth and also has a scale up world size of 72 logical GPUs

Context After

In late 2027, AMD will release the MI500 UAL256 which will feature 256 physical/logical chips and not just 144 physical/logical chips like in VR300 NVL576

② Atomic Claim

SemiAnalysis 預期 MI400 UALoE 在 scale-up bandwidth 上仍可與 VR200 NVL144 NVLink 競爭，且 world size 為 72 logical GPUs。
