Jan 4, 2023 The philosophy behind each system
What makes these systems fascinating is how they reflect the strategies of their makers.
Huawei is leaning heavily on its Ascend 950 chips and a custom interconnect called UnifiedBus 2.0 - the emphasis is on building out compute density at an extraordinary scale, then networking it together seamlessly.
Nvidia has spent years refining its DGX line and now offers the DGX SuperPOD as a turnkey solution, integrating GPUs, CPUs , networking, and storage into
a balanced environment for enterprises and research labs.
AMD is preparing to join the conversation with the Instinct MegaPod, which aims to scale around its future MI500 accelerators and a brand-new networking fabric called UALink.
While Huawei talks about exaFLOP levels of performance today, Nvidia highlights a stable, battle-tested platform, and AMD pitches itself as the challenger offering superior scalability down the road.
At the heart of these clusters are heavy-duty processors built to deliver immense computational power and handle data-intensive AI and HPC workloads.
Huaweis Atlas 950 SuperPoD is designed around 8,192 Ascend 950 NPUs, with reported peaks of 8 exaFLOPS in FP8 and 16 exaFLOPS in FP16 - so it is
clearly aimed at handling both training and inference at an enormous scale.
Nvidias DGX SuperPOD, built on DGX A100 nodes, delivers a different flavor of performance - with 20 nodes containing a total of 160 A100 GPUs, it looks smaller in terms of chip count.
However, each GPU is optimized for mixed precision AI tasks and paired with high-speed InfiniBand to keep latency low.
AMDs MegaPod is still on the horizon, but early details suggest it will pack 256 Instinct MI500 GPUs alongside 64 Zen 7 Verano CPUs.
While its raw compute numbers are not yet published, AMDs goal is to rival or exceed Nvidias efficiency and scale, especially as it uses next-generation PCIe Gen 6 and 3-nanometer networking ASICs.
Feeding thousands of accelerators requires staggering amounts of memory and interconnect speed.
Huawei claims the Atlas 950 SuperPoD carries more than a petabyte of memory, with a total system bandwidth of 16.3 petabytes per second.
This kind of throughput is designed to keep data moving without bottlenecks across its racks of NPUs.
Nvidias DGX SuperPOD does not attempt to match such headline numbers, instead relying on 52.5 terabytes of system memory and 49 terabytes of high-bandwidth GPU memory, coupled with InfiniBand links of up to 200Gbps per node.
The focus here is on predictable performance for workloads that enterprises already run.
AMD, meanwhile, is targeting the bleeding edge with its Vulcano switch ASICs offering 102.4Tbps capacity and 800Gbps per tray external throughput.
Combined with UALink and Ultra Ethernet, this suggests a system that will surpass current networking limits once it launches in 2027.
One of the biggest differences between the three contenders lies in how they are physically built.
Huaweis design allows for expansion from a single SuperPoD to half a million Ascend chips in a SuperCluster.
There are also claims that an Atlas 950 configuration could involve more than a hundred cabinets spread over a thousand square meters.
Nvidias DGX SuperPOD takes a more compact approach, with its 20 nodes integrated in a cluster style that enterprises can deploy without needing a stadium-sized data hall.
AMDs MegaPod splits the difference, with two racks of compute trays plus one dedicated networking rack, showing that its architecture is centered around a modular but powerful layout.
In terms of availability, Nvidias DGX SuperPOD is already on the market, Huaweis Atlas 950 SuperPoD is expected in late 2026, and AMDs MegaPod is planned for 2027.
That said, these chips are fighting very different battles under the same banner of AI supercomputing supremacy.
Huaweis Atlas 950 SuperPoD is a show of brute force, stacking thousands of NPUs and jaw-dropping bandwidth to dominate at scale, but its size and proprietary design may make it harder for outsiders to adopt.
Nvidias DGX SuperPOD looks smaller on paper, yet it wins on polish and reliability, offering a proven platform that enterprises and research labs
can plug in today without waiting for promises.
AMDs MegaPod, still in development, has the makings of a disruptor, with its MI500 accelerators and radical new networking fabric that could tilt the balance once it arrives, but until then, it is a challenger talking big.
