The semiconductor specialists from SemiAnalysis predict that AMD will equip a “Mega Pod” with a whopping 256 MI500 GPU. These are divided into two racks together with CPU of the Verano type, in addition there is another rack with switches. However, this counterpart to Nvidia’s SuperPod is not expected until the end of 2027.
256 MI500 GPU Specs and Price
The chart published via X illustrates the current estimate of the company SemiAnalysis, which is known for comprehensive analyses in the semiconductor sector. The structure of the AMD “Mega Pod” alias “UAL256”, as the HPC system of the near future will be called at this point, can be seen. The two outer racks house the actual computing units, which are distributed over 32 trays. According to the scheme, one Epyc CPU with four 256 MI500 GPUs is used per tray. That makes 32 CPUs and 128 GPUs per rack and in a double pack that impressive amount of 64 CPUs and 256 MI500 GPUs.
The network switches are then to be used in the middle rack with 18 trays. The use of “Vulcano” as a new generation of network cards from the AMD Pensando family can be expected here. AMD announced such a system with a Verano CPU, MI500 and Pensando Vulcano for 2027 at the Advancing AI 2025 event last June. However, the above details about the equipment have not yet been confirmed.
According to SemiAnalysis, the AMD system would then offer more physical GPUs than Nvidia’s NVL576. The comparison is not very easy, after all, Nvidia Rubin uses four GPUs per package. This makes only 144 packages, but a total of 576 GPUs. How exactly MI500 is set up, however, remains to be seen.
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
The AI accelerators of the AMD Instinct MI500 series could also be used in the Pc Decode, which is also scheduled for 2027.
