AMD has more Instinct MI200 series cards on the way for the HPC segment based on its brand new Aldebaran CDNA 2 GPU architecture. The latest card that's being talked about is the Instinct MI210 which features a single graphics compute die.
AMD Instinct MI210 To Feature A Single Aldebaran 'CDNA 2' GPU Compute Die With 6656 Cores & 64 GB HBM2E Memory
With the Instinct MI250X and MI250, AMD brought MCM technology to the data center and HPC segment. Based on its new CDNA 2 architecture, the new Aldebaran GPU offers immense power aimed at HPC and Data Center workloads. But there are more MI200 series cards on the horizon and the MI210 is one of them.
Playing with one @AMDInstinct MI210, BabelStream with HIP is around 40% more than MI100, seems great. #HPC #GPU

Yes, 104 CUs, 64 GB HBM2e

Oh thanks! It is close to 1.4 TB/s for all the kernels.

Unveiled by George Markomanolis, an Engineer working on the upcoming LUMI supercomputer & lead HPC scientist at CSC, who got remote access to the AMD Instinct MI210 boasts some impressive specs out of the box. George has shared that the Instinct MI210 features a single GCD which means it is a completely new SKU and doesn't feature both GCD dies on board the package. The single GCD is equipped with 104 CUs out of the 128 CUs featured on the Aldebaran chip. Even the higher-end MI250X features just 110 CUs enabled per die for a total of 7040 stream processors. The MI210 is housing 6656 stream processors.
In addition to the core count, the AMD Instinct MI210 also rocks 64 GB of HBM2e memory which is half the amount of the Instinct MI250X but twice the memory capacity over the Instinct MI100 and that was the flagship just a few months ago until it got replaced by the MI250 series. We don't have the exact Flops for this card but assuming it is clocked around the same 1700 MHz as the Instinct Mi250 accelerators are, we are looking at around 22-23 TFLOPs of FP64 and 44-46 TFLOPs of FP32 compute. This should give some heated competition to the NVIDIA A100 which isn't expected to get an update till GTC next year.
George has also shared that the AMD Instinct MI210 is around 40% faster than the Instinct MI100 in BabelStream with HIP. Given the cut-down specifications, we can expect the TDP to fall around 300-350W. And since this is a 1 GCD accelerator, we are also expecting to see a 4096-bit bus interface at 3.2 Gbps pin speeds for a total of 1.6 TB/s bandwidth. The MI210 accelerator should launch in both OAM and PCIe form factors and will start shipping to priority HPC customers and partners soon.
