AMD’s next-generation MI200 HPC GPU is finally here and the new product is codenamed Aldebaran that uses a 6nm CDNA 2 architecture to deliver insane compute performance.

With the launch of this GPU, AMD became the first to launch MCM technology and the Aldebaran GPU will come in various forms & sizes but it’s all based on the brand new CDNA 2 architecture which is the most refined variation of Vega.

AMD Instinct™ MI200 Series GPUs announced with up to 128GB of HBM2e memory

Some of the main features before we go into detail are listed below:

  • AMD CDNA 2 architecture – 2nd Gen Matrix Cores accelerating FP64 and FP32 matrix operations, delivering up to 4X the peak theoretical FP64 performance vs. AMD previous-gen GPUs.
  • Leadership Packaging Technology – Industry-first multi-die GPU design with 2.5D Elevated Fanout Bridge (EFB) technology delivers 1.8X more cores and 2.7X higher memory bandwidth vs. AMD previous-gen GPUs, offering the industry’s best aggregate peak theoretical memory bandwidth at 3.2 terabytes per second.
  • 3rd Gen AMD Infinity Fabric technology – Up to 8 Infinity Fabric links connect the AMD Instinct MI200 with 3rd Gen EPYC CPUs and other GPUs in the node to enable unified CPU/GPU memory coherency and maximize system throughput, allowing for an easier on-ramp for CPU codes to tap the power of accelerators.

The GPU features two dies, a secondary and a primary and both consist of 8 shader engines for a total of 16 SE’s. Each Shader Engine packs 16 CUs with full-rate FP64, packed FP32 & a 2nd Generation Matrix Engine for FP16 & BF16 operations.

Each die also consists of 128 compute units or 8192 stream processors which brings us to a total of 220 compute units or 14,080 stream processors for the entire chip.

Built on AMD CDNA 2 architecture, AMD Instinct MI200 series accelerators deliver leading application performance for a broad set of HPC workloads. The AMD Instinct MI250X accelerator provides up to 4.9X better performance than competitive accelerators for double precision (FP64) HPC applications and surpasses 380 teraflops of peak theoretical half-precision (FP16) for AI workloads to enable disruptive approaches in further accelerating data-driven research.
