-[HBv4-series](hbv4-series.md) VMs are optimized for various HPC workloads such as computational fluid dynamics, finite element analysis, frontend and backend EDA, rendering, molecular dynamics, computational geoscience, weather simulation, and financial risk analysis. HBv4 VMs will feature up to 176 AMD EPYC™ 9004-series (Genoa) CPU cores, 688 GB of RAM, and no simultaneous multithreading. HBv4-series VMs also provide 800 GB/s of DDR5 memory bandwidth and 768MB L3 cache per VM, up to 12 GB/s (reads) and 7 GB/s (writes) of block device SSD performance, and clock frequencies up to 3.7 GHz.

HBv4 VMs feature up to 176 AMD EPYC™ 9V33X (GenoaX) CPU cores with AMD's 3D-V Cache, 768 GB of RAM, and no simultaneous multithreading. HBv4-series VMs also provide 780 GB/s of DDR5 memory bandwidth and  2304 MB L3 cache per VM, to 12 GB/s (reads) and 7 GB/s (writes) of block device SSD performance, and clock frequencies up to 3.7 GHz.
 
 All HBv4-series VMs feature 400 Gb/s NDR InfiniBand from NVIDIA Networking to enable supercomputer-scale MPI workloads. These VMs are connected in a non-blocking fat tree for optimized and consistent RDMA performance. NDR continues to support features like Adaptive Routing and the Dynamically Connected Transport (DCT). This newest generation of InfiniBand also brings greater support for offload of MPI collectives, optimized real-world latencies due to congestion control intelligence, and enhanced adaptive routing capabilities. These features enhance application performance, scalability, and consistency, and their usage is recommended.
 
-[HBv3-series](hbv3-series.md) VMs are optimized for HPC applications such as fluid dynamics, explicit and implicit finite element analysis, weather modeling, seismic processing, reservoir simulation, and RTL simulation. HBv3 VMs feature up to 120 AMD EPYC™ 7003-series (Milan) CPU cores, 448 GB of RAM, and no hyperthreading. HBv3-series VMs also provide 350 GB/sec of memory bandwidth, up to 32 MB of L3 cache per core, up to 7 GB/s of block device SSD performance, and clock frequencies up to 3.5 GHz.

 All HBv3-series VMs feature 200 Gb/sec HDR InfiniBand from NVIDIA Networking to enable supercomputer-scale MPI workloads. These VMs are connected in a non-blocking fat tree for optimized and consistent RDMA performance. The HDR InfiniBand fabric also supports Adaptive Routing and the Dynamic Connected Transport (DCT, in addition to standard RC and UD transports). These features enhance application performance, scalability, and consistency, and their usage is strongly recommended.

 [HC-series](hc-series.md) VMs are optimized for applications driven by dense computation, such as implicit finite element analysis, molecular dynamics, and computational chemistry. HC VMs feature 44 Intel Xeon Platinum 8168 processor cores, 8 GB of RAM per CPU core, and no hyperthreading. The Intel Xeon Platinum platform supports Intel’s rich ecosystem of software tools such as the Intel Math Kernel Library.
 
-[HX-series](hx-series.md) VMs are optimized for workloads that require significant memory capacity with twice the memory capacity as HBv4. For example, workloads such as silicon design can use HX-series VMs to enable EDA customers targeting the most advanced manufacturing processes to run their most memory-intensive workloads. HX VMs feature up to 176 AMD EPYC 9004-series (Genoa) CPU cores, 1408 GB of RAM, and no simultaneous multithreading. HX-series VMs also provide 800 GB/s of DDR5 memory bandwidth and 768 MB L3 cache per VM, up to 12 GB/s (reads) and 7 GB/s (writes) of block device SSD performance, and clock frequencies up to 3.7 GHz.
