Features
Intel Data Center GPU Flex Series is a flexible, robust, and the industry's most open GPU solution for the intelligent visual cloud. The GPUs support a diverse range of workloads in the industry starting with media streaming and cloud gaming, followed by support for AI visual inference and virtual desktop Infrastructure workloads. It supports an open, standards-based software stack optimized for density and quality with critical server capabilities for high reliability, availability, and scalability. This helps reduce the need for data centers to use disparate solutions and manage heterogenous or proprietary environments.
The ThinkSystem Intel Flex 170 16GB Gen4 Passive GPU offers the following features:
- Open Architecture
The Intel Flex Series GPU supports an open, flexible, standards-based software stack together with oneAPI so developers can build high-performance, cross-architecture applications and solutions. This helps organizations reduce the complexity, cost, and time requirements to bring new solutions to market, enabling engineers and programmers to innovate instead of maintaining code.
- Built-In AV1 Encode
Services built on the royalty-free open-source AV1 codec mean lowering operational expenses while providing higher video quality. Advanced video coding (AVC), High Efficiency Video Coding (HEVC), and VP9 support also comes standard with the Intel Data Center GPU.
- No Licensing Fees
Intel provides free virtual GPU software license to customers for lowering their total cost of ownership in VDI deployments. Furthermore, this can act as a catalyst to accelerate the GPU adoption rate in VDI deployments where graphics & encode accelerations are desired/preferred but can often be cost prohibitive.
- Flexible vGPU Management
The Intel Data Center GPU Flex Series supports multiple vGPU configuration & scheduling options for VDI solutions to meet different customer workload and QoS requirements—such as Linux KVM open-source virtualization technology and VMware ESXi. It also supports both VMware Horizon and Citrix DaaS† on top. The Flex Series accelerators have strong ecosystem support. The top two industry leading desktop & application virtualization solutions, VMware Horizon and Citrix DaaS, will be supported.
- High Performance Virtual Desktop
The Intel Data Center GPU Flex 170 is ideal for VDI deployment targeting power users persona – 3D and media content creation workloads whose graphics and compute performance requirements are high.

Software stack
The Flex Series GPU supports an open, flexible, standards-based software stack with oneAPI cross-architecture programming. The stack includes open source components and libraries, tools and frameworks so developers can create high-performance, cross-architecture media applications and solutions to meet a wide range of use cases. This open approach removes the barriers to proprietary models where code portability and the ability to adopt new architectures across multiple vendors is limited.
Intel enables the software ecosystem through industry collaborations, initiatives and standards bodies. It also provides ongoing leadership, investment and technical contributions to the open source community.
The common set of software capabilities integrates into popular middleware and frameworks, and the stack is delivered in validated productized containers or reference stacks. The containers can be orchestrated with Kubernetes on bare metal or in VMs using SR-IOV virtualization with tools to assign and manage workloads. The toolset is designed to speed time-to-market and enable flexible deployment of multiple workloads on the same GPU.
