These standards-based tools deliver choice in hardware and ease in developing high-performance applications that run on multiarchitecture systems.

What’s new in the 2023 oneAPI and AI tools?

Compilers & SYCL support

  • Intel oneAPI DPC++/C++ Compiler improves CPU and GPU offload performance and broadens SYCL language support for improved code portability and productivity.
  • Intel oneAPI DPC++ Library (oneDPL) expands support of the C++ standard library in SYCL kernels with additional heap and sorting algorithms and adds the ability to use OpenMP for thread-level parallelism.
  • Intel DPC++ Compatibility Tool (based on the open-source SYCLomatic project) improves the migration of CUDA library APIs, including those for runtime and drivers, cuBLAS, and cuDNN.
  • Intel Fortran Compiler implements coarrays, eliminating the need for external APIs such as MPI or OpenMP, expands OpenMP 5.x offloading features, adds DO CONCURRENT GPU offload, and improves optimisations for source-level debugging.

Performance libraries in Intel oneAPI Base Toolkit

  • Intel oneAPI Math Kernel Library increases CUDA library function API compatibility coverage for BLAS and FFT; for Sapphire Rapids, leverages Intel XMX to optimize matrix multiply computations for TF32, FP16, BF16, and INT8 data types; and provides interfaces for SYCL and C/Fortran OpenMP offload programming.
  • Intel oneAPI Threading Building Blocks improve support and use of the latest C++ standard for parallel sort, offers an improved synchronization mechanism to reduce contention when multiple task arena calls are used concurrently, and add support for Microsoft Visual Studio 2022 and Windows Server 2022.
  • Intel oneAPI Video Processing Library supports the industry’s only hardware AV1 codec in the Intel Data Center GPU Flex Series and Intel Arc(tm) processors; expands OS support for RHEL9, CentOS, Stream 9, SLES15Sp4, and Rocky 9 Linux; and adds parallel encoding feature to sample multi transcode.

Analysis & Debug

  • Intel VTune Profiler enables the ability to identify MPI imbalance issues via its Application Performance Snapshot feature; delivers visibility into Xe Link cross-card traffic for utilisation, bandwidth consumption, and other issues; and adds support for 4th Gen Intel Xeon Scalable Processors (Sapphire Rapids), Max Series (Ponte Vecchio), and 13th Gen Intel Core processors.
  • Intel Advisor adds automated roofline analysis for Intel Data Center GPU MAX Series to identify and prioritize memory, cache, or compute bottlenecks and understand their causes and delivers actionable recommendations for optimising data-transfer reuse costs of CPU-to-GPU offloading.

AI and Analytics in Intel oneAPI Base Toolkit

  • Intel AI Analytics Toolkit can now be run natively on Windows with full parity to Linux except for distributed training (GPU support is coming in Q1 2023).
  • Intel oneAPI Deep Neural Network Library further supports the delivery of superior CNN performance by enabling advanced features in 4th Gen Intel Xeon Scalable Processors including Intel AMX, AVX-512, VNNI, and bfloat16.
  • Intel Distribution of Modin integrates with new heterogeneous data kernels (HDK) solution in the back end, enabling AI solution scale from low-compute resources to large- or distributed-computed resources.
  • Beta additions for Intel Distribution for Python include the compute-follows-data model extension to GPU, data exchange between libraries and frameworks, and data-parallel extensions for NumPy and Numba packages.

Rendering & Visual Computing

  • Intel oneAPI Rendering Toolkit includes the Intel Implicit SPMD Program Compiler runtime library for fast SIMD performance on CPUs.
  • Intel Open Volume Kernel Library increases memory-layout efficiency for VDB volumes and adds an AVX-512 8-wide CPU device mode for increased workload performance.
  • Intel OSPRay and Intel OSPRay Studio add features for multi-segment deformation motion blur for mesh geometry, primitive, and objects; face-varying attributes for mesh and subdivision geometry; new light capabilities such as photometric light types; and instance ID buffers to create segmentation images for AI training.

Why should you use oneAPI?

With 48% of developers targeting heterogeneous systems that use more than one kind of processor*, more efficient multiarchitecture programming is required to address the increasing scope and scale of real-world workloads.

Using oneAPI’s open, unified programming model with Intel’s standards-based multiarchitecture tools provides freedom of choice in hardware, performance, productivity, and code portability for CPUs and accelerators. Code written for proprietary programming models, like CUDA, lacks portability to other hardware, creating a siloed development practice that locks organisations into a closed ecosystem.

License Options

Single-Node vs Multi-Node

  • Single-Node: supported for use on laptop, notebook, desktop, PC, or workstation
  • Multi-Node: supported for use on laptops, notebooks, desktops, PC, workstations and distributed memory systems ie HPC clusters
    • The applications the developer is writing will determine which option they should purchase

License Types

Named user

  • 10 Workgroup (former 2-seat Concurrent). Support for up to 10 developers
  • 25 Workgroup (former 5-seat Concurrent). Support for up to 250 developers
  • 50 Workgroup. Support for up to 50 developers

With oneAPI Toolkit, the need for a license server has been removed. Users must be compliant with Intel’s EULA and purchase the number of seats to match the number of users who need to use the software concurrently.

  • Academic
    Degree-granting institutions only; colleges and universities that teach students in higher education towards earning a degree
  • Commercial
    All other users, including government and non-profit institutions that are not degree-granting
  • Languages
    No language selection. Intel oneAPI Base & HPC Toolkit includes both Fortran, C++, Data Parallel C++ and Python compilers in the same SKU.
  • Operating Systems
    All supported OS’s will be included in the same SKU – Windows, Linux, macOS. No OS selection.

Network licenses changes with Intel oneAPI Toolkit

Network licenses (concurrent) are still available as 2 and 5 concurrent user licenses, but these are named differently with oneAPI:

  • 10 Workgroup means up to 10 developers can get support. This license type was previously called 2 Concurrent.
  • 25 Workgroup means up to 25 developers can get support. This license type was previously called 5 Concurrent.
  • 50 Workgroup means up to 50 developers can get support.

I.e. for oneAPI, a maximum number of developers is set for the network licenses, who can then be registered in the IRC and are entitled to request Intel technical support in the confidential Intel Online Service Center. FlexLM is no longer included for the network licenses (as was the case with IPSXE). Licensing and usage restrictions now result from the legal basis (i.e. the license agreement – EULA).


Analyzers (ie VTune Profiler and MPI) and libraries will no longer be available as standalone products.

  • New licenses will only be available through the purchase of oneAPI Base or oneAPI Base & HPC Toolkit Single Node or Multi-Node, depending on the product.
  • Upgrade Promotions to oneAPI are available for existing users with active support


All registered users of Intel Parallel Studio and Intel System Studio (ISPXE or ISS) with active support will receive an email from Intel with the option to upgrade to the oneAPI product corresponding to their existing product free of charge.

  • If the user chooses the free upgrade option, their existing legacy product will be retired, and a new serial number will be issued to the same support end date as their legacy product.
  • Once upgraded to oneAPI, users will be eligible for all version updates & upgrades that Intel releases for oneAPI while their support agreement is active.
  • For continued support, eligible users can purchase oneAPI SSR SKUs
  • If the user does not choose to upgrade to oneAPI, the user can continue using their existing product, but they will not receive any new version updates (unless there are security bug fixes)
  • They will only be able to stay on the version they currently own.
  • Users with active support will continue to have the free upgrade link available to them while support for their license remains active. Once support expires, the free upgrade option will go away.
  • Users who have support in the post-expiry renewal range can purchase a post-expiry SSR SKU for their existing product to get their support active. Then, they will receive a link to upgrade to oneAPI for free as part of their service & support agreement.


  • The Upgrade Promo SKU might be a more cost-effective option for existing Composer Edition users to purchase instead of selecting the free oneAPI Upgrade offer, depending on the type of license they own.
  • Users need to be aware that the Upgrade Promotions are ONLY eligible for purchase BEFORE they click the “Upgrade” to oneAPI if they are currently under active support.
  • Once a user upgrades for free, the upgrade promotion goes away.
  • New Update: IPSXE users who have support which has expired less than 6 months can also purchase an oneAPI Upgrade Promotion SKU.
  • With this purchase, a new serial number will be issued with 12 months of support extended from their current support expiration date.

ONEAPI UPGRADE in Intel oneAPI Base Toolkit

  • Upgrade to another suite with additional capabilities, i.e. from oneAPI Base Toolkit to oneAPI Base & HPC Toolkit
  • Upgrade from oneAPI Single-Node to Multi-Node
  • With this purchase, a new serial number will be issued with 12 months of support extended from their current support expiration date.
