Intel has released its Q1 2026 workstation graphics driver, version 32.0.101.8515 WHQL, and the update brings official support for the new Arc Pro B70 and B65 discrete GPUs while also extending support to built-in Arc Pro B390 and B370 graphics in select Core Ultra Series 3 processors, which places these new GPUs into Intel’s certified driver track from day one and ensures better stability for professional workloads.
The company also focuses on professional software support with this release, especially for the Arc Pro B70, which now carries certifications for tools like Ansys Mechanical 2025 R2 and 2026 R1, multiple Ansys 2027 R1 applications, Nemetschek Vectorworks versions from 2024 to 2026, and PTC Creo 11 and 12, and Intel confirms that more ISV certifications are still in progress, which means support will expand further over time.
Performance and Memory Improvements
Intel reports performance gains in SPECviewperf 15 at 1080p compared to its Q4 2025 driver, with improvements of up to 5 percent in creo-04, 4 percent in enscape-01, 7 percent in snx-05, and a notable 32 percent in solidworks-08, and these gains apply to the Arc Pro B-series lineup overall rather than a single GPU.
The update also improves memory handling on built-in Arc Pro GPUs, where systems with 64 GB RAM can allocate up to 93 percent of memory dynamically to the GPU, which helps in heavy workloads such as simulation and 3D rendering.
Highlights of this Workstation Driver
- Support for New built-in Intel® Arc™ Pro B390 and Intel® Arc™ Pro B370 GPUs in select Intel® Core™ Ultra Series 3 Processors.
- Support for New Intel® Arc™ Pro B70, and Intel® Arc™ Pro B65 Discrete GPUs.
- Built-in Intel® Arc™ Pro GPUs in select Intel® Core™ Ultra Processors (series 3, 2 & 1) will support variable increased graphics memory allocations in Microsoft Windows* 10 and Windows* 11 host systems. For example, a 64 GB host system can have up to 93% or 59.5 GB (64 x 0.93=59.5) working memory dynamically allocated to the Built-In Intel® Arc™ Pro GPU.
- Performance improvements on Intel® Arc™ Pro Graphics Products versus Intel® Q4, 2025 software driver for: SPECviewperf* 15 benchmark at 1080p, which include average score increases in:
- creo-04:
Up to 5% increase on Intel® Arc™ Pro B-series GPUs- enscape-01:
Up to 4% increase on Intel® Arc™ Pro B-series GPUs- snx-05:
Up to 7% increase on Intel® Arc™ Pro B-series GPUs
Up to 8% increase on Intel® Arc™ Pro A-series GPUs- solidworks-08:
Up to 32% increase on Intel® Arc™ Pro B-series GPUs
Intel has not confirmed support in its standard Arc driver yet, but based on past releases, that support should follow, while the current update already positions the Arc Pro B70 and B65 for professional use with certified software and improved performance.
