Imagination GPU for Ventana 4nm RISC-V chiplets
Cette publication existe aussi en Français
Ventana Micro Systems is using GPU cores from Imagination Technologies in the UK for data centre and automotive RISC-V chip designs.
The partnership between Ventana and Imagination is aimed at developers working on data centre, automotive, 5G and AI chips and comes as Ventana launches its second generation Veyron RISC-V CPU core IP and chiplet designs.
The Veyron V2 is the highest performance RISC-V processor available today with a frequency of 3.6GHz on a 4nm process technology and is offered in the form of chiplets and IP.
The 40% improvement in performance comes from a fifteen instruction wide, aggressive out-of-order pipeline in the microarchitecture to achieve the higher frequency with a high performance processor fabric architecture, enhanced cache hierarchy, and the addition of a 512bit vector processor and AI matrix extensions.
There are 32 cores per cluster with 128MBits of shared L3 cache per cluster that can scale to 192 cores. It also includes a server-class IO MMU memory management unit and Advanced Interrupt Architecture (AIA) system IP as well as side channel attack mitigation to protect the chip.
The Veyron V2 chiplet uses the UCIe chiplet interconnect and can accelerate time to market by up to two years and reducing development costs by up to 75%. The V2 will also support open source software from the RISC-V Ecosystem Project (RISE) to quickly deploy open, scalable, and versatile code.

“Veyron V2 represents a leap forward in our quest to lead the industry in high-performance RISC-V CPUs that are ready for rapid customer adoption,” said Balaji Baktha, Founder and CEO of Ventana.
Ventana has Domain Specific Accelerators that are tightly coupled with the Veyron V2 processor pipeline to enhance workload efficiency across the entire data centre infrastructure. This is where the Imagination GPU IP will be integrated into the chiplet or used as a separate chiplet.
The collaboration shows the GPU working efficiently with a RISC-V CPU for client operating systems in markets such as mobile and automotive.
“We are seeing strong customer interest to adopt RISC-V in Client and Automotive applications. Our partnership with Imagination enables us to address these needs with complete platform solutions consisting of best-in-class Veyron CPUs from Ventana and market leading GPUs from Imagination,” said Baktha.
“Imagination’s GPUs are widely recognized for their performance and efficiency in automotive, industrial, and client applications, making them a natural choice for a partnership. Together, we provide new opportunities for innovation and differentiation for our customers across the globe.”
“By integrating Imagination’s deep experience in GPUs with Ventana’s high-performance RISC-V CPUs, we demonstrate our commitment to accelerate RISC-V adoption for customers in the mobile and automotive markets,” said Simon Beresford-Wylie, CEO of Imagination Technologies. “As the defacto GPU IP provider for the RISC-V ecosystem, we are excited to extend this partnership with Ventana.”

Both companies are premier members of RISC-V International and the (RISE) and are committed to driving innovation in the industry through open architecture.
“Though there are over 3,000 member companies involved with the software ecosystem development, this partnership between Ventana and Imagination is a significant step forward for the industry, as it brings together two processor leaders in their respective fields,” said Dr. Jon Peddie of Jon Peddie Resarch. “With their combined expertise in CPUs and GPUs, the two companies are well positioned to drive innovation and accelerate the adoption of the RISC-V open architecture.”
Ventana provides a Software Development Kit (SDK) which includes a comprehensive set of software building blocks already proven on the existing RISC-V platform.
