Vortex: OpenCL Compatible RISC-V GPGPU

Re:Vortex: OpenCL Compatible RISC-V GPGPU by MeteOzturk on Thursday March 05, 2020 @06:01PM (#22499303)

I am curious how RISC-V GPGPU development would affect Nvidia’s support for the platform. So far they seemed to be supportive. They’ve contributed NVDLA. They’re a member of the foundation. It’s not far-fetched to think a Jetson with high performance RISC cores is already in development. I hope they won’t back out if they deem a strong edge platform competitor is not in their best interest.

nVidia are not using RISC-V for their "high-performance" GPGPU cores. Their interest in RISC-V is only for support cores, so GPGPU support is neither here nor there.

What Nvidia brings to the table with both the Jetson line and the Tegra line is precisely those GPGPU's. The ARM parts are pretty standard I believe. What I meant was if there was enough interest and development around an open-source architecture for GPGPU's and Neural processing it would have the potential to become a competitor to Nvidia's offering. I am confident it would take years to become a worthy competitor in the desktop and server markets. Edge and portable devices I am not so sure.

Not sure exactly what you're saying here, but NVIDIA's cores are bottom-up custom, and they are very unusual.

The older Jetson units featured standard Cortex-A57 processors and the newer units have their custom processors (Denver and Carmel architectures)
