Vortex is a full-stack open-source RISC-V GPGPU supporting OpenCL, with configurable cores, warps, and threads, plus graphics and tensor core extensions. It includes a complete software stack (compiler, driver, runtime) and multiple backend drivers including a C++ simulator, RTL simulator, and physical FPGA implementations.

Use cases

• prototype GPU architectures in simulation before FPGA implementation
• run OpenCL workloads on an open-source RISC-V GPGPU
• research GPU microarchitecture with configurable cores and warps
• test graphics rendering pipelines on FPGA
• experiment with tensor cores and structured sparsity
• develop and validate RISC-V ISA extensions for GPGPU

When to choose

• you need an open-source, customizable GPGPU for architecture research
• you want to prototype GPU designs on FPGA or in simulation
• you need OpenCL support on RISC-V hardware
• you're exploring GPU ISA extensions or graphics pipelines

When to avoid

• you need a production GPU with mature driver support
• you require CUDA or proprietary GPU frameworks
• you need high-performance computing beyond FPGA capabilities
• you want a plug-and-play GPU without hardware design involvement
