## What it is
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

## Facets
- artifact type: framework
- maturity: active
- function: simulation, graphics, machine-learning, compiler, sdk
- domain: hardware, gpu-computing
- platform: cross-platform
- tags: gpgpu, risc-v, opencl, fpga, verilog, open-source-hardware, simulator, rtl, gpu-architecture, research, computer-graphics, linux
