# HIP Mandelbrot
GPU Implementation of Mandelbrot Fractal Generator with Benchmarking using [AMD HIP SDK](https://github.com/ROCm-Developer-Tools/HIP).
Computes for the Mandelbrot set in the complex plane bounded by the rectangular corners (-2.0, -2.0) to (2.0, 2.0).
## Usage
```cmd
To use:
[Command Prompt] HIPMandelbrot.exe [WIDTH] [HEIGHT]
or
[Command Prompt] HIPMandelbrot.exe [N]
```
## Sample Run
```cmd
[Command Prompt] HIPMandelbrot.exe 32768 32768
Device: AMD Radeon RX 7800 XT

where:
- **N** - length of the square image's side (in pixels)
- **speed factor** - ratio between CPU and GPU elapsed times (**CPU**/**GPU**)
**Test Machine**
- CPU: Ryzen 5700x (8 core/16 threads)
- 32GB 3200MT/s CL16 DDR4
- Gigabyte B550I AORUS PRO AX rev 1.2
- GPU: Sapphire Pulse 7800xt 16GB GDDR6
