WebGPUStress

What it does

WebGPUStress is a browser-based GPU stress test tool that helps you check performance stability, thermal throttling, and FPS consistency — no installation required. Run a quick test online, monitor live metrics, and validate your GPU after overclocking, driver updates, or hardware changes.

Stress test your GPU in the browser with a WebGL workload. Check overclock stability, thermal load, FPS drops, and browser benchmark results with no install.

Push your GPU with a sustained WebGL workload. Use it after an overclock, before a long gaming session, or when a laptop starts fast and slows down after heat builds. No download, no plugin, no executable. Keep browser, driver, and power mode fixed if you compare scores. If FPS and pacing stay consistent through the run, the GPU handled this workload without obvious performance collapse. A real drop over time often points to heat saturation or a power limit. Check cooling, fan behavior, and power mode. This is a browser test. Tab focus, WebGL implementation, and browser throttling can change the result. For final validation, plug in laptops, disable power saving, close background apps, and…from webgpustress.com

  ChartGPU – WebGPU-powered charting library (1M points at 60fps)Jan 2026 · github.com · ▲670

  Creator here. I built ChartGPU because I kept hitting the same wall: charting libraries that claim to be "fast" but choke past 100K data points. The core insight: Canvas2D is fundamentally CPU-bound. Even WebGL chart libraries still do most computation on the CPU. So I moved everything to the GPU via WebGPU: - LTTB downsampling runs as a compute shader - Hit-testing for tooltips/hover is GPU-accelerated - Rendering uses instanced draws (one draw call per series) The result: 1M points at 60fps with smooth zoom/pan. Live demo:…

  PantheonGPU – GPU health testing and AI workload benchmarkingAug 2026 · pantheongpu.com · ▲13

  Hi HN, I built PantheonGPU because I wanted a better way to answer a simple question: is this GPU actually healthy and performing the way it should? A GPU can show normal temperatures and utilization and still be underperforming, unstable under certain workloads, or have memory, PCIe, or configuration issues. PantheonGPU actively tests the GPU instead of only monitoring telemetry. It currently includes 45+ tests covering compute, tensor workloads, memory, cache, PCIe, thermals, stability, and AI/LLM inference. It supports both NVIDIA CUDA and AMD ROCm. I’m also exploring a larger use…

  Utilyze – an open source GPU monitoring tool more accurate than nvtopApr 2026 · systalyze.com · ▲128

  The standard GPU utilization metric reported by nvidia-smi, nvtop, Weights & Biases, Amazon CloudWatch, Google Cloud Monitoring, and Azure Monitor is highly misleading. It reports the fraction of time that any kernel is running on the GPU, which means a GPU can report 100% utilization even if only a small portion of its compute capacity is actually being used. In practice, we've seen workloads with ~1–10% real compute throughput while dashboards show 100%. This becomes a problem when teams rely on that metric for capacity planning or optimization decisions, it can make underutilized systems…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
