You type your GPU and the clocks you want to try, and it estimates the gain and the power draw. There's also a window that checks CPU + GPU for PCIe loss and bottleneck %.</p> <h2> What it does </h2> <ul> <li>Estimates memory bandwidth and TFLOPS, stock vs OC</li> <li>Estimates extra power draw and PSU load</li> <li>Offline list of 259 GPUs</li> <li>CPU + GPU compatibility check: PCIe link and bottleneck % at 720p to 4K</li> <li>10 themes</li> </ul> <h2> Honest limits </h2> <p>Everything is an estimate, not a benchmark. It's a beta, and some GPU entries are marked UNVERIFIED.</p> <h2> Download and source </h2> <p><a href="https://github.com/Xtrizer/G-OC-calculator-tool-for-windows-/releases/tag/v2.0.2-beta4" rel="noopener noreferrer">https://github.com/Xtrizer/G-OC-calculator-tool-for-windows-/releases/tag/v2.0.2-beta4</a></p> <p>It's free, MIT license, Windows only. I'm one person making this, so if a number looks wrong for your card, tell me the card and the numbers and I'll fix it<br> i wish you like it!</p> <p><a
