It feels like these days everyone is out to scam you, even social media giants want some of the action. But what about the hardware inside your PC? You might think it's hard to fake a CPU or graphics card, but it is possible and it does happen.
It's not like they're made of cardboard or anything. The GPUs are genuine, they're just older chips that have been relabelled. While it's unlikely your card is dodgy if you bought it somewhere reputable, it doesn't hurt to have peace of mind, especially if you don't think your shiny new GPU is performing as it should.
The latest version of TechPowerUp's GPU-Z, a tool designed to show in-depth information about video cards, now comes with a fake detection feature. All you need to do is download and run it.
GPU-Z will inspect the card's BIOS to make sure it hasn't been tampered with — in this case, to make the card report itself as a model more powerful (and expensive) than it is. If the card is a fake, you'll see "[FAKE]" before the model name, as well as a yellow warning icon.
Here is the full changelog for GPU-Z, including the older GPUs that are being relabelled:
