Hold up..are you confusing GPUs with graphics cards? Because I wasn’t aware PC Partner (or it’s brands like Zotac) was in the business of making GPUs. I thought they were in the business of making add-in cards featuring Nvidia GPUs. Unless they make GPUs for industrial applications (which I could find no evidence of), it seems like you’ve conflated the two related but distinct things. I’m a little troubled that a tech journo for Tom’s Hardware doesn’t know the difference between a GPU and a graphics card. For standalone GPUs, the second largest GPU maker is AMD, preceded by Nvidia, with Intel coming in a distant third. (If you include APUs with integrated GPUs in the figures, Intel actually has over two thirds the GPU market, followed by AMD, then NVidia, so AMD is the second-largest GPU maker no matter how you slice it). In any case, I expect someone with a full time job writing about the subject to understand their subject and be precise in their language. That may be too much to expect these days, perhaps.
