I own a Windows 7 tower-computer I name ‘Mithral’, which has an NVIDIA GeForce GTX460 graphics card. That was state-of-the-art around 2011. I read that its GPU was identical to that of the GTX470, except that the GPU was supposed to possess 8 core-groups. In the factory, they tested the GPUs, and if they found that one of the core-groups was defective, they used a laser to deactivate that one, and sold the graphics card for a lower price, as a GTX460. According to the first screen-shot, which was obtained using “GPU-Z”, it has 7 * 48 = 336 cores.
I also own a Linux-based laptop named ‘Klystron’, with a nonspecific AMD / ATI chipset – both CPU and GPU – which was state-of-the-art around 2013. The second and third attachment seem to show that it possesses 6 * 64 = 384 cores. The second screen-shot was obtained using “KInfoCenter”, and the last text-quotation was obtained from the OpenCL toolkit installed on the same laptop.
