Centaur may have disappeared for good, but remnants of the company's products remain if you look hard enough. Computer enthusiast Albert Thomas (aka Bizude) got his hands on Centaur's CHA chip and put it through its paces in various modern triple-A titles.

The CHA processor has a die size of 194 mm² and features eight CNS x86 cores without simultaneous multithreading (SMT). Depending on the bin, the clock speed varies between 2.2 GHz and 2.5 GHz. The 16nm chip has 16MB of L3 cache, supporting AVX-512 instructions and quad-channel DDR4 memory. It even has an onboard AI co-processor, which Centaur had baptized as the NCore. The company had envisioned the CHA processor for the server market, which is why the chip has the NCore accelerator with machine learning capabilities.

    CyrixInstead (Remember the 6x86?)
    TransmetaCPU (Remember the Crusoe?)
    NexGenDriven (Remember the Nx586?)
    RiseRiseRise (Remember the... uh... mP6? Ok, probably not)

    AMD used to hide fun stuff in their CPUID registers. Early K5 era chips had AMDisbetter! and they snuck this one in during the Piledriver generation.

    "Specific to AMD K7 and K8 CPUs, this returns the string "IT'S HAMMER TIME" in EAX, EBX, ECX and EDX, a reference to the MC Hammer song U Can't Touch This. "
