I noticed it in the Cyrix Appreciation thread, I hope you can get it to work!

It is [almost] a Cyrix Media GXm CPU, aka Geode from National Semiconductor. According to Wiki, it is nearly identical to the original Cyrix Media GXm CPUs, but with a die shrink, that is, .18 um instead of .35 um. I have the 266 MHz Media GXm CPU in a system now, but would like to maximise the speed to 300 MHz. I am hoping that this GX1 will work in the GXm motherboard. Wiki mentions that the GX1 uses the CS5530A companion chipset, while the GXm uses the CS5530 chipset. I am hoping that the "A" suffix is only related to which onboard graphics and sound is used on the CPU. On my system I have the integrated sound and graphics disabled, so hopefully this 300 MHz GX1 chip will work. If it works, it will be the fastest Cyrix 5x86-based CPU in my collection.
The Geode 300/333 MHz GX1 CPU is not easily found in the PGA form factor, so I feel lucky to have got this little gem for $20 shipped. Luckily, my motherboard also supports these lower voltages.
The purple lettering is also pretty unique.
