I've been using an AMD AM5x86-P75 for quite some time now with no difficulties. It isn't actually a pentium-class chip. It's a 4x internal clock 486 with a bigger (16k) on-chip cache and support for write-back caching.
It's designed to run at 33MHz external (133MHz internal). I've been overclocking mine to 40MHz external (160MHz internal) with no problems. In order to keep heat problems away I have a heat sink and fan attached (which AMD recommends), and heat sink compound in between.
AMD claims that you get comperable performance to a Pentium-75 at the recommended clock speed. As I don't have a P75 to compare to, I can't comment on that. I do know that it is snappy quick compared to the i486DX33 I was using before.
I am running linux-2.0.27 which detects the chip correctly as: processor : 0 cpu : 486 model : Am5x86-WB vendor_id : AuthenticAMD stepping : 4 fdiv_bug : no hlt_bug : no fpu : yes fpu_exception : yes cpuid : yes wp : yes flags : fpu bogomips : 79.87
Hope that helps, Brett

Does anyone know much about AMD chips?... I am looking arround and found a decent deal on a AMD AM5x86-P75...
Are there any major differences between this and a noormal pentium... will linux like it? more? less? different?
Thanks!
