Have you had any success over clocking the AMD 5x86-p75-133 ADZ over the AMD-p75-133-ADW ?
I have been able to over clock the “ADW” to 160mhz fine.

How high have you been able to over lock the “ADZ” variant ?

Wikipedia posts that the “ADZ” variant is better suited for over clocking because it can endure higher temps.

But I have not read about anyone going over 160mhz ?

Look here:
486 max

Interesting sidenote: According to CPU-Z, my setup is very close to the infamous IDT WinChip C6 200Mhz. So it's really a 486 class CPU on steroids.

P.S.
Now try to beat my scores =P

I think you were holding the record with quake on a 486 setup... until today 😀. I managed to get 20.3 fps out of my 486 setup today at quake. took me a while to find the right setup for that, but finally managed.

Great!
Did You use quake from philscomputerlab dosbench pack?
Can You show Your BIOS settings, RAM and cache type and speedsys plots?
And what is score in Doom?

Good work.

I never understood if results with overclocked Pentium Overdrive are allowed in this thread (why not if Cyrix 5x86 apparently are?).

Surely that would blow overclocked 5x86 out of water. At least in Quake (not so much in Doom and other tests).

My PODP83 @ 100 MHz with 1MB L2 cache gets close to 25fps.

I even booted to DOS @125 MHz, but it wouldn't complete any benchmarks.

yeah, accepted! 😉
And I improved my values right now to 20.7 fps at quake.

yeah, with a podp83. not with a 486 cpu.

Yes. Those overclocked X5 results are commendable, but against P24T it is uphill battle. No matter if you get the AMD to 200 MHz or not.

The 486 core simply can't compete.
For me a 486 is a "Doom machine" and Quake feels a bit wrong / wonky on it.

and Quake feels a bit wrong / wonky on it.

You didn't played it on P60, huehuehue.

true, but we are talking here about the fastest 486 cpu and not pentium!

Well, the thread has been kicked-off with Cyrix 5x86-133GP as quest for a world's best 486 PCI system.

Thing is if you only consider purest 486 ALU designs (80486 family CPUs), it would be just AMD X5 5x86 overclocking competition as it is the only fast CPU without any 5th generation features.

And you would also add ambiguity as some people, for more or less good reasons, consider IDT C6 or even Cyrix MediaGX or other single-issue CPUs to be 486's (read earlier in this thread)

IMHO whatever vintage goes to 486 socket should be considered if you search for world fastest 486. P24, P24T P24D, Cx 5x86, IBM 5x86C, Am5x86, overdrives, upgrade chips, ...

Just like in 386 competition, you would allow Intel/AMD 386 as well as Super 386, 486SLC/DLC, Blue Lighting and you would compare Pentium with some of its challengers that feature 6th get features.

it would be just AMD X5 5x86 overclocking competition

Not sure how's that a problem. In all practicality, that's the fastest available option for most users. You can buy a bunch of these and filter the one with best OC potential. Heck, maybe even try Intel 486DX4 WB potential under zero Celcius.

The P60 was my introductory machine in regards to Quake - pretty slow but relative to the clockspeed it was great.
If the Intel LX board I ordered works I'll give Quake another run.

A well tuned P60 can run Quake at ~19fps which is faster than most 486 (except for 486 record holders above).

20fps was luxury framerate for games in early 90s.

I agree that framerate expectations were lower in the 90s .

That said, Quake was released in mid 1996 , around the same time as the Pentium 200MHz . The much faster Pentium 133MHz had been on the market for a year already . Granted, neither of those was cheap, but by 1996, a 3 year old Pentium 60MHz was looking pretty outdated with its low clock speeds and and slow chipsets that were not doing it any favors .

For reference, I purchased a Pentium 150MHz in early 1997 while I was student making barely more than minimum wage, so I was definitely not rich, but even I could afford it .

EDIT: I meant no disrespect to those who, for whatever reason, could not afford one at the time. My point is that by Quake's release, the target audience had access to reasonably affordable options well above a Pentium 60.

Well tuned P60 won't provide 19 fps in Quake, from gameplay perspective. Firstly because we bench this stuff without sound and secondly because timedemo 1 is not the worst case scenario. Something like Ziggurat Vertigo on Nightmare difficulty is much harsher on 1993 hardware. You can easily divide timedemo 1 average frame rate by 2 in complex scenarios.

P133 is bare minimum to play software Quake with acceptable performance.

I had a PMMX166 in 1997 but got to see QTest in early 96 on my P60 which ran it pretty well(excluding LAN play).
Most I knew back then weren't " enthusiasts" and thus many still had a DX4/DX5 as their home PC... given they even had one. Maybe it was different in the US.
