Thought I would play with my WinChip 200 a little, here are some benchmarks compared with a Pentium 200 MMX.
System setup: Abit TX-5, Stealth 2000 pro, Orchid 3Dfx Voodoo. DOS/Win95

DOS Quake fps____| 320x200 | 512x384 | 640 x 480 |GLQuake 640 x 480 |
Winchip 200_________28.3_____14.7______10.8________26.6
Pentium 200 MMX ____46.7_____21.7______15.3________28.5

MDK_____________ DOS w/ Virge | Win95 D3D w/ Voodoo
Winchip 200__________59____________175
Pentium 200 MMX______97___________ 176

Turok __________Voodoo @ 640 x 480 w/ 3Dfx driver
Winchip 200__________25.6 fps
Pentium 200 MMX_____32.3 fps

Gaming with the Winchip in software, is pretty pathetic compared to the Pentium. The Voodoo numbers are much more forgiving. Yes, 3Dfx Voodoo Graphics is that awesome. 😁

Nice chip!

I'd like to have one 😁

Could you perhaps run SuperPi on your winchip system?

Sure thing, but which you want me to run. I'm new to this program, how bout the 1M test?

The 1M test is what I always use, it would be perfect 😀

1M took 23 min. 2 sec. with the WinChip 200.
I'll have to try my P200 when I swap the chips back out.

OMG!!! Bushwack have you become a WinChip semi-aficionado like me? 😁 I only have a WinChip 2 in the collection tho. No C6 or any of the newer ones.

The Winchip CPUs are interesting for a few reasons. First, they were extremely cheap. They were also really compatible chips and even work in Socket 5, I believe. And they run very cool, not much warmer than a 486, although that's because they are rather simple chips not much different than a 486. They relied on SIMD MMX (3dNow in Winchip2) to make them perform a bit better, which really is similar to the plan for the P4 but you don't have P4 heat.

Little tidbit is that the VIA C3/C5/C7 are actually WinChip-derived. VIA bought Cyrix but discovered that the company was a mess of incompetence and bad attitudes and so dissolved it. Then they bought Centaur to build their CPUs but kept the Cyrix chip name.

I have 2 of these 200s, got them at different times but they are both the same. Actually have had them a 2-3 years, just now getting them out to play woth, 🤣.

I have a pretty fair Socket 7 CPU collection, these are my rarest (not saying much), and I have several Cyrix and AMDs and a mess load of Pentiums. I'd like to get a hold of a Rise chip, but you know how cheap and easy those are to get.

Anyone happen to know if a Cyrix MediaGX will work in a regular Socket 7 board?

Retro enthusiasm is a fickle thing so you just never know what you're gonna want to tweak next. 😉

Lately I've been regretting dumping all of my VLB stuff, but I also know in the back of my mind that I got rid of it because I couldn't stand dealing with its flakiness and slowness anymore. Doesn't stop the mind from wandering though.... 🤣

Nope, it won't. They are wired differently because of all the onchip stuff that CPU has

Overclock is a no go with this thing. It happen to post at 225mhz, but gave errors when trying to load Windows. The Abit is a great tweaker board with Pentiums I know, but when it came to the WinChip, BIOS options suddenly became limited. The .5 multiplier option went away and so did voltage adjustments.

Could maybe be fixed with a later BIOS, the one I'm running is a 1997 rev. When I first got the abit board, I put a 97' BIOS on it, the 98' that was on it was just to new for me. 🤣

(Apology to bushwack, because my post below isn't about the Winchip topic.)

I also have this thought. But I keep thinking, what is the best retro gaming equipment to have? IMHO, one way to answer this is to look at your games collection. For instance, if the DOS VGA games "Dark Forces" or "Doom" run without any issues on any Pentium I or II or III mobo, then there's no compelling reason to run it on a 486. I understand that a good 486 VLB board is better than a good 486 PCI board. When I use the word better, I presume that means faster. I'm not sure if there are any other noteable benefits when playing old DOS games. If there are, please tell me. Running the VESA benchmark utility "Pcpbench.exe" on a good 486 VLB board will yield faster results than probably any 486 PCI board, no matter how good the PCI video card is. But I understand that the speed increase is just a couple of frames per second faster. Eg VLB = 9, PCI = 7. (Very approximate values for 100Mhz - I think.) The problem for me is that I wouldn't want to run any DOS VESA game on any 486 mobo. AFAIK, there are no DOS VESA games in existence that won't run flawlessly on any Pentium 1 mobo. So, why choose a VLB based 486 mobo instead of a PCI based 486 mobo? Is there something "special" about a good *VLB* 486 mobo, that gets "lost" when you upgrade from a 486 era mobo to a Pentium era mobo? I ran the "Superscape 3Dbench 1.0" VGA benchmark utility on a PCI 486, with just a DX2-66 CPU in it and got 50 frames per second, and that makes me think - isn't that good enough?

Personally speaking, I've gone about the retro hardware choice the following way -

I've got no PC games from the early 80s up to the late 80s. If I had, I think I'd get a 286 for the early stuff and a 386 for the later stuff. However, the DOSBox emulator is incredible, and IMHO can be considered as a perfectly satisfactory way of playing nearly all ancient DOS games.

I've got a small number of PC games from the early 90s. These games were typically released on 3.5" floppy disk. I think there's 5 ways you can approach this situation. These 5 options are not listed in any special order.

1) Run them on a 386. This was how most of these games were meant to be played. (I don't own any 386 mobos.)

2) Run them on a 486. A small number of these early 90s era games won't work correctly. Typically, you'll get speed problems. If this occurs, you can disable the BIOS cache options. This will eliminate the speed problems at the hardware level, but I don't fully understand if this technique might somehow interfer with any of the games' general gameplay in any way.

3) Use DOSBox.

4) Play the Amiga game equivalent, either on an Amiga or an Amiga emulator. If the same old PC game exists on the Amiga, the chances are it will look better.

5) If the game isn't speed sensitive, then run them on any old Pentium machine.

The other PC games I have are from the early 90s and onwards. These games were typically released on CD-ROM. AFAIK, none of these games have any speed or compatibility problems if you run them on any 486 or old Pentium 1 mobo. In other words, you don't specifically need a 386 to solve any speed problems. So, where does that leave the dilemma about choosing a VLB 486 mobo instead of a PCI 486 mobo? If you own a 386, and any 486, and any old Pentium mobo, I can't see how you would specifically need one. Please correct me if I'm wrong.

Just one other thing - writing the above got me thinking about old socket 7 Pentiums. IMHO, they're quite a useful addition to the retro hardware collection. The good thing is, unlike 386 mobos and to a lesser extent 486 mobos, inexpensive socket 7 mobos + CPUs + RAM can still be easily found.

I was thinking about the speed comparison of a 486 and a 386. When I was testing undocumented jumper setting for a couple of my 486 motherboards, all were capable of running a 20Mhz fsb. Wouldn't that compare to a fast 386 speed wise?

My guess and it is only a guess, is that it would not compare to the "slowness" of a fast 386. It would be faster than any 386.

I tested an Intel SX-25 CPU (not SL enchanced and no writeback) in a PCI board, with its BIOS settings set to "normal", and I got a Superscape 3Dbench 1.0 benchmark score of 20.4. That's quite fast. Also, Speedsys scored 9.12. If you decreased the FSB to 20Mhz, then my guess is that you could theoretically remove approximately 1/5th from these scores. But I think they would still be higher than scores obtained on a fast 386.

(Sorry bushwack, I should have started my ramblings in another post. I hope you don't mind too much.)

Talking about 386 mobos got me searching on ebay. I looked for 386 mainboard, and this thing popped up. (Item 330399153438). You certainly get value for money when it comes to the number of chips. There's not much space left on that board!

Looks like a daunting challenge to fit this in a computer case 😜
I remember having seen lots of these motherboards back when I was an active dumpsterdiver many moons ago. Only item I still have left is a 286 motherboard, it reminds me a lot of the 386 board you posted.
Dunno if that 286 board's still in working condition, I remember having pulled the CPU from it long ago but should still have it laying around somewhere.

Edit: I've tossed most of my VLB and 386 motherboards long ago also. Most had leaked battery residue anyway though. I'm still wanting to build atleast ONE VLB computer but, even though I have a couple VLB cards, none of it is realy any good. iirc I only have those super duper great Tseng cards and a couple Cirrus Logic. I reckon my best ISA graphics card is better then the best VLB graphics card I have. The ISA card is a Diamond Speedstar with 2MB memory but it's kinda reserved for my sole 386 which I also plan on building

Luckily I didn't get into computers until the Pentiums hit the market, I don't have to worry about leaky batteries and the VLB bus. 🤣

Sure I wanted those 088s, on up to the 486, but I just didn't have the funds. I played consoles up until Jan. 1996, and never went back.

Yeah I'm pretty sure you have to have used flaky VLB boards during their heyday to be able to appreciate and yearn for them 🤣. It was very exciting to have a new ultra fast bus to play with back then. But VLB was not such a great design at all really and the boards were usually low quality el cheapo builds on top of it.

I set up my Winchip 2 last night, inspired by you Bushwack. Put that baby on my ASUS P5A running 83x3 (250MHz) with 128MB 2-2-2 SDRAM. If only it had more than just integer multis. Dropped in a Voodoo3 2000 AGP. Installed Quake 2 and the AMD 3DNow patch and let her rip. And it runs pretty well! The 3DNow patch was written by AMD so it's probably the poster boy of 3DNow optimization (I don't know of anything else that took it as seriously).

What's funny is that it appears to run roughly the same frame rate regardless of resolution (up to 1600x1200) because the CPU is such a bottleneck (but it is completely playable and usually quite smooth). I need to run some timedemos but I'd guess it runs 10-40 fps. It slows down quite a bit if there is a lot of visible geometry or a lot of action. You can really feel the Quake 2 engine's geometry culling when some doors open or close. 😁

Oh I found the datasheet PDFs for the Winchip and Winchip2. Lots of info that I hadn't seen before.
