a 586/90

Postby elianda » 2016-5-02 @ 20:26

At the Long Night of Computer Games in Leipzig I met Mike and he told me that he brought a computer for me, it is a surprise...
Then he put a desktop case on the table labelled:

Image

On sunday evening I finally had some time to check it out.

First it was like this:
Image

but then...
Image

a deep breath removed all the dust (just kidding...)
Image

So CPU is a NexGen NX586-P90 at 84 MHz, no FPU. VESA Local Bus Board (at 42 MHz).

The case was in bad shape so I took out the board:
Image

Added some cards:
Image

Some benches / sysinfo tools and failing detections:
3DBench2
Image

3DBench2 Turbo Off
Image

Doom
Image

Quarterdeck Manifest
Image

NSSI failing at CPU speed
Image

NSSI (async Cache is actually 256 kB)
Image

PC Player
Image

Speedsys failing on detection and cache graph
Image

Duke3D runs as well.

Nice, never had a Nexgen system.

Same board as mine. Looks like the owner of that one also had trouble finding those CR2302 batteries (at least, that didn't cost the moon) so they too used an external battery. Anyways, welcome to the club, we should all become elitists and not talk to anyone else. :P

Looking at the heatsink, I swear I have seen that exact board somewhere before, I just don't know where it was.

Either way, should prove to be fun for you, I haven't had a chance to do much with mine yet and probably won't until a case gets freed up, probably later this week.

I really like the early Pentiums. For real Dosgaming they are really good machines!
Because my Cel433 is not ideal for Dosgaming, I currently build a SCENIC-C5 which
is a small and silent Desktop-Machine with a wide CPU-Range between P75-P200.

This is not a Pentium though :)
This is something far cooler!

...on the second view...jeah, not a "normal" pentium (586).
...but what's the deal? is it "only" rare or has it some really cool features?
Did not knew this type of CPU before.

A Pentium is a Pentium. As in, the Intel chip.
You shouldn't call anything else a Pentium. They have different architectures, and therefore different performance characteristics.

Well, 'cool' features... AMD clearly thought so. They bought NexGen, and used the NexGen technology in their K6 chip.

So, it's kind like a K5.5? ;)

Well, the case is standard AT form factor. It has small stereo speakers and about 10 knobs for volume, inputs for MIC and output on the back, most likely for Karaoke stuff. Nothing of this is connected to a sound card or CD-ROM. A few parts of the buttons for On/Off / Turbo / Reset are missing. I am not sure yet if it is worth to keep - it as nothing on it that is specifically 'NexGen'.
I would rather like to put the board in another AT case that is more standard design and suited to put some case fans as well.

K5.5 is misleading as the K5 is a AMD development with an AMD RISC core (29k). The NexGen was an independent development. The AMD K6 is based in the NexGen core. So there is no transition from K5 to K6, it is something different.

The interesting thing about the NexGen is that it has a RISC backend, and translates x86 instructions to native RISC-ops on-the-fly, very similar to what eg a Motorola 68060 or Pentium Pro do (and all x86 since then). I believe it was the first x86 CPU to do so. As far as I know, it did not yet have the capability to reorder instructions and rename registers internally though, like the Pentium Pro did. This was included in the Nx686, which became the K6.

Can you post a photo of the case please? I had one like these in the mid-90s. The speaker and mic connectors at the back are meant to be connected to a sound card via 3.5mm cables. If it's the same I had, I'd probably be interested in it.

Yep, this. Very cool find. I remember the NexGens being promoted in german computer magazines in 94 or 95.

No NPU Socket ? :O

Too bad its not 586 Instruction combatible.
Linux will only run with 386 Instruction Set on this CPU.

That's a really cool motherboard and CPU, always been fascinated by the NextGen stuff. Wish I'd bought one years ago when they were still at least slightly common.

If it's a later model 5x86, the FPU may be integrated in the CPU.

It has no FPU, but it is not really an issue. Quake does not run but performance would be unplayable anyway.
Duke3D runs with IDON and DNRATE shows 14 fps at Start of HH / Let's Rock / No Sound.
Performance in Duke3D is varying a lot, some locations have 70 fps, a few go down to 6 fps.
Same for the 386 build of Duke3D.

Oh wow, that is a very unusual find.

I seem to remember that it was possible to feed RISC instructions directly to the Nexgen and obtain a speedup, but there were so few chips it never really went anywhere.
