AMD vs INTEL DX2-66 for Linux

Post by I.W.Bark » Fri, 08 Jul 1994 20:57:44



Hi.
  I just 'phoned to order a new motherboard and processor for my dead PC
and the salesman reported some problems with AMD processors under Linux.

Since the price difference between Intel and AMD is marginal, but I would
prefer AMD (superior overclocking ability???), what do others think?

Anyone out there using a TMC VLB (PAT-48AV), 256K cache with AMD DX2-66
and 8MB RAM?

Also, is the 70 or 80nS RAM going to cut it with the DX2 or will I need
to introduce memory waitstates?

PS. Where's the faq??

Iain.

Yes.  Early revisions (Do you have any guarantee you won't get one?)
have a floating point bug in them which manifests itself when running
Ghostscript.

Throw a peltier junction on it, and you can probably take a Intel
486DX2-66 to 80Mhz.

Maybe.  Most motherboards are happy with 70, some work with 80, some
are unreliable unless you go with 60s.

There will be _some_ wait states, but weather this is user configurable enough
to get reliable performance with your mainboard remains to get good performance
with a certain speed of RAM remains to be seen.

Personally, I'm running an AMD DX2-66 chip on an EISA-VL system and having
NO problem whatsoever.. saved $125 too.  It runs a little faster than the
intel, and a little cooler.  Sure, try it.

Intel inside means nothing.

I have two machines running AMD DX2-66's w/Linux.  System, X and
ghostscript work fine.  My home system is overclocked to DX2-80 with no
problems whatsoever - I'd recommend a CPU fan, though.  I use 80ns SIMMs
with no problems, also.  Certainly shouldn't give you any problems as a
DX2-66, and probably not with a DX2-80 or DX-40 if you've got both banks
filled (so the motherboard can interleave the memory).  Both systems have L2
cache of 256K - I don't know if more would help or less would hurt, but it
works fine on my system. .   40.14 BogoMIPs on startup w/DX2-80.

Hmm, never heard of this term, what is it?  Same as a DX-2 with the Intel
chips?

It simply means that you've put a DX2-66 into a motherboard that is configured
(either by swapping timing chips or changing its jumpers) to run a DX2-80.  
This means the MB is running at 40MHz.  Just make sure you put a good cooling
fan on it.

It's when you run the chip faster than its rated speed, then spend the
rest of your time wondering if that's why your latest programming effort
won't give the right answer.  ;)

No need for such extreme measures; I've only got a litle fan on
it, and it ran 80 MHz. Ok, I only did this for about 4 hours,
but it didn't hjave any problems. 100 didn't work though.
I think the clock doubling circuitry gives up at this frequency.

The AMD I had was a totally different story. When running for about
4 hours, I got flooded with floating point errors! There was
a warning on the chip to use a fan, which I did, but to no avail.
I prefer Intel inside.
By the way, I'm using 60ns RAM.

1. 486/dx2-66 vs P60 vs P66 vs P90 ?

Does anybody have any benchmark figures on the relative raw CPU
performance of:

        486/dx2-66
        Pentium 60
        Pentium 66
        Pentium 90

I am planning to purchase a system and it seems like the price
difference between the 486/dx2-66 and the P66 is about $300, and about
another $300 difference to get to the P90.  I'm trying to allocate my
$ resources in the best way possible.

I realize that system performance depends on more than just CPU
performance, by the way.
