   Hi all,

I am considering getting a cyrix 150+ 686 motherboard, I'm curious whether
it's been tested with GP2.. Anybody out there with both (GP2 and a cyrix
product) ? Should I take the risk ? I heard there were some
incompatibilities, but the price is right !  TIA ! Greg.

PS: It's no risk to buy other processors than Intel. There are more
people in this world knowing how to create a processor. I use this
system for 2 months now *without* any problems.

Bye

Robert

I am NOT paranoid.  And why are you always watching me?!?

I have been running a cyrix 686-120 for a month or so and haven't had too
many problems. I get freezes under X-windows in Linux, but I can't narrow
that down to the processor as yet.  As for quake, it runs flawlessly,
though not as fast as I would like. I can't really play at any res
above 320x200 without getting lag in the sound.

The FPU performance on the cyrix isn't as good as the P rating that
the CPU claims (ie. a 686-120 does NOT perform like a P5-150 when
it comes to FP performance).

It flies on NFS, though.  If I can just get my paws on F1GP2, I could
test it out, too. I think I'll call SH right now.

I have the 6x86 P150 and it works perfectly (with GP2 too).

here are my details:
System: Windows NT 3.51 & Dos 6.2
Processor type and speed: Cyrix 6X86 P-150 (120 MHz)
RAM: 24 Mb
CACHE:256 Kb PBCache
Video card: Diamond Stealth 64 PCI (3001 ? can't remember exactly)
Video RAM: 1 Mb DRAM

Detail in VGA: absolutely all on
Frame rate in VGA: 21.3

Detail in SVGA: everything else on but sky texture
Frame rate in SVGA: 16 (no good enough, must lose some datails. Get easily
about 20 fps with still lots of details on)

Input controller used: keyboard (old champion I am)

Sound card: SB 16

Any brief comments on set-up:

Cyrix do make nice processors at the moment, but time will tell if there
is no risk. So far I have always gone with compatibility and stuck with
Intel, but the price of Cyrix CPUs makes them attractive just now -
let's see what Intel's forthcoming price cuts do to that.

Since you haven't had any problems, can I assume you don't play
Quake...? :)

Cheers!
John

Robert.

BTW prior to this board/processor I had an intel 90 MHz pentium and can
now run Quake in a higher resolution with equal framerates.

Take care,

Chris

One caveat about Cyrix 6x86 chips: their integer performance is great
for the money, but stay away from them if you do any 3D rendering on
your machine - Cyrix's FPU performance is lousy, and will be a
performance downgrade from just about any Pentium.  If you only play
games on the machine, the Cyrix is a good chip (except for those games
already noted).

Lets keep a little perspective here. No, my 166+ doesnt run FPU
intensive games such as quake as fast as an Intel 166, but that doesnt
mean it runs badly. In fact, it runs great. ( well, the 1280x1024 mode
runs like shit :-) ). There are some that say it wont run some
applications that check for the intel trademark, such as Autocad, but
this also is not true, i run acad 13 no problem. DOS stuff may be
different, i havnt tried.

The bottom line is, Intel has a 10~20% speed advantage in FPU
operations, the cyrix 5~10% faster in everything else, including a
full10% in "normal" graphics apps. You can look at prices and decide
what kind of operation is more important to you. If there are
incompatibilities, im gunna sue microsoft, since the win95 logo is
stamped right on the dang cpu :-)

ps.. If you buy a 6x86 make sure you get a GOOD fan/heatsink, this
puppy runs twice as hot as a regular pentium

The Cyrix isn't 5-10% faster in "everything" else, it executes certain
non-FPU instructions faster than a Pentium, and certain ones slower.
Whether it is faster or slower depends upon exactly what you are doing.

There's no doubt though that at the price/performance point the chips
slot into, they are VERY attractive at the moment. Let's see what Intel
does about that on August 1st....

I may have my first Cyrix on Aug 2nd! :)

Cheers!
John
