AMD k6 233 MMX or NOT
I have an AMD K6 233MHz processor I trying to find out if this chip has MMX capability. The chip doesn't say MMX on it as I've seen on some chips. Any brainyacks out there know your AMD stuff.
I'm sure the 233s were MMX. As far as I know, all K6-2 class AMD cpu's were MMX. They don't have that printed on them...it may say something about two different voltages, like 2.2 volts and 3.3 volts. If so, the 2.2 is the core voltage and the 3.3 volts is for the MMX part.
I'm looking at a spare K6- 2 500 and it is MMX. It does not say MMX, but gives the voltages as 2.2 V CORE / 3.3 volts I/O
Thats the thing it doesn't say K6-2 just K6 with a 3.2 core voltage and 3.3 I/O voltage.
Other markings include 233 ANR, C 9747EJBW
You have an early K-6 chip and the K-6 has the industry-standard multimedia instruction set (MMX). It does not have the same (MMX) that the newer AMD K6-2 chips have-Called "3DNow". The AMD K6-2 3D Now chip contains more graphics and sound instructions than the older K-6.
3.2v core voltage
3.3v I/O voltage
So what your saying, it does have MMX just not the newer K6-2 version. Does anyone have a link with a comparison of the two chips K6 and K6-2?
BobPar, are you sure your K6 dosn't have the -2 somewhere?...I have one of those in my test bed and am about to pull it just for a look see.
This 500 has the following on the case:
AMD-K6-2 / 500AFX
2.2V CORE / 3.3V I/O
Yours only has K6? I was under the impression that after the 200s, they were all K6-2 and were all MMX.
Maybe I have learned something here tonight.
I learned something new too, using the AMD K6 233 when I go into control panel, system properties under the general tab it says: AMD K6™ w/ multimedia extensions. Never noticed that before! On my AMD K6-2 350 it says AMD K6™ 3D processor. I also have a K6-3 400 that says AMD K6™ 3D+ processor.
I also have another AMD K6 300 MHz with just K6 no where does it say -2 /2 or anything, but under general tab it has the same info AMD K6™ w/ multimedia extensions.
Thank you Kurylo

If you Don't know for sure get SiSoft Sandra 2001te Standard (free) and check under the CPU part, it will tell u.
There's a little LowLife in all of us
The K6 does have MMX instructions. I checked out AMD's site.
The reason that the K6 advertises MMX and the K6-2 doesn't is because when the K6 was out, MMX was a new thing that AMD was using to compete with Intel, who also had MMX. Then, when the K6-2 and the Pentium2 came out, MMX was standard and expected of all new chips, so they couldn't use MMX as a selling point then. The 3D part of the K6-2 refers to AMD's 3DNOW instruction set, which was only in AMD's chips.
Thanks for all the good stuff. Didn't think to give SiSoft Sandra a try, I will do that maybe this weekend.
Also, I found a nice site on processors check it out:
The k6-2's appeared first after the 266 (or was it 300) mhz k6, I remember this because I once thought of buying a 266mhz k6, but decided not to when i realized the k6-2 would be out in a couple of months...
Men folket pa sysopt...ar ni verkligen sa pass intresserade av min signatur att ni maste fraga?
Go to this link and look at the bottom of the page.there you can download Wcpuid.exe
it tells you everything about the processor.
