Older CPU benchmarks, Cyrix MII 300 and AMD K6-2

Donald McTrevor

Anyone know where I can find benchmarks to compare
the two processors.

Particularly the
AMD K6-2: 300 - 333 MHz

to the

Cyrix MII PR300 which may also be known as a
Cyrix 6x86MX/MII 225Mhx PR300

I have tried looking myself but not with much luck.
I am trying to find out if it would be worth replacing the latter
with the former. Would I see a worthwhile perfromance increase or
are they pretty much rated the same?

TIA.
 
Unclear if this is a joke.
The K2 topped out at about 500mHz: that would be the only worthwhile
replacement if you could find one. There was a rare K3 with increased cache
but not many of those were ever made.
It's time to get a new computer . . .

What ten minutes and still no replies!!!
Anyway I will start the ball rolling
Here are some for the K6 (K6 or K6-2???)
http://www6.tomshardware.com/cpu/19980528/k6-2-04.html

Not sure if there is much difference on this one, again I find the name of
the particular CPU involved rather comfusing.
http://www6.tomshardware.com/cpu/19980416/performance-01.html#benchmark_results

I get the impression the performance if pretty similiar ie within 10%
I was hoping for about 50% increase?


Some more 'bumf'

http://www.kingli.com/cpu-compare.htm
Almost what I am looking for but its AMD 266 not 333!!

Other stuff.

Anyway enough!!

Not a joke, *if* I could could get a 50% performance increase for less the
£10 (inc P&P) then I would do it. (About £5 for the CPU.)
I am sure there are plenty of people here who are willing to pay £100+
for a 10%-20% increase on a modern machine.
My mobo won't go above 333Mhz anyway (I think).

A 50% increase *might* enable me to do what I want to do.
(basically play to poker tables *safely* (there is a danger it
might "time-out" on one table, costing me more than £5!!))
Also I would learn a bit by changing CPU.

The alternative is a new PC (~£500) A slightly faster CPU
might be a stop-gap for me to get a 939 pin rather than a 754 pin
AMD 64, the 939 pin model, which I believe would have a
considerably longer life span, as it would, I think, take the duel
core AMD's.

Is this the very rare CPU you meant?
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=15921&item=6789116216&rd=1

Anyway its a K2 not a K3 but as it runs at 333Mhz it might be about 50%
faster thna my Cyrix MII PR300 which runs at 225mhz (or maybe 233mhz).

Its hard to verify that though as I can't find direct comparison benchmarks
and benchmarks can be misleading anyway, it might not be faster in the
right area.

Well how much time should really be spent on getting another
20% out of a really old box that might die from old age at
any time?

Just get a K6/2-400 or don't bother. Your time is better
spend finding something faster though, just about anything
newer is faster so you can simply choose the cheapest
working parts you can find.

You never did mention exactly where you need the performance
increase. These days one will benefit from more memory and
a faster hard drive than that motherboard can even support.

you could build a new box and reuse your monitor for about £250
it wouldnt be cutting edge but it would be new parts and a LOT
faster than what you have - it'd run office apps and internet browsing
just fine.

Everyone has said you would be better getting the cheapest new PC you can
find and I would tend to agree, but if you are looking for minimal spend,
why not look on Ebay for a second hand PC or laptop - anything from the last
few (4 or 5) years will probably be faster. In fact, I doubt very much if
you would be able to find anything slower for sale!

If you search on ebay, choose the Desktop PCs category and search all, then
limit your search to Buy-It-Now and PayPal only systems. Limit the price
range to maybe 20-30 pounds and you get over 50 PC systems for sale - Dells,
Compaqs etc. Make sure you enter minimum £20 or you get all the trawlers
that advertise junk and imaginary services on EBay.

For example - P3 650MHz 128MB, 10GB CD - £25 + £8 delivery:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=3746&item=5224485347&rd=1

There are loads

Yes a laptop is a futher consideration, incuding for a new machine.
I believe that now laptop sales have or are about to outsell
desktop machines. Considering the weight and bulk of a desktop
thats not such a surprise. The small size and portability are a
big plus, although you will lose out somewhat on the spec,

True but it could be a sign that these people already have
desktops and need portability, not that they're choosing one
over the other, or that all else being equal, a laptop won't
last as long so a lower replacement interval translates into
higher sales per market saturation.

Donald I'm not laughing . I have new systems and still kept a few of
my
old ones...I would go with the AMD K6-2 series, a lot will depend on
your
motherboard what gain you get.Hopefully your board supports SD ram
and supports 100Mhz FSB? One thing easy is even if you get a 450mhz
chip and your manual says no , it will still work clocked back a
little.
Click to expand...

I am not sure.
What I can say is that the max 'clock' is 75MHz and the max
clock multiplier is X4, I looked at my jumper settings and I am
on 75MHz X 3 = 225MHz is that 75MHz my FSB? I am a little
unclear about this, but I am pretty sure it is not a 100MHz FSB.
The CPU clocks are listed as 50, 60, 66, & 75.

Again I am a bit confused over RAM too, I will quote from my
mobo manual (which I recently found!!)
"DRAM Type Supports EDO Ram. (both symetrical and
asymmetrical, "(whatever that means?)")"

Also:-
Access time:- 70ns or faster for FPM/EDO or 60ns or faster for SDRAM
(which indicated it does take SDRAM)

However I have only ever used 72 pin EDO RAM 60ns when I upgraded
I am unsure how the 60ns relates to bus speed.
Also the SDRAM I see on ebay seems to be 168 pin DIMMS and
they are not going to fit into my 72 pin slots are they!!!!!

BIOS updates can often fix it anyway , sometimes updating the BIOS
will support the K6-3 series as well....

K6-2 450Mhz I reckon shades a Pentium 2 450 and thats a big
statement

I think 300Mhz is the max my mobo can manage :O(

My first PC had a Cyrix MII 300 CPU - which i upgraded to an AMD K6 300 (not
a K6 -2).
The upgrade definately made my PC a bit more responsive.

Well.... I have just found I have won an auction on Ebay so I will be
getting one
for the princely sum of £0.99!!!
It will be a cheap upgrade!! Assuming I can fit it.

Well I have managed, at long last to find the data myself here are the
links:-

http://www.cpu-world.com/CPUs/K6-2/AMD-K6-2 300 - AMD-K6-2-300AFR.html
http://www.cpu-world.com/CPUs/MII/Cyrix-MII-300GP (75 MHz 2.9V).html
(not sure if it is precisely the correct K6 model.

Here is a comparison of some benchmarks:-

http://www.cpu-world.com/cgi-bin/Co...&CPU4=&PAGE_NAME=COMPARE_BENCH&ACTION=Compare

Which shows some healthy performance increases apart from Sandra Dhrystone
(MIPS)
which is basically the same.however the next lowest increase is a 32%
increase.
However overall I think I should see 50%-100% increase?
Well worth it for the £0.99 the processor costs me!!
