In order to help my production on SoB 1T race. I started building/finishing/upgrading computers based on the Socket 7 motherboards I had laying around.
Well I just endulged in over $300 to get these sub 500MHz computers going. But I just pulled an AMD 333MHz cpu out for one of the systems and replaced it with a 450MHz AMD K6-2 450MHz OC'ed to 550Mhz (good chip, not many could do that 🙂). I expected to see some better cEMs/sec. Well I did see that increase. It went from 10700cEMs/sec to a stomping 13200cEMs/sec on the same test. After it completed that block and got a new one with a higher n number it went up a little more to 13560cEMs/sec.
Now I look at that old PII 233MHz computer that is less than half the speed of the freshly upgraded 550MHz computer, and it puts out on a average 26900cEMs/sec. Twice as much as AMD's claimed faster than PII's of higher MHz 😛

Ahh well. Here shortly in the next couple days I will have that celeron 4 1.7GHz computer finished as I just got the memory in 😀. Maybe I will start breaking 500cEM/sec per day average.
Unless any of you all know of something that can help the AMD CPU's out. I would recommend Intel chips for this program as I can plainly see AMD=slow, Intel=fast... at least for the older ones. Somebody out there with a Althlon XP care posting your numbers?

Just had to get that rant out of my system. I am unhappy with the outcome of that spending/performace ratio. Now I feel better :frown:

The old AMD chips were not much good at any project when compared to later generation chips.
Your P2 does better because it is a newer generation than your AMD. So you are comparing apples to oranges.
Even at half the clockspeed it does twice the amount of work. It has a 512 K cache and a much better FPU, among other advances.
I'm sure that you would see a great increase with the latest batch of AMD chips, their FPU is now better than iNtel's and they quite seriously kick butt.
 
Well I looked in a 97 and 98 computer shopper magazine I have laying around. Seems AMD tried hard to convince the public that their CPU's were faster as they rated them against higher clocked Intel CPU's. ie.. they say a 400MHz K6-2 is faster than a PII 450MHz. Maybe it is for a specific application or bench mark. But I can say with confidence that it is not in real life.

Which is why I asked if somebody has a XP system to post some numbers. I am going to be holding firm on my belief that AMD's MHz myth is... well the same advertising hype they pulled on the older cores.

I am also looking at this the wrong way. For putting together those 4 systems... back in 97 and 98 it would have costed me over $3500 in parts :Q. I should really be happy as my town is somewhat isolated and I can probably sell each of those systems for $550 +/- 🙂. Although I do not know if I will do that for morality reasons.

Sorry, not running SOB here - just seti.

I can tell you the seti WU time diff between a K6-2 500 and an AMD XP2400 tbred and a P3 700 running at 933 mhz.
All my own systems, so this is from personal experience.

K6-2 500 ran a .417 AR WU @ 48 hours
P3 933 runs a .417 AR WU @ 6 hours 24 mins
AMD XP2400 tbred runs a .417 AR WU @ 3 hours 10 mins

The XP2400 is running a 2.0 Ghz
The K6-2 500 and the XP2400 both were running Windows XP pro and the P3 is running Windows 2000 server.
The K6-2 had about 196 megs ram, 100 mhz FSB.
The P3 has 256 megs PC 133 ram and is running at fastest mem timings
The XP2400 has 512 megs PC2100 ddr and is running at fastest mem timings, stock cpu speed (no OC)

All that being said, the fastest (most expensive) P4 cpu's are turning in the best seti WU times these days.
But they are very expensive so your WU/dollar ratio is still likely better with the AMD.
 
The K6's rampaged on Dnet's CSC project. We were organizing trades to get as many K6's on CSC as possible, back in the day. They also walked all over (get this) the P4 on a per-MHz basis in RC5-64. But that's not saying much, because everything else walked all over the P4 in RC5-64 too.

I am seeing around 1100000 cEM/second on my 1400MHz AthlonXP, which comes out to about 785 cEM/second per MHz. Your P2 233 is getting about 115 cEM/second per MHz, so the AthlonXP/DDR platform is about 7 times as productive as the P2/SDRAM platform, on a per-MHz basis. 😀

Big edit: I got too many zeros in that! 😛 it's now doing 115670 cEM/second, so I was off by a factor of 10, and the AthlonXP/DDR platform ends up being 0.7 as efficient as the P2/SDRAM platform (per MHz). D'oh! 😱
 
Mech...

Those were the days... when every drop of Mhz where needed.

Where in the heck are the old timers ?!?!?!

Hey dudes, show yourself.... roll call for the third age...


Damm, i miss my farm
 
Welcome back, StormGiant! I haven't seen you since the giantnt4vizmechthunderstorm! 🙂

We need to do some more benchmarking, and find out what processor is good for what nowadays. And also what needs fast ram, since I'm sure there are a lot of systems with bad ram out there.
 
I updated my post with correct numbers, was off by a factor of ten! 🙁

Nice to see you here again Stormgiant! 😀
 
Welcome to the team. I did not realize you were a new member 🙂.

Very impressive numbers your putting out. Rivals some of the top producers 🙂. You should come up in the ranks quickly 😀.

Glad to have you with us 🙂

I think I started rc5 after reading about DES finishing in under 1 day. Started on 4/8/1999. Almost 4 years of this stuff and I still don't have a fleet.
 
Wow a rare sighting of Stormgiant!😀
I still remember those long gone days of when you put out some good numbers in SETI😉

I don't know anything about SoB but I do know a little about K6-2's😉
K6-2 vs PII
PII has 1/2 cpu speed cache ,K6-2 has cache at FSB MHz
PII has a much better FPU ,about 40% faster at the same clock speed
K6-2 has better Intger peformance than a PII ,hence they were so good at RC5.

The Athlon is light years ahead of the K6-2 so don't hurt the Athlons feelings by comparing them😉 ,the XP number rating vs P4 MHz is far more realisitic than the old K6-2 MHz comparision to PII (not to say its pefrect though😛)
 
I was starting to get the same feeling of the matter after a little more studying.

However short of these older AMD's which seem to be bullet proof. I completely left the AMD scene as I kept on having stability issues even with the newest drivers/patches. I do not have those problems with Intel and the constucted price of a good OC'able P4 costs less or in some instances slightly more than a AMD setup. So I just assume not deal with those problems for myself and build Intel systems. I do build AMD computers though, just not for myself at the moment. So don't think I am Pro-Intel, I will just go with whatever I feel is stable and gives the most bang for the buck.

Ahh yes, most importantly stay away from prebuilt computers unless you are looking for a small foot print type of computer. Although I am sure everyone here knew that already.
 
The K6-2 Chip was indeed faster than the original PII in some respects, but its FPU sucks ass. If you come accross any (and ur mobo's support em) the K6-3 is a lot faster than the K6-2, and the K6-2+ and K6-3+ are even faster still, but even rarer too. Incidently there are quite a few different things you have to make sure are enabled with older motherboards cos sometimes their BIOS doesn't do it by default. There's a list somewhere along with a util that does it for ya, must dig it out ........

PS I'm running a Pentium Classic 166 so don't talk to me about slow 😀 (on Win2k no less)

Absoluely perferct for internet and office applications, not sure what else though. On a P166MMx I had just goofing around, I put in a 16MB AGP video card and a 7200rpm drive. Simply put it smoked all other regular pentium and penium MMx's series I seen. But I later turned that internal equipment to a AMD K6-2 400MHz.
