Has it ever? No, currently the list of top hosts is clearly dominated by Intel Core 2 CPUs. The one AMD computer you will find in the top ranks needs twice as many cores as the Intel PCs to achieve its performance.

This is not an Einstein@Home specific observation, many other projects will show the same.

AMD was dethroned a year and a half ago by the C2D processesor and has yet to recover from the blow.

The positions may be reversed next year ...

It is a see-saw battle ...

So, what you need is 10 machines ... 5 AMD ... and 5 Intel ... and when AMD is up you upgrade the AMD machines with new processors ... and when Intel is up you will be just about done with that and ready to start upgrading the Intel based machines ...

To the OP - you're showing that you haven't been paying attention for the last two years or so :-). Sadly AMD was dethroned quite a while ago and doesn't seem to be able to even get back into the race, let alone get anywhere near the top again.

However, the good thing is that some AMD64s are now starting to come through in used computer auctions. A week ago, I bought a box that was listed as "AMD64 3800+ CPU, 1GB RAM, 40GB HDD". It cost me $USD60 and when I got to investigate, it had an ASUS A8N-SLI socket 939 mainboard, 2x512 decent OCZ RAM and the CPU was an X2 socket 939 dual core. There was also a DVD burner and the HDD was an 80GB SATA. I was rather pleased with that purchase :-). I've overclocked it a reasonable amount and it's producing 7 tasks per day so it should have a RAC of around 1500 or more when it plateaus. For a day or two it was my fastest machine by a big margin :-).

At another auction, I bought some gear from a computer company that had gone into liquidation. I ended up with a nice (and very cheap) selection of mainboards, PSUs and cases, and various other items that were from stock and therefore unused. I decided to build a new system on an ASUS AM2 mainboard I got in this lot so I bought an X2 4600+ and a 2GB kit of DDR2 800 RAM for about $USD110 and built a system in one of the cases I had acquired. This new machine is also overclocked a bit for now with more to come when I get a time to play with it. Ir should end up with a RAC closer to 2000 so it will then be my fastest machine. My fastest Intel machine is a quad Xeon 2.4G server but the two AMD X2s are way out in front now :-).

@Bikeman - Yes, AMD was King a few years ago. When Einstein opened its doors at the start of 2005, I had two reasonably newish machines which had been put together about a year earlier. One was a 2.6GHz Northwood P4 and the other was a 1.667GHz Athlon XP 2000+. I was able to overclock the Athlon to 2.15GHz. Even without overclocking, it was more than a match for the P4 and it was so much cheaper as well. Those were the good old days when AMD really had a significant advantage over Intel. Hopefully those days will come again.

Cheers,
Gary.

But my Opteron 1210 at 1.8 GHz, costing 75 $,is bravely holding its own against Pentium D, Core 2 DUO, Xeon of my wingmen and is beated only by four core chips, both Intel and AMD.

Hi Tullio - I don't think your machine would quite be keeping up with C2Ds but it is indeed a nice machine for the price.

I notice your results are averaging around 9 hours. My X2 3800+ (which is overclocked but only about 10% so far until I get time to do the job properly) is taking around 7 hours so I'm quite pleased with how it is performing. I've seen C2Ds that are doing tasks in less than 5 hours so we both have quite a way to go to get into that league :-).

Cheers,
Gary.

Thanks, Gary. It is a nice machine indeed, a SUN WS with 6 USB ports, 2 Ethernet ports, 2 Firewire ports, three PCIe and three PCI slots, four DDR2 memory slots. I brought it to 2 GB RAM with 4 512 MB units. L2 cache is 2 x 1024 KB. One SATA disk holds 160 GB but I can add another, Only drawback is a ROM only DVD unit by I can change it. It was finely engineered. I paid it 700 euros with keyboard and mouse, excluding monitor, that is more than the average PC price, but I am satisfied with it. It had Solaris installed, but I switched to SuSE Linux 10.3 to avoid complications. Cheers.

Oh, I see ... Was the 75 $ you mentioned in your previous message just a typo?

I thought a dual opteron for $75 was a fantastic deal you had achieved :-).

Gary.

That was only the CPU in USA. But in Italy a spare 1210 would cost me 570 euros..
