The K7 is simply *way* faster for the vaste >*majority* of chessprograms. It is well known that the 760MP chipset should have been improved upon by AMD as they got faster in terms of the memory management. But, before you get even more annoyed read further... >Just try 20 programs at it and you'll see. I don't have a basis of comparison for these others. I am a big fan of non-commercial engines and run tournaments frequently between many of these programs. >So wake up. open your eyes. there is another 200 engines or so. First part of that is unnecessary, I merely did not have a basis of comparison for the results I was getting with my box. Would be great to have a webpage devoted to chess benchmarks. And, for the record, I have around 260 engines on my HD at the moment :) (a lot of them different versions of the same engine) >And those are *not* on par. > >Here is the problem of fritz.

Interesting. I did see the Diep benchmarks you had posted for Ace's Hardware a ways back for the older chips. Also interesting. >Of course the marketing department never told you fritz doesn't know the diff >between a bishop and a knight.

I honestly would like to know as I will be buying a dual when the 2GHz chips come out. >I'm not sure Frans is going to do effort to rewrite his entire assembly to >x86-64 :) > >Where others can efficiently work on the knowledge or search or whatever, he has >to recode for a full year his engine in order to run at such a new architecture. > >All i need is someone else (Nalimov?) sweatting creating a 64 bits x86-64 visual >c++ compiler. If not then i'll go for 64 bits GCC at the opteron. I'm confused, the original discussion was about MP's versus Xeons. I wholeheartedly agree that Opterons, even with 32-bit software will blow everything else out of the water. >And if that ain't enough then i'll take a bit older compiler (mipspro) and just >get 500 cpu's :) >Frans on the other hand is really outdated busy.

That includes Fritz, Shredder (which I've been using a lot lately), DJ, and any other CB, UCI, or WB (via wb2uci of course) engine you want. Not sure how you got kicked into this Fritz-bashing session :). Anyways, objective information is far more important to me than patriotism to a company (which was why I went Xeon in the first place despite my greater respect for AMD, because it did what I did buy this machine for better, which was not chess). But, like I said before, I simply don't have anyone with an MP system or any webpage to go to when I run, say, Ruffian, or Deep Sjeng, or whatever to compare it to. The observations that I had made were based off of the only means of comparison I did have. And, TBH, they took me by surprise. If you have a resource that'll allow me to do this, I'd be very interested in using it. I know you've been in this game for a long time, so I respect what you say on this matter. Ran across this link that evidences your viewpoint: http://www.tecchannel.de/hardware/1164/9.html Also, offtopic for this discussion, but I would like to run an SMP tournament with the same conditions as the RK2003 tournament. I would like to include Diep in this, is this privateware? freeware? commercial? The links I've seen pointing to a Diep homepage are dead.
