Chessbase got often sponsoring from computer society Dual Athlon MP 2000+ in in Leiden 2002 : http://www.chessbase.com/newsdetail.asp?newsid=339 Even 2 servers for Kasparov-Junior match : http://www.chessninja.com/dailydirt03.htm And a server for the Kramnik-Fritz match too > How do you came to the conclusion, >that such a machine would give two extra plies?

I counted with a 2.5 branching factor : As you can see here the memory management for the opteron is better than the Athlon (who is bad in dual configuration) http://www.aceshardware.com/read.jsp?id=55000253 a Dual AMD Athlon MP 2100 translate into 2100+0.7*2100 = 3570 "usefull Mhz" a 8-way AMD64 3200+ translate into 3200+0.7*7*3200 = 18880 "usefull Mhz" 5.3 faster + better memory management -> about 2 ply deeper >I doubt that >anyone will use an opteron machine, since I think nobody will be able to rewrite The AMD64 don't need a rewrite, they run 32 bits applications and a simple recompile with suited compiler can give + 15% performance >his program for 64Bit architecture until the event.
