AMD 4000+ dual core would be my choice (as its a good seller) but... Performance wise they are all very close
Another factor is the FSB ((Front Side Bus) Speeds) Intel chips run mostly at 533 Mhz ,but the AMD chips move data @ 1000 MHZ or More Have you got the SETI/BOINC program running? I upgraded from a AMD Athlon XP 2000+ chip to this AMD Athlon 64 4000+ (New motherboard too) This was running on a 533 FSB M/B Chip rated real terms 1.7 Ghz (clock speed) Process the same size Seti workunit (10 hours to complete) as to My latest 4000+ (1200mhz FSB board ) Real speed 2.4 Ghz and you'd think the apparent "slow clock speed" will slow matters down
Well here are the results... That same 10 hour unit is "seen" by the 4000+ chip and fast FSB Board as just 2 and a Half Hours Defo worth a expression Last word on these chips You can tune them to get even more Performance But Who wants to go up that Path? They Pedal fast enough for my purposes. Want more performance? I'd buy a New chip rather than risk a Burnout! They run Hot Hence the Ventilated case design(I have 2 Massive Fans on the Front and 5 internally)Noisewise not Nuch more than the old 4 fan setup. Was it the Prescott core chip that was the Hottest running, and Case makers had to make provision for cooling that?
