I have used both AMD Athlon 64 X2 and the Intel Core 2 Duo ships in the past few months. Both have their advantages and disadvantage. I found that the Athlon 64 chips seemed to have a bit of a problem with Windows and core context switching. Using a real OS (*nix) this issue was nonexistent. There were several hacks that seemed to help. I have no actual experience with the new Turions or Opterons so I can't say if this condition has been corrected or not. If I was to get an AMD processor today, I would use an ATI graphics processor since the AMD 690 ship set is optimized for that family of GPUs
I currently run a Core 2 Duo E6600on a ASUS mobo with the NVIDIA chip set and NVIDIA graphics processor. It is a screamer. The Intel chip sets are probably a bit more robust, but tend to be more conservative in the performance arena. The "chip race" is alive and well between the Intel and AMD (which is great for the customer) as they go core crazy. IMHO, it comes down to cost (who really needs to pay the big $$ for a 48 core chip???), the amount of L2 cache on the processor and the mobo chip set when all other things are equal. Now, I really need to stress the point that the difference I note above are soooooooo miniscule that you will never notice them. They are really insignificant when it comes to running PowerSDR. Either are a good choice. BTW, do not worry about heat dissipation. Big fans are cheap. As far as EMI suppression, get a very good case with lots of steel (heavy) and no plastic "see thru" sides. I favor Antec in this arena. -Tim -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Steve Kallal Sent: Monday, July 02, 2007 11:54 PM To: FlexRadio@flex-radio.biz Subject: [Flexradio] Good motherboards??? I am ready to upgrade my system to a dual core processor. I have been attracted to Asus based on some comments I've seen on this reflector. I don't know whether to go with an Intel or AMD processor. I am inclined to go for the Intel because someone said the Intel's run cooler than the AMD's and use less power. In fact the Intel Core 2 Duo is supposed to use less power than my Pentium processor. I also wonder if less power consumption also translates to less EMI/RFI. Are the power consumption differences true? My source is a salesman. The Asus motherboards I am looking at are P5B and the P5N-E. These are for Intel processors. My main use is going to be the SDR-1000 and soon the FLEX-5000A. I welcome any comments pro or con. 73, Steve N6VL -------------- next part -------------- An HTML attachment was scrubbed...
