I want to buy a PC to run an application I wrote. It's compiled for 32bit systems, so I want to stay away from 64 bit processors. It makes heavy use of threads, eats up a lot of memory, for CPU intense (it's a scientific application). I'm taking a look at this dell configuration:
Processor-wise I'm confused. Here are the options:
Intel" Core®2 Extreme QX6850 (3.00GHz/1333MHz/2X4MB L2) 525W [add $1,329]
Intel" Core®2 Quad Q6700 (2.66GHz/1066MHz/2X4MB L2) 525W [add $659]
Intel" Core®2 Quad Q6600 (2.40GHz/1066MHz/2X4MB L2) 525W [add $339]
Intel" Core®2 Duo E6850 (3.00GHz/1333MHz/4MB L2) 525W [add $329]
Intel" Core®2 Duo E6750 (2.66GHz/1333MHz/4MB L2) 525W [add $219]
Intel" Core®2 Duo E6550 (2.33GHz/1333MHz/4MB L2) 525W [add $89]
Intel" Core®2 Duo E8500 (3.16GHz/1333MHz/6MB L2) 525W [add $329]
Intel" Core®2 Duo E8200 (c) 525W [add $139]
Intel" Core®2 Duo E4600 (2.40GHz/800MHz/2MB L2) 525W [Included in Price]
Intel" Core®2 Extreme QX9650 (3.00GHz/1333MHz/12MB L2) 525W [add $1,329]
Intel" Core®2 Duo E8400 (3.00GHz/1333MHz/6MB L2) 525W [add $249]
1) What's the difference between a Core2 Duo vs a Core®2 Quad? I'm guessing:
Core®2 Duo = 2 processors each with 2 processors on board - windows sees this as a PC with 4 processors.
Core®2 Quad = 4 processors each with 2 processors on board - windows sees this as a PC with 8 processors.
Is that right? Since I have to run WindowsXP, I thought that it could only take advantage of 4 separate processors anyway, so would the Core®2 Quad be useless?
2) Also, what's the difference between a Core 2 Duo, and a motherboard that just has 4 individual processors? Performance of any sort?
3) Lastly, what's the "2.66GHz/1333MHz/6MB L2" really mean? I know the 2.66GHz is the clockspeed of each processor, what's the 1333MHz/6MB L2 mean and how will it affect performance?
I'd really like to get the processor configuration that's going to let this app crunch the numbers as fast as possible,
