cpu and memory MHZ question

1) which processor is better? the dv3-2155 T6400 2.1GHZ 800MHZ 2MB L2 or the dv3510nr P7350 2.0GHZ 1066MHZ 3MB L2?

2) the dv3510nr processor says 1066MHZ while it uses DDR2 memory at 667MHZ (from what i googled)....but DOESNT THAT SLOW EVERYTHING DOWN??? or is the memory actually 667x2 because of DDR2?

 

I'd take the dv3510nr, if anything it's newer which lets you upgrade to a better cpu down the road if you want. They're going to perform about the same.

The memory doesn't really slow the system down too much. The DDR-667 rating is already "doubled", it's running at 333MHz.

 

1) The raw performances of both CPUs should be equivalent. I would get P since it consumes 25Watts whereas the other one consumes 35Watts.

2) Yes, using DDR2-667 instead of DDR2-800 hurts the performance but it will be noticeable by synthetic tests. I don't think you will feel the difference at all. If you are really irritated you can replace the RAM's later by yourself without voiding the warranty. RAM prices are really low in these days.

ACTUALLY lol

The FSB is 266 Mhz which is quad pumped (transfer 4 times the data per clock cycle) and is RATED at 1066. The ram is double data rate, it is 333.5 Mhz and transfers 2 times the data per clock cycle so its rated at 667 Mhz.

333 Mhz on the ram is faster than the 266 Mhz bus speed. Myne is 400 Ram 266 fsb, stock it operates on a 2:3 ram ratio, not sure what the ratio is on yours but it doesnt matter. Faster rated ram can potentially improve performance through the simple fact it can transfer data faster. But it is NOT bottlenecked the way you think.
