both are Intel,
1st one says:
Intel 05
PENTIUM D
925 SL9D9 Costa Rica
3.00GHZ/4M/800/05A
3626B680
and the second says:
INTEL 05
INTEL core 2 duo
6300 SL9SA MALAY
1.86GHZ/2M/1066/06
L627A566
So which one should i use/which is the best?
core 2 duo because its l2cache is larger and is 2MB L2 cache per core and runs at 1066FSB with a 9x Multiplier. While the Pentium D has a 1MB L2 cache per core and runs at 533FSB. The core 2 duo is faster.
Take a look at this article with the pentium D and core 2 duo being compared.
