The Core i3 CPUs are based on Intel's newer 'Nehalem' CPU architecture which is around 10% faster, clock for clock (i.e., with both CPUs at the same speed) than the Core 2 Duo, based on the older Core 2 architecture. Overall, the Core i3 is a bit faster than the Core 2 Duo E7000 series, and slightly faster than the Core 2 Duo E8000 series in G.SKILL Trident Z DDR4 3200 C14 4x16GB $364. SanDisk Ultra Fit 32GB $16. Based on 45,170 user benchmarks for the Intel Core2 Duo E7500 and the Pentium E6700, we rank them both on effective speed and value for money against the best 1,429 CPUs. Compare the technical characteristics between the group of processors Intel Core 2 Duo and the group of processors Intel Core i5. We also have a comparison of the respective performance with benchmarks, such as PassMark, AnTuTu if available, Cinebench, CPU-Z, and Geekbench. Note: Commissions may be earned from the links above. Core 2 Duo vs Dual Core. Thread starter melted head2; Start date Mar 30, 2007; Status Not open for further replies. M. melted head2. Mar 30, 2007 #1 hi need some help! It is a dual core processor, but it is relatively faster than other dual-core processors because of its larger cache memory and ability to overclock that allow users to multitask. Conroe, the first-gen Core 2 duo chip, replaced the Pentium D and Pentium 4 processors, which improved performance by up to 40 per cent. If u run vista ur extra cores will take care of other tasks. Dual core is best with games currently because of higher clocks but the difference isnt much. a quad cores can oc to over 3.0ghz so the difference between the 2 cpus is like a 2-5fps max. But if u dont oc the dual core has a slight edge. It is the extensive version of Dual core processor. Core 2 duo has better performance than Dual core as it has better overclock ability than Dual core. In Core 2 duo processor there is 6 MB of L2 cache memory. In Core 2 Duo processor, we can overclock it up to 4.0 GHz. Due to high clock speed/overclock ability, it can execute multiple task Intel Core 2 Duo E6700: 2.66GHz: 4MB: $530: Intel Core 2 Duo E6600 : 2.40GHz: 4MB: $316: AMD Athlon 64 X2 5000+ Today we'll find out for sure if the E6300 will be the low-cost dual core CPU to .
