Core i5-2400 and Core 2 Duo E8400 basic parameters such as number of cores, number of threads, base frequency and turbo boost clock, lithography, cache size and multiplier lock state. These parameters indirectly say of CPU speed, though for more precise assessment you have to consider their test results. We compare the technical data and benchmark results. The Intel Core2 Duo E6600 has 2 cores with 2 threads and clocks with a maximum frequency of 2.40 GHz. Up to 16 GB of memory is supported in 2 memory channels. The Intel Core2 Duo E6600 was released in Q3/2006. The Intel Core 2 Quad Q9400 has 4 cores with 4 threads and clocks with a maximum Chip lithography. 65 nm. 14 nm. Power consumption (TDP) 65 Watt. 6 Watt. The Celeron N4020 is our recommended choice as it beats the Core 2 Duo E6600 in performance tests. Be aware that Core 2 Duo E6600 is a desktop processor while Celeron N4020 is a notebook one. The charts in the table below demonstrate relative performance of Core 2 Duo E7500 and Core 2 Duo E8400 CPUs in a few different task types. The numbers for 'Single-threaded performance' and 'Multi-threaded performance' charts are calculated as an average of several related benchmarks, that you can find in the "Benchmarks" tab. Consequentally, the shown results may differ from results, that you 0. 65W. 65W. Lower is better. - Intel Core 2 Duo E4500 - Intel Core 2 Duo E8400.
