Same family. Same socket. Same CPU core. Slightly faster that the E6300, the E6400 microprocessor usually beats in benchmarks most of Intel Pentium 4s, including Pentium 4 Extreme Edition processors. Depending on the application, the E6400 may be as fast as Athlon 64 FX-62, but not slower than Athlon 64 FX-60. 0. 65W. 65W. Lower is better. - Intel Core 2 Duo E4500 - Intel Pentium E5400. Detailed side by side comparison of Core 2 Duo E4500 vs Intel Pentium E5400 specs can be found in the Specifications section below. More detailed comparison of low level features of both CPUs you will find in the CPUIDs section . Average Bench 41.3%. The Intel Core 2 Duo E8400 is amongst the fastest of the Core 2 Duo range of now nearly ten year old CPUs. The E8400 is included in our group tests simply as a reference point due to its huge success back in its day. Running at a clock speed of 3.0 GHz the E8400 has an effective speed of 52 which is 85% slower than its In reply to difference between Dual core and core 2 duo processor technology The basic difference is the “cache memory”. Dual core have dedicated cache on the other hand the c2d have the shared . Difference Between Dual Core Processors and Core 2 DUO Processors: Dual-Core processors are those that contain two cores in a single silicon chip, while Core 2 Duo is the name given by Intel to its second batch of Dual-Core processors.
