Average Bench: 24.1% (632nd of 969)

Based on 15,583 user benchmarks.  Devices: BFEBFBFF00010676, , BFEBFBFF0001067A Model: Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz

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 modern day counterparts. The relative lack of performance is especially noticeable in the area of multi-core processing as a consequence of the E8400's relatively few two cores. Anyone considering an upgrade needn't hesitate as modern CPUs are not only orders of magnitude faster but also considerably more energy efficient and feature packed. [Oct '14 CPUPro]
