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]


The Intel Core i5-3210M is a third generation (Ivy bridge) mobile CPU. Sporting two cores and four threads the 3210M has a maximum turbo clock speed of 3.1 GHz which produces an effective speed of 64.4 or 52% below the modern day group average . For heavily threaded tasks the 3210M is handicapped significantly by its dual core architecture and lags modern CPUs by around 165%. The i5-3210M comes equipped with onboard HD 4000 graphics, which is more than enough for typical desktop use but will struggle with anything but the simplest of 3D games. With a TDP of just 35 Watts the i5-3210M allows for reasonable, but not brilliant, battery life. [Oct '14 CPUPro]
