The charts in the section below illustrate performance of Core 2 Duo E4500 and Pentium E5700 processors in a few different types of tasks. To calculate displayed numbers we averaged results for a number of tests for each specific type of application. As a result, performance in individual benchmarks may be lower or higher than what you see in Average Bench 51.1%. 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 A single core CPU is capable of carrying out all of the calculations required to run a computer, tablet, or smartphone as well as its applications. At some point, manufacturers started to put multiple cores on the CPUs of our everyday devices. This caught on quickly. Most popular devices today are dual core (two cores) or quad cores (four cores). Seagate Barracuda 2TB (2016) $64. G.SKILL Trident Z DDR4 3200 C14 4x16GB $354. SanDisk Ultra Fit 32GB $16. Based on 71,029 user benchmarks for the Intel Core2 Duo E8400 and the Pentium Dual E2140, we rank them both on effective speed and value for money against the best 1,431 CPUs. Benchmarks of Low End CPUs. This chart comparing low end CPUs is made using thousands of PerformanceTest benchmark results and is updated weekly. A Quad-Core CPU is not a REQUIREMENT to run several applications, they’ll just run slightly faster. A Dual-Core CPU can ALSO run several applications (thanks to a technology called Task Parallelism) which means even though you are running 4 or 5 applications simultaneously, they can all still run on TWO or even ONE CORE. Average Bench 52.9%. ADVERTISEMENT. 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% wOJD.
