SanDisk Extreme 32GB $28. Seagate Barracuda 2TB (2016) $64. G.SKILL Trident Z DDR4 3200 C14 4x16GB $364. SanDisk Ultra Fit 32GB $16. Based on 74,012 user benchmarks for the Intel Core2 Duo E7400 and the Core2 Quad Q6600, we rank them both on effective speed and value for money against the best 1,429 CPUs. The Intel i5-8400 packs many more processing cores than the Intel Core 2 Duo E8400. Large number of cores helps this processor to process multiple applications or heavily multi-threaded tasks. The i5-8400 has SSE4.2 instructions enabled. The Core i5-8400 incorporates Advanced Encryption Standard instructions, that accelerate AES encryption. The charts in the table below demonstrate relative performance of Core 2 Duo E7500 and Pentium E5500 microprocessors in various kinds of programs. 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.
