The graphs below compare the most important characteristics of the Intel Core 2 Duo E6700 and Intel Pentium E2200 processors. These features, along with an IPC (instructions per cycle) number, determine how well a CPU performs. Darker area on the "On-chip cache" graph is for the On-chip L1 cache. Lighter area is for the L2 cache cache. The table below compares support for x86 extensions and technologies, as well as individual instructions and low-level features of the Intel Core 2 Duo E4300 and Intel Pentium E2180 microprocessors. Information in this table was retrieved from actual processors using CPUID instruction, and we also utilized internal timer to measure CPU frequency. Seagate Barracuda 2TB (2016) $64. G.SKILL Trident Z DDR4 3200 C14 4x16GB $364. SanDisk Ultra Fit 32GB $16. Based on 77,430 user benchmarks for the Intel Core2 Duo E8400 and the Pentium E5800, we rank them both on effective speed and value for money against the best 1,429 CPUs. VID - Video card (s) 1. MSI R6670 1GB GDDR5 (ATI RADEON) 2. POWERCOLOR 24PRO256M DDR2 (ATI RADEON HD2400) The table below compares support for x86 extensions and technologies, as well as individual instructions and low-level features of the Intel Core 2 Duo E6600 and Intel Pentium G3240 microprocessors. Seagate Barracuda 2TB (2016) $50. G.SKILL Trident Z DDR4 3200 C14 4x16GB $363. SanDisk Ultra Fit 32GB $16. Based on 22,679 user benchmarks for the Intel Core2 Duo E7400 and the Pentium Dual E2200, we rank them both on effective speed and value for money against the best 1,429 CPUs. Below is a complete set of Intel Core 2 Duo E6550 and Pentium E5400 benchmarks from our CPU benchmark database. Both microprocessors were tested on ASRock 4Core1600Twins-P35 motherboard with 2 GB dual-channel Corsair CM3X1024-1333C9 DDR3 memory, and Powercolor 24PRO256M DDR2 (ATI Radeon HD2400) graphics. All tests were performed at default 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 9,808 user benchmarks for the Intel Core2 Duo T9900 and the Pentium T4500, we rank them both on effective speed and value for money against the best 1,429 CPUs. Below is a complete set of Intel Core 2 Duo E8600 and Pentium E6800 benchmarks from our CPU benchmark database. Both microprocessors were tested on ASRock 4Core1600Twins-P35 motherboard with 2 GB dual-channel Corsair CM3X1024-1333C9 DDR3 memory, and Powercolor 24PRO256M DDR2 (ATI Radeon HD2400) graphics. All tests were performed at default The Pentium Dual Core was only a Core 2 Duo with reduced Cache and clock speeds. The clock speeds got in the 2.5ghz range 1-2 years after it was released. It is really not even right to compare these two processors because the fact that every single Pentium Processor since the Pentium 1 to the Pentium D ran on the Netburst architecture. The charts demonstrate relative performance of Core 2 Duo E6700 and Pentium E5400 CPUs in a few different task types. 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. Consequentally, performance in individual benchmarks may be lower or higher than what you zZRK.
