As a dual-core CPU, the Core Duo has twice the amount of processing power as the Core Solo. Speed and Motherboard Clock or processing speed on the Core Solo ranges from 1.06GHz on the U1300 to 1 Compare the technical characteristics between the group of processors Intel Core 2 Duo and the processor Intel Celeron N4020. We also have a comparison of the respective performance with benchmarks, such as PassMark, AnTuTu if available, Cinebench, CPU-Z, and Geekbench. Note: Commissions may be earned from the links above. Difference Between Dual Core Processors and Core 2 DUO Processors: Dual-Core processors are those that contain two cores in a single silicon chip, while Core 2 Duo is the name given by Intel to its second batch of Dual-Core processors. Learn more on Dual Core Processors and Core 2 DUO Processors. Dual Core is a type of processor with two cores on a single chip, while i3 is a processor developed by Intel. Dual Core processors are generally slower and less powerful than i3 processors. Dual Core processors are suitable for basic tasks like web browsing and document editing. In contrast, i3 processors are more powerful and suitable for more Seagate Barracuda 2TB (2016) $64. G.SKILL Trident Z DDR4 3200 C14 4x16GB $364. SanDisk Ultra Fit 32GB $16. Based on 105,502 user benchmarks for the Intel Core i5-1135G7 and the Core2 Duo E8400, we rank them both on effective speed and value for money against the best 1,429 CPUs. About the Athlon X2 4400 vs. Dual Core E2200, the link for benchmarks on rendering shows an indirect comparison, but the information is there. The timing for the 2.3 GHz X2 4400 are up (114), but the closest results for the 2.2 GHz E2200 Dual Core are the 1.8 GHz E2160 Dual Core (114), which indicates the E2200 would be faster than the E2160, which is the same as the X2 4400. Dual-core CPU: Processors with 2 cores, such as the Intel Core Duo and AMD X2. Quad-core CPU: Processors with 4 cores, such as most Intel 6th and 7th generation chips. Hexa-core CPU: Processors with 6 cores, such as the Ryzen 5 Pro 1600 and Intel i5-8420T. Octa-core CPU: Processors with 8 cores, such as the AMD Ryzen 7 7700X and Intel i7-9800X.
