There are 2 types of Core processor, Solo and Duo. Core Solo means it has only one processor in its chipset, while Core Duo means it has 2 processors in one chipset similar to Pentium Dual Core and Centrino Dual core. The most sophisticated processor at the moment is the Core 2 Duo Extreme with up to 3.2GHz clock speed which uses the 64bit C7Xq. Most Xeon processors have 15-30MB and as much as 50MB+ of L3 cache depending on the model, close to double their i7 counterparts. This extra cache is one reason why Xeons are often so much faster 46 Comments Core Duo vs. Core 2 Duo We've spent a lot of time comparing Intel's Core architecture to NetBurst and AMD's K8; however, we've stayed away from quite possibly one of the most Price and performance details for the Intel Core2 Duo T5200 @ 1.60GHz can be found below. This is made using thousands of PerformanceTest benchmark results and is updated daily. Seagate Barracuda 2TB (2016) $64. G.SKILL Trident Z DDR4 3200 C14 4x16GB $354. SanDisk Ultra Fit 32GB $16. Based on 346,747 user benchmarks for the Intel Core i7-3770 and the Core2 Duo E8400, we rank them both on effective speed and value for money against the best 1,429 CPUs. The range of scores (95th - 5th percentile) for the Intel Core2 Duo P7450 is just 19%. This is a relatively narrow range which indicates that the Intel Core2 Duo P7450 performs reasonably consistently under varying real world conditions.
