Architectural Overview
The Intel Xeon E5440 is a quad-core processor based on the Wolfdale microarchitecture, while the Core 2 Duo E8400 is a dual-core processor based on the Penryn microarchitecture. Both processors use the 45nm process technology.
Core Count and Clock Speed
The Xeon E5440 has four cores, while the Core 2 Duo E8400 has only two cores. However, the Core 2 Duo E8400 has a higher clock speed of 3.0GHz compared to the Xeon E5440’s 2.83GHz.
Cache Memory
The Xeon E5440 has a larger cache memory than the Core 2 Duo E8400. It has 12MB of L2 cache and 16MB of L3 cache, while the Core 2 Duo E8400 has only 6MB of L2 cache.
FSB Speed
The Xeon E5440 has a faster front-side bus (FSB) speed of 1333MHz compared to the Core 2 Duo E8400’s 1066MHz. This means that the Xeon E5440 can transfer data between the processor and the memory faster.
Virtualization Support
The Xeon E5440 supports Intel Virtualization Technology (VT-x), which allows it to run multiple virtual machines simultaneously. The Core 2 Duo E8400 does not support VT-x.
Power Consumption
The Xeon E5440 has a higher power consumption than the Core 2 Duo E8400. It has a thermal design power (TDP) of 80W, while the Core 2 Duo E8400 has a TDP of 65W.
Performance Comparison
In terms of performance, the Xeon E5440 typically outperforms the Core 2 Duo E8400 in multi-threaded applications that can take advantage of its four cores. However, the Core 2 Duo E8400 may perform better in single-threaded applications due to its higher clock speed.
Which One Should You Choose?
The Xeon E5440 is the better choice for performance-oriented users who need a processor with multiple cores and a large cache memory. It is ideal for applications that require intensive processing, such as video editing, 3D rendering, and scientific computing.
The Core 2 Duo E8400 is a good choice for users who are on a budget or who do not need the extra performance of a quad-core processor. It is suitable for general computing tasks, such as web browsing, office productivity, and gaming.
Key Points
The Intel Xeon E5440 and Core 2 Duo E8400 are both capable processors, but they have different strengths and weaknesses. The Xeon E5440 offers superior performance in multi-threaded applications, while the Core 2 Duo E8400 is more affordable and has a higher clock speed. By understanding the key differences between these processors, you can make an informed decision about which one is right for your specific needs.
