Architecture and Core Configuration
The AMD Opteron X3421 is based on the Bulldozer architecture, featuring four cores and eight threads. Each core is equipped with 2MB of L2 cache, resulting in a total of 8MB of L2 cache for the entire processor. On the other hand, the Intel Xeon E3-1220LV2 is built on the Sandy Bridge architecture, boasting four cores and eight threads as well. However, it comes with a larger L2 cache of 10MB, providing each core with 2.5MB of dedicated cache.
Clock Speed and Turbo Boost
The AMD Opteron X3421 operates at a base clock speed of 2.9GHz, which can be boosted up to 3.3GHz using Turbo Core technology. This allows the processor to dynamically adjust its clock speed based on workload demands, optimizing performance while maintaining energy efficiency. In contrast, the Intel Xeon E3-1220LV2 has a lower base clock speed of 2.3GHz but can reach a higher Turbo Boost frequency of 3.5GHz. This makes it suitable for applications that require consistent high performance, even under sustained loads.
Power Consumption and Thermal Design Power (TDP)
The AMD Opteron X3421 has a TDP of 30 watts, indicating the maximum amount of heat it can dissipate. This makes it an excellent choice for compact and energy-efficient servers where space and power consumption are critical considerations. In comparison, the Intel Xeon E3-1220LV2 has a TDP of 17 watts, making it even more power-efficient. This lower TDP allows for greater flexibility in server design and cooling solutions, enabling denser server configurations.
Memory Support and Expandability
The AMD Opteron X3421 supports up to 128GB of DDR3 memory, while the Intel Xeon E3-1220LV2 supports up to 32GB of DDR3 memory. Both processors feature dual-channel memory architecture, allowing for higher memory bandwidth and improved performance. However, the Opteron X3421’s higher memory capacity makes it more suitable for memory-intensive applications, such as virtualization and database servers.
Performance Benchmarks
To evaluate the real-world performance of these processors, let’s examine some benchmark results. In the SPECint2006 benchmark, which measures integer performance, the AMD Opteron X3421 scores 138 points, while the Intel Xeon E3-1220LV2 scores 145 points. This indicates that the Xeon E3-1220LV2 has a slight edge in integer performance. However, in the SPECfp2006 benchmark, which measures floating-point performance, the Opteron X3421 takes the lead with a score of 145 points compared to the Xeon E3-1220LV2’s score of 138 points.
Features and Technologies
Both the AMD Opteron X3421 and Intel Xeon E3-1220LV2 offer a range of features and technologies to enhance performance and security. These include support for virtualization, error-correcting code (ECC) memory, and advanced power management features. However, the Opteron X3421 stands out with its support for AMD-specific technologies such as Turbo Core, which dynamically adjusts clock speeds for optimal performance, and HyperTransport, a high-speed interconnect technology for efficient data transfer between the processor and other components.
Choosing the Right Processor for Your Needs
Ultimately, the choice between the AMD Opteron X3421 and Intel Xeon E3-1220LV2 depends on your specific requirements and budget. If you prioritize energy efficiency and compact design, the Xeon E3-1220LV2 with its lower TDP is an excellent option. However, if you need higher memory capacity, support for AMD-specific technologies, and better floating-point performance, the Opteron X3421 is the way to go.
