The AMD EPYC 7R32 and AMD EPYC 7R13 are two powerful server processors from AMD’s EPYC 7003 series. Both processors offer exceptional performance and efficiency for various enterprise and high-performance computing applications. In this blog post, we will compare the AMD EPYC 7R32 and AMD EPYC 7R13 in detail to help you make an informed decision when choosing the right processor for your server needs.
Core Configuration and Clock Speeds
The AMD EPYC 7R32 features 32 cores and 64 threads, while the AMD EPYC 7R13 has 24 cores and 48 threads. The EPYC 7R32 has a base clock speed of 2.2 GHz and a turbo boost speed of 3.4 GHz, whereas the EPYC 7R13 has a base clock speed of 2.0 GHz and a turbo boost speed of 3.2 GHz. The higher core count and slightly higher clock speeds of the EPYC 7R32 give it an advantage in multi-threaded workloads.
Memory Support and Bandwidth
Both the AMD EPYC 7R32 and AMD EPYC 7R13 support up to 1 TB of DDR4 memory with speeds of up to 3200 MT/s. However, the EPYC 7R32 has eight memory channels, while the EPYC 7R13 has only six memory channels. This means that the EPYC 7R32 can provide higher memory bandwidth, which is crucial for applications that rely on large memory datasets.
Cache Sizes
The AMD EPYC 7R32 has a total of 128 MB of L3 cache, while the AMD EPYC 7R13 has 96 MB of L3 cache. The larger cache size of the EPYC 7R32 can reduce memory latency and improve overall system performance, especially for applications that frequently access large amounts of data.
Power Consumption and Efficiency
The AMD EPYC 7R32 has a TDP (Thermal Design Power) of 225W, while the AMD EPYC 7R13 has a TDP of 180W. The lower TDP of the EPYC 7R13 makes it more energy efficient, which can reduce operating costs in data centers.
Virtualization Support
Both the AMD EPYC 7R32 and AMD EPYC 7R13 support AMD’s Secure Encrypted Virtualization (SEV) technology, which provides enhanced security for virtualized environments by encrypting virtual machine memory. This feature is essential for protecting sensitive data and applications in cloud and virtualized environments.
Benchmark Comparisons
In real-world benchmark tests, the AMD EPYC 7R32 consistently outperforms the AMD EPYC 7R13 due to its higher core count and clock speeds. For example, in the SPECrate2017_int_base benchmark, which measures integer performance, the EPYC 7R32 achieved a score of 1677, while the EPYC 7R13 scored 1281. Similarly, in the SPECrate2017_fp_base benchmark, which measures floating-point performance, the EPYC 7R32 scored 1276, while the EPYC 7R13 scored 1004.
Summary: Choosing the Right Processor for Your Needs
The AMD EPYC 7R32 and AMD EPYC 7R13 are both excellent server processors that offer exceptional performance and efficiency. The EPYC 7R32 is the better choice for applications that require high core counts, multi-threaded performance, and large memory bandwidth. On the other hand, the EPYC 7R13 is a more energy-efficient option that is suitable for applications that prioritize cost-effectiveness and security.
Questions You May Have
Q: Which processor is better for virtualization environments?
A: Both the AMD EPYC 7R32 and AMD EPYC 7R13 support AMD’s SEV technology, making them suitable for virtualization environments. However, the EPYC 7R32 has a higher core count and memory bandwidth, which can provide better performance for virtualized workloads.
Q: What is the difference between TDP and power consumption?
A: TDP (Thermal Design Power) is the maximum amount of heat that a processor is designed to dissipate under typical operating conditions. Power consumption, on the other hand, is the actual amount of power that the processor consumes, which can vary depending on the workload and operating environment.
Q: Is the AMD EPYC 7R32 backwards compatible with older motherboards?
A: No, the AMD EPYC 7R32 is not backwards compatible with older motherboards. It requires a motherboard that supports the SP3 socket and the AMD EPYC 7003 series processors.
