256MB L3 cache
The EPYC 7551 is equipped with a massive 256MB of L3 cache, which serves as a high-speed buffer between the processor cores and main memory.
The L3 cache stores frequently accessed data and instructions, reducing the need to fetch data from the slower main memory. This significantly improves performance, especially for applications that work with large datasets or frequently access the same data.
The large L3 cache also reduces memory latency, which is the time it takes to access data from memory. This is particularly important for latency-sensitive applications, such as real-time analytics and online transaction processing.
Overall, the 256MB L3 cache in the EPYC 7551 provides a significant performance boost by minimizing memory access time and increasing data availability.
Up to 3.7 GHz boost clock
The EPYC 7551 features a boost clock speed of up to 3.7 GHz, which indicates the maximum clock speed that individual cores can reach when handling demanding tasks.
Clock speed is measured in gigahertz (GHz) and represents the number of cycles a processor can execute per second. A higher clock speed allows the processor to perform more operations in a given amount of time, resulting in faster performance.
The 3.7 GHz boost clock speed of the EPYC 7551 provides a significant performance boost for single-threaded applications and tasks that require high clock speeds. This makes it ideal for workloads such as gaming, video editing, and CAD/CAM software, where fast and responsive performance is crucial.
However, it's important to note that the boost clock speed is not sustained indefinitely. The processor may adjust its clock speed dynamically based on factors such as temperature, power consumption, and workload demands to maintain optimal performance and efficiency.
PCIe 4.0 support
The EPYC 7551 supports PCIe 4.0, which is the latest generation of the Peripheral Component Interconnect Express (PCIe) interface.
- Increased bandwidth: PCIe 4.0 offers double the bandwidth of PCIe 3.0, enabling faster data transfer speeds between the processor and peripherals such as graphics cards, storage devices, and network adapters.
- Reduced latency: PCIe 4.0 has a lower latency than PCIe 3.0, which means that data can be transferred more quickly with less delay. This is particularly beneficial for applications that require real-time data processing or low-latency communication.
- More lanes: The EPYC 7551 supports more PCIe 4.0 lanes than previous generations of EPYC processors, providing greater flexibility for connecting multiple high-speed devices simultaneously.
- Enhanced scalability: PCIe 4.0's increased bandwidth and reduced latency make it ideal for scaling up systems with multiple GPUs or other high-performance peripherals, enabling greater computational power and data throughput.
Overall, PCIe 4.0 support in the EPYC 7551 provides significant performance benefits for a wide range of applications, including data-intensive workloads, virtualization, and high-performance computing.
Security features
The EPYC 7551 incorporates advanced security features to protect against unauthorized access and data breaches:
Secure Encrypted Virtualization (SEV): SEV encrypts virtual machines (VMs) and their memory, protecting them from unauthorized access, even if the host system is compromised. This is particularly important for cloud computing and multi-tenant environments where multiple users share the same physical infrastructure.
Secure Memory Encryption (SME): SME encrypts the entire memory contents of the processor, including the operating system, applications, and data. This prevents unauthorized parties from accessing sensitive information, even if they have physical access to the server.
Secure Boot: Secure Boot ensures that only authorized firmware and software are loaded during the boot process, preventing malicious code from being executed.
AMD Infinity Guard: Infinity Guard is a hardware-based security technology that provides a secure communication channel between the processor and other system components, protecting against eavesdropping and data tampering.
Power efficiency
The EPYC 7551 is designed with power efficiency in mind, helping to reduce energy consumption and operating costs:
Precision Boost 2: Precision Boost 2 technology dynamically adjusts the processor's clock speed and voltage based on workload demands. This allows the processor to operate at higher speeds when needed while conserving energy during less demanding tasks.
AMD Power Management: AMD Power Management provides a comprehensive suite of features to optimize power consumption, including power capping, thermal monitoring, and energy-efficient power states.
7nm process technology: The EPYC 7551 is manufactured using a 7nm process technology, which enables greater transistor density and reduced power consumption compared to previous generations.
