2. The first EPYC processor was launched in 2017. AMD introduced the EPYC 7000 series, marking their return to the server CPU market.

3. EPYC stands for "Embedded Processor for Cloud." This name highlights the processor's primary target market: cloud computing and data centers.

4. EPYC CPUs support up to 64 cores. This high core count allows for exceptional parallel processing capabilities, making them ideal for demanding workloads.

5. They offer up to 128 threads. With simultaneous multithreading (SMT), each core can handle two threads, doubling the processing power.

Performance and Efficiency

AMD EPYC processors are known for their outstanding performance and energy efficiency. Let's dive into some key facts that showcase these attributes.

6. EPYC CPUs have a high memory bandwidth. They support up to 8 channels of DDR4 memory, providing fast data access and improved performance.

7. They feature a large L3 cache. With up to 256MB of L3 cache, EPYC processors can store more data closer to the cores, reducing latency and boosting performance.

8. EPYC processors support PCIe 4.0. This latest version of the PCIe interface offers double the bandwidth of PCIe 3.0, enabling faster data transfer between components.

9. They have a low thermal design power (TDP). EPYC CPUs are designed to be energy-efficient, with TDPs ranging from 120W to 280W, depending on the model.

10. EPYC processors use Infinity Fabric. This technology connects the CPU cores and other components, ensuring efficient communication and data transfer within the processor.
