Summary
About the AMD EPYC 7642 CPU
The AMD EPYC 7642 is a 48-core (96-thread) processor built for the server CPU market. It launched in Q3 2019. It is part of AMD's EPYC lineup, which is based on the Zen 2 microarchitecture. The EPYC 7642 is compatible with AMD Socket SP3 motherboards and is fabricated on TSMC's 7 nm manufacturing process.
Memory and Cache
The EPYC 7642 supports DDR4 memory and features a octa-channel memory controller, allowing it to utilize 8 memory modules simultaneously. In terms of cache, the EPYC 7642 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 96 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 512 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 256 MB.
Cores and Clock Speeds
The EPYC 7642 features 48 total cores which can process 96 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.4 GHz, and it can boost up to 3.4 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.
Integrated Graphics
The EPYC 7642 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
About the AMD FX-8120 CPU
The AMD FX-8120 is an end-of-life 8-core (8-thread) processor built for the desktop CPU market. It launched in Q4 2011. It is part of AMD's FX lineup, which is based on the Zambezi microarchitecture. The FX-8120 is compatible with AMD Socket AM3+ motherboards and is fabricated on a 32 nm manufacturing process.
Memory and Cache
The FX-8120 supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the FX-8120 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 384 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 8 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 8 MB.
Cores and Clock Speeds
The FX-8120 features 8 total cores which can process 8 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.1 GHz, and it can boost up to 4.0 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.
Integrated Graphics
The FX-8120 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
