Summary
About the AMD EPYC 7643 CPU
The AMD EPYC 7643 is a 48-core (96-thread) processor built for the server CPU market. It launched in Q1 2021 with a suggested retail price of $4,995. It is part of AMD's EPYC lineup, which is based on the Zen 3 microarchitecture. The EPYC 7643 is compatible with AMD Socket SP3 motherboards and is fabricated on TSMC's 7 nm manufacturing process.
Memory and Cache
The EPYC 7643 supports DDR4 memory and features a octa-channel memory controller, allowing it to utilize 8 memory modules simultaneously. In terms of cache, the EPYC 7643 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 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 7643 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 2.3 GHz, and it can boost up to 3.6 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 7643 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 E2-9000 CPU
The AMD E2-9000 is a 2-core (2-thread) processor built for the mobile CPU market. The E2-9000 is fabricated on a 28 nm manufacturing process.
Memory and Cache
In terms of cache, the E2-9000 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 256 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1 MB, is larger but slower than the L1.
Cores and Clock Speeds
The E2-9000 features 2 total cores which can process 2 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 1800.0 MHz, and it can boost up to 2200.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.
Integrated Graphics
The E2-9000 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
