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 Intel Xeon W-3265M CPU

The Intel Xeon W-3265M is a 24-core (48-thread) processor built for the workstation CPU market. The Xeon W-3265M is compatible with FCLGA3647 motherboards.

Cores and Clock Speeds

The Xeon W-3265M features 24 total cores which can process 48 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2700.0 MHz, and it can boost up to 4400.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.

Integrated Graphics

The Xeon W-3265M does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
