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 Mobile Pentium III 900 CPU

The Intel Mobile Pentium III 900 is an end-of-life 1-core (1-thread) processor built for the mobile CPU market. It launched in Q1 2001 with a suggested retail price of $562. It is part of Intel's Pentium III lineup, which is based on the Coppermine microarchitecture. The Mobile III 900 is compatible with Intel Socket 495 motherboards and is fabricated on Intel's 180 nm manufacturing process.

Memory and Cache

In terms of cache, the Mobile Pentium III 900 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 32 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 256 KB, is larger but slower than the L1.

Cores and Clock Speeds

The Mobile Pentium III 900 is a single-core and single-threaded CPU, making it not capable of processing multiple computational tasks in parallel. The base clock speed of the CPU is 900.0 MHz. Higher clock speeds result in higher performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Mobile Pentium III 900 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
