About the AMD EPYC 7551 CPU
The AMD EPYC 7551 is a 32-core (64-thread) processor built for the server CPU market. It launched in Q2 2017. It is part of AMD's EPYC lineup, which is based on the Zen microarchitecture. The EPYC 7551 is compatible with AMD Socket SP3 motherboards and is fabricated on GlobalFoundries's 14 nm manufacturing process.
Memory and Cache
The EPYC 7551 supports DDR4 memory and features a octa-channel memory controller, allowing it to utilize 8 memory modules simultaneously. In terms of cache, the EPYC 7551 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 64 MB.
Cores and Clock Speeds
The EPYC 7551 features 32 total cores which can process 64 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2000.0 MHz, and it can boost up to 3.0 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 EPYC 7551 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 Core i7-9700KF CPU
The Intel Core i7-9700KF is an end-of-life 8-core (8-thread) processor built for the desktop CPU market. It launched in Q1 2019 with a suggested retail price of $374. It is part of Intel's Core i7 lineup, which is based on the Coffee Lake Refresh microarchitecture. The i7-9700KF is compatible with Intel Socket 1151 motherboards and is fabricated on Intel's 14 nm manufacturing process.
Memory and Cache
The Core i7-9700KF supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-9700KF 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 256 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 12 MB.
Cores and Clock Speeds
The Core i7-9700KF 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 3.6 GHz, and it can boost up to 4.9 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 Core i7-9700KF does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
