About the AMD EPYC 7742 CPU

The AMD EPYC 7742 is a 64-core (128-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 7742 is compatible with AMD Socket SP3 motherboards and is fabricated on TSMC's 7 nm manufacturing process.

Memory and Cache

The EPYC 7742 supports DDR4 memory and features a octa-channel memory controller, allowing it to utilize 8 memory modules simultaneously. In terms of cache, the EPYC 7742 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 7742 features 64 total cores which can process 128 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 3.4 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 7742 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 Ryzen Threadripper 3970X CPU

The AMD Ryzen Threadripper 3970X is a 32-core (64-thread) processor built for the desktop CPU market. It launched in Q4 2019 with a suggested retail price of $1,999. It is part of AMD's Ryzen Threadripper lineup, which is based on the Zen 2 microarchitecture. The Threadripper 3970X is compatible with AMD Socket TRX4 motherboards and is fabricated on TSMC's 7 nm manufacturing process.

Memory and Cache

The Ryzen Threadripper 3970X supports DDR4 memory and features a quad-channel memory controller, allowing it to utilize 4 memory modules simultaneously. In terms of cache, the Ryzen Threadripper 3970X 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 128 MB.

Cores and Clock Speeds

The Ryzen Threadripper 3970X 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 3.7 GHz, and it can boost up to 4.5 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 Ryzen Threadripper 3970X does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
