100-000001458 - AMD Epyc Turin 9845 160C/320T 2.1GHz/3.7GHz 320MB 6000MT/s x128 390W 1P/2P

Processor Detailed Information

Cores

The combined operation of processor cores is known as multitasking.

Effective core cooperation maximizes system performance. Multi-core

processors are well-suited for virtualization and computation, while

fewer-core CPUs with higher clock speeds excel in single-thread

performance.

Cores: 160

Threads

Hyperthreading and multithreading technologies create virtual cores,

enhancing performance by enabling two virtual threads per physical

core. A typical server CPU features a 1:2 core-to-thread ratio.

Threads: 320

Frequency

The clock rate indicates how quickly a processor executes instructions.

Higher frequencies often improve performance, but multi-core processors

with lower frequencies may perform better in optimized tasks.

Base Clock: 2.1 GHz

Max Turbo Clock: 3.7 GHz

Cache

Cache memory (L1, L2, L3) accelerates data access. Processors with

more cores generally have larger caches, such as AMD EPYC processors

with up to 256 MB of L3 cache.

L3 Cache: 320 MB

Memory Compatibility

Consider the maximum memory capacity and frequency supported by the

processor. Exceeding the supported frequency will result in memory

being downclocked to the processor's maximum capability.

TDP

Thermal Design Power (TDP) represents the maximum heat output that

the cooling system must dissipate, corresponding closely to energy

consumption.

TDP: 390W
