CPU Cache
A CPU cache is fast memory close to processor cores that stores frequently accessed instructions and data.
View definitionCPU Core
A CPU core is an execution unit within a processor that runs instructions independently of other cores.
View definitionCPU Frequency
CPU frequency describes a processor clock rate, usually measured in gigahertz, and can vary with workload.
View definitionCPU Thread
A CPU thread is a logical execution context presented to software by a physical processor core.
View definitionCPU Turbo Boost
CPU turbo boost temporarily raises clock speed within processor power and thermal limits.
View definitionDDR4
DDR4 is a generation of synchronous dynamic RAM used in computers and servers.
View definitionECC Memory
ECC memory detects and corrects certain memory bit errors to improve system reliability.
View definitionHyper-Threading
Hyper-Threading is Intel's form of simultaneous multithreading, allowing one core to expose multiple logical processors.
View definitionL1 Cache
L1 cache is a small, very fast processor cache usually located within each CPU core.
View definitionL2 Cache
L2 cache is a processor cache larger and typically slower than L1, reducing accesses to main memory.
View definitionL3 Cache
L3 cache is often shared across CPU cores and helps reduce traffic to system RAM.
View definitionLoad-Reduced DIMM (LRDIMM)
LRDIMM is server memory that buffers data and control signals to reduce electrical loading and support compatible high-capacity configurations.
View definitionNUMA
Non-Uniform Memory Access is a multiprocessor design where memory access latency depends on processor and memory location.
View definitionNUMA Node
A NUMA node groups processors and nearby memory with relatively fast local access.
View definitionNVMe
A storage protocol designed for fast SSD connected via PCI Express.
View definitionRegistered DIMM (RDIMM)
RDIMM is registered server memory that buffers command and address signals; compatibility depends on the processor and motherboard.
View definitionSimultaneous Multithreading (SMT)
Simultaneous multithreading lets a physical CPU core execute instructions from multiple hardware threads.
View definitionSMART
A telemetry system integrated with the discs to track certain health indicators.
View definitionThermal Throttling
Thermal throttling reduces processor or GPU performance when temperature exceeds a configured limit.
View definitionTPM
A security chip or function that protects cryptographic keys and start-up measures.
