Technical characteristics Intel Core i9-12900K
Socket: LGA1700
CPU socket, socket is the type of connector for connecting the processor to the motherboard. When we say "processor socket", we mean by this that a socket is both a socket on the motherboard and the support of this socket by certain processor lines. The socket of the motherboard and processor must be the same (compatibility). The socket is needed so that you can easily replace a failed processor or upgrade the system with a more productive processor.
Bus: 8 GT/s
The processor system bus (FSB — Front Side Bus) is a set of signal lines used to exchange information between the CPU and internal devices (RAM, ROM, timers, I/O ports, etc.) of the computer. The FSB actually connects the processor to the rest of the devices in the system unit. The bus frequency is the clock frequency at which data is exchanged between the processor and the computer's system bus. The amount by which the processor frequency exceeds the bus frequency is called a multiplier. All modern motherboards support the FSB frequency of any processors. The only compatibility criterion in this case remains the socket. On older models, this indicator was indicated in MHz, on modern models, the technology is indicated. DMI (Direct Media Interface) — Intel. HT (HyperTransport) — AMD. QPI (QuickPath Interconnect) — Intel.
Process size: 7 nm
Processors consist of millions and billions of tiny transistors that turn on and off to perform calculations. This requires power, and the smaller the transistor, the less power is required. In addition, the smaller the process, the more transistors fit on a chip of the same area, which means that performance is higher in this processor.
Die Size: No data
The area of the processor core (mm2) is the size of the processor chip. The value is not necessarily symmetrical, but can be in the form of a rectangle with equal parallel faces.
Transistors: No data
The more transistors in the processor, the higher its performance, after all, you can put more logic elements on the crystal to perform different operations.
Housing type: No data
The type of processor case.
Frequency: 2400 MHz
An indicator of the speed of execution of commands by the central processor. The unit of a cycle (one clock cycle) is considered to be 1 Hz (Hertz). A clock cycle is the time interval required to perform an elementary operation. This means that at a frequency of 1 GHz (Giga Hertz), the processor core performs 1 billion cycles (clock cycles). In the recent past, the clock frequency of the CPU was directly identified with its performance, that is, the higher the clock frequency of the processor, the more productive it is. In practice, we have a situation where processors with different frequencies have the same performance, because they can execute a different number of instructions per clock cycle (depending on the design of the kernel, cache memory, etc.). But you need to pay attention to the fact that the performance comparison is directly without any tests, based on clock frequencies, this is true only for processors with the same architecture (only processors of the same manufacturer and the same generation). The processor clock frequency is proportional to the system bus frequency.
Boost clock: 5200 MHz
Technology for automatically increasing the processor clock frequency above the nominal one. The maximum possible clock speed in Turbo mode, which is achieved when conditions allow the processor to switch to Turbo mode. Turbo Boost is used in Intel processors, Turbo Core - in AMD processors.
Base clock No data
Multiplier: No data
The processor multiplier is a hardware identifier that is transmitted to the BIOS or UEFI (interfaces between the operating system and the motherboard software). If you increase the multiplier, the clock frequency of the processor will increase. And with it, the performance of the system.
Unlocked multiplier: Yes
The unlocked processor has an unlocked clock frequency multiplier, which allows you to quickly and easily overclock it. A blocked processor cannot be overclocked in this way, only with overclocking of BCLK or the base (main) frequency.
tCaseMax: 100°C
tCaseMax indicates the maximum temperature that the upper center of the processor heat distributor should not exceed.
TDP: Typical TDP: 241 W
A value indicating the average heat dissipation of the processor in operation under load. The greater the power, the greater the requirements for the cooling system.
Cores Intel Core i9-12900K
Cores: 16
The processor core is an independent unit that executes certain commands. Modern manufacturing technologies of processors allow you to place more than one core in one case. The number of cores is one of the main characteristics of processor performance, it means a distributed load between them, the more cores, the higher the processor performance, but this does not mean that the presence of n cores gives an increase in performance by n times. In addition, the problem with multi-core processors is that there are relatively few programs available today, which are written taking into account the presence of a processor with multiple cores. The multicore nature of the processor, first of all, allows you to implement the multitasking function: distribute the work of applications between processor cores. This means that each additional core performs an additional stream of computing operations in parallel.
Streams: 24
A thread, or virtual core, is the result of the implementation of calculations, in which one physical core is able to programmatically divide its performance and work on several sequences of commands simultaneously. Multithreading allows you to increase the speed of the device.
Multiprocessing (SMP): No data
Symmetric Multiprocessing (SMP) is a multiprocessor architecture in which two or more identical processors are connected to a common memory. Most modern multiprocessor systems use the SMP architecture. SMP systems allow any processor to work on any task, regardless of where the data of this task is stored in memory, With proper operating system support, SMP systems can easily move tasks between processors, effectively distributing the load.
Cache Intel Core i9-12900K
L1 Cache: 1 MB
Cache memory is a high-speed computer memory designed for temporary storage of information. Level 1 cache (L1) is the local cache of the processor core, the memory area into which the processor writes frequently used data (in fact, RAM for your processor). The fastest, but at the same time the smallest in volume. Stores instructions and data separately. The cache memory of the first level is located on the same chip with the processor and operates at the CPU frequency (hence the highest performance) and is used directly by the processor core. The cache capacity of the first level is small and is calculated in kilobytes
L2 Cache: 14 MB
Cache memory is a high-speed memory designed for temporary storage of information. Level 2 cache (L2) is the local cache of the processor core. Faster than level 3 cache, but slower than level 1. Significantly more in terms of level 1 cache volume. The difference between L1 and L2 is that the latter has a lower speed, but a larger volume (from 128 KB to 12 MB), which is very useful for performing resource-intensive tasks. Stores instructions and data together.
L3 Cache: 30 MB
Cache memory is a high-speed computer memory designed for temporary storage of information. Level 3 cache (L3) is a shared cache for all processor cores. The slowest of all caches, but it is common, which allows you to store the data necessary for all processor cores in it. It works together with L1 and L2 cache memory to improve computer performance, preventing problem areas due to too long sampling and execution cycle. The L3 cache passes the information to the L2 cache, which then redirects the information to the L1 cache. Third-level cache memory is found in powerful computers.
Memory Intel Core i9-12900K
RAM support: DDR4-3200,DDR5-4800
The type of compatibility of processor memory and RAM.
Memory channels: 2
Interaction of the processor with RAM, in which the data transfer rate between them can be increased by using several channels at once to access the combined memory bank. The more channels, the higher the data transfer rate between memory and processor.
ECC Memory: Yes
This is a special type of RAM with built-in hardware error correction. These memory modules were developed specifically for servers, where the requirements for data accuracy and reliability of their processing are much higher than on personal computers. ECC memory automatically recognizes spontaneous data changes in memory blocks, i.e. errors that have occurred.
Periphery Intel Core i9-12900K
PCI Express Revision: PCI Express 5.0
PCI-E (Peripheral Component Interconnect Express) is a data exchange line between the processor and devices.
Number of PCI-Express lines: 20 declension_lines
PCI-E lines are the connecting "threads" in the operation of all components of a modern system. That is why it is important for any platform to have enough such "threads" to maintain the necessary data exchange speed between all PC components. The more lines there are, the higher the data transfer rate between the processor and memory.
