CPU Specifications

Total Cores
?
Cores is a hardware term that describes the number of independent central processing units in a single computing component (die or chip).
16
Total Threads
?
Where applicable, Intel® Hyper-Threading Technology is only available on Performance-cores.
32
Basic Frequency
4.5 GHz
Max Turbo Frequency
?
Max Turbo Frequency is the maximum single-core frequency at which the processor is capable of operating using Intel® Turbo Boost Technology and, if present, Intel® Turbo Boost Max Technology 3.0 and Intel® Thermal Velocity Boost. Frequency is typically measured in gigahertz (GHz), or billion cycles per second.

Max. Operating Temperature
?
Junction Temperature is the maximum temperature allowed at the processor die.
95°C
PCI Express Version
?
PCI Express Revision is the supported version of the PCI Express standard. Peripheral Component Interconnect Express (or PCIe) is a high-speed serial computer expansion bus standard for attaching hardware devices to a computer. The different PCI Express versions support different data rates.
PCIe® 5.0
Instruction Set
?
The instruction set is a hard program stored inside the CPU that guides and optimizes CPU operations. With these instruction sets, the CPU can run more efficiently. There are many manufacturers that design CPUs, which results in different instruction sets, such as the 8086 instruction set for the Intel camp and the RISC instruction set for the ARM camp. x86, ARM v8, and MIPS are all codes for instruction sets. Instruction sets can be extended; for example, x86 added 64-bit support to create x86-64. Manufacturers developing CPUs that are compatible with a certain instruction set need authorization from the instruction set patent holder. A typical example is Intel authorizing AMD, enabling the latter to develop CPUs compatible with the x86 instruction set.

Memory Specifications

Memory Type
?
Intel® processors come in four different types: Single Channel, Dual Channel, Triple Channel, and Flex Mode. Maximum supported memory speed may be lower when populating multiple DIMMs per channel on products that support multiple memory channels.
DDR5
Memory Channels
?
The number of memory channels refers to the bandwidth operation for real world application.
8
Bus Speed
Up to 6400 MT/s
ECC Memory Support
Yes (Default Enabled)

GPU Specifications

Integrated Graphics Model
?
An integrated GPU refers to the graphics core that is integrated into the CPU processor. Leveraging the processor's powerful computational capabilities and intelligent power efficiency management, it delivers outstanding graphics performance and a smooth application experience at a lower power consumption.
