Hybrid architecture, which implies a combination of high-performance (Performance-cores) and energy-efficient (Efficient-core) cores. Support for DDR5 standard and PCI Express 5.0 interface.
Performance-cores are high-performance cores capable of simultaneously executing up to two computation threads. Efficient-core — energy-efficient cores do not support Hyper-Threading and are designed to handle background workloads.

Intel Core i9-12900K Alder Lake LGA 1700 30MB Smart Cache Processor Intel Trusted Execution Technology for safer comput... moreing is a versatile set of hardware extensions to Intel processors and chipsets that enhance the digital office platform with security capabilities such as measured launch and protected execution. It enables an environment where applications can run within their own space, protected from all other software on the system. Intel Virtualization Technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) and Itanium processor (VT-i) virtualization adding new support for I/O-device virtualization. Intel VT-d can help end users improve security and reliability of the systems and also improve performance of I/O devices in virtualized environments. Intel Virtualization Technology (VT-x) allows one hardware platform to function as multiple virtual platforms. It offers improved manageability by limiting downtime and maintaining productivity by isolating computing activities into separate partitions. Intel 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms when combined with supporting software.¹ Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory. 12th Gen Intel Core i9 Processor Generation Alder Lake Processor Codename 30 MB Processor Cache 5.2 GHz Processor Boost Frequency Smart Cache 125 W Processor Base Power Instruction Set Extensions Instruction Set Extensions are additional instructions which can increase performance when the same operations are performed on multiple data objects. These can include SSE (Streaming SIMD Extensions) and AVX (Advanced Vector Extensions). Intel Turbo Boost Max Technology 3.0 Intel Turbo Boost Max Technology 3.0 identifies the best performing core(s) on a processor and provides increased performance on those cores through increasing frequency as needed by taking advantage of power and thermal headroom. Intel Gaussian & Neural Accelerator Intel Gaussian & Neural Accelerator is an ultra-low power accelerator block designed to run audio and speed-centric AI workloads. Intel GNA is designed to run audio based neural networks at ultra-low power, while simultaneously relieving the CPU of this workload.

The flagship of the Alder Lake family
Core i9-12900K contains 8 high-performance cores and 8 power-efficient cores, however, the total number of threads reaches 24 instead of 32, since 8 auxiliary cores do not support Hyper-Threading technology. As for the frequency characteristics, the main cores can be overclocked up to 5.2 GHz, while the speed of the auxiliary ones is limited to 3.9 GHz. Plus, the Core i9-12900K is equipped with 30 MB L3 cache + 14 MB L2 cache, supports 16 PCI-E 5.0 bus lines. Or with four PCI-E 4.0 lanes. In addition to everything, the processor can work both with the usual DDR4 memory and with the new DDR5.
Ryzen 9 5900X competitor
What did all these improvements give? In most synthetic benchmarks that focus on instantaneous multithreading, the Core i9-12900K is slightly ahead of the competing Ryzen 9 5900X and 5950X chips. The excess is from 5 to 15%. Although there are also reverse examples, when the Ryzen 9 5950X, on the contrary, goes ahead by the same 10 – 12%. In gaming benchmarks, Intel still managed to regain leadership - in FarCry 6, Forza Horizon and F1 2021, the Core i9-12900K processor always turns out to be 8-12% faster than the Ryzen 9 5950X competitor.
unhealthy appetite
But here it is important to make two clarifications. First, AMD Vermeer processors came out a year ago, so the comparison is not entirely correct. The real fight for the championship belt is scheduled for early 2022, when the new Ryzen 6000 chips will be released with the new 3D V-Cache, which promises the same 15% increase in pure power. The second important nuance is that Intel CPUs pay for their acceleration with increased power consumption. If the power consumption of the system with the Ryzen 9 5950X was 221 watts, then the Core i9-12900K requires a little more than 350 watts. The final 130 W is not the most beautiful reverse side of the coin, which calls into question the victory of the Core i9-12900K. After all, it needs a more powerful power supply, and a more serious cooling system.
