Description
Intel i9-12900 Processor - 16-Core 2.4 GHz - Smart Cache launched in Q1'22, brings Alder Lake performance to desktop systems with a hybrid 16-core (8P+8E) design.
The 12th gen Intel® Core™ i9-12900 combines eight high-performance cores and eight efficient cores to deliver up to 5.1 GHz boost frequency and a base performance-core clock of 2.4 GHz. With 24 threads and a 30 MB Smart Cache, it is engineered for demanding multitasking and heavy workloads.
Built for LGA 1700 motherboards, this processor supports DDR4 and DDR5 memory in dual-channel mode and up to 128 GB of RAM, offering a maximum memory bandwidth of 76.8 GB/s. ECC support and advanced platform features make it suitable for workstation-class reliability.
The integrated Intel UHD Graphics 770 enables basic and light content tasks without a discrete GPU, supporting up to four displays and resolutions as high as 7680 x 4320 via DisplayPort and 4096 x 2160 via HDMI 2.1. Its media engines and Quick Sync Video accelerate encoding and decoding workloads.
Power and thermal characteristics include a 65 W base power and up to 202 W maximum turbo power, with a Tjunction of 100 °C. The CPU supports PCIe 5.0/4.0 with up to 20 lanes and flexible configurations for high-speed graphics and storage.
Security, management, and virtualization are comprehensive: Intel® VT-x/VT-d, Intel® AES-NI, Intel® Clear Video, Intel® Trusted Execution Technology, Intel® vPro™ eligibility, Total Memory Encryption, and Control-flow Enforcement Technology are all supported to protect and manage modern systems.
Typical use cases include high-end gaming rigs, professional content creation and video editing workstations, and demanding productivity PCs that benefit from hybrid core scheduling and high single-thread boost. The tray package and wide compatibility make it a strong choice for both system builders and upgraders.
Key highlights:
- 16 cores (8P + 8E) and 24 threads with up to 5.1 GHz boost
- 30 MB Smart Cache and support for DDR4/DDR5 up to 128 GB
- Integrated Intel UHD Graphics 770 with multiple high-resolution outputs
