After months of teasers and architecture-level revelations, Intel’s ‘Alder Lake’ 12th Gen Core i9, Core i7, and Core i5 CPUs have been released for gaming, workstations, and enthusiastic desktop PCs. Six new models, all of which are unlocked and overclockable, have been released. For the first time in an X86 PC, the customer introduces a mix of heterogeneous performance and performance cores with these new CPUs, which are the first in the ‘Alder Lake’ family. It also ushers in DDR5 RAM and the PCIe 5.0 interconnect standard.
Intel is calling its new 12th Gen ‘Alder Lake’ CPUs ‘Performance Hybrid Architecture,’ which combines two different core types. This works in a similar way to how ARM-based smartphone processors have been developed for a number of years. This single architecture will support all of Intel’s consumer CPU categories, with various core types and mixes. The newly renamed 10m ‘Intel 7’ process will be used to manufacture all 12th Gen Core CPUs.
Specifications And Features Of The CPUs
The new ‘Golden Cove’ Performance (P) cores in the current ‘Tiger Lake’ architecture replace the ‘Willow Cove’ cores, while the ‘Gracemont’ Efficiency (E) core architecture is a descendant of the former Intel Atom CPU range. Intel’s first hybrid CPU, codenamed ‘Lakefield,’ was released in 2020, but it has only been seen in a few real-world devices. The 16 cores (8 P + 8 E) in the 12th Gen desktop Core i9 CPUs announced so far, while 12 cores (8 P + 4 E) in Core i7 models and 10 cores (6 P + 4 E) in Core i5 models.
Background tasks and more multi-threaded tasks can be assigned to the E core, while the P core is for high-impact light threaded workloads. Also, P cores continue to benefit from hyperthreading, which allows two threads to run at the same time, but E cores do not, resulting in non-linear core/thread counts in the 12th Gen Core CPU. Intel has developed a new dynamic scheduler called the Thread Director to balance workloads and ensure that the best tasks are assigned to each type of core. This requires Windows 11, and Intel claims that performance on Windows 10 and other operating systems will not be optimized. Thread Director will prioritize the P cores first, then the E cores, and only after those are fully utilized will thread be assigned to the P cores’ Hyper-Threading capacity.
The L2 caches of each P core are private, whereas the L2 caches of clusters of four E cores are shared. These feed into a standard L3 cache, allowing for fast knowledge transfers and low latency in workloads that are optimized for each core type. Based on the Xe LP architecture, CPUs without the -F suffix will also have built-in Intel UHD 770 graphics.
The new Z690 platform controller has been released, and 12th Gen Core desktop CPUs now use the LGA1700 socket, which is larger. This generation’s platform features include the first use of DDR5 RAM, with official support for 128GB (dual-channel) at 4800MT/s with XMP 3.0 profiles. DDR4-3200 RAM is also supported, with motherboard manufacturers choosing which standard to use depending on the model. Alder Lake CPUs have up to 16 PCIe 5.0 lanes, which doubles the bandwidth of PCIe 4.0. Overclocking controls for the CPU and RAM have also been added.
The Core i9-1200K is billed as “the best gaming processor in the world,” with Intel claiming that it outperforms the octa-core Core i9-11900K in gaming and content creation workloads. It has a clock speed of 5.2GHz. The base and turbo speeds of two different core types are 2.4-3.9GHz for E cores and 3.2-5.1GHz for P cores. 125W and 241W are the base and peak power ratings, respectively.
The P cores have a 19 percent gen-on-gen efficiency boost, according to Intel. The Core i9-12900K is said to have a 50 percent higher multi-threaded efficiency than the Core i9-11900K, with a peak energy consumption of 241W instead of 250W. Efficiency is up to 30% higher at the rated 125W inventory TDP, whereas the same level of efficiency can be achieved within a 65W power limit. Intel claims that when gaming and streaming at the same time, body charges increase by up to 84 percent. That figure is said to be 47 percent when exporting edited video while processing RAW photographs. It is claimed that performing these tasks sequentially rather than concurrently is faster.
The Core i9-12900KF, which has nearly identical specifications, as well as the Core i7-12700K, Core i7-12700KF, Core i5-12600K, and Core i5-12600KF, round out the lineup. The -F suffix indicates that the model does not have integrated graphics, whereas the -K suffix indicates that it is unlocked and overclockable. Lower-cost versions of these CPUs are expected to debut in Q1 of next year, possibly as early as CES 2022.
Price And Availability Details
The top-end Core i9-12900K costs $589 (roughly Rs. 43,380 before taxes) in the US, while the Core i5-12600KF costs $264 (roughly Rs. 19,445 before taxes). Models without built-in graphics are only slightly less expensive than those with built-in GPUs. These are per-1000-item costs, which may or may not reflect retail prices. Regardless of global semiconductor scarcity, Intel expects strong retail availability, and a number of PC OEMs are also on board to deliver pre-built desktops. Official prices in India have yet to be confirmed, but some retail listings without prices appeared on the internet as recently as last week.
