The P-cores are also higher at 3.6 GHz, but the turbo is 4.9 GHz, with the favored core at 5.0 GHz. Over the Core i9, the E-cores in the Core i7 have a higher base frequency at 2.7 GHz, but a lower turbo frequency of 3.8 GHz. This leads to an 8P+4E design, with 20 total threads. Core i7-12700K/KFįor the Core i7, Intel has removed one set of four E-cores, and also reduced the 元 cache to 25 MiB. At 105W/142W, AMD has the power advantage, but Intel has PCIe 5.0 and DDR5 support, with the K also having integrated graphics. Intel has more actual cores, but AMD has more high-performance cores. On price, the Core i9 parts are up against the Ryzen 9 5900X (12C/24T, 3.7-4.8 GHz) at $549. As these are 1000-unit prices, retail is expected to be $10-$50 higher, depending on how Intel bundles the chip. The 1000-unit price for the K model is $589, and the KF model without integrated graphics as $564. Intel lists the base power as 125 W, with a turbo power of 241 W. With all the cores active, the system has all 30 MiB of 元 cache available. The P-cores that are considered the best (aka favored cores) will turbo up to 5.2 GHz. Core i9-12900K/KFįor the Core i9-12900K, if we work from the ground up, the E-cores have a base frequency of 2.4 GHz but will turbo up to 3.9 GHz the P-cores have a base frequency of 3.2 GHz, and an all-core turbo of 5.1 GHz. Prices will start at $264 for the base Core i5 model, up to $589 for the top Core i9 model. The K processors also feature 32 EUs of Intel’s Xe-LP graphics, designated as UHD Graphics 770. Memory support is listed as both DDR5-4800 and DDR4-3200, although systems will only support one or the other, for a maximum of 128 GB. The way power is marketed and used has also changed, designed to be clearer.Īll processors will come with 16 lanes of PCIe 5.0 from the processor, and an additional 4 lanes of PCIe 4.0 for storage. But with a new hybrid design also comes with new ways to showcase frequencies, and each set of cores will have its own base frequency and turbo frequency. Inside the system, the P-core threads, E-core threads, and SMT threads are categorized for performance and efficiency, which we’ll get to later in the article.
The P-cores have SMT, whereas the E-cores do not, so we’re dealing with non-standard numbers of total threads. This is the table: Intel 12th Gen Core, Alder LakeĮach processor has a number of performance cores (P-cores) and efficiency cores (E-cores).
As with previous launches, we have Core i9, Core i7, and Core i5, with the key highlights including new support for DDR5, PCIe Gen 5, new overclocking features, and a change in how Intel is promoting its Thermal Design Power (TDP). The first things we’ll go into are the new CPUs that Intel is announcing today: the overclockable models of Intel 12 th Gen Core. The goal was for this event to be in-person, which is usually where the most value came from the old IDF event, however this is the first attempt to revive the format.
It includes a day one keynote from CEO Pat Gelsinger and other executives to share the new hardware announcements, and a day two keynote from CTO Greg Lavender on the software side. As part of the event, there are 60+ sessions designed to cover new technology such as AI, networking, custom silicon, programming technologies/challenges, and introduce developers to more of Intel’s ecosystem. This event is, as described in a number of press releases, a mini-Intel Developer Forum (IDF) event designed to emulate a small part of the highly prized annual conference that the company culled in 2017. Today’s announcement also coincides with Intel’s InnovatiON virtual event happening today and tomorrow. We have specifications, details, and insights ahead of the product reviews on November 4 th. Only the six high-performance K and KF processor variants are coming this side of the New Year, with the rest due for Q1.
Alder Lake contains Intel’s latest generation high-performance cores combined with new high-efficiency cores for a new hybrid design, along with updates to Windows 11 to improve performance with the new heterogeneous layout. Alder Lake, commercially known as Intel’s 12 th Generation Core architecture, is officially being announced today for a November 4 th launch. Over the past few months, Intel has been drip-feeding information about its next-generation processor family.
