Intel introduces Core Ultra 2: i9-15900K/i7-15700K with Up to 24 Cores, No Hyper-Threading

Intel has recently launched its latest processors, the Core Ultra 2 series, which includes the i9-15900K and the i7-15700K. These high-end CPUs are part of Intel’s 15th Gen Arrow Lake-S lineup and come with impressive specifications.

Starting with the Core i7-15700K, this processor boasts 20 cores and 20 threads, similar to its predecessor, the 14700k. However, one notable difference is the absence of hyper-threading. This means that the CPU tile consists of 8 P-Cores and 12 E-Cores, providing a powerful computing experience. The base frequency of the cores is 2.3 GHz, with the E-cores likely responsible for this clock speed.

While the Core i7-15700K offers impressive performance, it does lack certain features such as AVX-512 support and Spectre V1, V2, and Speculative Store Bypass Mitigations. The latter is known to impact performance, so it will be interesting to see how this omission affects the overall capabilities of the processor. On the I/O side, the CPU supports several USB 4 and USB 3 ports, ensuring connectivity options for various devices.

Moving on to the Core i9-15900K, this processor takes things up a notch with 24 cores and 24 threads. Similar to the i7-15700K, it also lacks hyper-threading. The CPU is divided into 8 P-cores and 16 E-cores, utilizing the Lion Cove and Skymont architectures respectively. With a base clock of 3GHz and paired with 32GB of DDR5 memory, the i9-15900K promises exceptional performance for demanding tasks.

Interestingly, there have been rumors surrounding the fabrication process of the Arrow Lake CPUs. Initially thought to be an Intel 20A product, recent speculation suggests that the high-end desktop and mobile dies will be manufactured using TSMC’s N3B (3nm) process. Only lower-end 6+8 dies will be based on the Intel 20A node. Additionally, the iGPU will be fabricated on TSMC’s 4nm (N4P) process, potentially leaving the IO die as the sole Intel tile, similar to the Meteor Lake architecture.

Overall, Intel’s Core Ultra 2 processors, the i9-15900K and i7-15700K, offer impressive specifications and performance capabilities. With a focus on core count and powerful architecture, these CPUs are poised to deliver exceptional computing power for both high-end desktops and mobile devices. As Intel continues to innovate, it will be fascinating to see how these processors perform in real-world applications and how they stack up against competitors in the market.
