Intel’s 15th Gen Core i5-15600: A Promising 8 P-Cores with 3 Gens of LGA1851 Motherboard Support

Intel is gearing up to release its 15th generation Core processors, codenamed Arrow Lake, in the latter half of 2024. These new processors will feature a fresh set of core architectures and process nodes, promising improved performance and efficiency. Among the lineup, the flagship desktop offering will come equipped with 8P (performance) and 16E (efficiency) cores, similar to the current Raptor Lake-S flagship.

Sitting below the flagship model, we have the Core i7 and the Core i5. While details about the Core i7 are scarce at the moment, rumors suggest that the Core i5 variant will sport 8 high-performance “P” cores, making it an impressive 8-core processor. This is a step up from its predecessor, the 13600, which featured 6P and 8E cores. It’s worth noting that the K variant of the Core i5 is expected to retain the E-Cores, albeit limited to a maximum of 6.

One notable improvement with the Arrow Lake processors is the cache system. The L2 cache per core and shared level will see an increase, with each core now enjoying 3MB of L2 cache per L3 cache. This represents a significant 50% boost compared to previous generations. Additionally, the L3 cache will be divided between the CPU and integrated GPU (iGPU), with the iGPU having its own LLC (last-level cache). This division helps alleviate strain on the CPU cache and enhances overall system performance.

In terms of compatibility, Intel is rumored to introduce the LGA1851 socket with the 15th Gen Arrow Lake processors. What’s interesting is that this socket is expected to be supported until 2026, spanning three generations of desktop processors. This means that users investing in a motherboard with an LGA1851 socket will have the flexibility to upgrade their processors without having to change their motherboard for at least three generations. However, it’s worth mentioning that Intel may still release new chipsets based on the same socket, as seen in the past with the Skylake architecture and its subsequent refreshes.

Overall, Intel’s 15th Gen Core i5-15600 appears to be a promising addition to the Arrow Lake lineup. With its 8 high-performance cores and improved cache system, users can expect a significant boost in processing power and efficiency. Furthermore, the long-term support of the LGA1851 socket ensures future compatibility and upgradability for desktop enthusiasts. As we eagerly await the arrival of these processors in the second half of 2024, it will be interesting to see how they stack up against the competition and whether they deliver on their promises of enhanced performance and user experience.

iGPU: An integrated Graphics Processing Unit (iGPU) is a component built into a computer's central processing unit (CPU) or system-on-chip (SoC) that handles graphical tasks. Unlike dedicated graphics cards, which are separate components, an iGPU shares system resources with the CPU, allowing for basic graphics capabilities without the need for an additional card. While typically less powerful than dedicated GPUs, iGPUs are energy-efficient and well-suited for everyday computing tasks
