  • Intel's Core i5-14400 CPU features 10 cores, including 6 P-cores and 4 E-cores
  • Intel is optimizing its Core i5 1×400 SKUs in each generation by mixing silicons for better yields
  • The CPU is expected to deliver solid performance when released


Intel is making progress with its upcoming Core i5-14400 CPU, which is rumored to feature 10 cores, specifically 6 P-Cores and 4 E-Cores. Recently, a leaked list of Intel’s 14th Gen Core desktop CPUs revealed that the Core i5-14400 SKU is being evaluated in two possible variants: C0 and B0 silicons. Interestingly, this variation has also been observed with previous models like the Core i5-13400 and i5-12400.

Contrary to what the leaked spec list indicated, both the C0 and B0 silicons are expected to have the same core configuration of 6 P-Cores and 4 E-cores. While the chart from YuuKi-AnS initially listed the QDF code as Q3XZ with 8 E-cores, screenshots provided by ECSM suggest that both silicon revisions will be locked to a 4 E-Core configuration. Samples of the Intel Core i5-14400 have been obtained, indicating progress in its development.

Although it is not entirely clear what the B0 and C0 die revisions mean for Raptor Lake Refresh, it is worth noting that the Core i5-13400 also utilized similar die revisions. The newer B0 die featured 8 P-Cores and 16 E-Cores, while the C0 die was a leftover from Alder Lake’s top SKU configuration of 8 P-Cores and 8 E-Cores.

According to HWCooling, who delved deeper into the story, the Core i5-13400 CPUs with B0 silicons were primarily shipped on trays to system integrators, while the retail version in a box with Laminar RM1 cooler used the C0 silicon. Therefore, obtaining a B0 silicon was relatively rare, but it was possible to differentiate between the two by comparing S-SPEC codes or examining the backside of the CPU once unboxed.

Overall, it seems that Intel is aiming to optimize its Core i5 1×400 SKUs in each generation by mixing silicons for better yields. While this may not always be a significant factor for gamers, some silicons may offer different cache configurations. However, in the case of the i5-14400, this should not be a concern. The CPU is expected to be released early next year alongside other 65W non-K Raptor Lake Refresh models.

In summary, Intel’s Core i5-14400 CPU is shaping up to be an intriguing addition to the 14th Gen Core lineup. With its 10 cores, including 6 P-cores and 4 E-cores, it promises to deliver solid performance. As we await its official release, it will be interesting to see how it compares to its predecessors and the competition in the market.

Technology Explained


CPU: The Central Processing Unit (CPU) is the brain of a computer, responsible for executing instructions and performing calculations. It is the most important component of a computer system, as it is responsible for controlling all other components. CPUs are used in a wide range of applications, from desktop computers to mobile devices, gaming consoles, and even supercomputers. CPUs are used to process data, execute instructions, and control the flow of information within a computer system. They are also used to control the input and output of data, as well as to store and retrieve data from memory. CPUs are essential for the functioning of any computer system, and their applications in the computer industry are vast.


E-Cores: E-Cores (Efficiency Cores) are a type of technology used in the computer industry to provide a more efficient and reliable way of powering and cooling computer components. They are made up of a combination of copper and aluminum, and are designed to be more efficient than traditional copper cores. E-Cores are used in a variety of applications, such as in CPUs, GPUs, and other computer components. They are also used in servers, laptops, and other electronic devices. The technology is designed to reduce heat and power consumption, while also providing a more reliable and efficient way of powering and cooling computer components.


P-Cores: P-Cores (Performance Cores) are a type of processor technology developed by Intel that is designed to improve the performance of computer systems. This technology is based on the concept of multi-core processors, which are processors that contain multiple cores or processing units. P-Cores are designed to increase the speed and efficiency of computer systems by allowing multiple cores to work together in parallel. This technology is used in a variety of applications, including gaming, video editing, and data analysis. P-Cores are also used in servers and other high-performance computing systems. The technology is also used in mobile devices, such as smartphones and tablets, to improve battery life and performance. P-Cores are an important part of the computer industry, as they allow for faster and more efficient computing.
