Intel Arrow Lake-S: Enhanced Performance & SSD Support

In exciting news for the electronics industry, Intel's highly anticipated Arrow Lake-S processor has been leaked by technology media Igor's LAB. The processor is set to feature the powerful Core Ultra brand, promising an impressive 21% increase in CPU performance. Additionally, the new architecture will deliver a doubling of the integrated graphics performance.

The flagship model of the Arrow Lake-S processor boasts an impressive design with 8 big cores and 16 small cores, mirroring the capabilities of the current flagship i9-13900K. Rumors also suggest the possibility of an even more powerful configuration with 8+32 cores.

One noteworthy change in the Arrow Lake-S processor is the introduction of the LGA 1851 socket, which closely resembles the existing LGA 1700 socket with some minor alterations. The most significant change lies in the number of contact pins, which has increased from 1700 to 1851, representing a notable 9% growth. However, the overall socket dimensions remain the same at 37.5mm x 45mm.

In terms of compatibility, the Z-height (the distance between the top of the motherboard and the CPU cover) remains nearly unchanged, although slight height differences have been reported. These differences can potentially be mitigated by using washers. However, it is important to note that the effectiveness of this solution is yet to be confirmed. Additionally, CPU cooler manufacturers are advised to apply an additional pressure of 923N for optimal performance.

To facilitate the smooth integration of the Arrow Lake-S processor into the market, Intel has already shared essential documentation with CPU cooler and AIO (All-in-One) manufacturers. These documents outline the changes specific to the Arrow Lake-S desktop CPU and LGA 1851 socket.

Intel's decision to introduce the new platform and socket with the Arrow Lake-S processor primarily stems from their ambition to match AMD's impressive I/O capabilities. While Intel's 600 and 700 series processors already offer extensive I/O features, they have recognized the need to enhance SSD support.

To address this, the Arrow Lake-S desktop CPU will include dedicated PCIe Gen 5 x4 channels, providing improved support for SSDs. These channels will complement the existing standard Gen 4x4 channels.

According to reports, Intel plans to launch the Arrow Lake-S desktop CPU alongside the 800 series motherboards featuring the LGA 1851 socket by the end of 2024.
