Notes:

This table is based on publicly available information and may not be completely accurate.
“Unconfirmed” features require further verification from official sources.

Core Functionality: A Solid Foundation

Both chipsets share some core functionalities. They utilize the DMI 4.0 x8 interface for communication with the CPU, and boast compatibility with a wide range of Intel Xeon processors, including the Sapphire Rapids family.

Additionally, they offer support for Intel Optane memory, maximizing storage performance, and essential security features like Trusted Execution Technology and vPro.

Scalability and Power: Cater to Your Needs

The key differentiator lies in scalability and power. The C741 shines in these aspects. It supports dual-socket configurations (1S or 2S), allowing for up to 8 TB of memory with two CPUs installed.

This caters to users who need extreme processing power and memory capacity, ideal for tasks like large-scale simulations or complex data analysis. Additionally, the C741 offers up to 80 lanes of PCI Express 5.0 for processor communication, ensuring maximum data transfer speeds between the CPU and other components.

However, with a slightly higher TDP (Thermal Design Power) of 11 W, it generates a bit more heat.

The W790, on the other hand, is designed for single-socket workstations (1S only). Its memory capacity is limited to 4 TB, catering to users who prioritize performance but don’t require the extreme scalability of the C741.

It offers a slightly lower TDP of 6 W, resulting in cooler operation. However, it compensates for the lower memory capacity with support for the faster USB 3.2 Gen 2×1 standard, offering double the bandwidth compared to the C741’s USB 3.2 Gen 1.

Additionally, the W790 boasts integrated Intel Wi-Fi 6E for convenient wireless connectivity, a feature missing in the C741.

The Overclocking Advantage: For Performance Enthusiasts

For those seeking to push their hardware to the limit, the W790 offers a significant advantage: overclocking support. This allows experienced users to manually adjust CPU clock speeds for an extra performance boost.

However, overclocking can lead to instability and increased heat generation, so it’s important to have proper cooling solutions in place.

Choosing Your Champion: Consider Your Needs

Ultimately, the best chipset for you depends on your specific needs. If you require extreme scalability, raw processing power, and a large memory footprint, the C741 is the clear winner.

However, if you prioritize features like overclocking, integrated Wi-Fi, and a slightly cooler operating temperature while still maintaining excellent performance, the W790 is a compelling choice.
