ASRock B860 Pro RS Intel Core Ultra DDR5 8666 MHz vs ASRock Intel Core Ultra Z890 LGA1851 RL-ILM Mini

Overview of the Products

The ASRock B860 Pro RS is priced at $129.99, while the ASRock Intel Core Ultra Z890 is available for $249.99, making the latter about 92% more expensive. Both motherboards are designed for Intel Core Ultra processors, but they cater to different user needs and performance levels. The B860 Pro RS is an ATX model, while the Z890 is a Mini ITX, which influences their size, features, and intended applications.

Performance Capabilities

The ASRock B860 Pro RS supports DDR5 memory up to 8666 MHz, while the Z890 pushes that limit further with support for memory speeds up to 9466 MHz. This difference of 800 MHz in maximum memory speed implies that the Z890 may provide better performance in memory-intensive tasks. Moreover, the B860 Pro RS features a 10+1+1+1+1 power phase design, compared to the Z890's 12+1+1+1+1 configuration, indicating that the Z890 is built to deliver slightly more stable power for overclocking and extreme workloads.

Expansion Options

When it comes to expansion capabilities, the ASRock B860 Pro RS offers a PCIe 5.0 x16 slot along with additional PCIe 4.0 slots, providing ample room for next-gen GPUs and other peripherals. In contrast, the Z890 includes 2 Thunderbolt 4 Type-C ports for enhanced connectivity, which is particularly beneficial for users looking to connect multiple high-speed devices. The B860 Pro RS's greater number of M.2 slots, including a Blazing M.2 (PCIe Gen5 x4), offers more options for storage expansion, making it more versatile in this regard.

Connectivity Features

Connectivity is a key differentiator between the two motherboards. The ASRock B860 Pro RS boasts robust connectivity options, including USB 3.2 Gen2 and Gen1 ports, in addition to Thunderbolt 4 Type-C. The rear I/O features various USB ports that enhance its versatility. The Z890, while also offering strong connectivity with 2 Thunderbolt 4 ports, focuses on a more streamlined setup with fewer USB options. This makes the B860 Pro RS a better choice for users requiring extensive USB support for multiple devices.

Audio and Networking

The ASRock B860 Pro RS provides a comprehensive audio experience with its Realtek ALC1220 7.1 channel HD audio codec, enhanced by Nahimic Audio for immersive sound. This feature is particularly appealing for gamers and multimedia professionals. The Z890, while designed for stability and efficiency, does not highlight its audio capabilities as prominently, focusing instead on its overall performance and reliability. Both motherboards feature robust networking options, with the B860 Pro RS offering Realtek 2.5G LAN and WiFi 6E, ensuring excellent performance for online gaming and streaming.

Design and Build Quality

The B860 Pro RS is designed with military-grade components and features a Lite Release Design for easier GPU installation, making it an excellent option for DIY builders. The Z890 emphasizes a sleek, compact design, suitable for space-constrained setups, but may sacrifice some ease of installation due to its Mini ITX form factor. The choice between these designs will largely depend on personal preferences and specific use cases, such as gaming versus general productivity.

User-Friendly Features

Both motherboards include user-friendly features, but they prioritize different aspects. The B860 Pro RS boasts an optimized BIOS tuning and user-friendly UEFI, making it more accessible for beginners and those new to overclocking. On the other hand, the Z890 includes a Memory OC Shield, which can be beneficial for users looking to push memory limits further but may require more technical knowledge to utilize effectively. This difference may influence the choice for users based on their experience level and comfort with motherboard settings.

Which should you buy?

Choosing between the ASRock B860 Pro RS and the ASRock Intel Core Ultra Z890 largely depends on your specific needs and budget. If you are looking for a more affordable option with extensive expansion capabilities and robust connectivity, the B860 Pro RS, priced at $129.99, would be the ideal choice. However, if you require higher memory speeds and prefer a compact Mini ITX design for a more streamlined setup, the Z890, at $249.99, offers advanced features worth the investment. Ultimately, your decision should hinge on whether you prioritize budget and expandability or cutting-edge performance and compact design.
