Gigabyte A520I AC vs GIGABYTE Z790 AORUS Elite AX LGA 1700 ATX

Overview of the Gigabyte A520I AC and Gigabyte Z790 AORUS Elite AX

The Gigabyte A520I AC is priced at $99.99, making it about 47% cheaper than the Gigabyte Z790 AORUS Elite AX, which costs $189.99. Despite the price difference, each motherboard serves distinct user needs, targeting different segments of the market. The A520I AC is designed for compact builds and offers support for AMD Ryzen processors, while the Z790 AORUS Elite AX is tailored for high-performance gaming with support for Intel's latest processors.

Processor Compatibility

The A520I AC supports 3rd Generation AMD Ryzen processors with an AM4 socket, providing compatibility for a broad range of AMD CPUs. In contrast, the Z790 AORUS Elite AX is built for Intel's LGA 1700 socket and supports the 14th, 13th, and 12th Generation Intel Core processors. This gives the Z790 board a more advanced edge in terms of speed and performance capabilities, catering to gamers and professionals who wish to harness the latest technology.

Memory Support

The memory configurations of these motherboards are quite different. The A520I AC supports dual-channel DDR4 memory with two DIMM slots, which may limit performance in memory-intensive applications compared to the Z790 AORUS Elite AX. The latter is compatible with DDR5 memory and features four SMD DIMMs with XMP 3.0 support, allowing users to optimize their memory performance further. This difference makes the Z790 AORUS Elite AX a more future-proof option for those looking to push their systems to the limit.

Power Delivery Systems

Power delivery is crucial for stable performance, especially in gaming and high-performance tasks. The A520I AC utilizes a Direct 6 Phases Digital PWM with 55A DrMOS, providing adequate power for its target user. In contrast, the Z790 AORUS Elite AX boasts a more commanding power design with a 16+1+2 Phases Digital VRM solution featuring 70A power stages. This superior design allows the Z790 model to deliver better power efficiency and stability, essential for overclocking and demanding applications.

Connectivity Options

Connectivity is a strong suit for both motherboards, but they cater to different needs. The A520I AC includes a single NVMe PCIe 3.0 x4 M.2 slot and supports a fast 1GbE LAN, along with Intel Dual Band AC WiFi and Bluetooth. Meanwhile, the Z790 AORUS Elite AX offers more advanced connectivity with four PCIe 4.0 x4 M.2 slots, USB 3.2 Gen 2x2 Type-C, and 2.5GbE LAN. This makes the Z790 board much more versatile for modern peripherals and faster data transfer rates.

Thermal Management

Thermal management is vital for maintaining performance and longevity in high-demand scenarios. The A520I AC features an optimized VRM heatsink designed to dissipate heat effectively. However, the Z790 AORUS Elite AX takes thermal management a step further with its M.2 Thermal Guard III and fully covered MOSFET heatsinks. These enhanced thermal designs ensure that the Z790 model can handle the heat generated during intensive tasks, making it a better choice for gamers and professionals who require peak performance.

Aesthetic Features

Both motherboards come with aesthetic features that might attract different users. The A520I AC has an RGB Fusion 2.0 capability, allowing for some customization of lighting effects, making it suitable for users who appreciate a bit of flair in their builds. The Z790 AORUS Elite AX also features RGB Fusion, but with a more advanced implementation, alongside a sleek design that caters to high-end builds. This makes the Z790 model more appealing for those who value both performance and visual aesthetics.

Which should you buy?

Choosing between the Gigabyte A520I AC and the Z790 AORUS Elite AX largely depends on your specific needs and budget. If you are looking for an affordable option for a compact build and plan to use an AMD processor, the A520I AC at $99.99 is a solid choice. However, if you prioritize performance, plan to use the latest Intel processors, and need advanced connectivity and power delivery, the Z790 AORUS Elite AX at $189.99 is worth the investment. Ultimately, your decision should align with your intended use case and budget constraints.
