The Asus Prime Z270-A & GIGABYTE Z270X-Ultra Gaming Motherboard Review

Test Bed and Setup

Readers of our motherboard review section will have noted the trend in modern motherboards to implement a form of MultiCore Enhancement / Acceleration / Turbo (read our report here) on their motherboards. This does several things, including better benchmark results at stock settings (not entirely needed if overclocking is an end-user goal) at the expense of heat and temperature. It also gives in essence an automatic overclock which may be against what the user wants. Our testing methodology is ‘out-of-the-box’, with the latest public BIOS installed and XMP enabled, and thus subject to the whims of this feature. It is ultimately up to the motherboard manufacturer to take this risk – and manufacturers taking risks in the setup is something they do on every product (think C-state settings, USB priority, DPC Latency / monitoring priority, overriding memory sub-timings at JEDEC). Processor speed change is part of that risk, and ultimately if no overclocking is planned, some motherboards will affect how fast that shiny new processor goes and can be an important factor in the system build.

For reference, both the Asus Prime Z270-A and the GIGABYTE Z270X-Ultra Gaming had multi-core acceleration enabled by default. We tested the Asus Prime Z270-A with the 0604 BIOS and the GIGABYTE Z270X-Ultra Gaming with the F6 BIOS.
