The Haswell micro-architecture in Devil's Canyon processors is just the latest Intel CPU architecture to see many of the critical system operations handled by the processor. As such, benchmarking a motherboard becomes more of a test to certify that the part operates correctly and meets the anticipated performance levels.
We will be outlining the Asus Maximus VII Impact motherboard's performance with the Core i7 4790K CPU at its stock frequency (4.4GHz due to forced turbo). Overclocked performance will be outlined later in the review.
By default, the Asus Maximus VII Impact motherboard applies multi-core turbo (MCT) and forces the 4790K to a constant 4.4GHz when XMP is enabled. This will be displayed as the ‘stock’ setting.
CPU-Z (using the latest version) reports a VCore delivery of around 1.26V when MCT was applied. This is slightly higher than the VCore level that we have seen other Z97 boards provide the 4790K.
