Test Configuration and Benchmarks

We’ve covered the high-, middle- and low-end price ranges for X399. Today we’re going to use some samples from across the spectrum to see where the ASRock X399 Phantom Gaming 6 falls in terms of performance, overclocking, and overall design. Our test bench hasn't changed since the platform launched, so our data is for the most part comparable across the samples. With that said, some driver or Windows updates might have impacted performance, but not to a large degree

Our synthetic PCMark ’08 data shows a bit of variation across the samples, with the largest gaps coming in the Work, Office, Home workloads. The largest gap is seen with Work, and that unfortunately takes our favorite Gigabyte Aorus Gaming 7 down to last place by quite a margin. Sandra Arithmetic picks no favorites, and each board under the microscope gets wins in one category or another. Multimedia scores are not favoring the Phantom Gaming 6, scoring it 9 percent behind the Aorus Xtreme. However, Cryptography shines a ray of hope upon the Phantom, and its Memory Bandwidth squeaks ahead of the Gigabyte flagship board by a few GB/s. On average, our IOmeter storage benchmark shows mixed results across the samples, again proving that we are often splitting hairs in these performance analyses.
