We tested a total of 12 CPU’s, starting with 4c/4t models (Core i5 7600K) and up to 10c/20t models (Intel Core i9 7900X). Unfortunately, we did not have a Coffee Lake Core i3 for this review, so we only tested the new Core i5 and Core i7 versions, namely Intel Core i5 8600K and the Intel Core i7 8700K. For those who are curious how high the Core i5 8600K can be overclocked for daily use, we tested it both at stock frequency and overclocked at 5100MHz. Please keep in mind that in our tests COre i5 8600K ran at 4.3GHz on all cores, while Core i7 8700K ran at 4.7GHz on all cores, so testing the Core i7 at 5GHz would have not made too much sense.
For Intel Core i5 7600K and Intel Core i7 7700K we used an AORUS Z270 Gaming 9 motherboard, while the LGA 2066 processors were tested on the MSI X299 Raider. The AMD Ryzen 7 1800X, 1700X, 1700 and Ryzen 5 1600X were tested on the AORUS X370 Gaming 5. For all the CPU’s we used the latest BIOS available on the manufacturer’s website.
We used a GSkill TridentZ 16GB DDR4-3200 CL16 memory kit for all platforms except X299, where we used a GSkill TridentZ RGB 32GB DDR4-3200 CL14 kit. All CPU’s were cooled with a Noctua NH-D15, equipped with a factory fan, powered by a Seasonic P1200 power supply.
We used the best GTX 1080 implementation we had in the lab, namely the Zotac GTX 1080 AMP Extreme, along with the WHQL Forceware 384.94 driver. Windows 10 Pro x64, with all the upgrades up to date, was installed on a 1TB Samsung 850 Evo SSD. We only use updated operating systems, benchmarks and games.
The system was tested on the HSPC Top Deck Station open test bench, with ambient temperatures around 28 oC. We have tried to get a complete set of tests to answer the questions of a wider range of readers. Thus, we have both synthetic tests and real applications, as well as a series of overclockers benchmarks.
