Intel Core i7-8700K and Core i5-8400 Processor Review – Coffee Lake
Discrete GPU Gaming Performance
Thief
Thief is a series of stealth video games in which the player takes the role of Garrett, a master thief in a fantasy/steampunk world resembling a cross between the Late Middle Ages and the Victorian era, with more advanced technologies interspersed. Thief is the fourth title in the Thief series, developed by Eidos Montreal and published by Square Enix on February 25, 2014. We picked this game title for CPU testing as it is known to scale well with CPUs. We use the games built-in benchmark and test with the default settings with these changes; exclusive fullscreen, vSync off, 1920 x 1080, 60Hz.
Deus Ex: Mankind Divided
Deus Ex: Mankind Divided is an action role-playing stealth video game developed by Eidos Montreal and published by Square Enix. Set in a cyberpunk-themed dystopian world in 2029, two years after the events of Human Revolution, Mankind Divided features the return of Adam Jensen from the previous game, Deus Ex: Human Revolution, with new technology and body augmentations. The game was released on August 23rd, 2016 for PC users and we are using it to show DX12 performance on the CPUs that we tested. DX12 removed most all of the CPU overhead, so we wanted to see what happens to performance on DX12 game titles as well. We use the games built-in benchmark and test with the default settings with these changes; DX12 enabled, exclusive fullscreen, vSync off, 1920 x 1080, 60Hz, medium graphics.
Discrete Gaming Benchmarks Results Summary: These might not have been the best game titles to pick for benchmark, but at the time we wanted simple and repeatable benchmarks to show 1080P gaming performance. (Yes, we regret picking them now) It looks like we’ve hit a wall on Deus Ex: Mankind Divided where we are GPU limited and the Thief results show barely any difference between the 7700K and 8700K in stock form, but when both were overclocked to 5.1GHz the 8700K mysteriously pulls ahead by over 10 FPS on average. We ran that benchmark 5 times, restarted the system and the results were the same. The sub $200 Intel Core i5-8400 was on the upper half of the chart and looks like it would make a solid gaming processor with 6-physical cores.
