Summary benchmark resultsAs a percentage of the maximum value based on a sample from the entire base of all processors
Processor Benchmark
| Core i7-8665U | 51% |
Core i3-8100B | 52% |
This value shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, Core i3-8100B is 1% better than Core i7-8665U. The data source is several popular tests. More detailed information of the benchmarks is below.
Gaming performance
Summary result of all game benchmarks.| Core i7-8665U | 52% |
Core i3-8100B | 52% |
The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. And of course, this is a server processor, on which no one will play games. Because the cost of this processor reaches several tens of thousands of dollars. And if it seems to you that the selected CPU has a small game result, look at the FPS that it produces in real games in the summary table below.
List of less popular games in which processors were compared: Shadow of the Tomb Raider, Counter-Strike: Global Offensive (CS GO), Control, PlayerUnknown's Battlegrounds (PUBG), Ghostrunner, Hitman 3, DOTA 2A, Resident Evil 7 Biohazard, Monster Hunter World, Horizon Zero Dawn, The Witcher 3: Wild Hunt, Microsoft Flight Simulator, League of Legends (LOL), Forza Horizon 4, Metro Exodus, Half-Life: Alyx, NBA 2K20, Battlefield V.
Gaming benchmark| Fortnite | 92.4 | 91.7 | | Valorant | 105.0 | 104.2 | | Cyberpunk 2077 | 58.8 | 58.3 | | Apex Legends | 98.7 | 97.9 | | Call of Duty Warzone | 78.7 | 78.1 | | Overwatch | 85.0 | 84.4 | | Red Dead Redemption 2 | 72.4 | 71.9 | | DOOM Eternal | 52.5 | 52.1 | | Warzone | 81.9 | 81.3 | | Assassin's Creed | 88.2 | 87.5 | | Valheim | 87.1 | 86.5 |
The numbers in this table indicate the maximum FPS that was received on the device with the corresponding processor. Depending on the configuration of the computer (RAM size and Video Card) and graphics quality settings (Ultra, Medium, Normal), the results may differ quite significantly. We recommend that you better study the results of the Cinebench, GeekBench and Passmark becnmarks.
The tested computers not only did they have different amounts of RAM and different video cards. But users also tested them at different screen resolutions: 2K, 4K or FullHD. Therefore, the game benchmark data is approximate. But all video cards met the average system requirements of games. To be sure exactly how much performance the processor will be in games, if you get acquainted with the benchmarks that are made with the same video card that is installed in your computer.
Power consumption
| Core i7-8665U | 273% |
Core i3-8100B | 48% |
To make a final resolution on which processor is better, you should also consider the generation of its core. The newer the processor generation, the better its performance in games and benchmarks, as well as its energy efficiency. In this case the Core i7-8665U is more energy efficient than the Core i3-8100B as it consumes less power: 15W vs. 65W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need to know its TDP. It is necessary to count so that the TDP data specified in the cooler specification is greater than the TDP of the compared processor.
Software benchmarksIf you want to use the processor not only for gaming, but also for machine learning, programming, video rendering or video editing, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum performance, the CPU includes all cores and threads that it has. You will find out this data from the benchmark tables below. Before you take into account the data from these tests, be sure to check whether the software you are going to use on your computer supports multi-threaded mode. Since there are still many programs that use only one core to work, and all the benefit of multi-core mode are unused.

Comparison of specifications
In the specification comparison table, the processor release date and overclocking capability will be the most helpful. The newer the processor, the longer it will last in your computer. And the easier it will be to upgrade the system later. The same can be said about overclocking. When the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS in new games. Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer. The economy are obvious!
