Gaming performance

Let's see how good Core i3-8100 and Core i3-8109U are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately. Also, your gaming PC must have a decent enough GPU to perform well.

Advantages of Intel Core i3-8100

41.1% better performance in benchmarks

Cheaper ($237 vs $592)

ECCMemory

Advantages of Intel Core i3-8109U

More powerful video core

Somewhat newer (5 April 2018 vs 5 October 2017)

Higher base clock speed (3000 vs 2800 MHz)

Lower power consumption (28W vs 65W), meaning that the rival with higher TDP might require a better cooler or other thermal solution.

HyperThreading (allows one physical CPU function as two logical ones. It increases performance, since while one logical CPU is waiting for data, the second may still do useful work)

Quick Sync (hardware acceleration of video encoding and decoding for Intel CPUs. Speeds up video encoding by times, but at the cost of somewhat lower quality)

Virtualization (Hardware acceleration of virtual machines)

AES-NI (Advanced Encryption Standard New Instructions - additional instructions for hardware acceleration of AES encryption and decryption)
