3DMark is a program with a set of several 3D benchmarks. Fire Strike runs a “heavy” DirectX 11 simulation. Sky Diver also measures DirectX 11 performance, and is aimed on average computers. The Cloud Gate benchmark measures DirectX 10 performance, and the Ice Storm Extreme measures DirectX 9 performance and is targeted to entry-level computers, so we don’t ran it.
On Fire Strike, the Core i3-7100 was 4% faster than the Core i3-6100.
On the Sky Diver benchmark, the Core i3-7100 was 6% faster than the Core i3-6100.
On the Cloud Gate benchmark, the Core i3-7100 was 4% faster than the Core i3-6100.
