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.
On Fire Strike, the three CPUs performed the same way.
On the Sky Diver benchmark, the Core i7-7700 also performed similarly to the Core i7-7700K and the Core i5-7600K.
On the Cloud Gate benchmark, the Core i7-7700 was 4% slower than the Core i7-7700K and 10% faster than the Core i5-7600K.
