3DMark is a program with a set of several 3D benchmarks. Fire Strike benchmark measures DirectX 11 performance and is targeted to high-end gaming computers. Sky Diver also measures DirectX 11 performance, and is aimed on average computers. The Cloud Gate benchmark measures DirectX 10 performance. The Ice Storm measures DirectX 9 performance and is targeted to entry-level computers, so we did not include it on our comparison.
Keep in mind that we used a GeForce GTX 980 Ti video card on all tests.
On the Fire Strike benchmark, the performance was the same on both configurations.
On the Sky Diver benchmark, we also had similar performances.
On the Cloud Gate benchmark, it was not different; the performance with both configurations was the same.
