CINEBENCH 15 is a cross-platform testing suite that measures hardware performance and is the de facto standard benchmarking tool for leading companies and trade journals for conducting real-world hardware performance tests. With Release 15, systems with up to 256 threads can be tested.
CINEBENCH is available for both Windows and OS X and is used by almost all hardware manufacturers and trade journals for comparing CPUs and graphics cards.
The WT73VR 7RM is only 18 percent quicker than the WS63 7RK, but both have quad-core processors, and the WT73VR 7RM is only clocked a few hundred MHz faster, so this is no surprise. The WS-X143S also has a quad-core processor, but runs at 5GHz across all four cores, giving it a major advantage. The latest version of the WS-X143S's CPU, the Core i7-8700K, has six cores, so would have even more of an advantage.
In other words, the WT73VR 7RM is no slouch for rendering, but a notebook still can't compete with a desktop in this area. You can't use processors with as many cores, and you can't overclock them significantly either. So this notebook will be good for the odd test render on the road, but not serious production output.
The Cinebench OpenGL test is very sensitive to clock speed, so neither of the notebooks fare well against a desktop running at 5GHz. The WT73VR 7RM is only marginally better than its lighter, cheaper, and less powerful WS63 7RK sibling.
