SuperPi Benchmark does show the single-thread performance of the CPU, so it was expected for the Ryzen 5 1400 to lose in both cases.
The X265 Benchmark from HWBOT allows the user to calculate the rendering performance of the processor. The Ryzen 5 1400 is the slowest from the bunch at the stock speeds, but again, it is able to match the 1500X SKU at stock, when overclocked.
3DMark Vantage does seem to show the same performance differences as before and in this synthetic benchmark we do also have a surprising win over the Intel Core i5 7600K (both stock and overclocked).
3DMark 11 shows the Ryzen 5 1400 at the bottom placement, because of its lower stock speeds but also the smallest cache size from the Ryzen 5 series.
3DMark 2013 does again show a big difference between the Ryzen 5 1400 and the Ryzen 5 1500X (even when the R5 1400 is overclocked!).
Unigine Valley is another 3D benchmark which benefits clock speed, so the Ryzen 5 1400 results are pretty self-explanatory here.
The Ashes of the Singularity benchmark is showing again the Ryzen 5 1400 processor capable to match the Ryzen 5 1500X only with its all-core overclock at 3.8GHz.
