Ryzen is looking pretty bad at the moment. The processor is designed similarly to the Core 2 Quad; two groups of four cores. A user over on Anandtech ran the draw call demo on 1 core, from each core group. Scored 14fps consistently.

Using two cores from only one core group, however, and he always scored 17fps.

The eight core versions should be avoided imo, but hopefully R5 and R3 versions have only one core group.

To throw in some more info, I've concocted a score for the draw call benchmark. FPS / (Ghz * 10). Makes for an easier graph to look at.

Skylake is looking real good.

But i dont get it, why my frame rate results are so high and old tests i had here? They were 3 times higher than amd cpu results, but yours do not differ that much

Were your tests using the same object values? 1 ship + 16000 rocks?

Drivers might also be making a difference, particularly if your tests were AMD CPU + AMD GPU vs Intel CPU + NVidia GPU.

Maybe it's the resolution/windows desktop composition (Aero)?

If the results from 2012 compared that, it probably was AMD's driver being inefficient, particularly at these identical draw call scenarios. Just a guess, admittedly.

Resolution makes no difference, and full screen only provides less than a single frame of performance difference. Gives my Phenom II +0.20fps. All the results were collected from the program in windowed mode.

But i don't understand why my result is so much better even compared to other Intel CPUs. Maybe vsync is forced?

Nope. Made sure that VSync was disabled. Here's the Anandtech thread: https://forums.anandtech.com/threads/pa ... e.2499609/

Edit: Your score is perfectly in-line with the NVidia GPU results. You mentioned the cause of this earlier; NV's driver is good at issuing the same draw call many times.
