OSX vs. Windows 10 scores, same hardware

Recommended Posts

I've built a Hackintosh that shows scores in the mid 2000's when Novabench is run in Windows 10, but mid 1000's when run in El Capitan.

Should the scores be relatively equal given equal hardware or are scores derived differently for each OS?

If they're not derived differently, then the OS X score should be higher - I'm running Windows 10 on a much slower drive while OS X is on a much faster SSD.

Here's the Windows 10 score.

And here's the OS X score.

The lower score in OS X seems to be because of the GPU. Is Novabench testing the GPU properly? I'm using the official Nvidia GTX960 drivers, and they appear to be working.

I'm still totally baffled. Running Geekbench 3 in 32bit (64bit costs money) it's relatively the same score in either OS.

Running GpuTest 0.7.0 shows results that are within 2-5% of each other in either OS.

Why is Novabench showing such different results?

Thanks for posting, it's an interesting question

The graphics test on Windows and Mac are built on completely different tech (OpenGL vs DirectX). Novabench accounts for this by making assumptions about how the different technology pipelines should behave, and adjusts the final score accordingly.

Normally this works well enough and Novabench scores the same (with small % variance) in graphics for macOS and Windows in bootcamp on Apple hardware. But the scoring assumptions can be completely off on a Hackintosh. There are a lot of possible factors, but it probably comes down to different optimizations in the driver Apple ships vs. the Nvidia alternative drivers.

It's hard to write cross-platform graphics that behave the same, especially with Apple still shipping an outdated OpenGL version. The next version of Novabench will include an additional GPU Compute test, based on newer tech, that should leave much less room for variance.

Bottom line: your 970 is probably performing as well as it can
