Windows 10 Benchmarking DX12

Windows 10 will see the release of DX12 which like AMD's Mantle see's the bulk of work spread across all the CPU's cores instead of just the first core taking all the brunt.

Now with the latest update of 3DMark (you'll need a full licence) users can see for themselves what a major change DX12 has the potential to bring.

You'll need the latest version of Windows 10 Preview Build 10041.

You will also need to use the GPU driver supplied by Windows Update as this is DX12 capable.

Here's some screenshots from my testing:




Guru3D also has a short article which details a little further on the aspect of this new API:

As you can see above my GPU certainly isn't the latest and anyone owning either Fermi (Nvidia) or GCN (AMD) based GPU will be able to run this bench.
