I have seen the article about mantle not supporting the 7670m on toms hardware but on amd's website it says that it supports the 7000m series.

Can someone please explain if it is or isnt ever getting support because there are many conflicting articles.

Mantle will not work to any architecture prior to GCN. if you're not confident with my answer you can ask AMD themselves in their forum :) . Toms Hardware did an interview with Dice Johan Andersson about Mantle last year:

Johan: Mantle requires a certain set of key functionality of the GPU, so it can’t be supported on older architectures before AMD’s GCN architecture. The focus right now for Mantle is to...

Mantle specifically needs GCN based architecture. for desktop part it is less confusing then mobile. for example all AMD 7000 series for desktop part is GCN based but the mobile one some model (usually the lower end one) will using old architecture from previous generation. this is due to OEM routine that usually asking gpu vendor to rebrand old part as a new part so they can have something 'new' each year. it happen to both AMD and nvidia.

Thank you for the quick answers. This article says different and i also find it hard to believe that GNC is necessary.
DX12 is supposed to cut it down to the metal and that requires no modification to the architecture of the NVIDIA stuff.

Johan: Mantle requires a certain set of key functionality of the GPU, so it can’t be supported on older architectures before AMD’s GCN architecture. The focus right now for Mantle is to finish the implementation of the first version of it, and get it out together with a Mantle-based rendering back-end in Battlefield 4. This back-end will only be able to run on AMD’s GCN-based GPUs. Again, going forward I would like to see a future version of Mantle support GPUs from more vendors, and that would be a discussion that would have to happen between AMD, the other vendors, and us developers to figure out a way to make it happen.

one of the very reason why some people did not believe Mantle will simply work on other hardware than AMDs'. it did not work in 6k and 5k series (despite both still DX11 card) because the lack of needed hardware for Mantle how can anyone know that Mantle will outright work with nvidia hardware when the architecture is very different.
