GTX 980M Slow speed

[Repentance]

I have the feeling that the speed of the GTX 980M is considerably slower on some methods and attack types than the AMD.

I own both a MSI GTX 980M and a AMD Radeon HD Sapphire 7850.
Yet my 2GB AMD ouperforms my 8GB NVIDIA card in some attack types and methods.
Yet in other methods it gives off a 4x to 8x more power, why is this and is there a way to fix it?

When I was trying some IPB hashes I also noticed it only used 50% of the GPU instead of 100%.


Does anyone have any idea's?

Stupid question: one is a notebook GPU (GTX980M) and one is sitting in a stand alone desktop?

Yes, unless they've been stuck somewhere really weird.

GTX 980M is not the same as a GTX 980. Mobile GPUs are slower due to power and heat constraints.

The amount of video memory is inconsequential for cracking performance, unless you're cracking scrypt or something.
