480m 485m
570m 580m
670m 670mx 675m 680m 680mx
770m 780m
870m 880m
960m 965m 970m 980m gtx980
Mx150 1050 1050ti 1060 1070 1080

Arranged by series oldest to newest. Some are no more then 10% less performance to the HD 7770

Not really...

480m = 598 GFLOPS

485m = 883.2 GFLOPS
https/www.techpowerup.com/gpu-specs/geforce-gtx-485m.c390

570m = 772.8 GFLOPS
https/www.techpowerup.com/gpu-specs/geforce-gtx-570m.c1495

580m = 952.3 GFLOPs
https/www.techpowerup.com/gpu-specs/geforce-gtx-580m.c940

670m = 803.7 GFLOPS
https/www.techpowerup.com/gpu-specs/geforce-gtx-670m.c548

675M = 952.3 GFLOPS
https/www.techpowerup.com/gpu-specs/geforce-gtx-675m.c343

670mx = 1164 GFLOPS ie 1.164 TFLOPS (getting close now)
https/www.techpowerup.com/gpu-specs/geforce-gtx-670mx.c1413

ETC...

It's not till you hit the 680M and arguably the 770M, up you match or exceed the HD 7700 in power.

770M - 1.53 TFLOPS or 1530 GFLOPS
https/www.techpowerup.com/gpu-specs/geforce-gtx-770m.c2129

hd 7770 = 1.28TFLOPS or 1280 GFLOPS

The 480m for example is less then 1/2 the performance rated at 46% of the power. I am not sure how you came up with your numbers but they are very very flawed. I am happy to help you narrow down a proper list of mobile GPUs with xbox one equivalent power if you like.

If making your list within 10% of the performance of the XB1. So 10% less then, equal to or greater than XB1...(so everything ≥ 1152 GFLOPS or 1.152TFLOPS makes the cut). So then the list looks more like this:

670mx 680m 680mx
770m 780m
870m 880m
960m 965m 970m 980m gtx980
1050 1050ti 1060 1070 1080

The mx150 actually falls short of 1152 GFLOPS at 1127 GFLOPS so it gets dropped as well.

I used videocardbenchmark to determine

Synthetic benchmarks are not really great numbers to use for this type of comparison. Honestly the comparison is hard in general as it can never be apples to apples. This is why I went with the bare metal compute power. It is the closest you can get to apples to apples considering the OS and slight uArch differences compared to off the shelf PC parts and PC OS. Point being the list I put together is far more accurate in actually considering the compute power of each mobile GPU.
